SolarBank Reaches Commercial Operation on New York Solar Project for Honeywell International

Toronto, Ontario, March 21, 2023 — SolarBank Corporation (CSE: SUNN) (“SolarBank” or the “Company”) is pleased to announce the completion of construction on a turnkey behind-the-meter (“BTM”) solar power project in New York state for Honeywell. SolarBank controlled the complete project from origination through completion. The power plant passed its final New York State Energy Research and Development Authority NY-Sun Program inspection and has been placed in commercial operation. SUNN secured nearly $240,000 in NY-Sun incentives for the system.

The system has an installed capacity of 683.55kWdc, and is expected to generate over 753,000kWh of clean, renewable energy in its first year of operation. The renewable energy generated will support Honeywell water treatment systems associated with the restoration of Onondaga Lake in Syracuse, NY, further advancing Honeywell’s commitment to “green remediation” practices as referred to by the U.S. Environmental Protection Agency. The solar installations also will reduce impacts to the electrical grid and lower greenhouse gas emissions.

SolarBank currently operates more than 100 solar plants with total capacity in excess of 60 megawatts.

“Honeywell has been a tremendous partner to us, and we are thrilled that our first announcement as a public company is commercial production of another BTM solar power plant for them,” said Dr. Richard Lu, Chief Executive Officer at SolarBank. “Together, we are creating jobs, supporting local communities, reducing grid strain, and helping to control climate change. With the support of governments throughout North America and initiatives in place for companies to transition away from fossil fuels, we feel the momentum building for solar and are excited about where we are heading.”
