CHINA Light and Power is attempting to introduce the Scheme of Control concept to its proposed power plant in Shandong province. Managing director Ross Sayers yesterday confirmed that the concept of Scheme of Control was part of the discussions between China Light and the Shandong authorities. China Light signed a letter of intent with the Shandong Electric Power Company to carry out a feasibility study on the possible joint development of power station projects in Shandong. The study is due to be completed in mid-1994. ''At that time, and only at that time, will we be able to determine if the Shandong project is commercially viable,'' Mr Sayers said. He said the project was on track but it might not be until later in 1994 that China Light could determine whether this was a good project for the company's shareholders. A Scheme of Control system, modelled on the one in use in Hong Kong, is expected to provide a guaranteed profit and return on investment. Under the Scheme of Control agreement in Hong Kong, China Light is entitled to a 15 per cent return on average fixed assets employed. Commenting on China's recent efforts to slow economic growth, Mr Sayers said it was a desirable policy on the whole but demand for electricity would be affected. ''It is inevitable that that will slow the demand for electricity in Guangdong and also the provision of foreign exchange,'' he said. ''But this is something we obviously work closely on with GGPC (Guangdong General Power Company) people to maximise the available sales for China Light.'' He added that sales to China would still record a substantial growth this year. Sales to China for the nine months to June 30 increased by 58.7 per cent compared to the same period last year. In the longer term, Mr Sayers said China Light's sales to China would decline as generating capacity came on stream in Guangdong. ''But I also believe China Light will be selling electricity to China for quite some long period of time,'' he said.
