The roots of Dorchester's electricity come from its current distribution network operator SSE. Before privatisation in 1990, the electricity was provided by regional electricity board 'Southern Electricity Board'. Thereafter it continued as a plc company and merged with 'Scottish Hydro Electric plc'. This became 'Scottish & Southern Energy', the company we now know today as SSE.


Dorchester used to recieve its gas supply from 'Southern Gas Board' until, like the rest of the regional gas boards, it became a part of the British Gas Corporation.
