Summary of the contracting process

Thames Water Utilities Limited procured a comprehensive combined heat and power (CHP) engine solution for its wastewater treatment estate. The requirement covers new spark-ignition CHP engines, associated connection and operating components, installation, commissioning, planned and reactive maintenance, spare-parts stockholding and technical support. The purpose is to use biogas produced during sludge treatment, reduce gas flaring, maximise electricity and heat generation, improve engine availability and support energy recovery, efficiency and emissions reduction. The work is across Thames Water wastewater treatment sites in England, covering the South East and London areas. It is primarily a goods procurement, with substantial machinery repair and maintenance services included. The buyer expected standardised equipment and support across its CHP estate, while allowing for innovation and changing environmental requirements.

The procurement is complete and Edina UK Ltd was selected for the single lot; the award is recorded as pending. The award date is 5 August 2026, with a standstill period ending on 17 August 2026. The contract is scheduled to run from 1 September 2026 to 1 September 2029, with Thames Water able to extend it by up to five years, to a maximum end date of 1 September 2034. The recorded awarded value is £0 gross. The process used a selective competitive flexible procedure under the utilities regime, with negotiation and refinement stages. Bids were evaluated using 60% technical and 40% commercial criteria. The tender submission deadline was 28 November 2025, and the enquiry deadline was 14 November 2025.

This award indicates demand for suppliers able to deliver a complete CHP asset lifecycle rather than engines alone. A credible competitor would need capability in sizing and supplying units across a broad electrical-output range, integrating engines with wastewater treatment infrastructure, and carrying out installation and commissioning safely. Evidence of dependable planned and reactive maintenance, manufacturer-aligned operation and maintenance support, rapid access to spare parts, and technical assistance would be important. Relevant experience should include biogas-fuelled generation, energy recovery and maintaining varied CHP estates. Suppliers should also be able to address emissions compliance, including methane slip and potential carbon-capture requirements, while proposing practical innovations. Thames Water’s preference for standardisation, serviceability and volume-based value favours businesses with scalable delivery, strong supply chains and consistent support across multiple sites.

Notice Title

Combined Heat and Power Engines

Notice Description

This procurement relates to the supply, commissioning and maintenance support of Combined Heat and Power (CHP) engines across multiple Thames Water wastewater treatment sites to maximise engine availability / performance. The scope includes the provision of new CHP units and associated services to support operational efficiency and energy recovery, as well as spare parts stock holding and technical support. Objectives and Expected Outcomes Effective utilisation of the biogas produced during the treatment of sludge, minimising flaring of gas, maximising electrical heat and power production * Securing Capacity: Ensure supply of CHP Engine requirement through AMP 8 and AMP9 * Standardisation: Promote consistency across the CHP estate to reduce complexity and improve asset availability * Commercial Value: Leverage volume-based incentives and long-term value through strategic sourcing * Serviceability: Ensure availability of cost-effective spare parts and technical support * Efficiency & Sustainability: Support energy recovery and carbon reduction goals by securing high-performance, low-emission CHP solutions * Regulatory Changes: Ensure compliance with evolving regulatory requirements * Innovation: Accommodate benefits from innovation Procurement Approach: A competitive tender process will be undertaken to appoint a supplier capable of delivering the full scope. We anticipate awarding the contract to a single supplier but reserve the right to award to more than one supplier if it is deemed to deliver best value. Background: Thames Water (TW) currently operates 47 Combined Heat and Power Engines (CHP) across 24 wastewater treatment sites. These engines vary in age, size and output, and many are approaching the end of their lifecycle (typically 20 years). Anticipated Requirements: * Replacement of end-of-life engines during AMP 8 with estimated 10 - 16 new engines (Estimated range between 100kW - 1500kW electrical output) expected to be installed within AMP 8 alone. Further new engines will be required for AMP 9 * Specification: to be provided at PSQ * Support innovation: We are always looking for ways to improve what we do, and welcome innovative ideas/solutions * Compliance with evolving environmental regulations, especially around emissions to air (e.g. methane slip and possible carbon capture under the Industrial Emissions Directive) * Integration of AMP 9 requirements, to leverage further standardisation and volume based discounts: The engines on an additional 7 wastewater treatment sites planned to be upgraded in AMP 9 What we anticipate purchasing TW is seeking to procure a comprehensive solution for CHP engines, which includes: * Supply, installation, and commissioning of new CHP engines across the TW estate * Ancillary components required for engine connection and operation * Provision of spare parts to support ongoing maintenance * Planned and reactive maintenance in line with the manufacturers O&M manual * Technical support to ensure safe and efficient operation through the lifecycle of the asset The procurement will cover both replacement of end-of-life engines and new installations to meet growing demand. The current aim is to award a single-source agreement to enable standardisation, improve serviceability, and reduce complexity across the estate.
