TotalEnergies Inks 15-Year Google Ohio Solar Deal

• Google taps TotalEnergies’ 15-year PPA for 1.5 TWh from Ohio’s 49‑MW Montpelier solar farm, fueling data centers and highlighting surging Midwest corporate solar demand.

TotalEnergies signed a 15-year power purchase agreement with Google to deliver 1.5 terawatt-hours of certified renewable electricity from the Montpelier solar farm in Ohio. The project has 49 megawatts of capacity and will feed power to the tech giant under the long-term contract, the companies said. Financial terms weren’t disclosed.

Google has been expanding clean-power purchases to support its data centers and emissions goals, while TotalEnergies is growing its U.S. renewables footprint alongside oil and gas operations. The deal adds contracted offtake for the Montpelier site and underscores demand for corporate solar PPAs in the Midwest amid rising electricity needs.

How will the PPA certify renewable delivery and hourly match Google’s Ohio data center load?

• The PPA bundles energy with timestamped renewable attributes, issuing hourly Energy Attribute Certificates that prove when each MWh was produced.
• Hourly metering from the Montpelier solar plant feeds production data to a certified registry; certificates are minted per hour and tagged to the project and PJM location.
• Google shares data center load profiles at an hourly (or sub-hourly) interval; a matching platform reconciles load and certificates by time and geography.
• An independent auditor verifies metering, certificate issuance, retirement, and the hourly match rate, producing assurance reports for both parties.
• When solar output aligns with the data center’s demand, the corresponding hourly certificates are retired against that hour’s consumption.
• For hours with overproduction, surplus certificates are banked or sold; for shortfalls, the agreement allows procurement of additional hourly certificates from complementary resources.
• Firming and shaping services (potentially including battery dispatch or contracted evening/winter resources) improve the hourly match during non‑solar periods.
• Grid deliverability is addressed via PJM interconnection, with settlement at a defined node/zone and congestion/price risk managed through financial hedges separate from the certificate accounting.
• The PPA requires retirement of certificates in the same market region to avoid double counting and to reflect the data center’s local grid impact.
• Quarterly and annual reports disclose 24/7 match performance, residual emissions for unmatched hours, and any corrective procurement taken to maintain near‑continuous coverage.
