Project developers responded to NV Energy Inc.'s request for proposals with more than 100 renewable energy project proposals, including more than 30 bids offering battery storage.
The Berkshire Hathaway Energy subsidiary issued a solicitation Jan. 9 to add up to 330 MW of renewable energy projects in Nevada. Bidders responded with proposals for wind, geothermal, solar, biomass and battery storage projects at 26 locations. NV Energy said this is the first time it has included battery storage systems in a solicitation. The utility's solicitation specified that supplemental battery energy storage systems of at least 25 MW each could be proposed in addition to renewable energy projects.
The company said it wants to double capacity in its renewable energy portfolio by 2023 without raising customer rates. NV Energy said an independent evaluator will oversee the selection of projects. The utility expects to select a short list of bidders by early March, execute contracts May 14 and submit them to the Public Utilities Commission of Nevada on June 1 for approval by the end of this year.
Specifications require the new projects to be completed and producing energy for customers by 2021. NV Energy's Senior Vice President of Renewable Resources Dave Ulozas said renewable projects and the potential addition of battery storage will help protect customers from the risk of increases in the price of natural gas used to generate electricity.
The solicitation requested proposals for projects ranging from 35 MW up to 330 MW with the option of supplemental battery storage systems that could deliver at least 25 MW of output for four hours for a total of 100 MWh.
The request for proposals called for projects in the service areas of NV Energy subsidiaries Nevada Power Co. in southern Nevada and Sierra Pacific Power Co. in northern Nevada.
