2190: 95:, mounted on a 308 m (1,010 ft) high earthed mast. In 1957 the transmission power was increased to 600 kW, in 1974 to 1,000 kW, and in 1981 to 2,000 kW. Transmission power was reduced to 1,000 kW during the hours of darkness. In 2011 the transmission power was reduced to 1,500 kW for cost savings. For the same reason the transmission power was reduced to 1,100 kW in 2017 and subsequently in February 2020 to 800 kW. 2184: 1965: 58: 1975: 140:
