This paper investigates whether and how Danish-style combined heat and power (CHP) and district heating (DH) can be implemented in the UK in the context of a liberalisedelectricitymarket. There is currently an absence, in the UK, of the Danish system of planning rules and also good tariffs for CHPelectricity exports to the grid that led to the development of the Danish system of CHP and DH. However, there are some changes in UK planning practice that may helpCHP and DH. These would need to be strengthened, but it is also the case that the way the liberalisedelectricitymarket operates in the UK effectively discriminates against small CHP plant selling their electricity to the grid. A Danish system of ‘aggregating’ CHP–DH plant using thermal stores could help to overcome this problem. However, an alternative strategy would be to establish feed-in tariffs for CHP units that are linked to DH modelled on the Danish ‘triple tariff’. This could help the UK's long-term objective of absorbing high levels of fluctuating renewable energy sources.
