District heating

District heating efficiently delivers low-carbon, cost-effective heat. However, currently just 2% of the UK’s heat is supplied by district heating networks. With an estimated 50% of buildings in the UK located in areas of suitable density for heat networks, the system has the potential to have a far greater impact.

Gren supplies heat to homes, hospitals, schools and industry.

Combined Heat and Power

Combined Heat and Power (CHP) is a highly efficient process that captures and utilises the heat that is a by-product of the electricity generation process. By generating heat and power simultaneously, CHP can reduce carbon emissions by up to 30% compared to separate means of conventional generation via a boiler and power station.
