MOUCHEL Asia has won the consultancy contract for civil works development at the Black Point Power Station. The $22 billion power plant near Tuen Mun will supply electricity to Kowloon and the New Territories. Mouchel's cut of the $2.5 billion civil works portion is not known. The company's project director, Mr Tim Ingram, said: ''Without doubt, Black Point will rank as the largest, most economical and modern generating power station in the world. It is one of the projects of the decade, and possibly even of the next.'' The project, undertaken by Castle Peak Power Co - a 60-40 joint venture between Exxon Energy and China Light and Power - is the biggest of its kind. Natural gas will be piped 800 kilometres under the South China Sea from Hainan Island to Black Point under a separate contract. The Hongkong-based practice, part of an international group, has worked with CLP for more than 15 years and was responsible for the 4,350-megawatt Castle Peak A and B coal-fired power stations. It won the Black Point contract against competition from consultants from the UK, Hongkong and North America.
