EDF Renewables plans to construct a 200-megawatt photo voltaic plant with a 180-megawatt/720-megawatt-hour battery for Nevada utility NV Power, the developer introduced Wednesday, including to the rising checklist of enormous solar-and-storage initiatives beneath development inside the state and area.   

Even at that measurement, the undertaking will solely barely skate onto the checklist of the 10 largest batteries within the U.S., primarily based on monitoring of confirmed undertaking particulars from Wooden Mackenzie. This month NV Power filed a proposal with state regulators so as to add 478 megawatts of recent photo voltaic and 338 megawatts of recent storage by the top of 2023. EDF’s undertaking, known as Chuckwalla Photo voltaic+Storage, is the most important amongst that portfolio.

Solely a 12 months in the past EDF’s plans would have ranked among the many largest battery initiatives on this planet, however bulletins in current months have continued to high one another. The biggest photo voltaic and storage undertaking presently deliberate within the U.S., Gemini Photo voltaic from Arevia Energy and Quinbrook Infrastructure Companions, can be situated in Nevada with NV Power as offtaker.

Such initiatives have develop into more and more widespread within the U.S., particularly within the Southwest and West. Additionally on Wednesday, regulators in New Mexico accepted 650 megawatts of photo voltaic and 300 megawatts of storage to switch electrical energy the San Juan Producing Station now delivers to Public Service Firm of New Mexico. 

“It is a signal of the instances that an announcement for a 720-megawatt hour undertaking does not elevate eyebrows anymore,” mentioned Dan Finn-Foley, WoodMac’s head of vitality storage. “What’s notable…is how solar-plus-storage methods and contract phrases are being structured, and this gives one other information level.”

“Power storage is a versatile useful resource and it is notable that a lot of that flexibility comes not simply in its operation however in planning,” Finn-Foley mentioned. “Storage may be sized for various durations to fulfill wants, however contract phrases can embody longer or shorter PPAs or totally different cost constructions to make sure flexibility.”

EDF and NV Power signed a 22-year power-purchase settlement. EDF didn’t instantly reply to questions on the PPA’s worth.  

NV Power’s race for solar energy

It’s not EDF’s first take care of NV Power. In 2017, EDF acquired two First Photo voltaic initiatives beneath contract with the Nevada utility. Final 12 months EDF and NV Power inked one other PPA for a 200-megawatt photo voltaic and a 75-megawatt/five-hour battery undertaking. Each that undertaking and Chuckwalla can be situated on the Moapa Band of Paiute Indians Reservation, with the Moapa Tribe receiving land lease and tax funds from undertaking development and siting. First Photo voltaic and 8minute Photo voltaic Power have additionally deliberate photo voltaic initiatives on Moapa Tribal lands. 

The announcement from EDF, and the broader photo voltaic and storage proposal from NV Power, shed extra gentle on how Nevada’s largest utility plans to fulfill new state necessities for 50 % renewable electrical energy by 2030 and 100 % carbon-free electrical energy by mid-century. Final 12 months, regulators accepted the Berkshire Hathaway-owned utility’s plans for 1.2 gigawatts of photo voltaic and 590 megawatts of recent storage. In its newer submitting with the general public utility fee, NV Power additionally requested approval for 600 miles of recent transmission traces to ship energy from the utility’s rising renewables agreements.

Earlier this month, NV Power reported to state regulators that it had exceeded the 2019 requirement that renewables and vitality effectivity account for 20 % of its retail vitality gross sales.
