Tender: Long Term Power Purchase Agreements

About

United Utilities is committed to building a greener energy portfolio that reduces operational carbon emissions and supports our ambition to achieve net‑zero greenhouse gas emissions by 2050. As one of the largest water and wastewater service providers in the UK, we operate more than 100 water treatment works and 575 wastewater treatment works across the North West of England. These sites have significant energy demands and require robust power resilience to maintain essential services for our customers. Our operational footprint across the region presents substantial opportunities to integrate low‑carbon and renewable energy solutions. Many of our sites have available land or roof space suitable for on‑site generation. In addition, we are seeking opportunities for work with existing or upcoming renewable generation assets close to our operational sites to develop private‑wire Power Purchase Agreements (PPAs). Together, these opportunities support our drive to reduce operational emissions and contribute to a greener, stronger, and healthier North West. To advance this ambition, we are seeking long‑term Power Purchase Agreements through a procurement process structured into three parts: Part 1: Existing Generation: Low‑carbon or renewable generation assets that are currently available—or expected to become available—for private‑wire connection within the North West of England. Part 2: Site‑Based Development: Low‑carbon or renewable generation projects that can be developed on United Utilities‑owned land within the region. Part 3: Site‑Based Development (Roof‑Mounted): Solar PV installations that can be developed on suitable roof areas across United Utilities’ property portfolio in the North West. Suppliers may bid for all three parts or select any individual part that aligns with their expertise, capabilities, and experience.
