How would the economy cope with electricity shortages?

There is an outside risk that the UK could face some limited short-term rationing of electricity this winter if weather conditions were to be unfavourable. This risk isn’t yet significant enough to factor into our forecasts. But if the supply of electricity to industry had to be cut by 10% for one whole quarter, that may reduce GDP by around 0.4% in that quarter. While not helpful, that wouldn’t be a disaster.
