Supported green power plants
The renewable generating station accreditation notices issued by provincial governors are an important tool for forecasting green power trends. These notices have been used for the statistical analyses below.
At present accreditation notices are also issued by the provincial authorities for generating stations that have not yet entered service. This means that the notices are not a guide to installed capacity. Some of these plants will not be built despite the fact that they have been approved. The data below do not differentiate between stations supported under the Ökostromgesetz (Green Electricity Act) and those supported under provincial legislation.
You can also access the underlying data as a table.
E-Control’s statistics start in 2001 when renewable energy promotion was still a provincial responsibility, and the approaches taken to the classification of generating capacity by primary energy sources were correspondingly varied. Only with the inception of a nationwide renewable electricity support regime did standardised assignment to primary energy sources become possible. Thanks to adjustments using the statistics compiled by OeMAG and the green power balance responsible parties, variations in the attribution of capacity to energy sources can largely be ruled out, though shifts in classification remain a theoretical possibility.
Nevertheless, the information derived from the accreditation notices, which is supplemented by data reported by OeMAG, such as the number of generating stations under contract to OeMAG (or previously the green power balance responsible parties) and the capacity of each such plant, is sufficient for a reliable trend analysis.
Additional tools, such as regular questionnaires, surveys on a sample basis and expert interviews must also be used to reflect corrections, updates and documentation regarding amendments to notices.
