Feed-in Tariffs
Reduce your electricity and heating bills with solar power and hot water. Contact your renewable energy specialist Wight Energy Ltd for details on how you can benefit.
The Government's feed-in tariff is targeted at consumers using renewable energy systems. It obligates utility companies to pay a set rate for the unit of electricity generated by their system.
The rate for a retrofit PV system is 21p for a term of 25 years. The income is tax free. The rates are also index-linked for inflation. Surplus electricity exported back to the grid can be sold for a minimum of 3.1p per kWh.
Electricity prices are universally expected to rise at an increasing rate. That's good news for consumers concerned about when the system will pay for itself. Between May 2006 and June 2008 single rate electricity prices for the first 125KwH used rose on average 64%. For subsequent consumption, prices rose on average by 30%.
