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 sector in Guyana respectively own generators which supply them with 64%, 54% and 31% respectively of the total electricity consumed. A side effect of self-supply of energy is that the corporate demand for electricity in some regions of the country has decreased significantly. While private generation temporarily eases the pressures on the overall capacity for the sector, it also prevents the realization of economies of scale at a system level. Self-provision of energy appears more costly to companies (up to US$0.38 per KWh) than regional and even local tariffs (around US$0.22 and US$0.25 respectively on average).
