NI Water has completed the second phase of its solar programme, installing panels at five operational sites in Antrim, Ballymena, Magilligan, Derg and Killyhevlin.
These new installations, combined with panels added during the first phase, form part of the company's ongoing drive to achieve net-zero operations and are expected to cut carbon emissions by approximately 250 tonnes by March 2026.
Funded with around £3 million from the Department for the Economy's Energy Invest to Save initiative, the project has brought the total number of solar panels installed by NI Water to nearly 5,000 across eight sites. The panels provide a combined capacity of roughly 2.2 Megawatts (MW), generating electricity for on-site use and reducing demand on the main power grid. The system produces enough energy to power approximately 815 homes.
Dr Sara Venning, CEO of NI Water, highlighted the operational benefits, stating that the company is "constantly seeking new ways to decarbonise our power and benefit the local economy. By continuing to innovate, we are not only reducing our reliance on the electricity grid but also ensuring greater cost resilience in our operations. We are exploring further solar investment opportunities at energy intensive sites in collaboration with our partners to continue our transformation journey."
The project demonstrates strategic infrastructure investment in renewable energy, supporting both environmental targets and operational efficiency while contributing to Northern Ireland's energy security.
