① Sunrun announced a partnership with Tesla and Renew Home to supply power, with shares surging over 31% to $16.79 in early trading;
② The three companies will jointly build a platform capable of providing 16 GW of power, integrating hundreds of thousands of home batteries operated by Sunrun and Tesla, as well as 8 million smart thermostats managed by Renew Home.
June 25 – U.S. residential solar provider Sunrun saw its shares soar after announcing a partnership with Tesla and Renew Home to supply power to data centers and utility companies.
Specifically, Sunrun (ticker: RUN) rose more than 31% to $16.79 in early U.S. trading, hitting its highest level since March 2.
In a statement on its website on Wednesday (June 24), Sunrun said the three companies reached an agreement that day to provide more than 16 GW of ‘flexible energy capacity’ to hyperscale data centers and utility companies.
The press release stated that the agreement establishes a framework for the three companies to aggregate millions of existing demand-side and energy output devices across U.S. states into ‘local, turnkey solutions’ — without requiring power buyers to invest in additional hardware, software, interconnection, water resources, or land.
The three companies will jointly build a platform capable of providing 16 GW of power, integrating hundreds of thousands of home batteries operated by Sunrun and Tesla, as well as 8 million smart thermostats managed by Renew Home.
These power resources will be opened to AI data center developers on a ‘first-come, first-served’ basis and will also provide power support to PJM Interconnection LLC, the largest grid operator in the United States.
The press release stated that the new partnership is a win-win-win ‘for customers, for communities, for the economy’: residential users, data centers, and utility companies can all benefit from the scale, speed, and cost-efficiency improvements brought by the framework.
Sunrun CEO Mary Powell wrote: ‘The 19th-century grid cannot meet the demands of innovation in 2026. When data centers need to reduce operating loads during the most expensive and stressed times of the day, we can activate distributed power plants to help them obtain the power they need while avoiding expensive new infrastructure costs for American households.’
The recent artificial intelligence boom has driven a surge in electricity demand, placing enormous pressure on the power grid. Companies participating in the collaboration stated that U.S. power infrastructure is currently configured primarily to meet demand during a limited number of peak hours, resulting in substantial amounts of expensive generation resources sitting idle for most of the time.
Citing a report by consulting firm Brattle Group, Sunrun noted that improving the utilization efficiency of the existing power grid could save $110 billion to $170 billion in electricity costs over the next decade and accelerate the pace of data center interconnection.
