628 Homes, $3.86 Million in Savings: PowerBank Announces Grid Interconnection Milestone on Brooklyn Community Solar Project in Nova Scotia

Brooklyn Community Solar Project Expected to Power the Equivalent of 628 Homes Annually

Enables Residents and Businesses to Access Solar Without Rooftop Installation

Part of Nova Scotia's Ambitious 80% Renewable Energy by 2030 Initiative

Toronto, Ontario, April 23, 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, is pleased to announce the Brooklyn Project has completed the execution of the Standard Small Generator Interconnection and Operating Agreement (SSGIA) for the Brooklyn ground-mounted community solar project (the "Project"). The Brooklyn project is approximately 6.86 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. Following the completion of the necessary permitting and approvals, PowerBank expects to begin construction activities in the Fall of 2026.

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 $3.86 Million in electricity savings for the local community in Annapolis Valley, Nova Scotia. These savings come with the additional benefits of local job opportunities, economic growth, local educational opportunities regarding renewable energy, improved grid reliability, 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 Brooklyn project contributes approximately 6.68 MW DC to the 100 MW AC of planned solar additions that will help reduce fossil fuel reliance and drive local economic development.

This news comes following Earth Day on April 22, observed around the world each year during the month of April, and serves as a powerful reminder of the collective responsibility to accelerate the transition to clean, sustainable energy. The completion of the SSGIA for the Brooklyn project is a meaningful contribution to that mission — and it reflects just one milestone within a growing portfolio of projects at various stages of development. PowerBank currently maintains a 1 GW+ pipeline across North America, including projects in early and late-stage development and projects under construction.

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.
