The Seoul Metropolitan Government is reducing subway services to save energy amid threatened shortages in July and August. The subway will operate with just 919 trains in the two summer months, down from the current 1,050 trains.
The interval between trains will also increase by a minute or so between 10 a.m. and 5 p.m.
This is expected to save 11,500 kW of electricity.
Also, businesses will be fined up to W3 million (US$1=W1,128) if they leave the doors open while running the air conditioning and must not chill the temperature to less than 26 degrees Celsius.
After a grace period of one month in June, violators will be fined W500,000 for a first offence, W1 million for a second, W2 million for a third, and W3 million for every one beyond that.
Spot-checks will be carried out, particularly in busy shopping areas like Myeong-dong, Sinchon and Gangnam.
