Background to Strategy Local government’s main priorities re energy? • To reduce fuel poverty Background to Strategy Local government’s main priorities re energy? • To reduce fuel poverty • To reduce carbon emissions in their area • To reduce running costs of Council owned public buildings Aberdeen City Council 2006

Background to Strategy In Aberdeen all of these factors were important but the primary Background to Strategy In Aberdeen all of these factors were important but the primary driver was fuel poverty. Aberdeen City Council Housing Stock = 23, 500 1999 adopted Affordable Warmth Strategy Vast majority of low rise homes had gas central heating and basic insulation (loft and cwi). (Investment over many years through Housing Capital Programme) Policy to target the least thermally efficient homes - mainly multi storey flats Aberdeen City Council 2006

Background to Strategy In 2001 Council commissioned options appraisal of all 59 multi storey Background to Strategy In 2001 Council commissioned options appraisal of all 59 multi storey blocks (4, 500 flats) All had either electric storage or warm air heating 70% in fuel poverty Recommended install CHP in clusters of multis Appointed a CHP Engineer through tendering process to work up a costed Feasibility Study for a cluster of multis Aberdeen City Council 2006

Background to Strategy Whole life costings considered: CHP is higher in capital costs, but Background to Strategy Whole life costings considered: CHP is higher in capital costs, but considerably lower in running costs – could take occupants out of fuel poverty If the Council fully fund the connection of all 59 multis to CHP/DH scheme would take 30 years+ for this to be affordable Commercial ESCos could gain access to 3 rd party investment to accelerate deployment but required returns on investment would significantly increase heat cost - undermine the objective of reducing fuel poverty Aberdeen City Council 2006

Background to Strategy In 2002 the Council established… Aberdeen Heat and Power An Independent, Background to Strategy In 2002 the Council established… Aberdeen Heat and Power An Independent, not-for-profit company, limited by guarantee, to develop and manage DH / CHP schemes “for the benefit of the people of Aberdeen” Aberdeen City Council 2006

Why separate company and not in-house ? Council did not have in-house skills e. Why separate company and not in-house ? Council did not have in-house skills e. g. procurement, finance, engineering Independent Company can be just that – independent Project management, operations, maintenance and some risks transferred, but Council retains influence/direction Guaranteed continuity for Council – walk-in rights should Company fail Council get on with running the Council, AH&P get on with running a District Heating business to deliver affordable heat.

Heat Network Projects - Capex For housing, full capital costs need to be covered. Heat Network Projects - Capex For housing, full capital costs need to be covered. If capital had to be borrowed the heat charge would increase and occupants would be back in fuel poverty To date full capital for the housing from combination of: – Housing Capital Programme - at approx same unit cost as low rise housing having electric changed to gas heating – Charge to owners for connections – Government grants - Community Energy Programme Grant (CEP) – from Scottish Government – Fuel utility grants – EEC, CERT, CESP, ECO For public buildings used CEEF or Spend to Save. Means AH&P has no borrowing to repay Aberdeen City Council 2006
