Although PacifiCorp formally committed to joining CAISO’s Extended Day-Ahead Market, the utility is still voicing concerns about a competing day-ahead market, SPP’s Markets+, in a FERC filing.
Two competing day-ahead markets from CAISO and SPP are taking different approaches to resource sufficiency and adequacy, according to presenters at a workshop included in a regulatory effort to help inform NV Energy’s decision on which market to join.
A key factor in the CAISO EDAM advantage is the benefits the utility would lose by leaving the Western Energy Imbalance Market, a Brattle Group consultant said.
Nevada regulators approved NV Energy’s plan to convert its last coal-fired power plant to natural gas, while also allowing the company to move forward with a $1.5 billion, 400-MW solar-plus-storage project.
NV Energy is aiming to bring a proposal to Nevada regulators by the end of the year for joining a day-ahead market, but what process regulators will use to evaluate that request is still very much up in the air.
NV Energy would gain significantly more economic benefits from participating in CAISO’s EDAM than SPP’s Markets+, new analysis from the Brattle Group shows.
NV Energy and several stakeholder groups have weighed in on how Nevada regulators should evaluate a request from the utility to join a day-ahead market or RTO.
CAISO is moving quickly to gain approval for a proposed transmission line that would allow California to meet targets for tapping Idaho wind resources while helping both states bolster their resource adequacy.
FERC approved a raft of CAISO tariff changes intended to ease temporary restrictions on wheeling power through the ISO’s grid under emergency conditions.
