292 Vauxhall Nine Elms Battersea Opportunity Area Planning Framework4.7.2 WandsworthThere are at least 60 communally heatedhousing blocks in Wandsworth of which 20are in excess of 1MWh, thereby providingopportunities for connections into a widerdistrict heating network connecting toenergy service provision at VNEB.The London Energy Partnership haveproduced a Community Heating Database(http://www.lep.org.uk/projects/toolkits.php) which provides details of communalboilers across London, and the LDA willpublish an interactive London Heat Mapwhich will be available online in Autumn2009. The map below illustrates a sampleof communal boilers in Wandsworth andLambeth that may be possible to connect toa wider district heating network as part ofthe developments at VNEB.Figure TA5.5 Communal boilers in Wandsworth and Lambeth (London Boroughs of Lambeth & Wandsworth)
Vauxhall Nine Elms Battersea Opportunity Area Planning FrameworkTA 05 Energy masterplanMayor of London 2935 Existing gas and electricity infrastructure5.1 Electricity5.2 GasEDF Energy were contacted as part of thework and were asked to comment on issuesof capacity and suitability for embeddedgeneration in the area. They provided thefollowing formal response:“Forecasting load growth across the majorityof our network area has been adjusted toreflect the current down turn in the economywith long term forecasts indicating very lowgrowth levels over the next few years. Thereare a few exceptions where growth continuesnotably the City of London and the ThamesGateway where we will continue to monitordevelopments closely.Whenever presented with new developmentproposals for the Region, the EDF EnergyProjects Gateway team will examine theproposal, its impact on our existing networkand provide an economic design forconnection. The Developer is required tomeet appropriate costs in accordance withthe current industry regulations.Our funding arrangements, which are setin periodic price reviews by our regulator,Ofgem, specifically do not allow us to investin infrastructure ahead of need. The regulatorviews such investment as risky, inefficientand not in the best interests of customers asa whole.For the moment we can say that the networkcapacity for the Region is adequate formeeting existing customer demand. Ourasset replacement programmes provide theopportunity to rethink the way in which ourinfrastructure is developed to meet futurecustomer needs, particularly for connectionsto green and renewable energy sources.”The forecast additional electricity demand forthe OA based on the Option 5 developmentscenario is 50-60MW.The OA is currently supplied with electricityfrom primary sub-stations at Montford Placeand Moreton Street. Whilst it is understoodthat some reinforcement of the MontfordPlace 33/11kV sub-station may be possible,EDF have confirmed that a new primary substationwill be required somewhere withinthe OA. It is recommended that a locationbe identified within the Battersea Nine Elmsarea, as this is the area where the majority ofadditional demand will appear.EDF have advised that the expected footprintfor a 132/11kV primary sub-station to servethe area would be 50 x 50m, which couldbe integrated into a development site. Thisnew facility would have a total capacity of50-60MW. The early cost estimate for anew primary sub-station according to EDFis £15-20m. EDF would typically seek torecover these costs from developers throughconnection charges associated with specificdevelopments. In practice this means thatthe majority of these costs might be met bya single developer who’s development meansthat capacity in the area is exceeded.It is therefore recommended that majordevelopers, potentially with the supportof the GLA/LDA, take collective action toplan for and bring forward this additionalcapacity at an early stage. This collectiveaction would reduce the risk to any singledeveloper, but may require capital supportfrom the public sector.This new infrastructure could be installed byEDF as the incumbent distribution networkoperator (DNO) however it could also beprovided by any other licensed independentDNO (IDNO). A competitive approach toprocurement is recommended. This earlyfunding of infrastructure could potentiallybe recovered through the CommunityInfrastructure Levy, when this arises, orthrough negotiated S106 agreements.Primary sub-stations typically take 3-4 yearsto bring into operation, partly due to verylong lead in times on transformers, andtherefore planning for this at early stage is apriority for the OA.Joint procurement of the high voltageelectricity distribution assets and ofthe waste processing and low carboninfrastructure, as part of a single process,is likely to reduce the capital contributionrequired by developers and minimisethe transaction cost associated with theprocurement process.Gas capacity is believed to be generallyavailable in the OA, however, the level ofdevelopment planned will increase thedemand significantly, particularly at theenergy centres, where gas fired CHP andback up and top up boilers are located.Once the energy centre locations are clearer,an early estimate of the gas capacity shouldbe made and a request placed with a licencedgas supplier for a supply at these points. Thisrequest triggers a capacity study, which willin turn determine the costs of the network,metering and any offsite reinforcementworks required.
