Neasden Power Station was a coal-fired power station built by the Metropolitan Railway for its electrification project. It was opened in December 1904. It was within the site of the current London Underground Neasden Depot.

The station was commissioned in 1904 with three British Westinghouse turbo-generators rated at 3,500 kW each. Two 5,000 kW sets were added five years later. The station was further upgraded in 1912 when the original turbines were replaced. [1]

Along with Lots Road Power Station and Greenwich power station, Neasden power station supplied the whole London Passenger Transport Board network from its formation in 1933.

Coal for the power station was brought in by trains, initially by the Metropolitan Railway using its fleet of steam locomotives, from June 1935 by the London & North Eastern Railway, and from 1948 British Rail.

By 1957 the plant comprised eleven boilers, five were chain grate stokers and six were heavy fuel oil. The total evaporative capacity was 880,000 lb/hr (111 kg/s). These supplied 3 × 20 MW, 1 × 16.5 MW and 1 × 13.2 MW generating sets, a total capacity of 89.7 MW. Electricity was generated at 11 kV, 33.33 Hz. [2]

Condenser cooling was undertaken in nine wooden cooling towers, their cooling capacity was 2.627 million gallons per hour (0.33 m3/s). [2]

The power station ceased generating in 1968.

Stonebridge Park power station

Stonebridge Park power station (51° 32’ 51” N 0° 17’ 06” W) was located about 1 mile south west of the Neasden power station. It was built in 1912–4 by the London and North Western Railway to supply electricity to the Watford DC lines. It was subsequently owned by the London, Midland and Scottish Railway (1923 – 1949). By 1957 it was owned and operated by the London Midland Region of the British Transport Commission. It had five chain grate boilers with a total evaporative capacity of 315,000 lb/hr (40.0 kg/s). These supplied steam to 1 × 20 MW, 1 × 18 MW, 1 × 0.2 MW generating sets. Electricity was generated at 11 kV, 50 Hz. The maximum load was 27 MW. [2]

Condenser cooling was undertaken in one concrete and eight wooden cooling towers, their cooling capacity was 3.5 million gallons per hour (0.442 m3/s). [2]

Stonebridge Park power station closed in 1967.
