Sarah Hughes, President and CEO, GrandBridge Corporation, commented:

"GrandBridge is committed to developing solutions that enable immediate capacity growth while preserving our ability to connect future customers. We are taking a proactive approach in response to significant growth in energy consumption and peak demand experienced by our electricity distribution company, GrandBridge Energy, driven by electrification and growth in our communities."

"Solar generation and battery storage solutions can be developed in relatively short timeframes and at competitive costs, alleviating the pressure of securing incremental transmission capacity. Combined with other innovative grid solutions — including GridShare, GrandBridge Energy's new Local Capacity Auction program, which provides price signals for customers to participate in local grid events — these resources can form part of an affordable toolkit to help limit grid congestion."

"PowerBank is a like-minded and experienced partner in renewable energy and battery storage, and we are excited to co-invest in energy solutions that support our customers while enhancing the performance, reliability and resiliency of the electricity grid in Southwest Ontario."

Dr. Richard Lu, President and CEO, PowerBank Corporation, commented:

"We are proud to sign this co-development agreement with GrandBridge Corporation, marking a significant milestone for PowerBank's presence in the Ontario market. PowerBank has a long history in Ontario, beginning operations here in 2013, and this partnership reflects our commitment to deploying our development and construction expertise to meet the province's rapidly evolving energy needs. GrandBridge's deep roots in the communities they serve, combined with PowerBank's expertise in solar and battery storage development, creates a powerful partnership to deliver clean, reliable energy solutions. PowerBank has developed over 100 megawatts of renewable energy projects across North America, and we look forward to bringing that experience to this partnership. Together, we are well-positioned to respond to the growing demand for local generation capacity and contribute to the long-term resilience of Southwest Ontario's electricity grid."

Key Terms of the Co-Development Agreement

The Agreement establishes a collaborative framework for developing electricity storage and generation projects with nameplate capacity of 2 MWac or greater within GrandBridge Energy's service territory in Ontario, Canada. The projects are intended to be developed for submission under Independent Electricity System Operator (IESO) Request for Proposals (RFPs), Local Generation Programs, and alternative procurement opportunities including Virtual Power Purchase Agreements (VPPAs).

Under the Agreement, PowerBank and GrandBridge will collaborate exclusively during a three-year development period on qualifying projects within the defined territory, which encompasses the City of Brantford, the City of Cambridge, the Township of North Dumfries and the County of Brant.

The partnership features an 80/20 ownership structure, with GrandBridge Corporation holding an 80% ownership interest and PowerBank Corporation holding a 20% ownership interest in projects upon Financial Close. This structure may be adjusted if First Nation partners participate, in which case the 80/20 split would apply to the remaining ownership after First Nation participation.
