Case Study: Largest Supermarket Retailing Company achieves major cost and carbon savings with Centrica Business Solutions CHP

Smart energy creates smarter retail

Largest Supermarket Retailing Company, one of the UK’s largest supermarket retailers, needed a smarter way to generate and consume energy across its warehouses while reducing costs and meeting stricter carbon-reduction requirements. Its large distribution facilities were especially challenging to heat and cool efficiently, making energy use and supply resilience a major concern. Centrica Business Solutions addressed this with a Combined Heat and Power (CHP) solution.

Centrica Business Solutions implemented a containerised ENER-G 1.5MWe CHP unit with an MTU genset and a custom Exhaust Gas Heat Exchanger to support hot water, heating, and low-temperature chilled water for the warehouse. The project is expected to deliver £400,000 in annual gross savings, displace 11,637 MWh from the grid each year, and reduce CO2 emissions by 5,775 tonnes, while creating a blueprint for rollout to other sites.
