Annual output of Marchwood power station, GWh.In the year 1980–81 the thermal efficiency was 20.77 per cent.

[13] Beginning in the early 1960s, a site next to the power station was the home of Marchwood Engineering Laboratories operated by the Central Electricity Generating Board.

The centre developed a broad-based research programme concentrating on structural, combustion and mechanical engineering, and included techniques, design codes, instrumentation and machines for welding, nuclear reactor inspection, turbines and other plant.

[14] Following privatisation of the electricity industry, Marchwood Engineering Laboratories were allocated to PowerGen, but that company was engaged in comparatively little research, and the rundown and closure of the site were announced in 1989.
