There are big differences in the price domestic consumers pay for gas and electricity depending on which of the 15 European member states a customer lives.

Electricity customers in Copenhagen pay the highest price for electricity at €0.3088/kWh, while those in Athens pay just €0.1143/kWh according to the Household Electricity Price Index for Europe (HEPI), launched today by the Austrian Energy Regulator (E-Control) in collaboration with energy think-tank VassaETT.

The difference results from much higher energy taxes in Denmark, which make up the majority of the energy price. Customers in Helsinki and Athens pay the least.

For gas, customers in Stockholm pay the most at €0.1372/kWh, while those in London pay the least at €0.0426/kWh.

The index also showed that household end-user prices for both gas and electricity have fallen since January 2009 as the result of lower wholesale prices.
