Utah lawmakers plan to draft a bill requiring PacifiCorp to gain legislative approval before joining an RTO based on an expanded CAISO.
Members of the Public Utilities, Energy, and Technology Interim Committee approved a motion to create the proposed law July 13 after listening to more than 90 minutes of testimony from power industry participants — most of whom were wary about the state’s participation in a regional integration effort driven by California.
Specific terms of the legislation were left unclear.
Utah sits squarely inside the PacifiCorp East (PACE) balancing authority area, which also extends into portions of Idaho and Wyoming. It is served by PacifiCorp’s Salt Lake City-based Rocky Mountain Power subsidiary.
“This potential issue is significant from both a policy perspective and a financial perspective,” said Thad LeVar, chair of the Utah Public Service Commission.
LeVar noted that PacifiCorp must go before his agency for a ruling once it makes a determination to join an expanded regional grid. The decision “shouldn’t fall solely to the regulatory arena without some guidance from the legislators in the state,” he said.
Governor Skeptical
Laura Nelson, director of Gov. Gary Herbert’s Office of Energy Development, said the office was skeptical about an RTO but still engaged in the process related to its development.
“Our consistent message has been that any participation in the [CAISO] must protect Utah’s long-term interest and authority over its power system,” Nelson said, citing the state’s role in protecting ratepayers, maintaining system reliability and choosing the generating resource mix.
Nelson told the committee that the state needs to perform an “exhaustive” study to determine if PacifiCorp’s membership is in the best interest of ratepayers. “Any recommendations about joining CAISO are not yet fully informed,” she said.
Ratepayer protections were foremost among the concerns of Michele Beck, director of the state’s Office of Consumer Services. While Beck acknowledged that there are technical benefits to participating in a more centrally operated grid, she questioned who would enjoy them.
“Do the benefits accrue to customers, or will they accrue to just select elements within the industry?” she said. “Are the benefits reasonably distributed across the footprint? Are the modeled benefits durable?”
She said that membership in an expanded CAISO should be conditioned on a demonstration that it has greater benefits than the Western Energy Imbalance Market, in which PacifiCorp currently participates.
“We’re struggling to document that all the benefits of the EIM that have been stated and have been published have been realized,” Nelson said.
Chris Parker, director of Utah’s Division of Public Utilities, said he was concerned about risks as well as benefits — namely the state’s risk in giving up control over its utilities to an RTO, whose backstop authority would be FERC.
Fear of California Dominance
Parker also cited the risk of an RTO being dominated by California interests, saying his agency would seek assurances that policy changes would require the unanimous support of participating states. He said CAISO’s latest RTO governance proposal — which would initially provide California with numerical voting superiority — was unacceptable.

Rocky Mountain Power CEO Cindy Crane called the development of an independent governing structure a “threshold” issue for her company in its decision to participate in an expanded CAISO.
“What we are not doing is joining the California ISO,” Crane said. “We are working to transform an existing operating entity into something that could be a regional operating entity.”
Crane said the requirement that an RTO deliver “risk-balanced” net benefits to PacifiCorp customers in each of its six states was a second condition for the utility.
“If it’s not going to deliver benefits for our customers, there is no reason for us to advance,” she said, adding that regulators in each PacifiCorp state will have the authority to decide whether the utility joins.
Watching California’s Legislature
A few witnesses testifying before the committee said the fate of a Western RTO is now in the hands of California lawmakers, which are slated to begin considering legislation in August that would loosen the state’s authority over CAISO.
“We’re at the point where we’re waiting to see what the California legislature is willing to give up,” said Parker, referring to the concerns about California’s dominance in a governing structure. “If they’re willing to give up enough, then it may be worth it.”
OG&E sued FERC in December 2014, arguing that when it agreed to join SPP, it gave up some transmission planning rights in return for the right of first refusal. The utility said FERC couldn’t meet a higher legal burden to negate that part of the membership agreement, which predated Order 1000.

The proposed project would use the existing 12-foot-high dam and create a 1,000-acre impoundment area, with new intakes, a new tailrace and four 2-MW turbines, along with a new powerhouse and substation.

The House passed a $32.1 billion funding bill for the Interior Department and EPA, about $1 billion less than what the Obama administration requested, and a $64 million cut over current spending levels. The bill includes a number of riders intended to block EPA water, power plant and coal mining regulations.
A report by Bloomberg New Energy Finance shows that renewable energy funding has fallen 23% for the first six months of the year compared to last year. It said investments globally were about $116.4 billion for the first half of the year. Second-quarter investments were $61.5 billion, 12% higher than the first quarter, but still 32% lower than the $90 billion for the same period last year.

The plan’s aim is to reduce peak load on the utility’s distribution system and includes programs to encourage the use of smart thermostats, demand response, LED lighting and technologies that improve the efficiency of air conditioners.

The Utilities Commission says two nonprofits must put up a $98 million bond to go forward with an appeal of a permit given for a new Duke Energy gas-fired power plant. The commission originally set the bond at $10 million, but an appellate court told it to recalculate the bond based on “competent evidence.”

Adam Bell, SPP’s interregional coordinator, told the committee July 8 that the two RTOs have not nailed down the scope, but that it may not be limited to the Dakotas’ seam with the Western Area Power Administration, as MISO would prefer. The two grid operators agreed May 31 to take a “targeted” look at the newly created seam. (See “SPP, MISO Agree to Conduct ‘Targeted’ Joint Tx Study,”
