MISO Planning Subcommittee Briefs

MISO released a work plan last week detailing how it and PJM will use the next six months to improve coordination of generation retirements.

The RTOs’ cooperation on generator retirement studies was one of six directives mandated by MISO, PJM Working to Comply with NIPSCO Order.)

At last week’s Planning Subcommittee meeting, MISO said it and PJM will develop a proposal on retirement studies coordination by July.

MISO said it would work on the issue in meetings of the subcommittee, Planning Advisory Committee, and the RTOs’ Interregional Planning Stakeholder Advisory Committee and Joint and Common Market.

Neil Shah, MISO adviser of seams administration, said the RTOs would be starting from scratch. “The joint operating agreement doesn’t have any retirement coordination language,” he said.

miso planning subcommitteeThe RTOs differ on retirement rules. MISO requires 26 weeks’ notice prior to retirement, giving it time for a 75-day reliability assessment; PJM requires a 90-day notice and only 30 days of reliability assessment. Further, MISO keeps retirement information confidential unless a reliability concern is identified. PJM has no such confidentially rules and makes retirement information publicly available.

Shah said MISO would submit its work plan to FERC with an informational status filing that is due June 20. Additional status filings are due Aug. 19 and Oct. 18.

He also said MISO plans to share draft JOA language with stakeholders at the RTOs’ Nov. 15 joint and common issues meeting in time to file proposed JOA revisions with FERC by Dec 15.

Pseudo-Ties to Require System Impact Studies; Would be Barred from Sink Switching

MISO wants to conduct system impact studies on all pseudo-tied units with transmission service requests and forbid them from switching sinks until the requests expire.

The RTO is proposing a system impact study be required for all pseudo-tie transmission service requests and that firm point-to-point transmission service be required for the life of the pseudo-tie.

MISO has also proposed that pseudo-tied exports be sourced from a designated generating facility in its commercial model and be modeled in the external balancing authority. Pseudo-tied imports must be sourced from the local balancing authority where the generating unit is physically located and must sink into the MISO local balancing authority where the unit is being pseudo-tied.

“Participants are changing pseudo-ties to another sink after they have a transmission service request,” MISO senior transmission planning engineer Ankit Pahwa said. “It’s a shortcoming in the existing process … and a gray area that has not been covered yet.”

Pahwa said the proposed changes have been coordinated with PJM. He added that participants with existing pseudo-tied transmission service requests would be grandfathered from an impact restudy.

Currently, transmission service requests are evaluated based on an OASIS available flowgate capability evaluation, with only long-term requests — 18 months or longer — requiring a system impact study. Neither long-term nor short-term requests require a source/sink analysis, Pahwa said.

“From MISO’s perspective, we want to be 100% sure that we capture the transmission service impacts if a pseudo-tie moves to a different [local balancing authority],” Pahwa said.

“I think what we’re wrestling here is, does there need to be different treatment for pseudo-ties … much like there are different evaluations for network resource interconnection service for reliability purposes? At the minimum, you need to be sure you have the appropriate type of analysis,” MISO’s Jeff Webb said.

Webb said more conversations with other RTOs were needed before a final proposal. Stakeholders have until July 15 to comment on MISO’s proposal.

MISO Delves into MTEP 16 Studies

MISO is in the midst of developing model scopes for the 2016 Transmission Expansion Plan (MTEP 16), said Dave Ditner of the RTO’s system modeling department. The RTO’s modeling will include a 2017 summer peak with wind contributions of 15.6% and 2021 modeling of summer peak, summer shoulder and light load scenarios with wind contributions ranging from 15.6 to 90%.

MTEP16 Transfer Studies (MISO) MISO planning subcommittee

William Kenney, an expansion planning engineer for MISO’s Southern Region, also presented the finalized MTEP 16 voltage study scope. The study will use nine 2021 power flow models, including summer, winter and a shoulder with wind at 40%. MISO will release the final MTEP 16 voltage stability study in October.

Additionally, seven transfers will be studied in model year 2021 under the MTEP 16 transfer analysis scope:

  • MISO North to SPP;
  • Two different paths from Manitoba Hydro to MISO North;
  • PJM in Northern Illinois to PJM Ohio;
  • Missouri and Illinois to PJM Ohio;
  • SPP to Southern Co.’s territory; and
  • MISO South to SPP.

MISO will finalize the transfer analysis in mid-August.

Storage May Be Removed from Non-Transmission Alternatives

MISO presented stakeholders with draft language on Business Practices Manual 020, continuing a nearly yearlong discussion on non-transmission alternatives.

The RTO is suggesting separating energy storage devices that could solve a transmission issue from BPM language on non-transmission alternatives. MISO is also recommending discussion on whether storage can serve as a non-traditional transmission alternative move to the Planning Advisory Committee, MISO’s Matt Tackett said.

In April, MISO proposed classifying storage as a non-traditional transmission alternative. (See “Energy Storage Prompts 2nd Transmission Alternative Category,” MISO Planning Subcommittee Briefs.)

Indianapolis Power & Light’s Lin Franks said storage provides frequency control and voltage control much like transmission.

MISO will present a second draft of the BPM language at the August Planning Subcommittee meeting.

ERCOT Board of Directors Briefs

The ERCOT Board of Directors approved extending a reliability-must-run contract with NRG Energy for its Greens Bayou Unit 5 plant in the Houston area. The RMR, ERCOT’s first in five years, will run through June 30, 2018, at which time additional generation and transmission infrastructure is expected to be in service.

Greens Bayou
Greens Bayou Source: NRG

The 371-MW natural gas-fired generator was originally scheduled to be mothballed June 27, but ERCOT’s RMR contract June 3 made the unit available to the market through September. (See ERCOT to Keep NRG’s Greens Bayou Plant Running for Summer.)

Staff analysis indicates Greens Bayou Unit 5 is needed to maintain or support reliability in the region over the short term.

“Having that unit available will reduce the likelihood of having to engage a constraint-management plan, which would likely mean load shed,” said Warren Lasher, ERCOT’s director of system planning.

Under the RMR agreement’s terms, ERCOT will make a standby payment to NRG of $3,185/hour during on-peak hours, whether or not the unit runs.

Directors Carolyn Shellman, of CPS Energy, and Read Comstock, of Direct Energy, both encouraged additional discussion on the ISO’s RMR practices at the next board meeting. “I think we should encourage a holistic review of the RMR protocols,” Comstock said.

Lasher said staff will begin evaluating must-run alternatives, which it will bring to the board in August. The Technical Advisory Committee is also creating a task force to focus on the issue.

“I would like to see the market solve these situations, so we don’t have to,” Director Judy Walsh said.

Staff said the region’s reliability concerns will subside before the summer peak of 2018, when the $590 million Houston Import transmission project — “the ultimate [RMR] exit strategy,” Lasher called it — is expected to be completed. New generation is also on the way, with NRG’s 390-MW PH Robinson peaking facility expected to come online later this summer and Exelon’s 1,148-MW Colorado Bend combined cycle plant to follow in July 2017.

ERCOT also added 75 MW of power last week when NRG converted a gas turbine at its Houston-area W.A. Parish facility into a cogeneration unit. The unit was originally built to produce steam and electricity as part of the Petra Nova post-carbon capture and sequestration joint venture with JX Nippon Oil & Gas Exploration. The unit went into mothballs May 19 during its conversion process.

Magness: Mild Weather Cuts into Admin Revenue

CEO Bill Magness said ERCOT’s year-to-date revenues are $2.3 million over budget, despite a $2.2 million shortfall in the administrative fee that is attributed primarily to mild weather this year. He said the ISO is on track to finish $3.1 million above budget, thanks to positive variances in resource management, hardware and software, and employee benefit costs.

“It looks like we can create a favorable variance, but we don’t know what the weather’s going to be like,” Magness said.

ERCOT’s senior meteorologist, Chris Coleman, said this summer will “likely” not be as warm as last summer — the 17th hottest in Texas over the past 121 summers — or 2011, when sustained heat led to several peak-demand records and seven emergency alert notifications.

“This summer is one of the more difficult forecasts I’ve put together,” Coleman said. “Most indicators suggest a milder summer. I can guarantee you we will not see a repeat of 2011.”

Coleman said ocean temperatures, the primary influence on weather patterns, have been above normal in both the Pacific and Atlantic Oceans. He also said the transition from the second-strongest El Niño on record to what he expects to be a neutral or weak La Niña could lead to above-normal temperatures in the late summer.

The meteorologist said he does see “more potential for hurricane activity in the Gulf of Mexico” than his first four years with ERCOT. Coleman predicted five hurricanes, of which one or two could be in the Gulf, and the potential for two storms to make landfall in Texas.

“It doesn’t mean Texas will be hit by a tropical storm or hurricane,” he said, “but if there are three to five in the Gulf, the potential is greater.”

Dan Woodfin, ERCOT’s director of system planning, said it would take “really, really extreme” weather conditions to affect the grid’s operations. The ISO said last month it has more than enough natural gas and renewable energy capacity to meet its projected summer peak this year. (See ERCOT Briefs: Ample Capacity; Outage Procedures.)

“We’re not expecting a 2011 summer,” Woodfin said. “We have procedures in place should something out of the ordinary happen.”

The Rio Grande Valley, long a trouble spot for congestion, “looks better this summer than it has in quite a few years,” Woodfin said. He said a 345-kV line was completed last month and a cross-valley project went into service two weeks ago, easing some concerns.

LP&L Integration Could Unlock More Panhandle Wind Energy

Lasher shared staff’s report on how to integrate Lubbock Power & Light into ERCOT, which recommends a plan that would allow for further export of the Texas Panhandle’s ample wind energy supplies.

Lasher said staff’s “option 40W” will cost $364 million and result in 141 miles of new 345-kV rights of way, but it could also help export 4,246 MW of wind energy elsewhere on the grid.

“It’s not the low-cost option,” he said, “but it’s preferred specifically because it’s consistent with the longer-term needs ERCOT has identified for the region.”

LP&L announced last September it planned to disconnect from SPP and join ERCOT by 2019. Xcel Energy, whose Southwestern Public Service subsidiary serves LP&L’s load, asked FERC in May for an $88.7 million interconnection switching fee should the municipal utility proceed with its plan. (See Xcel Asks for $88.7M Fee for Lubbock Switch to ERCOT.)

Staff combined studies supplied by LP&L and Sharyland Utilities, which has transmission assets in the Panhandle, and folded them into its own analysis. The final report will be filed in the Public Utility Commission of Texas’ LP&L docket (# 45633).

Changes to Calculation of Market’s Physical Responsive Capability

ERCOT’s methodology for determining ancillary service requirements will change July 1 when it adjusts the reserve discount factor (RDF) in the market’s physical responsive capability (PRC) calculation on quick-response online generation.

The board unanimously approved staff’s recommendation on the adjustment, pleasing PUC Commissioner Ken Anderson, who has raised concerns over an event last August when the ISO’s scarcity pricing adder, the operating reserve demand curve (ORDC), did not appropriately reflect a reduction in the PRC.

“In defense of ERCOT, these changes are looking to solve the problem we saw last August … the disconnect between the ORDC and PRC,” he said.

On Aug. 13, operators deployed non-spinning reserve service as the PRC dropped to 2,371 MW. However, ERCOT’s real-time online reserve capacity was 3,629 MW, which was reflected in wholesale prices.

ERCOT buys responsive reserve service to ensure sufficient PRC is available. The measure approved by the board aligns the ISO’s systemwide discount factor, lowering it from 2% last year to 1%. It also makes operational adjustments to the RDF.

Board Approves 13 Revision Requests

The board pulled one nodal protocol revision request (NPRR) from the consent agenda but gave it its unanimous approval following a brief discussion.

NPRR758 is designed to provide improved transparency to market participants when transmission outages that could create congestion are submitted with less than 90 days’ notice. It would identify outages that have historically resulted in high congestion costs, as adjusted through stakeholder review to account for upgrades and other changes.

“I’m concerned we don’t have a clear-cut requirement to how we came up with the list and published it,” said Nick Fehrenbach, manager of regulatory affairs and utility franchising for the City of Dallas, before offering up the motion for approval. “We need clear requirements and how we can change them, or we’re leaving ourselves in a quandary.”

TAC Chair Randa Stephenson, of the Lower Colorado River Authority, said the subcommittee and ERCOT staff will “work to ensure a list of high-impact outages is available to public knowledge.”

The board’s consent agenda resulted in the approval of nine more NPRRs, two system change requests (SCRs) and a nodal operating guide revision request (NOGRR).

  • NPRR709: Modifies the alternative-dispute resolution procedure and clarifies parts of the settlement and billing dispute process.
  • NPRR752: Clarifies revision request protocol language to reflect current ERCOT practices.
  • NPRR754: Revises the posting frequency of the load-forecast distribution factors report. Posting is required only when the factors are changed.
  • NPRR761: Clarifies that a resource will not be eligible for make-whole payment startup-cost compensation in the day-ahead market when the market considers the resource as not having a startup cost.
  • NPRR762: Removes references to the provision of responsive reserves across the DC ties.
  • NPRR763: Corrects the formula for calculating qualified scheduling entities’ monthly block load transfer amount to reflect a charge, rather than a payment.
  • NPRR764: Changes calculations for charges to entities short their capacity obligations in reliability unit commitment. Calculations for wind and solar resources will be based on their production potential.
  • NPRR765: Eliminates publisher names for various fuel price indexes and provides additional clarifying language regarding the use of a substitute source for daily fuel prices.
  • NPRR766: Aligns the description of the systemwide discount factor with the proposed operational adjustment to the RDF in the physical responsive capability calculation; also aligns the posting for RDFs applicable to both generation and load resources.
  • SCR788: Updates the formula used to calculate the “generation to be dispatched” (GTBD) value and help minimize GTBD oscillations from one security-constrained economic dispatch interval to the next.
  • SCR790: Adds an additional level of geographical granularity — the Panhandle/North area — to reports on wind power production and forecasts.
  • NOGRR050: Removes ERCOT’s requirement to produce outage-scheduling reports until systems can be changed to include only transmission service providers’ outages.

FERC Clarifies Electronic Quarterly Report Rules

FERC last week clarified its Electric Quarterly Report (EQR) reporting requirements, emphasizing that transmission providers must report transmission-related data (RM01-8, et al.).

The order also updates the EQR Data Dictionary, effective with the report for the fourth quarter of 2016, clarifying reporting requirements and fields related to “Increment Name” and “Commencement Date of Contract Terms.” It also makes changes regarding the “Time Zone” field options and deletes fields for reporting e-Tag data.

Future minor or non-material changes to EQR reporting requirements and the Data Dictionary will be posted directly to the commission’s website, and EQR users will be alerted via email of the changes.

PJM News Briefs from FERC Open Meeting

FERC last week denied a request by PJM’s Independent Market Monitor to clarify or rehear a March order in which the commission found fault with the RTO’s use of the cost-based energy offer cap as the sole measure of short-run marginal cost in calculating capacity market caps (EL14-94, ER16-1291).

At the same time, it accepted PJM’s compliance filing in response to the March ruling. (See FERC Rejects PJM’s Method for Capacity Offer Caps.)

In its request, Monitoring Analytics generally supported FERC’s order but called flawed the use of market-based offers as the measure of short-run marginal costs when they are higher than cost-based offers.

“The Market Monitor contends that the extent to which a market-based offer exceeds a cost-based offer constitutes a markup, and markup is not part of a competitive offer,” the commission said.

“We continue to find that, with limited exceptions, PJM should use, for the purpose of calculating a unit-specific capacity market offer cap, a resource’s non-zero market-based offer to reflect its marginal costs,” FERC ruled. “Simply because a market-based offer exceeds a cost-based offer does not necessarily establish that the market-based offer fails to reflect a resource’s marginal costs.”

The March ruling stemmed from a 2014 FirstEnergy petition that said PJM’s Market Monitor was violating the Tariff by calculating marginal costs using the lower of the market-based offer and cost-based offer.

FERC Denies Rehearing on Order Requiring DR in Capacity Auctions

FERC denied Talen Energy’s request for rehearing of a July 22 order that required PJM to include demand response in its transition auctions for Capacity Performance (ER15-623, EL15-80).

FERC, PJM
Smart Meter Source: CPS Energy

That ruling caused the RTO to delay the transition auctions. (See FERC Orders PJM to Include DR, EE in Transition Auctions.)

The commission also accepted a compliance filing by PJM in response to the July 22 order.

Talen had sought to apply a ruling by the D.C. Circuit Court of Appeals that voided FERC’s jurisdiction over DR in energy markets. However, the Supreme Court later reversed that ruling. (See Supreme Court Upholds FERC Jurisdiction over DR.)

“Accordingly, we dismiss Talen’s rehearing request as moot,” FERC said.

FERC also dismissed an objection by the Advanced Energy Management Alliance Coalition regarding the method PJM proposed to measure and verify DR participation in the transition auctions, saying it was an unrelated issue.

Commissioner Tony Clark concurred in a separate statement.

“I write separately to note my policy and procedural disagreements with the underlying order as fully explained in my separate statement of July 22, 2015,” he said.

Clark dissented from that order, saying it was improper procedurally because the commission had previously approved “unambiguous” Tariff language barring DR and energy efficiency from the auctions.

CAISO to Study Impact of Gas Shortages on Reliability

By Robert Mullin

CAISO transmission planning staff last week proposed studies on the implications of gas shortages on grid reliability.

The planners outlined the studies in a June 13 stakeholder call, saying they will consider the risks to Northern California as well as the more vulnerable southern part of the state.

The disparity between the regions stems from design differences in their pipeline systems and the synergy between Southern California’s storage facilities and its pipeline network.

“Gas storage in the [Los Angeles] Basin is critical [to pipeline operations],” said ISO senior advisor David Le, referring to the gas system’s dependence on the Aliso Canyon storage facility.

Le pointed out that the Aliso Canyon — closed earlier this year because of a gas leak — is vital not only for its massive 86 Bcf storage capacity, but also for its ability to quickly supply large volumes of gas to support pipeline pressure.

Aliso Canyon usually accounts for more than 65% of the inventory held in Southern California’s four major storage sites. The facility also boasts a daily withdrawal capacity of 1.86 Bcf, which helps keep 17 gas-fired generators in the basin supplied with gas under strained conditions.

That withdrawal capability is usually tapped during summer months to help generators meet peak demand. CAISO says that, because of the “magnitude and speed” of the generators’ consumption, pipeline capacity is often insufficient to supply their needs without the ability to backfill from storage such as Aliso Canyon.

CAISO plans to model multiple scenarios stemming from the closure of Aliso Canyon to assess the potential long-term impact of the gas system’s balancing act on Southern California’s grid reliability. Planning staff will develop scenarios in which gas pipeline operators and gas generators lose access to other storage facilities in the region in addition to Aliso.

The study is intended to take a long view, looking at the implications of such gas curtailments to inform transmission planning for 2021 and 2026 as California advances on its 50% renewables mandate.

A parallel study would examine the likelihood for gas curtailments in Northern California, a region with a “much different” gas system, according to Binaya Shrestha, CAISO regional transmission engineer lead.

To provide context for his assertion, Shrestha pointed to the February 2011 gas outages that cut supplies to a number of San Diego-area generators. “Southern California is [subject to] historical outages, but in Northern California, there hasn’t been any curtailment of that level for gas-fired plants,” he said.

That success can be attributed in part to both the line capacity and topology of the gas system.

caiso, gas shortages, reliability
The proximity of gas storage facilities to Northern California’s backbone pipeline provides flexibility for the region’s gas system.

The region’s backbone pipeline — Line 401/402 — has a firm capacity of more than 2 Bcfd. Additional supply arrives via the Mojave gas system originating in the southern part of the state, which serves about 2,200 MW of generation in the ISO’s Pacific Gas and Electric zone.

Furthermore, nearly all of Northern California’s eight major gas storage facilities are distributed along the length of Line 401/402. That arrangement provides operational flexibility because gas can be injected into the system from multiple sites.

Those facilities also equip the region’s gas suppliers with a combined 238 Bcf in inventory capacity — double that in Southern California —  and more than 4.5 Bcf in withdrawal capacity.

Still, the ISO wants to better understand the dynamics of gas supply in Northern California to investigate what chain of events leading to curtailments could compromise the region’s electric reliability.

Stakeholders must submit comments about the gas-electric studies by June 27. Findings will be incorporated into the ISO’s draft transmission plan early next year.

FERC Issues 1st RTO Price Formation Reforms

By Michael Brooks

WASHINGTON — RTOs will be required to align their settlement and dispatch intervals and implement shortage pricing during any shortage period under new price formation rules approved last week by FERC (RM15-24).

FERC Order 825 requires RTOs to settle real-time energy, operating reserves and intertie transactions in the same time interval it dispatches, prices and schedules them, respectively. Although all RTOs currently dispatch resources in five-minute intervals, ISO-NE, MISO and PJM settle those transactions based on the average price for all dispatch intervals during the hour.

This misalignment distorts price signals, as compensation is based on average hourly prices rather than specific periods, including those of greatest need. “These distorted price signals can mute a resource’s financial reward for being able to quickly respond to system needs and create a disincentive for resources to respond to price signals,” Stanley Wolf, of FERC’s Office of Energy Policy and Innovation, said at the commission’s open meeting Thursday.

Operating Reserve Demand (Hogan, Harvard)

Additionally, in some RTOs, an energy or reserve shortage is required to last a minimum amount of time before shortage pricing is triggered. “Due to such delays, short-term prices fail to reflect potential reliability costs, as well as fail to reflect the value of both internal and external market resources responding to a dispatch signal,” Wolf said.

Commissioner Colette Honorable called the order — the first final rule in the commission’s efforts to reform price formation in the organized electricity markets — a “milestone.” The commission began evaluating price formation in 2014 and issued a Notice of Proposed Rulemaking in September. (See NOPR Requires RTOs Switch to 5-Minute Settlements.)

“These requirements will help ensure that rates for energy and operating reserves are just and reasonable and will align prices with resource dispatch instructions and operating needs, provide appropriate incentives for resource performance and maintain reliability,” FERC said.

miso, ferc, price formationThe final order clarifies that the rules would apply to all supply resources, including demand response.

The new requirements take effect 75 days after publication in the Federal Register. Each RTO will be required to make a compliance filing 120 days after that detailing the tariff changes needed to implement the new rules. The order stipulates that FERC will allow an additional year after the compliance filing deadline for the settlement interval changes to go into effect, while it will allow another 120 days for the shortage pricing changes.

“I know that it will take some time and effort for the RTOs to comply with the portion of the rule on settlement intervals; it won’t necessarily be easy,” Commissioner Cheryl LaFleur said. “However, I think it’s critically important that markets send clear, accurate, timely and undiluted price signals.”

House Panel OKs Bill Targeting Clean Line Project

By Tom Kleckner

A U.S. House of Representatives committee last week approved legislation that aims to stop Clean Line Energy Partners’ plans to build a 700-mile HVDC transmission through Oklahoma and Arkansas.

AR Rep Steve Womack (Steve Womack) - congress clean line project
Womack

The House Committee on Natural Resources advanced the Assuring Private Property Rights Over Vast Access to Land (APPROVAL) Act by a 19-11 vote June 15. The bill is sponsored by Rep. Steve Womack, one of the members of an all-Republican Arkansas congressional delegation that is united in opposition to the Clean Line project.

The bill would amend the Energy Policy Act of 2005 to prohibit the secretary of energy and federal power agencies from using eminent domain for transmission rights of way without first receiving approval from a state’s governor and regulatory body. It also restricts the transmission line’s siting to existing federal right of way or land managed by federal entities.

Womack said the bill is “another positive step toward passage in a long and hard-fought battle to allow states to retain the historic precedent of authority for interstate transmission projects.”

“It is our firm belief that the [Energy Department] has overstepped its bounds, and reversing this decision through the passage of the APPROVAL Act remains a top priority,” Womack said, speaking for the rest of his state’s delegation.

Houston-based Clean Line issued an opposing statement, saying that if the bill became law, “it would kill jobs by creating significant barriers to the many businesses in Arkansas … that build American infrastructure, as well as raise electric power costs.”

“Denying American consumers access to the lowest-cost clean energy resources is never good policy,” added Clean Line, which noted more than $100 million in private funds have been invested in the project.

Clean Line’s Plains & Eastern Clean Line is a $2.5 billion, privately funded project that is supposed to deliver 4,000 MW of wind power from the Oklahoma Panhandle through Arkansas to the Mississippi River. The line would interconnect with the Tennessee Valley Authority near Memphis, after first dropping off 500 MW at a converter station in central Arkansas.

Clean Line Project Map Source: Clean Line Energy Partners

Clean Line proposed the project in response to the Energy Department’s 2010 request for proposals for transmission projects under Section 1222 of EPACT 2005, which authorizes the department to participate in “designing, developing, constructing, operating, maintaining or owning” new transmission.

The department approved the project in March, saying it would participate through the Southwestern Power Administration, a federal agency that markets hydroelectric power from 24 dams in six states. (See DOE Agrees to Join Clean Line’s Plains & Eastern Project.)

The Arkansas Sierra Club said it opposes Womack’s bill.

“The Clean Line project has been in the works since 2010 and has undergone a very thorough and expensive public permitting process in accordance with federal law,” said the Sierra Club’s Arkansas director, Glen Hooks. “Rep. Womack’s bill seeks to change that law after the permitting process has been underway for years. That’s not only bad for our state’s air and economy, it’s blatantly unfair to the company.”

Arkansas Sen. John Boozman has filed a matching bill that is co-sponsored by the state’s junior senator, Tom Cotton. The Senate Committee on Energy and Natural Resources held a hearing on the bill in May but has taken no action on it since then.

“Arkansans should be heard in discussions that impact their lands,” Boozman said in a statement released by his office. “Our bill restores the role of states, which in the past had the freedom to approve or reject electric transmission projects. These decisions should not be made behind the closed doors of a federal agency in Washington, D.C.”

MISO Planning Advisory Committee Briefs

MISO has almost finalized its Clean Power Plan analysis after incorporating stakeholder feedback.

Senior Policy Studies Engineer Jordan Bakke said MISO integrated most comments and corrections from five stakeholder groups. The RTO also added an executive summary, reorganized the report for clarity and added explanations on modeling methods and assumptions before sections presenting detailed results.

MISO didn’t accept all stakeholder recommendations, rejecting a request not to take a position on the most inexpensive compliance strategies. The RTO has concluded that a mass-based plan would be less costly than a rate-based plan. (See MISO: Mass-Based CPP Plan 1/3 Cost of Rate-Based.) It said that it “simply laid out … observations and indicated the conditions that are needed for the different compliance implementations.”

“We wanted to stay away from absolute statements on which compliance methods should be used,” Bakke said.

MISO also declined to compare its study with CPP studies by other RTOs, saying the purpose of its study is an independent analysis of its member states.

“As we are not active participants in other studies, a comparison would be best conducted by a third party and should be kept outside the scope of MISO’s report,” the RTO said.

Bakke said MISO and PJM would begin to jointly scope an evaluation of CPP compliance along the MISO-PJM seam in late July.

“We haven’t decided exactly what the study will look like,” Bakke said. “It will be somewhat limited in nature. We want to focus on what is the impact of the two regions coming together” with possibly divergent compliance methods and trading programs.

MISO will finalize the report after reviewing stakeholder input on the executive summary, which is due July 1.

MTEP 17 Futures Process Enters Stakeholder Inspection

MISO is seeking input on a complex approach to the Transmission Expansion Plan 2017 (MTEP 17) futures analysis that relies on stakeholders weighting the probability that particular developments will occur.

MTEP17 Futures Timeline (MISO)

The weightings would reflect RTO staff and member consensus on the relative probability and impact of future economic and policy conditions to assess the cost-effectiveness of different transmission solutions.

MISO is proposing to use a 30% weighting for existing trends, 40% for policy regulations and 30% for accelerated alternative technologies.

Matt Ellis, senior transmission planning engineer, said MISO’s North and South zones will use a single set of weights for the MTEP 17 scope.

He said carbon reduction regulation is the single biggest unknown in the 2017 weighting process, but reductions are likely to advance regardless of policy decision.

“Even with the [CPP] stay, we see our members going forward with compliance plans,” Ellis said. “We see regulations aren’t the ceiling — they’re the floor.”

MISO is asking sector representatives to complete a futures weighting feedback form by June 29.

RTO officials also launched a third and final stakeholder comment period for the MTEP 17 generation siting process, a prediction of where resources will be built that is intended to guide future transmission expansion.

MISO is proposing to prioritize sites associated with generators in the interconnection queue without a signed agreement, existing brownfield sites, and sites for retired and mothballed generation that have not been redeveloped.

Ellis said mothballed sites usually contain infrastructure that can be reused and will be considered before greenfield sites, for which planners have to ask, “‘Is it close to a natural gas pipe? What sort of distance to load does it have?’”

MISO won’t site thermal units in National Ambient Air Quality Standards nonattainment areas in the South region unless nearby coal units retire.

For wind siting, MISO will expand beyond sites provided by the existing Regional Generator Outlet Study (RGOS) because of the possibility that wind additions will surpass renewable portfolio standards. Renewable planning firm Vibrant Clean Energy said that by combining RGOS Zone wind capacity and active and withdrawn wind projects in the queue, MISO could site about 50 GW of new wind projects, with the potential to site an additional 34 GW.

The RTO is also considering adding zonal resource adequacy requirements into MTEP 17 futures to ensure that it meets both local clearing requirements and the current North/South 1,000-MW transfer restriction.

MISO will also site commercial and industrial demand response near the 10 busiest industrial buses and residential DR near the 10 busiest nonindustrial buses in each local balancing area. Distributed generation will be similarly sited by using data from the top 10 load buses in each local balancing area.

The RTO is asking for stakeholders to comment on proposed siting methodology by June 29. It will address the overall MTEP 17 study scope during the July 20 PAC meeting.

Duff-Coleman Proposals due July 6

Proposals for the Duff-Coleman transmission project — MISO’s first competitively bid transmission line — are due July 6. The RTO will select a developer by Dec. 30.

miso planning advisory committee

Brian Pedersen, senior manager of competitive transmission administration, said MISO will accept proposals from qualified developers who have provided a $100,000 deposit.

Weak Auction Prompts Cap-and-Trade Concerns

californiachamber(gov)The state’s cap-and-trade system faces an uncertain future after just 11% of available carbon allowances were sold during last month’s quarterly auction, generating only 2% of expected revenues. Some analysts attribute the surplus of allowances to other state programs that effectively limit utilities’ emissions and their demand for allowances.

Questions also loom about whether cap and trade can continue beyond 2020 without explicit authorization from the state legislature, which last year failed to pass a bill that would have extended the program.

The California Chamber of Commerce continues to challenge the program in court, contending that the allowance system effectively constitutes a tax, which should have been implemented only with a super-majority vote by the legislature.

Regulator Says Utility Cyberattacks Likely

Arthur
House

Arthur H. House, chairman of the Public Utilities Regulatory Authority, told a business group that utilities are likely targets of attacks by computer hackers.

House on Thursday spoke to the Connecticut Business and Industry Association’s conference in Farmington, explaining PURA’s recent cybersecurity report that encourages a cooperative cybersecurity plan between the state and utilities. Part of the plan is to conduct closed-door talks with utilities outside of the regulatory system to maintain security of sensitive information.

“There will be a cyberattack on our utilities,” House said. “The questions are, when will it happen and how we will be able to manage it?”

The D.C. Public Service Commission on Friday unanimously upheld its decision to allow Exelon to purchase Pepco Holdings Inc.

While maintaining her opposition to the merger itself, Chairwoman Betty Ann Kane said the commission acted within the law in approving the deal and that there was no basis for rehearing.

Opponents Public Citizen and D.C. Solar United Neighborhoods, who had asked for a rehearing, said they will take their appeal to court. Meanwhile, D.C. People’s Counsel Sandra Mattavous-Frye said her office is reviewing the decision before deciding whether to challenge it. (See District, OPC Ask PSC to Reconsider Exelon-PHI Merger.)

Court Rejects Net Metering Extension to Community Solar

comed(comed)A state court of appeals ruled that Commonwealth Edison isn’t required to extend net metering rates to community solar projects in a defeat for a consumer protection group and the Environmental Defense Fund.

The Citizens Utility Board and the EDF had requested the Commerce Commission apply net metering rates to customers who signed on to community solar projects. ComEd opposed the request, and the ICC agreed, saying the Public Utilities Act prohibits the commission from issuing such a mandate. On appeal, the 1st District Appellate Court upheld the commission’s dismissal.

“The commission is an administrative agency responsible for setting utility rates, whose powers and duties are set forth in the act,” the court wrote. “Consequently, we give substantial deference to the commission’s decisions in light of its expertise in the area of utility ratemaking.”

Proposed Entergy Plant Draws Backlash from Neighbors

Entergy’s proposal to build a new generation unit at a brownfield site in Eastern New Orleans is drawing heated opposition even before any formal plans have been filed. Nearly 50 community leaders, consumer advocates and environmental activists gathered June 15 at a New Orleans City Council public hearing to speak against the new natural gas-fired plant.

Entergy New Orleans has not officially asked the council to approve its plans, but earlier this year it identified the new unit as a key investment in its long-term power generation plan. The company shuttered the aging 918-MW Michoud power plant earlier this year and hopes to build a fast-starting 250-MW combustion turbine at the site. A formal filing is expected soon.

New Orleans East residents are concerned the plant would pollute their neighborhoods and contribute to sinking land. Opponents also argue Entergy is not making a big enough effort to embrace energy efficiency and renewable sources in its planning.

Lawmakers Consider Renewable Energy ‘Goals,’ not Mandates

DTESteveKurmas(dte)
Kurmas

The House and Senate energy committees are proposing new renewable energy goals, rather than a new renewable portfolio standard, even as the state’s two major utilities say they would support new mandates.

A Senate bill would set a 35% renewable goal by 2025, while House legislation includes a 30% goal by 2025. Neither plan includes penalties if the targets aren’t met. The current RPS mandates 10% renewables by 2015.

While some lawmakers are opposed to renewable mandates, large utilities say they would comply. Steve Kurmas, vice chairman of DTE Energy, said the utility “will build incremental renewables with or without a mandate.” David Mengebier, senior vice president of governmental and public affairs for Consumers Energy, said the company would be “OK” with mandates.

Regulators Approve Coal Plant Retirements

TaconiteHarbor(minnpower)Minnesota Power said it will study the implications of reducing its coal reliance after the Public Utilities Commission approved the utility’s 15-year resource plan, which calls for more investments in wind, solar and natural gas and the retirement of coal units at two plants.

Under the plan, the Taconite Harbor plant in Schroeder would discontinue coal use by 2020, and two coal-fired units at the Clay Boswell plant in Cohasset would shut down in 2022.

The PUC asked that the Duluth-based utility study its changing resource mix. Minnesota Power, which now relies upon coal for 75% of its power, plans to transition to equal one-third parts coal, renewables and natural gas. A decade ago, Minnesota Power’s portfolio was 95% coal.

City Utility, KCP&L Reach Settlement over Tx Usage

KansasCityP&L(kcpl)Kansas City Power and Light will pay the City of Independence’s utility nearly $12 million in installments during the next four years to settle a disagreement over transmission costs.

The case stems from Independence Power and Light’s decision to change its status with SPP from non-transmission owner to transmission owner last year. That meant new rates whenever SPP used IPL’s transmission system.  Independence had billed KCP&L for an annual transmission revenue requirement of $7.2 million, and KCP&L objected to the higher rate.

The settlement requires FERC approval.

NorthWestern Asks PSC to Halve Mandated Solar Rates

northwesternenergy(northwestern)NorthWestern Energy asked the Public Service Commission to cut the amount it is mandated to pay to commercial solar projects of 3 MW or less. The utility told the PSC that the mandated price to qualified facilities is too high and is hurting consumers.

NorthWestern wants the current rate cut in half and the contracts shortened. The state’s rate is $66/MWh, similar to the price the company gets for its own hydroelectric power.

The solar projects are each capable of powering about 540 homes, and there are more than 80 on the current docket, NorthWestern said. “For each 3-MW project, the differential between the QF rate and the rate we propose is about $5 million per solar contract,” said John Alke, a NorthWestern attorney. The contracts run 25 years.

Court Allows Colstrip Lawsuit to Continue

colstripplant(pugetsoundenergy)A state judge expressed alarm last week at the estimated 200 million gallons of contaminated water seeping annually from leaky ash-storage ponds at the Coltstrip power plant and allowed a lawsuit challenging the state’s enforcement efforts to proceed.

District Judge Robert Deschamps rejected arguments from Department of Environmental Quality officials that they were appropriately managing the problem. A 2012 deal between regulators and Talen Energy, Colstrip’s manager, was intended to clean up decades of contamination of underground drinking water supplies. Under a separate settlement, the plant’s six owners paid $25 million to Colstrip residents whose water was fouled by the plant’s ash ponds.

Environmentalist groups are challenging the 2012 agreement, which set few deadlines for action and could entail years of further study.

NEW HAMPSHIRE

Cooperative First to Buy from Wind Farm

newhampshirecoop(newhampshire)The New Hampshire Electric Cooperative is the first buyer of power produced by the Antrim Wind project. The cooperative will purchase 25% of the $65 million project’s output, or about 7.2 MW.

The 20-year agreement represents about 3% of the cooperative’s total demand. The 5.4 cents/kWh its customers pay for generation is among the state’s lowest. The cooperative said the power will help it meet its mandate under the state’s renewable portfolio standard and its own goal of having 25% of its demand served by renewable energy by 2025.

Construction is to begin later this year with operations starting by the end of 2017.

RG&E, NYSE&G Rate Hikes Approved

rochestergas(rg&e)Regulators approved the first rate increases in four years for Rochester Gas & Electric and New York State Electric and Gas customers. The increases are effective July 1 and will be phased in over two years.

A typical RG&E electricity customer would pay $1.10 more per month beginning in July, another $2.39/month a year after and a third increase of $2.84/month in July 2018. NYSEG customers would see monthly increases totaling $5.75/month by July 2018.

Part of RG&E’s increase would help pay for the Ginna Retirement Transmission Alternative that is intended to mitigate the possible closure of the Ginna nuclear power plant. RG&E electric customers already are paying a $2.20/month surcharge to keep Ginna operating until March to maintain system reliability.

Bill Would Block PSEG-LI Power Purchases

psegli(pseg)Two state legislators introduced a bill last week that would force PSEG-Long Island to separate electricity purchasing planning from system management to reduce what the lawmakers believe is a conflict of interest.

Assembly members Fred Thiele Jr. and Dean Murray introduced legislation to separate the functions, saying that PSEG-LI may face conflicts of interest because it produces power from its own units. The utility has recommended that the Long Island Power Authority not buy power from a planned 750-MW Caithness power plant, which it said is not needed.

PSEG-LI took over managing the electric grid on Long Island from the Long Island Power Authority last January. It was also instructed to develop plans to purchase power.

PSC Approves Brady I Wind Farm; Brady II Next?

northdakotawind(wiki)The Public Service Commission last week unanimously approved the contentious $250 million, 87-turbine Brady Wind Energy Center I. The NextEra Energy Resources project will provide 150 MW of power for Basin Electric Power Cooperative.

The project faced stiff opposition and went through the longest hearing for a proposed wind farm in state history, with 15 hours of testimony on March 31. The PSC also consented to construction of a 19-mile transmission line.

NextEra expects construction to begin this month, with the project scheduled to be completed by the end of the year. The project is part of a proposed two-phase wind complex in the state’s southwest. The PSC is still considering the application for the adjoining 150-MW Brady Wind II project, which calls for 72 turbines.

Gov. Peter Shumlin signed a renewable energy bill that gives “substantial deference” to towns where renewable projects would be located.

The legislation was based in large part on the recommendations of the Solar Siting Task Force to give localities more say in the Public Service Board permitting process for projects that have been determined to meet the state’s energy and climate goals.

The General Assembly passed the bill on June 9 after a previous version of energy siting legislation was vetoed by Shumlin over concerns of the unintended effects of new wind sound standards.

Dominion Plan to Bury Power Lines Met with Skepticism

virginiadominion(dominion)The State Corporation Commission questioned Dominion Virginia Power’s request for a $140 million proposal to bury its most vulnerable power lines to decrease outages.

The project, which would put about 400 miles of distribution lines underground during the first phase, would increase customers’ bills by about $6/year. Commissioners questioned whether the same result could be achieved through other, less expensive efforts, such as tree trimming.

The utility originally asked state regulators to approve a $263 million plan. The commission is expected to rule in the next few weeks.

CAISO News Briefs from FERC Open Meeting

FERC last week granted PacifiCorp’s request to suspend the relicensing proceeding for the 169-MW Klamath Hydroelectric Project in order to give the utility more time to transfer the facility to new owners ahead of the removal of four dams (Project No. 2082-027).

The fate of the project — which straddles the California-Oregon border along the Klamath River — became the subject of negotiations among state and federal agencies, Native American tribes, environmental groups and local farmers in 2008. Two years later, PacifiCorp reached a settlement agreement to remove four of the project’s dams, contingent on passage of federal legislation authorizing the removal.

Congressional inaction triggered dispute resolution proceedings early this year, resulting in PacifiCorp agreeing to transfer the project’s license to a new entity — the Klamath River Renewal Corp. — in July. That entity is expected to immediately file with FERC to surrender and remove the dams under the commission’s process, rather than await approval from Congress.

“Requiring the parties, other stakeholders and commission staff to simultaneously proceed with both a relicensing proceeding and a transfer and surrender proceeding would be burdensome and an inefficient use of resources,” the commission said in its ruling.

FERC OKs NextEra Tariff Revisions Covering CAISO Competitive Projects

FERC last week accepted a NextEra Energy compliance filing revising a tariff for two transmission projects the company has been awarded through CAISO’s competitive selection process (ER15-2239-002).

The commission agreed with NextEra’s explanation that the tariff’s formula rate would only apply a 150-basis-point adder to an initial assessment of the long-term cost of debt for the projects — a figure based on the company’s debt cost for a Texas project. The adder, the company clarified, would be recalculated once long-term debt is actually issued.

The commission also rejected a request by the California State Water Project that NextEra’s tariff clarify the term “third-party debt,” ruling that the argument was outside the scope of the proceeding.

“The commission has repeatedly held that compliance filings are limited to the specific directives of the commission’s order,” the commission wrote. “The sole issue on review is whether the filing party has complied with those directives.”
