GE is governed by the Electricity (Guernsey) Law, 2001 (as amended) and is regulated by the Channel Islands Competition and Regulatory Authorities.
[6] GE has invested heavily in the Channel Islands Electricity Grid, using debt to finance the investment,[7] but losses in 2019 and 2020 as a result of the failure of the GJ1 cable requiring oil to be burnt for fuel, and the cost of the replacement GJ1, damaged finances.
[10] Estimated costs are:[11] The price paid by consumers is expected to rise until 2030, then gradually fall.
[11] In 1887 a dynamo was used to generate electricity for street lighting in front of Randalls Brewery in the Avenue, followed in 1897 by a water-powered first domestic installation at Le Chalet, Fermain Bay.
In February 1900 150 kW could be generated from the power station at Les Amballes, St Peter Port.
The quarry industry needed electricity for cranes, and in 1902 it was decided to build a second power station at St Sampson's; this took the generating capacity to 870 kW, with units supplied rising from 65,000 to 1.75m a year in 1910.
An explosion in November 1918 at the Vale power station left the road covered in debris.
In 1933 the States of Guernsey cancelled the concession and acquired the business at a cost of £285,500 at which time the capacity was 3.73 MW with 2,928 consumers on 165 kilometres (103 mi) of cables with eight substations.
[4]: 48 1934 saw the start of a 50 Hz 230 V AC supply, however some existing consumers took decades to change from DC.
Limited supplies of oil arrived on the island and generators were changed to run off town gas.
The Organisation Todt (OT) who were constructing defences in the island were required to arrange for the delivery of oil to generate the electricity they needed.
The OT built a power station to run off anthracite and coal in the Petit Bouet with a 720 kW capacity and using sea water for cooling.
Coal brought in by the Red Cross of the SS Vega in April allowed coke to be produced from which electricity could be generated for civilian use.
