INTRODUCING THE HOUSEHOLD ENERGY PRICE INDEX  

At the end of 2009, to correct for a persistent lack of current, frequently updated and methodologically reliable   information on household prices for both electricity and gas at the European level, the Austrian regulator   Energie-Control Austria and VaasaETT developed a methodology that would help monitor residential energy prices.  The results, updated monthly, are made available on our respective websites and sent to over 100 subscribers from regulatory or government bodies, utilities, research centres, consultancies and others across the globe.

Based on the electricity and natural gas prices collected both for incumbents and competitor companies and taking into account different local consumption patterns, Energie-Control Austria and VaasaETT compile and publish the Household Energy Price Index (HEPI) as well as a monthly ranking of prices within the EU-15 capital cities.  The methodology is designed in such a way that “HEPI prices” reflect prices paid by local typical residential customers and assess overall price developments in Europe.  It does so by aggregating the tariffs offered by the main players in each city according to their respective market shares.  Data is collected directly from utilities and authorities in the respective markets using a thorough, precise and comparative definition. HEPI is Europe’s only independent comparative monthly index of electricity and gas prices across the EU-15 states.
