Is switching off hot water tanks at midday effective in saving energy?

Thanks to Linky

“One month after the implementation of this energy sobriety measure, Enedis has observed a smoothing of electricity consumption peaks in the middle of the day, saving 2.4 gigawatts (GW), the equivalent of the consumption of a city like Paris” at the time of the peak. “It’s considerable”, welcomed on France Bleu the operations and systems manager at Enedis, Thierry Sudret, speaking of “a great success” close to the expected 2.5 GW.

This temporary system, in force since October 15, consists of staggering the heating of the balloons, generally carried out between 12 p.m. and 2 p.m., to switch it over during the night and thus avoid peaks in electricity consumption during the meridian break.

It was triggered by Enedis via its Linky smart meters, at the request of RTE (the high voltage line manager) and the public authorities. “It now contributes to the essential maintenance of the electricity supply-demand balance ensured by RTE in order to avoid having to resort to temporary cuts”, specified Enedis.

Until April 15

Validated by the State after a ministerial decree of September 22, this measure will be applied until April 15. It concerns 4.3 million customers in France “who have subscribed to a full-hour off-peak contract including off-peak hours from 12 p.m. to 2 p.m. “Enedis also specifies that this measure “will have no impact on the bill of the customers concerned, the off-peak rate being maintained. This device is almost painless for individuals and artisans.
