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.
The Markets and Reliability Committee endorsed PJM's recommended installed reserve margin and forecast pool requirement values for the 2026/27 Base Residual Auction.
A study of SPP’s future energy and resource needs has found the grid operator will have to rely on thermal generation to maintain grid reliability into midcentury, but it will come at a cost.
While NYISO operated reliably last winter, the season provided “continued examples of limited flexibility on the gas system,” ISO staff told the Operating Committee.
FERC accepted SPP’s proposed tariff revisions to incorporate a mark-to-auction collateral requirement for its transmission congestion rights market but did not terminate a show-cause proceeding.
PJM’s Markets and Reliability Committee endorsed two proposals to revise the RTO’s ELCC formula to add two new generation categories and limit the penalties resources face if their accreditation declines between auctions.
FERC's State of the Markets report showed lower wholesale energy prices but growing demand and higher capacity prices that signal a need to meet the coming load.
CERAWeek 2025 by S&P Global examined the changing energy landscape through 14 themes, from policy and regulation to climate and sustainability, but none seemed to draw more focus than the rapid expansion of AI and is potential transformative effects.
FERC is expected to rule on SPP’s proposed tariff revisions adding a winter season resource adequacy requirement and several other issues related to the grid operator.
ERCOT already operates a power system as large as those in several European countries, but demand growth is expected to bring it up to the level of PJM and MISO, which has the industry considering building a new system of 765-kV lines to transmit power around Texas.
MISO members haven’t landed on easy answers in getting the approximately 54 GW of unfinished generation that has cleared the interconnection queue online sooner.
