Scottish Water and the Greater Glasgow and Clyde NHS Board are seeking supply chain interest in the potential procurement of a low carbon/renewable electricity supply via a Private Wire Power Purchase Agreement with an estimated value of £60 million.

The contracting authorities are exploring the potential procurement of a low carbon/renewable electricity supply to the water company's Shieldhall Wastewater Treatment Works, and the GG&C NHS Board's Queen Elizabeth University Hospital.

The supply is required to be delivered directly to Shieldhall WWTW and Queen Elizabeth University Hospital, via a private wire connection, and meet specific technical and delivery requirements.

In particular, the authority is seeking to understand the extent to which the market can provide:

• A low carbon/renewable electricity supply of 37 GWh per annum for use at the authorities' sites;
• Delivery of the electricity via a private wire infrastructure that does not rely on the public electricity grid;
• Full commissioning and operational readiness of the solution by 1st January 2027
• Technical feasibility of locating generation infrastructure within the vicinity of the sites to enable a private wire connection that minimises transmission losses and aligns with planning and development timescales.

The early market engagement exercise is being conducted jointly between Scottish Water and NHS Greater Glasgow & Clyde, with NHS National Services Scotland acting in an advisory capacity.

The engagement is part of a preliminary market consultation and is intended to inform the authorities’ understanding of local market capability and to determine whether a competitive procurement procedure is appropriate. The primary focus is to provide market intelligence, solution availability and perceived risks and opportunities.

Current estimated total value of £60 million (excl VAT) is indicative over a 10-year period based on current prices
