Keeping the electricity grid in balance allows greater integration of renewable energy. It reduces the need for combustion power plants to run throttled back in response mode, allowing them to operate more carbon-efficiently and generating their full potential output.
And it means a better deal for consumers by reducing the risk that renewable power plant will be paid not to generate at times of high supply and low demand.
Energy balancing helps keep the lights on, by avoiding rapid changes in frequency (the balance between supply and demand).
This is increasingly important as we use more renewable energy and phase out less environmentally friendly power stations. Large power generators have lots of stored kinetic energy, or inertia, in their rotating mass, which helps stabilise grid frequency.
Renewable energy doesn’t provide the same degree of inertia, which means that rapid changes in frequency are likely, raising the chance of faults and blackouts in electricity supply.
£200m - £250m per year — That’s how much will need to be spent by 2020 on frequency response if the UK meets low carbon targets.
