NI Water has completed the second phase of its solar programme across five sites in Antrim, Ballymena, Magilligan, Derg, and Killyhevlin, advancing its goal of becoming a net-zero business. Supported by around £3 million from the Department for the Economy’s Energy Invest to Save initiative, the new installations add to panels installed last year, bringing the total to nearly 5,000 across eight sites. The combined 2.2MW capacity can generate enough electricity to power approximately 815 homes, reducing reliance on the main power grid and cutting carbon emissions by an estimated 250 tonnes by March 2026.

Infrastructure Minister Liz Kimmins praised the programme, noting the progress at Antrim Wastewater Treatment Works and commending NI Water for its efforts to deliver clean electricity while tackling the climate crisis. Economy Minister Dr Caoimhe Archibald highlighted that the scheme is part of over 160 projects funded under the initiative, covering schools, libraries, and hospitals, and emphasised the benefits of strategic renewable energy investment for energy security, economic growth, and job creation.

Dr Sara Venning, CEO of NI Water, said the milestone marks a major step toward the organisation’s climate goals. As Northern Ireland’s largest electricity user, NI Water is exploring innovative ways to decarbonise power use, reduce dependence on the grid, and increase operational cost resilience. The company plans to pursue further solar investments at energy-intensive sites in collaboration with partners to continue its decarbonisation journey.

The project demonstrates how targeted renewable energy investment can drive sustainability, economic benefits, and long-term energy security while supporting Northern Ireland’s broader climate strategy.
