Power: Peak-period record

SHANGHAI'S daily power load hit a peak-period record of 23.8 gigawatts as the city baked under a relentless sun yesterday.

The figure was reached at 1:10pm, supplier Shanghai Electric Co said.

Thanks to a city government initiative, more than 5,200 local enterprises joined a staggered power-distribution scheme and reduced the total daily consumption by 820,000 kilowatts.

The company said the city was capable of supplying 24.3 gigawatts a day in peak periods.

If the heat continued, there was a chance the city may exceed its daily limit by 300,000 to 600,000 kilowatts, the power company said.

The city daily power-generating capacity stood at 15.6 gigawatts, and the company said it had secured 8.5 gigawatts of capacity from other provinces.

Though the amount is enough to meet this summer's peak demand, some generating capacity is typically held in reserve, and plants don't operate around the clock.

The city has several hot spots where industrial demand is heavy, and power cuts may be needed there, the company said.

The company has adopted a range of high-tech monitoring measures.

Some power grid improvements have been suspended because of construction for 2010 World Expo.
