Heat leads to record-high electricity use: Taipower
Intense heat led to record-high electricity use yesterday afternoon, according to the state-owned utility Taiwan Power Company (Taipower, ).
National power use topped out yesterday at 2:02:57 p.m., when the company supplied 32,864.6 megawatts (MW), the most it has been asked to deliver this year so far, the company said.
The electricity reserve margin — or the generating capacity available to meet short-term emergency demand — was thin yesterday at 7.38 percent.
Tuesday marks the fourth time this month that national electricity use has reached an annual high: Taipower’s meters hit records first on June 2, then on June 3 and again on June 5.
Power consumption in Taiwan typically reaches its annual high in July or August, according to Taipower’s records.
The utility’s all- time power delivery peak was logged at 1:40 p.m. on July 15 of last year, when the demand reached 34,990.2 MW and sent operating reserves down to 5.1 percent — their lowest in five years.
The operating reserve margin dipped to 7.38 percent yesterday, which warrants a moderate-risk “yellow” alert that warns of a tight supply, Taipower said.
A margin of 6 percent or below, according to Taipower’s benchmark, triggers an “amber” alert that signals an alarmingly tight supply and chance of rationing.
To maintain reserve capacity above 4 percent through the summer, Taipower has postponed maintenance on generators at Mingtan Power Station (
Dry Heat to Stay: CWB
Across Taiwan, daytime temperatures had soared to between 32 and 35 degrees Celsius yesterday, according to the Central Weather Bureau (CWB, ).
CWB’s Weather Forecast Center ( ) director Cheng Mingdean ( ) said Taiwan is set to see dry hot days until mid-June, despite the onset of plum rain season.
The first of the plum rains arrived May 1 and continued throughout the month, providing relief to one of the worst droughts in Taiwan history.
A dry spell hit Taiwan since early June and is expected to stay until mid-June, Cheng said yesterday.
