SPP Board Approves Alternative, Accelerated Generation Interconnection Process to Improve Regional Resource Adequacy

LCG, May 8, 2025--The Southwest Power Pool (SPP) Board of Directors approved SPP’s proposed Expedited Resource Adequacy Study (ERAS) at its May 6 meeting. SPP developed the new ERAS in collaboration with its stakeholders in response to the growing need to add new generating resources before the region’s generating capacity is outpaced by its electricity demands. ERAS is intended to be a one-time, expedited study process designed to significantly accelerate the addition of new power generation facilities to the grid and address concerns about the near term ability to maintain the affordable and reliable electric service that consumers expect.

New England ISO's Market Design Approved by FERC

LCG, Sep. 30, 2002--ISO New England's market design proposal, reflecting elements similar to those in the market run by PJM Interconnection, the mid-Atlantic grid operator, was largely approved by the Federal Energy Regulatory Commission last week.

The most important features of the proposal include "designated congestion areas," where known supply problems exist; a transition to locational marginal pricing within 18 months, in order to reflect the spatial variation in supply and demand; a system to auction financial transmission rights, by which owners of rights can earn revenue; and a demand management program to pay customers to reduce demand. The one area over which dissent was expressed was the level of installed capacity payments, which Commissioner Nora Brownell thought insufficient to draw long-term investment.

Although ISO New England and the New York Independent System Operator have discussed a merger between their market operations, some New England states have resisted, fearing that power supply would flow to New York. FERC commented that although upcoming market rules it will finalize in 2004 could lead to necessary changes in market rules, the current proposal "benefits customers by accepting improvements to New England's markets, including a day-ahead and real-time market, locational marginal pricing, mechanisms to mitigate market power, demand response programs, and a capacity resource mechanism."
