The environment is a key consideration for the redevelopment of Battersea Power Station. As a regeneration project, our focus is guardianship of the unique heritage of the site, effective resource management and the responsible and innovative provision and use of energy.
Our site is also home to some remarkable species of birds.
THE ENERGY CENTRE
Battersea Power Station will once again be an operational power station, supplying sustainable energy not only to meet its own needs, but potentially those of neighbouring communities.
The site’s Energy Centre will sit ten metres beneath the new riverside park. Its construction involved the excavation of more than 150,000 cubic metres of earth, some of which was taken away using river barges, removing the need for 3,500 heavy lorry journeys on local roads.
Once operational, it will be equipped with three ten-megawatt boilers and three Combined Heat and Power (CHP) engines, each of which will produce up to two megawatts of heat and a further two megawatts of electricity. All this machinery will run on gas at high efficiency, generating energy with a vapour plume. There will also be six chiller units providing efficient air conditioning using non-potable water from an existing on-site borehole. Once the restoration of the Power Station is complete, vapour will be vented through two of the newly-rebuilt chimneys.
Another important feature of the Energy Centre is its large thermal storage system allowing energy to be generated and stored at quiet times for use at periods of high demand, allowing the machinery to be used more efficiently and reducing emissions overall.
Protected Bird Species
Battersea Power Station has been home to two Schedule 1 species; a pair of Peregrine Falcons and Black Redstarts, both species uniquely breeding alongside each other.
Recording of a pair of peregrines at Battersea Power Station started in 2000, one of London’s first peregrine nesting sites. The most successful breeding period for the peregrines coincides with the main construction period. A temporary nest tower was erected on site in 2013, so that works could start where the peregrines had been nesting. Since construction started, the peregrines have successfully fledged 18 juveniles. The restoration of the Power Station will include a new permanent nest site for the peregrines in one of the wash towers.
Black Redstarts have always been an annual breeder at the Power Station. Nests are notoriously hard to find, but fledged young are often seen or heard around the site. Foraging areas have been allocated below the Peregrine Falcon nesting tower and on the brown roofs at Circus West Village.
Circus West Village has been designed to encourage bug and bird populations to use the outdoor spaces. Various bug hotels and bird boxes have been installed in the private and public outdoor areas to provide nesting opportunities and habitat. The bug hotels at Circus West Village are primarily designed for solitary bees to lay their eggs and for ladybirds to hibernate in the winter.
Over 1,000m2 of brown roofs have been created on the roofs of Circus West to provide suitable foraging habitat for the Black Redstarts, a Schedule 1 listed bird species. These brown roofs are planted with drought tolerant sedum and mosses, which provide the ideal habitat for invertebrates and ruderal plants. Pied and grey wagtails also enjoy these areas for foraging.
