Canadian Solar Inc. announced that e-STORAGE, its energy storage solutions business, will deliver a total of 420 MWh AC of battery energy storage systems for Drax Group across two projects in the United Kingdom. The projects include a 60 MW /120 MWh AC installation in Marfleet, England, and a 150 MW /300 MWh AC installation in Neilston, Scotland. Both projects are being developed by Apatura, a UK energy infrastructure company specializing in large-scale battery storage and enabling digital infrastructure.
The projects have been acquired by Drax and will become part of Drax's FlexGen portfolio. Battery installations are scheduled to commence in the third quarter of 2026 at the Marfleet site, with the Neilston project expected to start installations in early 2027. Under the agreements, e-STORAGE will supply a fully integrated and commissioned battery energy storage system, including its SolBank 3.0 energy storage batteries.
e-STORAGE will also provide operational services for the project under a long-term service agreement (LTSA) covering monitoring, preventative maintenance, and performance analytics. The combined system supply and long-term service support are designed to ensure consistent operational availability across the lifecycle of the asset. When operational, the systems will enhance grid flexibility in the region and support the integration of additional renewable generation into the UK electricity system.
