§ Mr. Gareth Wardell
asked the Secretary of State for Energy if he will publish in the Official Report such details as he has of the tidal electricity generating scheme at Jangxia in China.
§ Mr. Giles Shaw
According to information supplied by the Senior Engineer of the Department of Hydraulics in Peking, construction at the tidal site at Jiangxia began in 1972. It is intended to be an experimental site and part of a programme of studies of larger schemes. The first turbine generator was commissioned in 1980 and the second a few months ago. A total of six is intended, each consisting of a bulb type turbine 2.5 metres in diameter with a generator rated at 500 kw. All equipment is made in China. The barrage is designed for two way operation generating on both the ebb and flood tides. The closure is some 700 metres across and the machinery is built in situ upon an existing rock foundation.
