A project is underway to use excess wind generation to heat Highlands homes. Scottish and Southern Electricity Networks, National Grid ESO, plus partners Delta-EE, Everoze and PassivSystems, think up to 380,000 households could benefit. The 4D Heat pilot, with spending allowed under Ofgem’s innovation programme, will target communities north of the Highlands that are off the gas grid, but already in hot-spots of electrified home heating, and – importantly – where there is potential to expand those hot-spots. If successful, the project addresses multiple problems. National Grid ESO spends tens of millions of pounds curtailing output from wind farms each year. It does this to keep the grid stable. With more wind coming on to the system, there will be more periods of excess generation. Using excess power to heat homes helps solve that challenge. If the heat infrastructure is also made smart, it can become an additional source of flexibility for local and national system operators.
