London Hydro reports highest peak demand in 10 years

On Monday, London Hydro reported the highest recorded peak of demand for electricity because of an extended heat wave.

As the region faces an extended heat wave, London Hydro is reporting one of the summer’s first days of high electricity demand.

On Monday, London Hydro saw a peak demand of 716MW, the highest recorded peak in the last 10 years.

“Extreme heat can put added stress on the system, but thanks to strong planning and reliable infrastructure, London’s grid is performing well,” said Ysni Semsedini, CEO of London Hydro. “Our team continues to monitor demand in real time to ensure we can respond quickly if conditions change.”

An even higher demand is expected Tuesday as temperatures reach 33 C or 42 C with the humidex.

London Hydro’s peak electricity demand typically occurs between 4 p.m. and 6 p.m. when residential and commercial energy use overlap.

Despite the surge in usage, London Hydro reports the system is, “Stable and performing reliably.”

Tips to reduce energy

• Keep blinds and curtains closed during the hottest parts of the day
• Set thermostats a few degrees higher when home and even higher when away
