The customer

Stratford Eye is a mixed tenure development of offices and apartments, overlooking the Olympics site in East London.

The challenge

To boost London’s green credentials for the 2012 Olympics tri-generation technology was chosen to facilitate the building’s own cooling, heating and electricity.

The solution

ENER-G and Switch2 secured an all-inclusive 15-year contract which covers every aspect of energy management, from utility procurement through to customer care, billing and maintenance. Tackling fuel poverty is critically important to developers, London and Quadrant (L&Q), and Switch2 has worked closely with the client to optimise fuel use.

The ENER-G combined cooling, heating and power (CHP) equipment will reduce the 19-storey building’s CO2 emissions by approximately 93 tonnes per annum – equivalent to the environmental benefits of a 36-hectare forest containing 14,000 trees. The CHP system is highly energy efficient as it recovers heat created in the electricity generation process. In conventional power stations, this heat disappears into the atmosphere and is wasted. Instead, it is used to provide heating, cooling and hot water for the futuristic building.

Stratford Eye uses an ENER-G 110 natural gas-powered reciprocating engine with a synchronous generator, the electrical output of 110kWe and heat output of 181kWh.

The system additionally provides some 130kW of chilled water through an absorption chiller.

The outcome

Switch2 delivers a comprehensive utility management programme that includes metering controls, cash collection and financial administration. The metering controls mean residents in all 160 apartments can cut their utility bills by up to 30 per cent, compared to unmetered supply. Procurement of gas, water and electricity is also being provided by ENER-G.

ENER-G is the only energy business able to deliver this all-encompassing solution that covers everything from the community heating source and electricity supply through to smart-metering, negotiating competitive utility prices and managing cash flow.

Andy Withers, Project Manager of L&Q explains “Stratford Eye was a ground-breaking scheme for L&Q, although not a planning requirement at the time we chose to specify a CHP system for environmental reasons. We were keen to ensure that the eco-friendliness of the system did not compromise affordability for our residents. We, therefore, worked closely with Switch2 to ensure that residents received value for money from the system, with tariffs comparing favourably to the normal utility providers.”
