Deptford: cradle of power generation

Think of power stations in London, and you probably think of the iconic Battersea towers; the reborn Bankside, now Tate Modern; maybe Lots Road or, if you focus on south-east London, Greenwich. However, there's a glaring omission from this list, perhaps because few traces of it remain.


Deptford Power Station was the world's first large-scale electricity operation. Sebastian de Ferranti, pioneering chief engineer of the London Electric Supply Corporation and the man who established the principle of a national grid using alternating currents, designed and built it.

The station was located on a three-acre site which had previously contained East India Company storage sheds. It was designed to house four 10,000-horsepower engines and 500-ton alternators, enough to supply 2 million lamps. Unfortunately, the planned Deptford Power Station was going to be too effective: during its construction, the Board of Trade decided to limit its area of supply and allow competitors, while technical problems meant delays which lost the company many customers. Its capacity was drastically scaled down when it opened in 1889; frustrated, Ferranti left the company in 1891.

However, the company went on to attract more customers and when the London Electricity Supply Corporation later merged with nine other companies to become the London Power Company, they built a new station on the Deptford site. Construction in 1926 proceeded quickly, despite tragedy when a shaft ring fractured, killing five men. Following nationalisation in 1948, a high-pressure extension was built and the power station became Britain’s second-largest. Throughout its operation, the station received coal supplies by river to its own jetty. However, the Ferranti building was taken out of use in 1957 and demolished in the 1960s. The other buildings were closed in 1983 and demolished in 1992 - click here and here for photos.

The power station and its creator are now commemorated locally by the Ferranti Park, opened opposite the Laban Centre on 19 June 2004. The power station's jetty also remains, rotting quietly in the River Thames.
