LONDON Underground (LU) has launched a five-week trial of a new inverter system at Cloudesley Road substation on the Victoria Line, which enables energy returned to the grid by regenerative braking systems on trains to be reused at stations. LU says that in the first week of operation the system recovered enough electricity to power a large underground station such as Holborn for more than two days a week. Initial results indicate that up to 1MWh can be recaptured per day for reuse elsewhere. [From Richard Buckby]
