Sleepy Orange is a 500 MW solar and 500 MW battery project, carefully sited on public land administered by the Bureau of Land Management in Lyon County, Nevada. The project is sited to minimize community and environmental impacts while maximizing reliable and consistent energy to support Nevada’s growing energy needs. 

Sleepy Orange is expected to complete construction and begin commercial operation in 2030. The addition of a battery energy storage system (BESS) would provide a consistent, dispatchable energy resource designed to support Nevada’s peak energy demands.

FAQ

How can I learn more about the project and provide feedback?

Primergy appreciates your questions and comments. Please email SleepyOrange@primergypower.com and we will get back to you.

When will construction start, and how long will it take?

Construction is expected to start in 2028 and will last for approximately 24 months.

How reliable is the project’s expected energy production over the life of the project?

The project’s expected energy production is considered highly reliable based on trusted solar resource data, conservative modeling, and proven solar and battery technologies. Independent third-party engineers validate forecasts using standard probability scenarios and account for degradation, auxiliary power use, and Nevada-specific temperature impacts. Long-term O&M agreements, performance guarantees, monitoring, and a defined battery augmentation strategy support reliable performance over the project lifecycle.
