This is the second energy modernisation project undertaken by this forward-thinking NHS Trust, the first being at Heartlands hospital in Birmingham, completed by Cynergin and its partners in 2007.

The Solihull Hospital produced steam in a central boiler house which delivered heat throughout the hospital buildings. But the infrastructure was old, inefficient, and the pipes were expensive to maintain and prone to leaks. So the Trust took a bold decision to de-steam the site and cut back on energy costs, while increasing interior climate comfort for patients, staff, and visitors. The Trust have entered into a unique 15 year Energy Services Contract or ESCO, which will completely reshape the way electricity, heating, air conditioning, and lighting, are delivered to the hospital, saving over 12 million pounds over the term of the contract, and 37,500 tonnes of carbon dioxide.

The new system is designed with a central tri-generation CHP unit, producing 770 kilowattswatt of electricity, and a disaggregated low pressure hot water systems for back-up heating and DHW. A 350kW absorption chiller provides cooling supported by a back-up 350kW conventional electric unit.

Cynergin were principal to the technical design and financial modelling of this project which was partly financed by the Government's Energy and Sustainability Fund with the majority of funding being provided by the Co-Operative Bank. The main contractor is ENER.G Combined Power Limited who guarantee the operating performance and energy savings of the project.

This project constitutes a bespoke, holistic, solution combining both demand-side and supply-side energy issues, self-funding over the term of the contract.
