cation (3 W/m2). The steady power of the lagoon system would be more
valuable than the intermittent and less-flexible power from the ordinary
A two-basin system could also function as a pumped-storage facility.
311Efficiency of 90%... Turbines are about 90% efficient for heads of 3.7 m or
more. Baker et al. (2006).
320Getting “always-on” tidal power by using two basins. There is a two-basin
tidal power plant at Haishan, Maoyan Island, China. A single generator
located between the two basins, as shown in figure G.12(a), delivers power
continuously, and generates 39 kW on average. [ ].
