About the Project

Tara BESS, formerly Grey Owl Storage, is a 400-megawatt (MW), 1600-megawatt hour (MWh) battery energy storage system (BESS) proposed for development in the Municipality of Arran-Elderslie.

The project was awarded a 20-year energy storage contract by the Independent Electricity System Operator (IESO) in May 2024, in the IESO’s LT1 procurement.

Tara BESS will store and discharge electricity to-and-from the Ontario’s power grid, helping meet the province’s growing electricity needs.
