Heat leads to record-high elec­tric­ity use: Taipower

The China Post - - LOCAL - BY ENRU LIN

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.
