Korea Power Exchange concerned that record power usage in June could result in demand exceeding reserve capacity supply Updated: 2022-07-04 19:02:58 KST

The summer heat wave that began last month in Korea has already caused record-high electricity demand.
Some experts fear demand could exceed supply and result in the first power alerts since 2013.
Shin Se-byuck provides a deeper analysis.

The summer heat wave began last month has sent electricity demands to all-time highs.

According to the Korea Power Exchange, maximum power usage in June reached an average of 71,805 megawatts, up 4.3 percent from the same month last year.

This figure is the highest average since data were first compiled in 2005.

the first time in June that demand has exceeded 70-thousand megawatts.

The scorching hot weather in Korea prompted the government on Saturday to issue this year's first nationwide heatwave alert 18 days earlier than last summer.

Homes and offices have been using more air conditioning, which is sapping the country's electricity reserves.
On June 23rd, the electricity reserve ratio fell to 9.5 percent, the first time this year it's been below 10 percent, which is the ratio needed to ensure stable power supplies and be prepared for emergencies.

With electricity demand to rise even higher in July and August, analysts have expressed concern that a supply warning may have to be issued this summer for the first time in nine years.

That would mean limiting air-conditioning in public sector buildings and recommending people not to use too much electricity at peak hours.
These measures would be taken once power reserves fall to a certain level, which the Energy Ministry has said could happen in the second week of August at the peak of the summer heat.
