PowerBank Achieves Key Grid Interconnection Milestone for Sydney Community Solar Project in Nova Scotia

Sydney Community Solar Project to Deliver Clean Energy Equivalent to 222 Homes Annually

Enables Residents and Businesses to Access Solar Without Rooftop Installation

Advances Alignment with Nova Scotia's 80% Renewable Energy Target by 2030

Toronto, Ontario, April 30, 2026 — PowerBank Corporation (NASDAQ: SUUN; Cboe CA: SUNN, FSE: 103) ("PowerBank" or the "Company"), a leader in North American energy infrastructure development and asset ownership, announces execution of the Standard Small Generator Interconnection and Operating Agreement (SSGIA) for the Sydney ground-mounted community solar project (the "Project"). The Sydney project is approximately 2.43 MW in size.

The Project has also received the necessary permits from the municipality. Given the successful completion of the SSGIA, PowerBank will now be proceeding to environmental permitting. PowerBank targets commencement of ground preparation in Fall 2026 for the Sydney project, subject to final permitting and financing.

The Project is owned by AI Renewable Flow-through Fund and PowerBank is the lead developer for the Project. PowerBank has partnered with local Nova Scotia's trusted engineering firm, Trimac Engineering, to deliver the Projects. PowerBank has been at the forefront of community solar development in the United States with over 50 MW of community solar projects completed and is proud to be deploying its expertise in Canada as the community solar market develops there.

Over the lifetime of the Project, it is expected to generate approximately $1.79 Million in electricity savings for the local community in Cape Breton, Nova Scotia. These savings come with the additional benefits including local job creation, economic activity, and emissions reductions.

Community Solar is a cornerstone of Nova Scotia's bold commitment to achieve 80% renewable energy by 2030 and net-zero by 2035.

Unlike traditional rooftop systems, community solar allows renters, businesses, and homeowners to subscribe to the solar farm and receive bill credits and savings of $0.02/kWh—without installing any equipment. Project feeds directly into the local electricity grid and offers a flexible, accessible way for Nova Scotians to participate in the clean energy transition. As one of only four community solar contracts awarded under the program so far, the Sydney project contributes approximately 2.43 MW DC to the 100 MW AC of planned solar additions that will help reduce fossil fuel reliance and drive local economic development.

The Project leverages PowerBank's proven execution capabilities and strategic partnerships. With over 100 MW of projects built and a 1+ GW development pipeline, PowerBank brings institutional-grade development expertise to Atlantic Canada. The Project's clear timeline ensures near-term EPC revenue generation, and positions PowerBank to obtain additional development contracts in the high-growth community solar market. All MW numbers presented as MW DC unless otherwise specified.
