Heavy goods transport in Franconia


Over the upcoming weekend, an 360t generator will be hauled to TenneT’s new €100m transformer station in Bergrheinfeld in northern Bavaria, Germany. The generator is the centrepiece of a rotating phase shifter designed to foster the integration of renewable energies. TSC member TenneT Germany is one of the four German transmission system operators (TSOs).

Substation re-opened following refurbishment


During the last two years, the substation in Karben, 20km out of Frankfurt/Main, Germany, underwent a €20m refurbishment and extension. Now it was re-opened by Tarek Al-Wazir, the Hessian Minister of Economics, Energy, Transport and Regional Development, and Urban Keussen, the chairman of the management board of the German transmission system operator (TSO) TenneT TSO GmbH.

Italy on a daily basis


The D-2 NTC capacity calculation project for the transmission grid at the northern Italian borders has reached a major milestone with the start of the so-called external dry run phase: The values of the daily capacity calculation performed by experts of TSCNET Services and Coreso now get published on the website of the Capacity Allocation Service Company (CASC). The calculations are based on the inputs of the five transmission system operators (TSOs) involved (RTE, Terna, and the TSC members APG, Eles and Swissgrid). Congratulations to all involved!

DolWin1 grid connection handed over


Two thirds of Germany’s federal government’s expansion target achieved: TSC member TenneT, the Dutch-German transmission system operator (TSO), has brought DolWin1 into operation. The high voltage direct current (HVDC) transmission facility has a capacity of 800MW. The power line runs 75km as a subsea cable from the DolWin alpha converter station to the landfall point and another 90km as an underground cable to the converter station in Lower Saxony, Germany.

First Network Code adopted


The European Union (EU) published its guideline on Capacity Allocation and Congestion Management (CACM) in the Official Journal. The CACM guideline is the first of the ten network codes to have completed the full legal process. It is expected to contribute to the continued decarbonisation of Europe’s economy.

Peder Andreasen, President of the European Network of Transmission System Operators for Electricity (ENTSO-E), emphasised the crucial role European transmission system operators (TSOs) have “played in pulling this law through”. In a press release issued today, TSC member APG, the Austrian TSO, welcomes the CACM guideline as a “vital component on our way to an integrated European energy market”.

Operating at full capacity


A conceptual task force (CTF) consisting of dedicated experts at TSC has developed a coordinated intraday capacity calculation (IDCC) concept. It proposes an advanced hybrid-coupling model and takes account of the requirements set by the capacity allocation and congestion management (CACM) guideline for the implementation of a single energy market across Europe. Although the concept is based on flow-based (FB) capacity calculation, it allows the use of available transfer capacities (ATCs) as well.

The concept describes two high-level business processes for IDCC, one based on a day-ahead common grid model (CGM), and the other based on intraday CGMs. A key element in the IDCC concept is the availability of information close or at least closer to real-time. In this context, the task force developed a new GSK methodology (generation shift key/s). The conceptual work is to be followed by a proof-of-principle stage. The concept serves as a starting point for a coordinated IDCC concept supported by the European transmissions system operators (TSOs).

New EU Energy Diplomacy initiative


Yesterday, the European Commission issued a press release about an EU Energy Diplomacy Action Plan developed on ccoperation with the European External Action Service (EEAS) and EU Member States. The European Commissioner for climate action and energy said that the EU would zero in on “diversification of sources, supplies and routes, energy security and safety, climate protection and the global promotion of clean energy”.

IRENA report on renewable energy capacity


The “Renewable Energy Capacity Statistics 2015” contains a lot of details on renewable energy capacity and use worldwide. 2014 was a record year for the renewable power sector with 133GW of net additions. China accounts for 26% of the global total of hydropower capacity and even 31% of the global total of wind capacity installed at the end of 2014. With 38.2GW Germany is the country with the highest installed solar capacity (21% of the global total of 179.6 GW). The report is released by the International Renewable Energy Agency (IRENA), an intergovernmental organisation to promote adoption and sustainable use of renewable energy.
