Differentapproaches can be used to estimate the likely peak demand of a new scheme,however, where new buildings are involved there is always uncertainty aroundhow new buildings will perform in practice. This issue is probably not criticalat this stage and can be refined as the project and phases become clearer,however, an early estimate is for a maximum diversified demand of50-70MW heat.200AlbertEmbankmentFigure TA5.2 Peak energy demandVauxhallNCGM,PatmoreBattersea/NineElmsStew arts Road

The curve takes standard hourlyprofiles for different building types over atypical year and displays the hour with thehighest demand on the left hand side andthe lowest on the right. The load durationcurve is a useful tool in determining thescale of project and technology selection.A load duration curve including all plannednew development in the OA for each phaseis shown below and is discussed further inSection 7.3.Thermal Demand (kW)30,00025,00020,00015,00010,0005,000-Option 5 - Thermal Demand Duration CurvePhase 1+2 Heat DemandPhase 1 Heat Demand0 1,000 2,000 3,000 4,000 5,000 6,000 7,000 8,000 9,000Annual HoursFigure TA5.3 Thermal demand duration curve3.4 Existing buildingsExisting buildings could have a significantimpact on the growth of the scheme inthe future.There are some large commercial buildingsalong Albert Embankment. These are likelyto have central plant and could thereforepotentially be connected relatively easilyto an area wide district heating scheme.Further information is needed in order tounderstand specific opportunities.Individual electric and gas boiler systemsgenerally serve existing residential buildingsin the OA. This makes connections to DHNsmore complex and expensive, although insome cases there will be a significant carbonbenefit at stake. The complexity mainlyarises from the requirement for new hotwater distribution systems within buildings,to supply heat to each dwelling.Retrofitting dwellings in this way wouldtypically be considered when existingsystems are coming to the end of their usefullife, providing an opportunity for offsetcapital costs. However, the economic caseneeds to be analysed over the whole life ofthe systems, as operating costs are typicallyhigher, particularly for electrically heateddwellings.Dwellings on the Patmore Estate haveindividual gas boilers, whereas Chelsea BridgeWharf is electrically heated. Informationhas been requested from Berkeley Homesin respect of St Georges Wharf but has notbeen received.In summary, the existing buildings mentionedwill certainly play a part in the scheme in thefuture, but in the short term they are notconsidered in terms of CO2 savings or centralplant sizing.
