After the weather report and between other programmes, information about the load on the power grid would be broadcast using green, yellow and red symbols to show how much power is available.
The government hoped to reach around 80 per cent of the public.
Information on the expected load on the French grid was also available from national grid provider RTE which posted the data online.
A green symbol meant the nation’s electricity use was in balance, while yellow indicated some strain.
Red meant there might be supply interruptions and at that level, people would be asked to reduce their consumption between the hours of 8.00 a.m. and 12.00 p.m.
An example was by using their washing machines or ovens at another point during the day.
People were not being asked to stop watching television.

France had put a coal-fired power plant in north-eastern Saint-Avold back into operation given the energy crisis.
