NV Energy intends to join the Extended Day-Ahead Market (EDAM) launched by the California Independent System Operator (ISO), as disclosed in the utility’s filing of its triennial integrated resource plan to the Public Utilities Commission of Nevada.
NV Energy expects to expand on its cost savings already realized through its participation in the ISO’s real-time Western Energy Imbalance Market (WEIM) by joining the EDAM.
The growing EDAM footprint is responsible for NV Energy’s decision. The anticipated participation by the ISO, PacifiCorp, Balancing Authority of Northern California, Los Angeles Department of Water and Power, and Portland General Electric, will provide valuable interconnectivity and support access to a diversity of resources.
Additionally, Idaho Power has indicated interest in EDAM as its preferred day-ahead market.
"Participating in the EDAM allows NV Energy to better plan resource needs and fully optimize its generation portfolio, reducing costs for our customers,” said NV Energy President and CEO, Doug Cannon. “We look forward to continuing this work with the ISO to grow the footprint even more and drive better outcomes for all."
The WEIM has produced $5.5 billion in economic efficiencies and enhanced reliability by leveraging transmission connectivity and resource diversity across a broad geographical footprint covering 22 entities in 11 states. EDAM, scheduled to launch in 2026, is predicted to build on WEIM’s success by expanding into the day-ahead market.
NV Energy’s intention to join the EDAM is expected to boost the efficient coordination of the electric requirements for growing loads and a changing resource mix across the West.
NV Energy supports the ongoing work of the West-Wide Governance Pathway's Initiative and looks forward to the ISO implementing governance changes to facilitate the utility’s participation in the EDAM and ensuring participants outside California are willing to improve the future market operations for the benefit of customers.
By the end of 2024, NV Energy will follow up with a formal filing to its state commission looking for approval to join EDAM.
