History

At the beginning of the twentieth century, the use of electricity for general purposes began to be considered, and the Newcastle upon Tyne Electric Supply Company (NESCo) realised the potential it offered for development. In June 1899, the Walker and Wallsend Union Gas Company (WWUGC) acquired Parliamentary powers for the supply of electricity to the area around Wallsend

. In October 1900, NESCo acquired the entire power station from the WWUGC, with the exception of the cables and sub-station machinery installed for the purpose of supplying the works in the area in which the WWUGC had obtained Parliamentary powers. the WWUGC continued to buy electricity in bulk from NESCo.

The station was officially opened on 18 June 1901 by Lord Kelvin. At the opening he said:

"We have seen at work what many have not seen before - a system realised in which a central station generates power by steam engines and delivers electricity to consumers at distances varying, I think, from a quarter of a mile to over three and a half miles... A larger station is in prospect, larger work is contemplated. This admirable but comparatively small station at Neptune Bank makes a splendid beginning... What I am seeing today is the dream of my life realised. I do not know the limits of electricity, but it will go beyond anything we can conceive of today."


The station was the first power station to generate electricity for industrial purposes, rather than just for domestic and street lighting, and this led to a rapid expansion of NESCo.

NESCo laid high-tension cables from the power station to various substations

congradutalted NESCo in June 1901, stating that "not merely electric power supply on Tyneside was formally inaugurated last Tuesday, but the era of electric power utilisation all over the kingdom."

A year after the station came into operation, NESCo's original power station at Pandon Dene was closed and converted into a substation. The Pandon Dene station had originally supplied Newcastle city centre with electricity, but the new Neptune Bank station took over this supply, transmitting using high voltage cables laid in ducts, rendering the older station obsolete.

Design and specification

The station was the first major design project of Charles Merz, of the Merz & McLellan

The station's buildings were built from corrugated iron, and the boiler house adjoined the engine room on its south facing side. Each of these two buildings measured 100 feet (30.5 m) by 52 feet (15.8 m). To the north east of the main station buildings lay the station's cooling pond

 which was 60 feet (18.3 m) below the level of the station. The station was also equipped with a testing pond, capable of absorbing up to 1,500 kW.

Coal was delivered to the station via the NER's North Tyneside Loop. An electric locomotive was used to convey the coal from the railway to the boiler house. The station's boiler house was equipped with four batteries of two Babcock & Wilcox boilers. Each boiler had a capacity of 1,000 horsepower and a working pressure of 200 psi. Each was fitted with superheaters and mechanical stokers and had a heating surface of 4,020 square feet, with a superheat of 100 - 120 degrees Farenheit. Each could evaporate 14,000 pounds of water per hour. Ash waste from the boilers was discharged into trucks.

s, supplying current to motor-generators and transformers in the substations attached to the distribution network. The motor-generators in the substations provided DC from the supplied AC and the transformers stepped-down the 6,000 V supply to 200 V for lighting use and 400 V for industrial use.

By 1904, there were a total of nine different generating sets operating at the power station. Sets No. 1 and 2 were DC generators driven by 300 HP two-crank compound engines running at 380 RPM, power from which supplied DC network in Wallsend and Walker. Set No. 3 was a 50 kW set used for exciting purposes only. Sets No. 4 and 5 were used as balancers and motor generators and had a combined capacity of 150 kW. Sets No. 6, 7, 8 and 9 were each driven by 1,400 HP engines and in turn each drove a 750 kW alternator. The two Parsons sets worked alongside these.

Operations

Coal was delivered to Neptune Bank from the Riverside Branch of the North Eastern Railway at Tyne Pontoons signal box, about halfway between Walker and Carville stations. It was taken to the station's railway sidings using a small electric locomotive and unloaded in front of the boiler house. It was then hand-loaded into automatic stokers which fired the boilers. Removal of ash from the boilers was performed by machine.The station was badly located for sources of cooling and boiler water - it was some 60 feet above the level of the nearby River Tyne, which was also 200 feet away. The concept of a cooling tower

 had not yet been invented and a large but inefficient brick-built cooling pond was used.

Closure

Following Neptune Bank's commissioning there was a rapid increase in the demand for electricity, which couldn't be met by the station, and so in 1904 NESCo commissioned Carville Power Station
