German EEG levy decreases slightly


The German Renewable Energy Sources Act (“Erneuerbare Energien Gesetz”, EEG) is a series of German legislative acts providing a scheme for the feed-in tariff of electricity from renewable sources in order to encourage the generation of green energy. The so called “EEG-Umlage” (EEG levy) is a surcharge to the price of each kWh which is paid by non-privileged end consumers to promote the renewables. The levy is calculated on the difference between feed-in tariffs and the sale of renewable energy at the European Energy Exchange.

Today, TSC members 50Hertz, Amprion, TenneT, and TransnetBW, the four German transmission system operators (TSOs), have published the new EEG levy for 2018, which decreases slightly by 1.3% to €0.06792 per kWh (€0.06880 in 2017). The reason for this is a predicted increase of feed-in of renewable electricity by almost 17TWh to about 204TWh, caused primarily by the expansion of wind energy, on- and offshore.

Together with the EEG levy, the four German TSOs have presented the EEG medium-term forecast (“EEG-Vorschau”). This document includes the likely development of the renewable’s feed-in for the next five years. By the year 2022, the TSOs expect the total installed renewable capacity under the EEG law to reach 135GW, while the overall net electricity demand is assumed to diminish to nearly 511TWh.

MRA tool introduced


TSCNET Services has developed an easy-to-handle tool to facilitate the cost-sharing process of so-called Multilateral Remedial Actions (MRAs). The first version of the subtle MRA tool (MRAT) has been launched successfully, with Martin Mach in charge, one of the Data Quality Managers at Team Operations. The second phase of the MRAT project has already been kicked off and will bring more enhancements of the tool.

As more and more energy from renewable sources has to be transmitted, Europe’s transmission system operators (TSOs) often have a hard time ensure the overall system security and managing congestions. Sometimes it is necessary to take so-called Multilateral Remedial Actions (MRAs) with more than two TSOs involved. These complex MRAs are indispensable to resolve security violations, but they often entail high costs. A special scheme based on a rather complicated mathematical algorithm is used to distribute the share of costs following the single tie-line decomposition (STD) mechanism.

A 100 million Euros cooperation


Since its foundation in October 2011 the International Grid Control Cooperation (IGCC) for optimized control energy utilisation produced cost savings of more than 100 Million Euros. The organisation is comprised of the Belgian TSO, Elia SA and the TSC members 50Hertz, Amprion, APG, CEPS,, Swissgrid, TenneT, and TransnetBW.
