Electric power industry The world's first public electricity supply was provided in late 1881, when the streets of the Surrey town of Godalming in the UK were lit with electric light. This system was powered from a water wheel on the River Wey, which drove a Siemens alternator that supplied a number of arc lamps within the town. This supply scheme also provided electricity to a number of shops and premises to light 34 incandescent Swan light bulbs. Additionally, Robert Hammond, in December 1881, demonstrated the new electric light in the Sussex town of Brighton in the UK for a trial period. The
Electricity billing in the UK is in units of pence / MPAN / day. New DUoS charges will come into effect on 1 April 2018 under a proposal known as DCP228.

Exempt supplies include domestic supplies and supplies using less than the "de minimis" threshold of 1,000 kWh / month. Suppliers meet the Renewables Obligation by submitting a certain number of Renewable Obligation Certificates (ROCs) each year to Ofgem, which demonstrates that the certified electricity has come from a renewable source.
