Google Acquires Steel River, Nation's Largest Solar Project, for $3.5 Billion

Groundbreaking for the Steel River Energy Center is set for July 14 in Wilson, Arkansas, with Cypress Creek Energy leading the ceremony and the project billed as the nation’s largest solar project.
Financing for the Steel River project totals about $3.5 billion, secured by Cypress Creek last month, providing the long-term revenue stability needed to construct the three-phase development and its 12 GW of solar commercialized to date with a 20+ GW pipeline.
Cypress Creek has a sizable track record, having commercialized roughly 12 GW of solar projects and maintaining a pipeline exceeding 20 GW, underscoring its capability to support large-scale solar ventures for data-center clients.
The deal follows additional Arkansas activity, including a 100 MW PPA with Treaty Oak signed in November, illustrating Google's ongoing expansion of renewable energy procurement in the state.
Engie’s 24/7 carbon-free energy partnership with Google in Germany was extended to 2030, with a plan to deliver hourly green energy backed by battery storage and pumped hydro, targeting about 85% carbon-free operations in Google’s German operations by 2026 and integrating volumes from Google’s PPAs with third-party providers.
Google has signed a deal to buy all the electricity from the Steel River Energy Center in Arkansas — a project billed as the largest solar development in the United States. At full buildout, the facility will deliver 2.45 GW of solar power and 2.9 GWh of battery storage, according to PV Magazine USA.
The deal is structured as a virtual power purchase agreement, or vPPA — meaning Google pays a fixed price for electricity sent to the grid and receives the environmental credits tied to the solar output. Phase 1 is set to come online in 2029, delivering 1.6 GW of solar and 2 GWh of storage, Data Center Dynamics reported.
Developer Cypress Creek Energy will hold a groundbreaking ceremony on July 14 in Wilson, Arkansas. The event marks the official start of construction on a three-phase project that has already locked in about $3.5 billion in financing, secured by Cypress Creek last month, according to Commercial Appeal.
Cypress Creek is no newcomer to large-scale solar. The company has commercialized roughly 12 GW of solar projects and holds a pipeline of more than 20 GW. That track record helped it attract the long-term revenue commitment from Google needed to close the financing, PV Magazine USA reported.
In a vPPA, the buyer does not receive electricity directly. Instead, Google pays Cypress Creek a fixed price per megawatt-hour. The power goes to the grid. Google gets the environmental credits — called renewable energy certificates — that come with the solar output. Those credits let Google count the clean electricity against its emissions.
This structure is key to financing. The fixed-price contract gives Cypress Creek a steady, predictable revenue stream. Lenders see that as low risk, which is how the project attracted $3.5 billion in funding, according to Investing.com. Google will take 100% of Phase 1 output under this arrangement.
Steel River is not Google's only renewable move in Arkansas. In November, Google signed a separate 100 MW power purchase agreement with Treaty Oak, showing a pattern of stacking clean energy deals in the state. The company's West Memphis data center is a key driver of that demand, AOL reported.
The deals reflect Google's wider effort to cut its carbon footprint. The company has faced scrutiny over how grid-delivered renewable energy actually reduces emissions in practice. When solar goes to the grid, the offset is indirect — the local grid mix, not the data center, uses the clean power directly.
Separately, Google extended its 24/7 carbon-free energy partnership with French energy company Engie in Germany through 2030. The goal is to match Google's German electricity use with clean power on an hourly basis — not just annually, which is the easier standard most companies use.
The partnership uses battery storage and pumped hydro to back up the green power supply. Google is targeting roughly 85% carbon-free operations at its German facilities by 2026. The plan also pulls in electricity from Google's power purchase agreements with other third-party providers to hit that target.
