Hastings Power Station
Encyclopedia
Hastings Power Station was a gas turbine
power station
situated in Hastings
in East Sussex
, South East England
. Completed in 1966, the station had two 55-megawatt (MW) gas turbine generating sets. The first of the two sets was commissioned in January 1966, and the second in March of the same year.
The station consisted of a steel framed building clad with a 14 inches (355.6 mm) brick wall without windows. The access doors were doubled to reduce noise emission and the compressor intakes were at either end of the station at roof level. Silencing was provided at the air intake and by attenuators fitted between the exhaust gas ducting and the base of the two chimney stacks.
Chimneys
Exhaust gases entered the exhaust casing at 450 degrees Celsius (840 °F) and left the 200 ft high chimneys at 300 degrees Celsius (570 °F). The chimneys were concrete, lined with heat and acid resistant bricks and a stainless steel 'cap'. About 1.4 million cubic feet per minute (670 m3/s) of gas containing 19% oxygen was exhausted from each chimney at a velocity of about 135 ft/s (41.1 m/s; 92 mph).
Cooling water
Cooling water for the station auxiliaries and alternator was drawn from a 1000000 gallons (4,546.1 m³) pond, through a small independent mechanical draught tower.
Emergency generator
An emergency diesel generator exciter set was housed is a separate building. In the event of a system flux, the generator was capable of energising sufficient auxiliaries to start up and put on full load both main turbines consecutively.
Fuel oil
The gas turbine fuel oil supplies were held in five vertical main oil storage tanks, total capacity 4,440 tones, i.e., little more than 130 hours continuous generating at full load. Fuel was delivered by rail to the station's own siding located off the Hastings to Ashford Railway line, a few hundred metres north east of Ore Railway Station.
Rolls-Royce
gas generators were used. With little modification, they had been adapted to burn diesel oil with a high degree of reliability. They were developed from the well-tried aircraft engine used in the Comet
and Caravelle
aircraft
. It had a single shaft engine with a 17 stage axial flow compressor and canular combustion chamber before reaching the three stage turbine.
Turbine
There were two 55 MW AP4 Rolls-Royce/AEI sets. Four gas generators in 'box' formation powered a two stage turbine having discs of 2.5% nickel chrome and a stator of Nimonic
80A. The turbine blades were also forged from Nimonic 80A and were at the time, the largest Nimonic forging ever made.
Alternator
The alternator was designed to operate at 3,000 rpm and was coupled to the turbine via a clutch. The main and pilot exciters were gear driven from the end of the alternator shaft at 1,000 rpm.
This fast start-up of a power-station was particularly useful for supplying the national electricity gid at very short notice where sharp drops in supply occurred.

Automatic control
The station could theoretically be controlled from a remote location. The main turbines and auxiliaries were controlled with manual over-riding features. The main turbine sets could achieve a load of 10 MW from the pressing of a button within 2 minutes and 40 seconds. From the stabilising load of 10 MW, the fill capacity of 55 MW could be achieved in a matter of seconds.This fast start-up of a power-station was particularly useful for supplying the national electricity gid at very short notice where sharp drops in supply occurred.
