On July 28, Tesla inked a power purchase agreement with Stellar Renewable Power, a renewable energy developer supported by private equity firm KKR. The contract covers electricity from a massive 1 GW solar farm paired with a 1 GW/4 GWh battery storage system in Navajo County, Arizona.
Stellar Renewable Power, founded by KKR in 2021, focuses on utility-scale solar and storage projects. The Navajo County project cleared key regulatory milestones in December 2024, receiving a Special Use Permit that greenlit construction plans. Specifics of Tesla's deal with KKR, including price and contract length, remain confidential.
Tesla already operates several Virtual Power Plant programs in Arizona. These programs link customer Powerwalls to create a grid-responsive energy network. Participating homeowners can earn around $400 to $800 annually per Powerwall by allowing Tesla to use their stored energy during peak demand periods. On top of this, Tesla has deployed Megapack battery systems to complement solar sites statewide, giving the company influence over both energy generation and storage.
KKR's entry into solar via Stellar Renewable Power is a strategic move to expand its footprint in large-scale renewables. Partnering with a creditworthy buyer like Tesla simplifies financing for costly infrastructure projects. Still, the 1 GW solar farm with 4 GWh of storage represents a major undertaking, with potential challenges including construction delays, permitting hurdles, and supply chain issues.
