Wholesale electricity prices
The price that we pay for electricity is largely dictated by wholesale electricity prices. As 40% of UK electricity coming from gas-fuelled power stations, wholesale electricity prices are in turn directly affected by the wholesale price of gas.
In 2002, wholesale gas prices began to rise at an unprecedented rate. As the world economy has grown, demand has pushed wholesale gas prices through the roof. The UK’s North Sea fields have declined faster than predicted, so the UK has been forced to import more gas from Europe. At the same time, the price of oil has risen massively, which has also driven up wholesale gas prices.
This is a good consideration to find cheap gas, electricity and energy prices.
