EXECUTIVE SUMMARY

Battersea Power Station is an emerging working on the project since 2013 to luxury mixed-use development and is design and build a solution that would regenerating the former power station allow the power station to once again into new homes, shops, restaurants, be a source of energy. This involves the CLIENT offices, and over 19 acres of public construction of a modern day energy Battersea Power Station space, with the first phase already open. centre in the basement of the power Development Company Battersea Power Station Development station and a district heating and cooling Company had a vision to bring the power network to supply heating, cooling and PROJECT Battersea Power Station station back to life and so we have been electricity to the entire 42-acre site.

VITALOFFICES | LONDON | BLACKBURN | GLASGOW www.vitalenergi.co.uk The North East and South West chimneys have been adapted to be utilised by the energy centre’s flues. The exhaust flues for the boilers and CHPs will rise up the building using the wash tower and then through the existing chimneys in a total length of 960m.

This energy centre will be a hugely important part of the new neighbourhood town centre at Battersea Power Station, supplying energy not only to its own community but potentially to other local residents nearby. This energy centre provides an important link to this fantastic building’s past, as a local source of power in the nation’s capital once again.

GARY EDWARDS, HEAD OF TECHNICAL SERVICES AT BATTERSEA POWER STATION DEVELOPMENT COMPANY (BPSDC) OUR SOLUTION Our solution entails the construction emissions by 5,000 tonnes per year heating and hot water individually, but of a district heating and cooling network which is the equivalent of taking up to instead will be connected to the main and a 73,000 sq ft basement energy 1,000 cars off the road each year, with a energy centre to provide additional centre, which will be split over two levels. total pipe length of around 6.4km which resilience to the network. At full build, the energy centre will have is the length of over 2,500 double decker Increasing Efficiencies a total heating capacity of 42.75MW, buses. We have increased the efficiencies of cooling capacity of 30MW and electrical Reduced Noise Emissions the solution by designing a bore hole capacity of 7.3MW.
