- Solar capacity: 400 MWac

- PPA term: 25 years, two agreements
- Commercial operation: October 2029
- Local tax revenue: $100 million
EDF Power Solutions North America signed two 25-year power purchase agreements with NV Energy on August 19, 2026. The contracts cover the Winston Energy Project in Lyon County, Nevada. The project pairs 400 MWac of solar with a 400 MW / 1,600 MWh battery. That battery holds four hours of storage.
Power deliveries start in October 2029. Peak construction will employ more than 400 workers. The project pays roughly $100 million in tax revenue over its operating life.
The site sits near the planned route of the Greenlink North line. That 525 kV line runs about 235 miles from Ely to Yerington. NV Energy expects it in service in December 2028. Winston Energy delivers its first power ten months later.
EDF already owns 734 MW of solar and 1,155 MWh of storage in Nevada. Those sit across two operating sites and one project under development. They include the Arrow Canyon solar-plus-storage project and a standalone solar project serving Switch. A Bonanza project rounds out the Nevada list.
“We are delighted by our continued partnership with NV Energy and ability to contribute paired solar and storage solutions which provide efficient, sustainable, and reliable energy to its customers,” said Jacqueline de Fresart of EDF Power Solutions North America.
Why It Matters
Watch the ten-month gap between the two dates. Nevada has stranded solar behind weak transmission before. If the 2028 line date slips past October 2029, a contracted project becomes a curtailment problem.
Developers scouting Lyon County land should track Greenlink construction milestones. The project’s own schedule tells them less.
The 25-year tenor matters just as much. Merchant storage in the West usually signs for seven to fifteen years. Tolling deals run shorter still.
A regulated utility taking 1,600 MWh for a quarter century prices the battery as capacity, not as an arbitrage bet. That structure wins debt at utility terms instead of merchant risk premiums.
Four-hour duration remains the Nevada default. NV Energy is not buying long-duration storage here. It is buying a solar shift. That choice shows where the utility still sees its evening ramp.
Critical Perspective
Neither party disclosed a price. A 25-year PPA tells you the tenor and nothing about the strike, so no one outside NV Energy and EDF can say whether ratepayers bought this capacity well. Nevada regulators will see the number. Readers will not.
The October 2029 date deserves the same caution. That is three years out, and the contract signature is the easiest milestone in the sequence. Permitting, interconnection and the battery order all sit ahead of it.
The economic figures are softer than they look. The $100 million in tax revenue accrues over the full operating life, which runs decades, not over the construction period. The 400 jobs are a peak construction count. Operating a solar plant with a battery takes a fraction of that crew.
One more question worth asking. EDF frames Greenlink North as an asset for this project, but the dependency runs the other way. If NV Energy slips its own 2028 line, EDF holds a signed contract on a site that cannot move power.
