FRIENDS of the Earth yesterday attacked the Government's policy on emergency electricity power-sharing between the two utility companies. The green group claimed the current restriction on what is known as interconnection in emergency cases artificially inflated electricity charges by up to 20 per cent. Hongkong Electric Company and China Light & Power have connections to share power in emergencies only. Friends of the Earth assistant director Plato Yip Kwong-to said the arrangement should be extended to normal peak hours so the power companies would not have to maintain high reserve power, whose costs were passed on to consumers. 'The Government is to blame because of its narrow and insufficient understanding of energy issues,' he said. The Government says new connections, costing about $468 million, will have to be built because the current arrangement is reserved for emergencies.
