# Google's 1.9GW Renewable Pact Features World's Biggest 100-Hour Battery
Google has unveiled a groundbreaking 1.9GW clean energy agreement with Xcel Energy to power its first Minnesota data center, spotlighting the world's largest 100-hour battery at 30GWh capacity. This deal in Pine Island, Minnesota, combines wind, solar, and cutting-edge iron-air storage to deliver reliable renewable energy for AI-driven data centers, setting a new benchmark in sustainable tech infrastructure.[1][2][3]
Pioneering Clean Energy for Google's Minnesota Data Center
Google's new data center in Pine Island, located about an hour southeast of Minneapolis, marks the company's inaugural facility in Minnesota. Partnering with Xcel Energy, the project secures 1.9 gigawatts (GW) of clean power, including 1.4GW of wind and 200 megawatts (MW) of solar. This renewable mix feeds into a massive 300MW battery from startup Form Energy, boasting 30 gigawatt-hours (GWh) of storage—capable of discharging at full power for 100 hours straight, making it the largest by energy capacity announced globally.[1][2][3]
The battery's iron-air technology stores excess renewable energy during high-production, low-demand periods and dispatches it during peak needs, ensuring grid stability over multiple days. Form Energy, which manufactures in West Virginia and has raised $1.4 billion, is already installing a smaller 150MWh version with Great River Energy in Minnesota.[1]
Innovative Clean Energy Accelerator Charge (CEAC) Model
A key innovation is the Clean Energy Accelerator Charge (CEAC), a novel fee structure allowing utilities like Xcel to adopt emerging clean tech without burdening regular customers. Google pays a premium for potentially risky projects like long-duration batteries, shielding ratepayers while complying with Minnesota regulators. This builds on Google's prior Nevada model with Fervo Energy's enhanced geothermal.[1][2]
Under the agreement, Google covers all new grid infrastructure costs and ensures reliability for the region. The Electric Service Agreement awaits approval from the Minnesota Public Utilities Commission (MPUC), expected in coming weeks.[2][3]
Form Energy's Iron-Air Battery: A Game-Changer for Grid Reliability
The 300MW / 30GWh Form Energy battery stands out as the project's crown jewel, dwarfing existing storage solutions with its 100-hour duration. Unlike lithium-ion batteries limited to hours, iron-air systems use abundant materials for multi-day dispatch, addressing renewables' intermittency—crucial for data center power demands fueled by AI growth.[1][3]
This deployment follows Form's pilot with Great River Energy (1.5MW peak, 150MWh), proving scalability. The $50 million Capacity*Connect Program investment further bolsters Minnesota's grid resilience.[3]
Broader Implications for Tech Giants and Renewable Energy Trends
Google's pact aligns with hyperscalers' race for carbon-free power amid surging AI electricity needs. While rivals like Meta pursue nuclear (e.g., 6.6GW deals) and Microsoft restarts reactors, Google's focus on renewables-plus-storage emphasizes firm, dispatchable clean energy.[4][5][6] Xcel's model could inspire similar utility-tech partnerships, accelerating long-duration energy storage (LDES) adoption nationwide.[1][2]
