THROUGHOUT 2006 the city generated over 190 Gigawatt hours (GWh) of heat and power from renewables and waste.

The majority was distributed through Enviroenergy, the city council-owned heat and power network. The rest of the city's home-grown energy was generated from gas Combined Heat and Power (CHP). The CHP plants are owned by organisations including the district heating network operator Enviroenergy, Alliance Boots and the Queen's Medical Centre. Nottingham's domestic gas consumption fell by 16% from 2003 to 2007 – the largest fall of any council in the East Midlands and largest of all the core cities.

This has been achieved through the work of NEP and local housing associations working on energy efficiency. This puts Nottingham in the top eight per cent of authorities in the UK for domestic energy efficiency.

The impact is that businesses and homes on the heat and power network are protected against rising gas and power prices. The private electricity wire network from the system protects local users from power cuts, as it is separate from the National Grid.
