NV Energy files to be in California ISO energy imbalance market

NV Energy filed a request today with the Public Utilities Commission of Nevada (PUCN) seeking approval to participate in the California Independent System Operator Corporation’s (California ISO) energy imbalance market. Meanwhile, the California grid operator separately is asking the Federal Energy Regulatory Commission (FERC) to approve the Implementation Agreement with NV Energy.


The energy imbalance market is a voluntary, five-minute balancing market that provides participants the opportunity to more efficiently manage existing energy resources. Participants in the EIM can use power generation resources across the entire western-wide EIM region, with the added benefit of more frequent power plant dispatching in real time to better optimize available energy supplies with actual energy demand.

Study results show that NV Energy participation will provide direct economic benefits to NV Energy customers as well as increase the total EIM benefits to ISO and PacifiCorp customers. In addition to the economic benefits, the EIM is expected to produce important system reliability benefits.

To realize these benefits, NV Energy, which serves 1.3 million customers throughout Nevada and nearly 40 million tourists annually, is requesting PUCN approval to participate in the EIM starting in October 2015.

The ISO has already taken steps with its first EIM partner, Portland-based PacifiCorp, to make changes to the ISO’s existing real-time market to accommodate non-ISO entities. PacifiCorp’s participation in the EIM is scheduled to start in October 2014.
