Google and Cypress Creek Break Ground on America's Largest Solar Project

Google and Cypress Creek Energy have broken ground on the Steel River Energy Center in Mississippi County, Arkansas, which will become the largest solar and storage facility in Google's global portfolio and, once complete, one of the largest in the United States. The full three-phase project will deliver 2.5 gigawatts-DC of solar generation and 2.9 gigawatt-hours of battery storage to the regional grid by 2029, enough electricity to power more than 315,000 Arkansas homes annually. Google is serving as both anchor investor and offtaker, supporting the first two phases that will add 1.6 gigawatts-DC of solar and 1.9 gigawatt-hours of storage.

 

Why Pairing Solar With Storage Matters for Data Centre Power

 

The project's design directly addresses a problem central to Google's data centre strategy: sourcing carbon-free power around the clock rather than only when the sun shines. Solar generation peaks during daylight hours, while data centres draw power continuously, creating a mismatch that has traditionally forced companies seeking clean energy to accept gaps in coverage or fall back on grid power from other sources during off-peak hours.

By combining massive solar arrays with advanced battery storage, Steel River is designed to capture the sun's peak daytime output and discharge it later, when demand is highest rather than when generation happens to be strongest. That storage capability is what transforms an intermittent renewable resource into something closer to dispatchable, round-the-clock power, and it is also what makes the facility valuable to the wider grid supporting Arkansas's industrial steel manufacturing and households, not just to Google's own data centre operations.

Building the Project From Domestic Steel

 

The project's construction approach ties directly to its location. Mississippi County is described as the nation's leading steel-producing county, and the facility will be built using entirely US-made structural steel, sourced from US Steel's nearby Big River facility and manufactured at PACO Steel's Arkansas plant. That local sourcing decision links a clean energy project directly to domestic heavy industry rather than importing components from elsewhere, embedding the project's supply chain within the same regional economy it will help power.

That connection reflects a broader pattern in large-scale clean energy deployment, where the demand for solar panels, trackers, batteries and structural steel has become a meaningful driver of domestic manufacturing activity. Google noted that clean energy projects of this kind supported more than 1.4 million American jobs in 2025, positioning its growing US clean energy procurement as a demand driver for domestic suppliers rather than solely an environmental commitment.

What the Project Means for the Local Community

 

Construction of Steel River is expected to create approximately 700 local jobs and generate an estimated $300 million in tax revenue over the project's lifetime, figures that anchor the facility's economic case for the county hosting it. Beyond direct construction activity, Google has committed $5 million to energy affordability initiatives supporting Arkansas residents and K-12 schools, building on its existing Greater West Memphis Energy Impact Fund.

That funding is directed at specific, targeted uses: community solar subscriptions for low-income customers in West Memphis, residential health, safety and weatherization improvements across Mississippi County, and energy efficiency upgrades in Arkansas schools. Structuring the commitment around these particular categories, rather than a general community fund, ties the investment to concrete outcomes that residents can see and benefit from directly, addressing energy costs and housing conditions rather than only the electrons the facility adds to the grid.

Whether the full three-phase build reaches its 2029 completion target on schedule, and whether the domestic steel sourcing model proves replicable for future large-scale clean energy projects elsewhere in the country, will determine how much this milestone shapes the broader pattern of pairing major renewable energy investment with domestic manufacturing supply chains.
