USA: ON.Energy, a system integrator and project developer, has announced a 5 GW transformer supply agreement with Prolec GE for data centre and renewable energy applications in the United States.
The deal will support the rapid deployment of ON.Energy’s AI-based uninterruptible power supply (UPS) technology across data centre campuses beginning in 2026. Under the agreement, Prolec GE will manufacture and deliver three-phase pad-mount transformers specifically designed for ON.Energy’s medium-voltage systems.
These transformers will be installed at grid-connected and fully behind-the-meter AI data centres, helping to stabilise AI workloads, regulate ramp rates, and protect both the data centres and the electrical grid from voltage fluctuations.
Transformer supply chains have been under pressure for some time. At the 2023 RE+ trade show, EPC contractors reported lead times increasing from 12 months to as much as 32–36 months, including procurement cycles. While the situation has eased slightly, equipment availability continues to be a key constraint for energy and infrastructure projects.
ON.Energy’s agreement with Prolec GE ensures access to high-quality transformers to meet growing demand and mitigate delays in critical deployments.
Earlier in January, ON.Energy secured a $77.6 M construction credit facility with Pathward, NA, and BridgePeak Energy Capital to develop its 160 MWh Palo de Agua BESS portfolio. The portfolio, located across Texas, includes projects such as Poplar, Ft. Stockton, Mesquite, North Pecos, Colorado, Colorado 1, Andrews, Fathead 1, Fathead 2, and Badger BESS, each with a capacity of 9.9 MW / 20 MWh.
This collaboration underscores ON.Energy’s commitment to supporting reliable AI-driven infrastructure and expanding renewable and energy storage solutions across the US.
