CAISO and PacifiCorp reaped the majority of the Western Energy Imbalance Market’s $42.1 million in gross benefits during the first quarter (Q1 2018).

Western Energy Imbalance Market (EIM) leaders on Tuesday approved rule changes that would allow EIM balancing areas to manually adjust load forecasts during market operations to ensure the grid can support system conditions.

CAISO provided details on its plans for major changes to improve the alignment of its day-ahead market with real-time demand.

Idaho Power and Powerex began transacting in the EIM, bringing to eight the number of members participating in CAISO’s regional real-time market.

The Colorado Public Utilities Commission held its fifth public information session on the potential addition of the Mountain West Transmission Group to SPP.

CAISO's Extended Day-Ahead Market proposal could be done without the political entanglements involved with an RTO, Sarah Edmonds said.

Westerners still hold some “anxiety” and “hesitancy” about a new RTO in the region, says EIM Governing Body Chair Doug Howe.

Western Energy Imbalance Market leaders endorsed CAISO’s controversial proposal to give generators more bidding flexibility.

FERC approved a package of modifications developed by CAISO for the EIM, and issued several other decisions related to Western states and energy markets.

The Energy Imbalance Market Governing Body rejected the CAISO move to change how members of the panel are nominated.
