FERC Approves Implementation for ISO-PacifiCorp Energy Imbalance Market

ISO also issues revised Market Design Proposal

FOLSOM, Calif.--()--The Federal Energy Regulatory Commission (FERC) has approved the implementation agreement between the California Independent System Operator Corporation (ISO) and PacifiCorp that establishes the scope and schedule for a variety of tasks the parties will undertake to launch an energy imbalance market by October 2014.

“We find that the Implementation Agreement is just, reasonable, and not unduly discriminatory or preferential. Accordingly, we will accept the Implementation Agreement, effective July 1, 2013, as requested,” FERC said in the ruling. See the complete ruling here.

Among its provisions, the implementation agreement sets out procedures for PacifiCorp to pay the ISO a $2.1 million fixed start-up fee to enable PacifiCorp to participate in the ISO’s existing energy imbalance market. The implementation agreement was filed with FERC on April, 30, 2013.

Revised market design released

The ISO also issued yesterday July 2, 2013 a revised “straw proposal” that sets forth the proposed structure and rules for operation of the energy imbalance market. The market design reflects changes made in response to stakeholder feedback regarding earlier versions. Among the changes are extensions to the time external parties will have to review and offer comments to the market design rules before they are finalized and submitted to the ISO Board of Governors to consider in November.

The revised market design proposal and adjustment to the stakeholder process does not affect the planned October 2014 “go-live” date for the EIM. See the revised market design proposal here.

The ISO and PacifiCorp announced a partnership in February 2013 to add PacifiCorp’s two balancing authorities covering portions of six western states to the existing EIM operated by the ISO in California. The EIM is intended to reduce operational expenses for both parties through more efficient dispatch of resources within and between balancing authorities, the ability to share and therefore reduce the need to hold flexibility reserves, and reduced curtailment of renewable generation sources.
