Bloor Islington Battery Storage Project

Bloor Islington Battery Storage Project

Commercial Project, Building Optimization


Starlight’s building is connected to the Islington Subway station (part of the Toronto Transit Commission public transit network). This state-of-the-art Class A office building hosts tenants like the Ministry of Education and Moneris.

The building owners looked for solutions to reduce demand charges (Global Adjustment) and turned to Peak Power for guidance. We installed a 500 KW system to help slash demand charges by 25%.

The system is able to achieve energy cost reduction and revenue generation through Global Adjustment savings and contributions to demand response.

No-Cost Energy Storage Solution

Peak Power signed an 11-year shared savings agreement with Starlight Investments in 2018. The shared savings agreement minimized risk for the building owner and freed up capital for alternative capital projects.

A battery energy storage system (BESS) was installed at Bloor Islington Place, one of Starlight Investment’s premier commercial office buildings. Peak Power was responsible for procuring the battery, submitting utility interconnection documents, and providing an engineered solution that located the BESS in a previously unused outdoor location.

Similar to one of our other downtown Toronto projects, Peak Power was required to manage the subway running nearby (Islington stop) and obtain permission from the Toronto Transit Commission (TTC) to build.




In 2021, SWITCH Power acquired the BESS from Peak Power. SWITCH Power is responsible for the safe operations, maintenance, and commercial management of the asset with Peak Power providing the peak prediction software.

SWITCH Power and Peak Power work together to deliver cost savings for Starlight Investments primarily through the reduction of Ontario’s peak demand electricity charges.
