Heat decarbonisation
Heat network zoning
The strategy identifies indicative zones with potential for heat networks. These zones are not designated but provide a starting point for feasibility studies and stakeholder engagement.
- over 1,550 green spaces in off-gas areas and 760 in on-gas areas show potential for small-scale heat networks
- existing infrastructure and constraints have been mapped
- further analysis and engagement will be required before any programme development
Domestic buildings
- 127,066 domestic properties in the Highlands
- 61% are off the gas grid, mainly using oil (28%) and LPG (3%)
- 6,428 off-gas properties already use low or zero carbon heat
- 19,001 off-gas properties are highly suited for heat pump retrofit
- 29,219 off-gas properties need substantial retrofitting to be heat pump ready
- 44,492 properties are on the gas grid
- 24,338 on-gas properties are highly suited for heat pump retrofit
- 23,613 on-gas properties are heat pump ready
- 12,924 on-gas properties need substantial retrofitting
A fabric-first approach is required due to high levels of fuel poverty.
Non-domestic buildings
- 16,904 buildings with total heat demand of 947,753 MWh/year
- 65% heated by electricity, 17% by oil, 8% by mains gas, 9% by other fuels
