The North Dock Power Station was commissioned and built in 1910. Originally it was coal fired but later, when it was converted, it became the only oil-fired power station in Wales and it had a capacity of 25 MW. The power station had 'Simple Impulse' type turbines plus a 'Compound Impulse' stage manufactured by British Thompson Houston Co. The demolition of the Power Station was carried out in 1972.
