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. : {$ D8 Z# `2 s: a4 v; l

"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. * D8 ]6 z- V9 m0 q0 E0 v. S5 U- z2 u1 N+ m. `: |* J+ U6 W8 v
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. # x" C( I6 \) ^! L( N& R0 H: Y# a3 p; R% F# U
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. # H p7 x. T4 t- m5 `/ D& 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. 9 }. c7 _8 p8 [8 _/ x

Beijing also use pricing leverage to try to level consumption, said Zhang, adding that factories would be encouraged operate outside peak power-usage hours. : J* H, l) D5 d$ m. M9 h9 u: A" z( A2 y- n. }) K7 ^
At peak hours, power costs 1.1 yuan (US$0.14) per kilowatt-hour, versus a lowest off-peak price of 0.26 yuan (US$0.03). 0 c: R4 F2 F. I5 m \$ R& U: B# X- _% W
"Such measures have greatly reduced the power consumption load in the city over the past two years," said Zhang, adding that a compensation system would be adopted for firms which voluntary adjust their consumption. 1 ?/ S6 C8 ~( S' f! F+ v
