Bury power stations are two generating stations that supplied electricity to the town of Bury, Lancashire and the surrounding area from 1896 to 1970. They were owned and operated by Bury Corporation until the nationalisation of the British electricity supply industry in 1948. The power stations were rebuilt several times to replace older plant and to meet an increasing demand for electricity.
In 1890 Bury 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. 3) Act 1890 (54 & 55 Vict. c. clxxxviii).[1] The corporation built a power station in Rochdale Road, Bury (53°35'39"N 2°17'19"W),[2] from which the supply of electricity started on 5 November 1896.[3]
The demand for electricity increased and a new larger generating station at Chamber Hall, Bury (53°35'51"N 2°17'57"W)[4] was authorised in 1908. Construction started in 1909 and the first electricity was supplied from the new station in August 1911.[5]
The original plant at Rochdale Road power station comprised Belliss engines coupled directly to Siemens dynamos, in 1898 the total capacity of the plant was 304 kW.
In 1923 the generating plant at Rochdale Road power station comprised:[6]
These machines gave a total output of 1,500 kW of direct current.
Electricity supplies to consumers were at 440 and 220 Volts DC, DC traction supply was provided to the Bury Corporation tramways from its inception in 1903.
By 1923 the plant at Chamber Hall comprised:
These machines gave a total output of 13,000 kW of alternating current.
Customers were supplied with 3-phase, 50 Hz AC at 400 and 230 Volts.
Further turbo-alternators were installed in 1924 (10 MW) and 1930 (10MW).
In 1954 the plant at Chamber Hall power station comprised:
The installed capacity Chamber Hall was 26 MW with an output capacity of 16 MW.
Condenser cooling water was drawn from the nearby River Irwell and was cooled in two Peter Brotherhood wooden towers each with a capacity of 250,000 gallons/h (0.32 m3/s) and with a cooling range of 20°F (11.1 °C).
Coal was supplied through a dedicated branch siding from the adjacent railway line.
The final user supply from Rochdale Road and Chamber Hall stations for the period 1921–23 was:

Rochdale Road station was operational in 1923 but was decommissioned sometime later. This may have been when one of the 10 MW machines was installed at Chamber Hall in 1924 and 1930, or when the trams started to be withdrawn from 1932. The station it does not appear on a map dated 1937.[7]

The British electricity supply industry was nationalised in 1948 under the provisions of the Electricity Act 1947 (10 & 11 Geo. 6 c. 54).[9] The Bury electricity undertaking was abolished, ownership of Bury power station was vested in the British Electricity Authority, and subsequently the Central Electricity Authority and the Central Electricity Generating Board (CEGB).[10] At the same time the electricity distribution and sales responsibilities of the Bury electricity undertaking were transferred to the North Western Electricity Board (NORWEB).
Operating data for the period 1954–67 was:[11] [12]

Following nationalisation the Bury electricity supply district was created. This covered an area of 41 square miles (106 square km) and included the County Borough of Bury, the boroughs of Heywood and Radcliffe, and the districts of Kearsley, Little Lever, Ramsbottom, Tottington and Whitefield. It served a population of 103,000 (1958). The number of consumers and electricity sold was:
| Year | 1956 | 1957 | 1958 | |
| Number of consumers | 36,925 | 37,477 | 37,813 | |
| Electricity sold MWh | 178,996 | 183,203 | 203,073 |

Bury power station was decommissioned in about 1970.[13] The buildings were subsequently demolished.
