 In 1989, Blyth A won a place in the Guinness Book of Records by setting the world record for total running hours in a plant of its size, when all four generating units achieved 200,000 running hours. With the privatisation of the UK's electricity supply industry in 1990, the station passed into the ownership of National Power. In 1991, the two 275 MW units at Blyth B (units 5 & 6) were decommissioned on the grounds of economy, despite the station having been modernised in the early 1980s. This decommissioning resulted in 260 job losses.
