The UK may have to pay wind farms and power plants to reduce the amount of electricity they produce this summer, because of a proliferation of solar panels on British roofs. National Grid, which operates the UK’s electricity network, must ensure that supply and demand is matched and that the system remains at a stable frequency — so as not to damage TVs, fridges and other electrical appliances. In its 2017 summer outlook report published on Thursday, it said that it may have to issue emergency instructions to electricity generators that do not usually switch on and off to cut their output, in order to the balance the network. It warned that rapid growth in the number of solar panels on the roofs of homes and businesses around the country was reducing demand from the high-voltage national transmission network it has to balance.

National Grid may be forced to pay higher prices to power plants to stop generating electricity this summer as demand for power continues falling to set new record lows. The transmission system operator said power generators must be prepared to offer a fair price to turn down their electricity output if power flows threaten to flood the grid during periods of particularly low demand, such as weekend afternoons or overnight. The expected glut of electricity flips the winter-time challenge of securing enough supply to meet demand. Instead, National Grid will face periods when demand falls and there is more wind and solar power than Britain needs due to record low demand for power through its network of transmission cables. Grid demand has been steadily falling in recent years because more and more companies and households are able to generate their own on-site power through small-scale generators and solar panels.

Wind farms could be paid to switch off their turbines this summer as the growth of solar panels leaves the national network swamped with too much power. National Grid, which manages the network, forecast yesterday that the minimum demand on the high-voltage power grid would fall to a record low this summer because of the continued installation of rooftop panels and solar farms. As more households and businesses generate their own electricity and more solar farms supply power directly into local networks, National Grid has experienced a significant drop in the amount of electricity that needs to be drawn from the national system.
