Dive Brief:
The Nevada Public Utilities Commission recently approved a plan for NV Energy’s utilities, namely Nevada Power and Sierra Pacific Power, to join the Extended Day-Ahead Market (EDAM) formed by the California Independent System Operator (CAISO). This decision will be effective in the fall of 2028, allowing NV Energy to tap into a wider energy network and enhance participation from distributed energy resources in the wholesale market.
The commission noted CAISO’s adaptive governance and quick response capabilities in emergency situations as essential factors in their approval.
Dive Insight:
Two day-ahead markets are currently emerging in the West: EDAM and the Southwest Power Pool’s Markets+. EDAM is set to launch on May 1, with several participants, including PacifiCorp, Portland General Electric, and others expected to join in the upcoming years.
NV Energy will play a significant role in this market, boasting about 6.6 GW in utility ownership and sourcing around 3.7 GW of its renewable energy from solar through power purchase agreements. Additionally, there are plans for 1.4 GW of future renewable sources as noted in Berkshire Hathaway Energy’s latest report.
NV Energy is also investing in key transmission assets connecting it to neighboring regions, as well as developing the $4.2 billion Greenlink project, which will be fully operational by 2029.
The commission emphasized the operational efficiency and policy benefits that EDAM can provide, given its diverse range of energy resources. NV Energy anticipates annual savings of $93.1 million from joining EDAM, primarily due to reduced production costs and increased revenue from market activities.
Joining EDAM will facilitate compliance with the Federal Energy Regulatory Commission’s Order 2222, which seeks to include more distributed energy resources in wholesale markets.
Support from companies like Google, which aims to leverage the diverse energy mix available through EDAM, highlights the broader benefits of this market for efficient energy management. Google indicated that accessing energy from various regions could enhance NV Energy’s operational flexibility.
Experts believe that NV Energy’s involvement in EDAM will not only improve local energy operations but also strengthen the Western grid, enabling better resource sharing across states and ultimately driving down costs.
