Power prices remained near the highest in three years after the coldest temperatures since 1970 struck Tokyo.

Japan’s 24-hour average spot electricity price for delivery Jan. 26 slipped 0.8 percent to 18.11 yen per kilowatt hour, according to data from the Japan Electric Power Exchange compiled by Bloomberg. Prices in the previous session rose to the highest since Dec. 18, 2014.

The temperature in Tokyo fell to -4 degrees Celsius (24.8 degrees Fahrenheit) at 6:20 a.m. on Thursday, the coldest since January 1970, according to data from the Japan Meteorological Agency. The weather boosted demand for electricity for heating and Tokyo Electric Power Company Holdings Inc., known as Tepco, said it expects its reserve rate to fall to as low as 3.4 percent.
