Three BANC members and WAPA’s Sierra Nevada division jointly announced they intend to join CAISO's Western Energy Imbalance Market.

An analysis by Eastern RTOs and utilities has found no advantages to changing how they measure primary frequency response.

SMUD said it is canceling a 500-kV transmission line project it was developing with WAPA because it had proven too expensive and was no longer needed.

WAPA said its Sierra Nevada region will go with CAISO for RC services, while its Rocky Mountain and Desert Southwest regions will go with SPP.

The SPP Regional Entity’s Board of Trustees officially terminated the RE’s regional delegation agreement, effective 5 p.m. CT on Aug. 31.

WAPA said it has submitted a formal request to SPP for reliability coordinator services on behalf of two of its balancing authorities.

WAPA has selected a route for the TransWest Express transmission project, an HVDC line proposed by Anschutz Corp.

Meeting the California RPS goal of 50% target could require more than $5 billion in transmission upgrades, according to a state report.

The Sacramento Municipal Utilities District (SMUD) will join the Western EIM in spring 2019 at the earliest, according to the head of BANC.

A parallel effort to create an organized electricity market (RTO) is taking shape in the inland West even as CAISO attempts to expand.
