• Context
• 2008 Energy Strategy Framework for PUSH
• baseline, forecasts and targets
• identification of policy development issues
  associated with delivering reductions in carbon

Heat Mapping

• Database - current and future heat demand and
  supply from industrial, commercial, and domestic
  sources across the County.
• Includes data on housing, industrial
  installations, offices, retail establishments,
  hotels, hospitals, government offices, schools,
  leisure centres, Energy from Waste facilities,
  and Combined Heat and Power facilities.
• Model - capable of spatially representing
  concentrations of heat load throughout Hampshire
  to help inform planning decisions consistent with
  the delivery of decentralised energy.

How the model works

• GIS-based map consisting of various data layers
  which can be switched on or off according to
  the requirements of the analysis being
  undertaken.
• Two main datasets discrete layers which are
  represented by point sources on the map, and
  aggregated layers which are combined datasets
  represented by colour-coded squares at a scale of
  1km sq.

7
Discrete Data point source
Can identify the heat load for each location. The
size of the icon indicates the intensity of the
heat demand.
Leisure Centres
Hospitals
Large Industries
8
Aggregated Data 1km sq.
The intensity of the colour represents the heat
load for e.g. retail across Hampshire. The darker
the colour, the greater the heat load.

Future heat load
Illustrates future additional heat loads for
permitted developments up to 2012.
Future domestic Future industrial Future retail

Applications (illustrative examples)

• Heat load vs Heat output - identifying potential
  CHP schemes for existing Energy from Waste
  facilities
• Planning tool potential for linking new waste
  infrastructure with CHP
• Retro-fitting - potential to replicate existing
  CHP schemes elsewhere in the County

CHP potential from EfW
Chineham
Potential Heat Source of EfWs 26.5MW which is
enough to meet the heat load of all the hospitals
in Hampshire

Retro-fitting
The introduction of CHP in this area in
Southampton clearly demonstrates a reduction in
heat load in this area.
16
Retro-fitting
Where else in the County could this case study be
replicated?
Winchester?
Basingstoke?

Summary

• Developing an evidence base for strategic energy
  planning
• Use of heat mapping to exploit existing and
  potential opportunities for decentralised and
  renewable or low carbon energy
• Working in the context of partnerships e.g.
  Project Integra, PUSH . Hampshire Local Area
  Agreement 2008-11
