County of Durham Electrical Power Distribution Co
1899 Company incorporated to supply lighting and power in the County of Durham.
1900 The County of Durham Electric Supply Co was incorporated to supply authorised users in bulk with electricity as well as individual users; its shares were held by the Distribution Co[1]
1905 The company had been under control from London by the British Electric Traction Co since its formation but the board had recently been reorganised to bring it more under local control with Dr John Theodore Merz as chairman[2]
1905 Powers to operate the company's generating stations at Jarrow and Durham City were transferred to the Newcastle-upon-Tyne Electric Supply Co[3]
1907 The company and its subsidiary were taking all of their electricity from the Newcastle-upon-Tyne Electric Supply Co
1908 The company was chiefly concerned with supplying electricity on the south side of the Tyne and the County of Durham; they had an agreement with the Newcastle-upon-Tyne Electric Supply Co to receive bulk supplies from the Carville Power Station; a tunnel was being driven under the river to carry cables from Carville to the 6,000hp station at Hebburn on the south side. The Newcastle company had acquired land at Dunston on which it would build a power station that would supply 30,000 hp to the Durham company and other purposes, as well as supply areas around the higher part of the river as well as the rest of the County of Durham.[4]
1932 One of eight companies absorbed by the Newcastle-upon-Tyne Electric Supply Co[5]
