BEIJING, May 31 -- Beijing will not impose compulsory brownouts or power-downs for factories this summer despite a predicted energy shortage, a senior city official said yesterday. 8 M/ |4 `7 j: b4 a
+ k$ h; V: d2 Y$ d. m "Peak power consumption is expected to top 12.2 million kilowatts, or 14.6 per cent higher than last year," said Zhang Gong, vice-director of the Beijing Development and Reform Commission. $ J) K, G& Z4 v( S8 n7 s( ~. D

Speaking at a press conference Zhang said the electricity shortage during peak periods this summer could reach 5 million kilowatts, or even 7.3 million kilowatts in some parts of the capital. 9 T( Q, n( o" M2 x- ]. Z, V' u5 z3 e" \1 ~/ S& x, g8 F
Limited power generation, slow grid construction, a rapid increase in consumption, skyrocketing prices for coal and hydro-electric power and uncertain weather will create a sharp contradiction between demand and supply, Zhang warned. $ @# a) P% `5 i! h 1 z2 z1 l* K, z To deal with the shortage, Beijing's local government will shift from administrative control measures to a long-term technology-oriented plan, said the official. !
