To keep prices competitive, Washington diversifies its energy portfolio. The greatest contributor is hydroelectric power, which generates close to 7,700 gigawatts per hour (GWh) annually. Other significant sources of electricity are nuclear (812 GWh), natural gas (290 GWh) and coal (192 GWh). Renewables, which account for 912 GWh, include wind, solar and geothermal. As a result, the state offers electricity at a 35 percent discount from the national average.
It’s worth noting that you can switch for free with no exit fee 42-49 days before the end of your contract. Under Ofgem’s standards of conduct, energy firms have to give you between 42 and 49 days’ notice of your tariff ending. You can use this time to decide whether to stick with them, or switch. If you decide to switch, you won’t be charged an exit fee.
