Leeds (Whitehall Road) power station

Leeds power station, also known as Whitehall Road power station, supplied electricity to the city of Leeds and the surrounding area from 1893 to 1965. It was initially built, owned and operated by the Yorkshire House-to-House Electricity Company Limited. Leeds Corporation took over the electricity undertaking in 1898 and generated and distributed electricity until the nationalisation of the British electricity supply industry in 1948. The power station was redeveloped several times to meet increasing demand for electricity.

History

edit

Leeds town council had conducted experiments with electric lighting in the mid-1880s.[1] The council had rejected a proposal in 1889 to provide electricity to the public as being too speculative.[1] The Yorkshire House-to-House Electricity Company Limited (registered on 26 June 1889)[2] applied for a Provisional Order under the Electric Lighting Acts to generate and supply electricity to the city. This was granted by the Board of Trade and was confirmed by Parliament through the Electric Lighting Orders Confirmation (No. 12) Act 1891 (54 & 55 Vict. c. cvi).[3] The company established a successful electricity supply system including a power station at Whitehall Road (53°47'43"N 1°33'07"W).[4] Electricity was first supplied in May 1893. In 1898 Leeds Corporation resolved to purchase the undertaking under Clause 59 of the Company’s Provisional Order. The purchase price offer was 40 percent above the cost of the Company’s system, and the transfer of ownership took place in 1898.[1]

Equipment specification

edit

Plant in 1898

edit

The original plant at Leeds power station comprised compound and vertical condensing engines coupled directly and by ropes to Lowrie-Parker and Hall dynamos, and Ferranti and ECC alternators.[2] In 1898 the generating capacity was 1,500 kW and the maximum load was 1,010 kW.[2]

Plant in 1923

edit

By 1923 the generating plant comprised:[5]

  • Coal-fired boilers generating up to 996,800 lb/h (126 kg/s) of steam, which was supplied to:
  • Generators:
    • 2 × 3,000 kW steam turbo-alternators
    • 3 × 6,000 kW steam turbo-alternators
    • 2 × 7,500 kW steam turbo-alternators
    • 1 × 12,000 kW steam turbo-alternator

These machines gave a total generating capacity of 51 MW of alternating current.[5]

The electricity supply available to consumers was:

  • 2- phase, 50 Hz AC at 100, 200 and 400 Volts
  • 3-phase, 50 Hz AC at 346 and 200 Volts.[6]

Plant in 1955

edit

By 1955 the plant at Whitehall Road comprised:[6]

  • Boilers:
    • 14 × Babcock & Wilcox  boilers with chain  grate stokers and a total capacity of 480,000  lb/h (60.5 kg/s), steam conditions 185 psi and 550°F (12.8 bar, 288°C), supplied to:
  • Turbo-alternators:

The total installed generating capacity was 37 MW.

Condenser cooling water was drawn from the adjacent River Aire.[6]

Operations

edit

In 1898 the amount of electricity sold to the 576 consumers was 833,280 kWh. There was estimated to be the equivalent of 49,150 (8 candle power) lamps on the circuits.[2]

Operating data 1921–23

edit

The operating data for the period 1921–23 was:[5]

Under the terms of the Electricity (Supply) Act 1926 (16 & 17 Geo. 5 c. 51)[7] the Central Electricity Board (CEB) was established in 1926.[8] The CEB identified high efficiency ‘selected’ power stations that would supply electricity most effectively; Leeds was designated a selected station. The CEB also constructed the national grid (1927–33) to connect power stations within a region.

Operating data 1946

Leeds power station operating data in 1946 was:[9]

Nationalisation

edit

The British electricity supply industry was nationalised in 1948 under the provisions of the Electricity Act 1947 (10 & 11 Geo. 6 c. 54).[10] The Leeds electricity undertaking was abolished, ownership of Leeds power station was vested in the British Electricity Authority, and subsequently the Central Electricity Authority and the Central Electricity Generating Board (CEGB).[8] At the same time the electricity distribution and sales responsibilities of the Leeds electricity undertaking were transferred to the Yorkshire Electricity Board (YEB).

Operating data 1954–63

Operating data for the period 1954–63 was:[6] [11]

Leeds was an electricity supply district, covering 87 square miles (225 km2) and including the city and county borough of Leeds, the borough of Morley and part of the district of Rothwell with a total population of 562,000 in 1958.[6] The number of consumers and electricity sold in the Leeds district was:[6]

Year 1956 1957 1958
Number of consumers 192,355 194,119 196,743
Electricity sold GWh 631,297 665,873 196,743

Closure

edit

Leeds (Whitehall Road) power station was decommissioned in the late 1960s.[12] The buildings were subsequently used as a CEGB training centre for many years until final closure. The building has been demolished and the area has been redeveloped with commercial premises.
