The CAISO-run Western EIM has increased the operational flexibility of the region’s utilities, panelists said at the Infocast Transmission Summit West.

Berkshire Hathaway Energy subsidiaries PacifiCorp and NV Energy asked FERC to lift bidding restrictions placed on them in the EIM.

CAISO hauled in the largest share of the $39.52 million in benefits produced by the EIM during the second quarter.

Energy transfer capacity in the EIM footprint is now sufficient to justify removing bid limits that are in effect for some members, the CAISO Monitor says.

Members of the Energy Imbalance Market (EIM) saw increased savings and profits with the addition of Puget Sound Energy and APS.

FERC denied the Berkshire Hathaway Energy request to rehear a ruling prohibiting the company’s subsidiaries from selling electricity at market-based rates.

Increased transfer capacity is keeping a lid on congestion in the EIM and limiting participants’ ability to wield market power, according to CAISO’s IMM.

PacifiCorp reaped well more than half the $26.16 million in gross benefits yielded by the Energy Imbalance Market (EIM) in the third quarter, CAISO said.

Last week's FERC technical conference on the EIM began on a contentious note but concluded with participants understanding each others’ perspectives.

Berkshire Hathaway Energy affiliates NV Energy and PacifiCorp refunded nearly $95K to customers after FERC revoked their market-based rate authority.
