Google Unveils Massive 1.9GW Clean Energy Project
Google announced plans to build its first Minnesota data center in Pine Island, supported by 1.9 gigawatts of clean energy. The project, in partnership with Xcel Energy, will deploy 1.4 GW of wind and 200 MW of solar generation paired with a massive Form Energy iron‑air battery: a 300 MW system capable of supplying its rated power for 100 hours and totaling about 30 GWh, which TechCrunch describes as the largest battery in the world. The agreement uses a “clean transition tariff” structure to de‑risk investment for the utility and ratepayers. Form Energy’s iron‑air chemistry stores energy via reversible iron oxidation (rusting/de‑rusting), targets very low storage cost (company claims ~$20/kWh eventual cost), manufactures in West Virginia, and has raised $1.4 billion to date. A separate Form installation with cooperative Great River Energy will store 150 MWh for 100 hours (1.5 MW peak).
Major cloud operator (Google) announced a large, renewables‑backed data center and an unprecedented long‑duration battery (30 GWh / 100 hours). This affects data center infrastructure, grid integration of renewables, and financing models (clean transition tariff), though it is not a direct AdTech product change.

Google's Minnesota Data Center: A Green Energy Gamble
Alphabet's Google announced plans to build its first data center in Minnesota on a 480-acre site in Pine Island to support AI workloads and its cloud business, under an agreement with utility Xcel. The project has not begun construction and has faced local opposition and a lawsuit challenging its environmental review, though the Pine Island city council approved preliminary plans and financial incentives. Google agreed to deploy 1,400 MW of wind, 200 MW of solar and 300 MW of battery storage to the grid owned by Xcel, with those renewable projects expected online in 2028–2029. Google said it will pay for any required transmission infrastructure and 100% of its energy costs, and will pay a premium under a tariff intended to shield other ratepayers from infrastructure costs. The Minnesota Public Utilities Commission must review the agreement.
Google Invests $1B in Form Energy's Game-Changing Battery
Google is building a new Minnesota data center that will be powered by wind, solar and a long-duration iron-air battery supplied by startup Form Energy. According to reports, Google paid about $1 billion for the battery system, which can deliver 300 megawatts continuously for 100 hours by oxidizing iron (iron-air chemistry). The battery will help balance output from 1.4 gigawatts of wind and 200 megawatts of solar capacity. Form Energy has built a factory in West Virginia, has raised $1.4 billion to date (per PitchBook), and its CEO Mateo Jaramillo said the company is raising a $500 million round and plans to go public next year.
Google Powers Up with Major Clean Energy Deal
Google announced a partnership with Michigan utility DTE to add 2.7 gigawatts of new capacity to power a planned data center near Detroit. The package includes 1.6 GW of solar, 400 MW of four-hour battery storage, 50 MW of long-duration storage, 300 MW of additional 'clean resources' (unspecified sources such as wind, hydro, nuclear or geothermal), and 350 MW provided via demand-response programs. The deal will use Google’s Clean Transition Tariff, a mechanism the company has used previously in a similar agreement with Xcel Energy in Minnesota. Google also pledged a $10 million Energy Impact Fund aimed at reducing utility bills through measures like home insulation. Several details remain unresolved or not publicly clarified, including the exact definition of 'additional clean resources.'
