The California Independent System Operator Corp. (California ISO) filed a request with the Federal Energy Regulatory Commission (FERC) to approve an implementation agreement reached with PacifiCorp that outlines how the ISO's energy market could be expanded to provide real-time services to the utility. Concurrently, the ISO is holding a stakeholder initiative to design the imbalance market and establish its rules.
The energy sharing market would optimize power supplies by providing frequent, automatic and efficient resource dispatching across a larger region, according to California ISO. PacifiCorp serves customers in six western states and joined with the ISO in a study that quantifies the benefits to both ISO and PacifiCorp customers ranging from $21 million to $129 million by 2017.
Additional independent studies by the National Renewable Energy Laboratory (NREL) and FERC also established the benefits of an energy imbalance market. The NREL study is called Examination of Potential Benefits of an Energy Imbalance Market in the Western Interconnection (March 2013) and the FERC study.
In its filing April 30, 2013, the ISO asks that the implementation agreement take effect without delay to help pave the way for PacifiCorp to begin using the market in 2014. Additional interested balancing authorities could access the real-time services as early as 2015.
