Nelson power station supplied electricity to the town of Nelson, Lancashire and the surrounding area from 1892 to 1960. The power station was owned and operated by Nelson Corporation prior to the nationalisation of the British electricity supply industry in 1948. It was redeveloped in 1922 to 1925 to meet the increased demand for electricity.

History

In 1883 Nelson Corporation applied for a Provisional Order under the Electric Lighting Acts to generate and supply electricity to the town. This was granted by the Board of Trade and was confirmed by Parliament through the Electric Lighting Orders Confirmation (No. 4) Act 1883 (46 & 47  Vict. c. ccxvi). The power station was built in Charles Street, Nelson (53° 50′ 48″ N, 2° 12′ 28″ W) and it first supplied electricity in 1892. Further equipment was added to meet the rising demand for electricity; by the 1920s it had a generating capacity of 6,400 kW.

In 1900 a system was inaugurated by Nelson Corporation to generate electricity from domestic refuse.

From the system's establishment in February 1903 the power station supplied electric current to Nelson Corporation Tramways. The tram system was decommissioned in January 1934.

Nelson Corporation charged more for electricity than any other electricity undertaking in the North West. In 1913 Nelson Corporation charged 2.42 d./kWh, compared to Manchester Corporation which charge 1.02 d./kWh.

In 1928 Nelson power station became a 'selected' station in the North West England and North Wales Electricity Scheme. The Central Electricity Board imposed restrictions on the working and use of the station.

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

Nelson power station was decommissioned in about 1960. There is a 132 kV electricity sub-station on the site.

Equipment specification

In 1895 the plant comprised Willans engines coupled directly to Holmes and Siemens dynamos. The plant had a maximum load of 89 kW.

By 1922 the plant comprised boilers delivering 75,000 lb/h (9.44 kg/s) of steam to:

• 2 × 3,000 kW steam turbo-alternators AC
• 1 × 400 kW reciprocating engine with DC generator

These machines gave a total generating capacity of 6,400 kW comprising 6,000 kW of alternating current (AC) plus 400 kW of direct current (DC).

Electricity supplies available to consumers were:

• 400 & 230 Volts, 3-phase, 50 Hz AC
• 460 & 230 Volts DC
• 300 V DC Traction current

Plant in 1922–25

New plant was commissioned in 1922 to 1925. This comprised:

• Boilers:
  • 3 × Babcock & Wilcox 13,000 lb/h (1.64 kg/s) water tube boilers, steam conditions were 200 psi and 600 °F (13.8 bar, 315 °C)
  • 1 × Babcock & Wilcox 20,000 lb/h (2.52 kg/s) water tube boiler, steam conditions as above,
  • There was therefore a total steam raising capability of 59,000 lb/h (7.43 kg/s), steam was supplied to:
• Generators:
  • 1 × 3 MW Brush-Ljungstrom turbo-alternator
  • 1 × 3.3 MW Brush-Ljungstrom turbo-alternator
  • 1 × 6.45 MW Brush-Ljungstrom turbo-alternator

The total generating capacity was 12.75 MW  at 6.6 kV.

Condenser cooling water was drawn from the nearby Leeds and Liverpool canal.
