District heating in the UK: Prospects for a third national programme

The UK has seen periodic attempts to develop large district heating (DH) networks to make use of residual heat from industry and power generation. Under concerns about climate change and energy security, DH has recently re-emerged in policy visions for future heat systems with small decentralised combined heat and power (CHP) generators playing a key role in the establishment of such networks. This paper draws on Stewart Russell's accounts of earlier DH programmes, asking to what extent the reasons he concluded CHP and DH were systematically excluded continue to marginalise the technologies. In spite of governance changes which ostensibly open new opportunities for experimentation, key structural issues challenge the development of decentralised energy, particularly the alignment of the electricity sector to a centralised system and the dependency of local governments with limited capacity on central government. The reluctance of central government to engage in system planning and the failure to integrate policies related to energy production and energy consumption limit the effectiveness of support for DH.
