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

The design framework for a California Independent System Operator (ISO) energy imbalance market (EIM) received approval from the ISO board of governors. The EIM will allow western grid operators, known as “balancing authorities”, to voluntarily participate in a real-time energy market that enhances grid reliability and responsiveness, effectively integrates renewable power and saves wholesale energy costs. The ISO’s first EIM partner, PacifiCorp, has been working with the ISO to prepare for implementing the market expected to go live on October 1, 2014.
The Federal Energy Regulatory Commission (FERC) approved the implementation agreement between the California Independent System Operator (ISO) and PacifiCorp that establishes the scope and schedule for a variety of tasks the parties will undertake to launch an energy imbalance market (EIM) by October 2014. 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.

PacifiCorp and the California Independent System Operator Corporation (CAISO) entered a memorandum of understanding that commits the two largest grid operators in the western United States to work toward creating a real-time energy imbalance market (EIM) by October 2014. If implemented, PacifiCorp – which controls two balancing authorities primarily covering portions of six states, including part of Northern California – would participate in a co-optimized real-time energy market facilitated by the ISO. The joint agreement applies only to the EIM service.
