Shared Responsibility - Npower

Corporate Responsibility Report 2003Use of ResourcesImproving the efficiency in the use of naturalresources is a key part of moving towards a moresustainable future. Improving the efficiency ofour power stations has always been importantand will become increasingly important after theEU Emissions Trading Scheme begins.Dolgarrog Hydro Power Station in North Waleshas a capacity of 39MW.Stanley Mills began operating in its reliabilityphase (840kW) in autumn 2003. During thedevelopment and construction of the StanleyMills Scheme, our hydroelectric developmentteam worked closely with the Tay SalmonFisheries Board to ensure that appropriatemeasures were incorporated into the schemeto protect local salmon.BiomassWe have undertaken trials of wood co-firing atour coal-fired power stations – Didcot, Tilbury andAberthaw. At Aberthaw we have started trials todirectly burn biomass in the boiler. This schemewill use wood from local forestry sources andis supporting the Welsh Forestry Industry.If successful, this would lead to construction ofan on-site wood processing facility that wouldenable the station to use purpose grown energycrops in the future.Over the last year we reviewed the potential forefficiency improvements at our power stations.The review identified the marginal costs ofcarbon abatement and the total amounts ofcarbon reduction available, which we will takeinto consideration when considering whatimprovements we can make.Use of resources is one of the key environmentalaspects of our office-based activities. All our majoroffice buildings are now covered by an EMS andhave targets for improvements in energy and wateruse. npower introduced a number of resourcesavingmeasures as part of their EMS, including:• Encouraging staff members to turn offmonitors and light switches when not in use.• Installing a company-wide car share databaseand a company transport charter.• Monitoring paper use within offices, usingonly sustainably-sourced paper and settingphotocopiers to default to double-sidedprinting.• Improving waste management at all sitesand introducing paper recycling across thebusiness.Use of Resources in BuildingsRWE npower HeadquartersUse of Resources in Buildingsnpower Buildings100007500500025003,5473,3318,4497,8057,6636,28360,00045,00030,00015,00036,35024,74844,19545,896200220030 0479323GasMWhElectricMWhWaterm 3GasMWhElectricMWhWaterm 322
