Output is the amount of electricity produced by our fleet of power stations. Output for the year was 58.4TWh, the same as last year. Output in the year was adversely affected by the Boiler Closure Unit issue at Hartlepool and Heysham 1 and the boiler temperature restrictions at Hinkley Point B and Hunterston B, offset by a significant improvement in the level of small unplanned losses and higher output from our coal-fired power station, Eggborough.
