Resource Adequacy
Resource adequacy is the ability of electric grid operators to supply enough electricity at the right locations, using current capacity and reserves, to meet demand. It is expressed as the probability of an outage due to insufficient capacity.
Dynegy and Exelon proposed that MISO Zone 4 procure capacity in three-year forward auctions separate from the rest of the RTO.
Reducing SPP’s current 13.6% reserve margin to 12% could cut required capacity by about 1,000 MW, saving $86 million annually and $1.3 billion over 40 years.
The MISO System Planning Committee reviewed the RTO's 2015 Transmission Expansion Plan and resource adequacy.
ERCOT's seasonal assessments of resource adequacy for the fall and winter predict enough generation available to serve forecasted peaks.
MISO officials outlined proposals to boost its capacity resources, winning support for efforts to streamline the generator interconnection process and redraw its zonal boundaries to reflect constraints.
MISO no longer faces a capacity shortfall next year, the RTO announced today in releasing the results of its newest survey with the Organization of MISO States.
MISO launched the first in a series of stakeholder workshops dedicated to improving resource adequacy as the RTO deals with the retirement of coal-fired generation and the growth of natural gas and renewables.
MISO stakeholders indicated widespread support for moving to a seasonal measurement of resource adequacy; supporters say it would improve reliability.
