Data published comprise average prices and taxes of the most important energy products consumed by the industry as well the private sector. Surveys conducted by Statistics Austria – such as the material input statistics – are an important basis for the published data. Apart from Statistics Austria, the Federal Ministry of Economy, Energy and Tourism (oil products) and E-Control (electricity and natural gas) also collect price and tax data which are used for the compilation of the statistics. Preliminary data for the previous year are published in March, final data in December.
