During later construction work in 1912 the timbers of a Tudor warship believed to be Henry VII's 1488 ship Sovereign were uncovered on the site.

The 1924–28 station known as the low-pressure section had four Babcock & Wilcox boilers (decommissioned 1963) and 1 × 12.5 MW Fraser & Chalmers/GEC turbo-alternator which generated at 6.6 kV.

[3] The 1940–48 intermediate-pressure section had six Babcock & Wilcox boilers and 3 × 34.5 MW Fraser & Chalmers/GEC turbo-alternators generating at 22 kV.

The final 1952–57 high-pressure section had four John Thompson ‘La Mont’ boilers and 2 × 30 MW Fraser & Chalmers/GEC turbo-alternators generating at 22 kV.

The site of the main power station building then became the Waterfront Leisure Centre car park; part of the coaling jetty remains.
