Google has signed a long-term power purchase agreement for 200 MW of solar energy from the planned Solstice Solar Project in Oklahoma, reinforcing its clean energy supply for regional data center operations.
The deal supports development of a large-scale renewable energy facility designed to strengthen grid capacity while meeting rising electricity demand in the region.
The Solstice Solar Project is a 250 MWdc solar development planned for LeFlore County, Oklahoma, and will operate within the Southwest Power Pool (SPP), one of the fastest-growing electricity markets in the United States.
The location places the project in a key energy development zone benefiting from strong transmission infrastructure and increasing demand from industrial and digital infrastructure users.
Development and Ownership Structure
The project is being developed by Enlight Renewable Energy through its U.S. subsidiary Clēnera Holdings, which is leading execution in the U.S. market.
Construction is expected to begin in 2028, with commercial operations targeted for 2029.
Grid Interconnection and Expansion Plans
The project has completed its system impact study and is expected to receive full interconnection approval in 2026.
Once operational, the facility will deliver electricity directly to Google’s data center operations while supporting broader grid stability in Oklahoma. A future phase could add up to 800 MWh of battery energy storage capacity to enhance reliability and flexibility.
Market Demand and Energy Transition Context
SPP is experiencing rapid growth in electricity demand driven by electrification, industrial expansion, and accelerating data center development. At the same time, the region is retiring significant fossil fuel capacity, increasing the need for new renewable generation.
Nationally, large-scale renewable energy development continues to accelerate across the United States, with projects such as the 120 MW solar PV project planned across Washington and Marion counties in Kentucky reaching financial close as it moves toward grid connection, reflecting a broader push to expand clean energy capacity alongside major developments like the Solstice Solar Project in Oklahoma.
Economic Impact and Industry Significance
The agreement marks a major step for Enlight and Clēnera as they expand into large-scale commercial energy customers in the U.S. market.
The project is expected to create hundreds of construction jobs during development and generate long-term economic benefits through local tax revenue and infrastructure investment in LeFlore County and the wider region.
Google said the partnership supports its goal of expanding clean energy supply while strengthening grid reliability across its operational footprint.
