The 494 MW York Energy Centre (YEC) is located northwest of Newmarket, Ontario in the Township of King. Capital Power acquired its share in the York Energy Centre from Veresen Inc. in April 2017. The facility is jointly owned in a 50/50 partnership and is operated by Capital Power. York Energy Centre is fully contracted with the Ontario Independent Electricity System Operator until 2035.

York Energy Centre Upgrades Project
In Q1 2025, Capital Power completed equipment upgrades at the YEC that provide an additional 38 MW of electricity generating capacity. The upgrades were completed under the Ontario Independent Electric System Operator’s (IESO) Same Technology Upgrade Solicitation, which called for capacity increases from existing facilities. The upgrades improved efficiency, increased generation capacity and reduced NOx emissions at the YEC.
York Energy Battery Energy Storage System
Capital Power built and commissioned its first two battery energy storage projects in Ontario in August 2025, one of which is the York Energy Battery Energy Storage System (YEC BESS). Located beside Capital Power’s York Energy Centre, the YEC BESS facility provides up to 120 MW of power storage, with electrical energy output for up to four hours.

Hydrogen Feasibility Study
In 2023, we were selected as recipients of Ontario Energy’s Hydrogen Innovation Fund. Through this funding, we’re exploring hydrogen blending at our Goreway Power Station, East Windsor Cogeneration Centre, and York Energy Centre, using various mixes of hydrogen (from 5% to 15%). Engineering studies will be conducted at each site to evaluate the impacts on the natural gas turbine’s performance, maintenance, operability, emissions, and safety considerations, as well as how hydrogen could be procured, transported, and stored.
