TSO proposals for balancing market integration

20.12.2018

To pave the way for a well-functioning energy union, there are eight European network codes: regulations that are intended to promote the integration and coordination of the various national European energy markets. One of these codes, the Commission regulation establishing a guideline for electricity balancing (EBGL), is intended – as the wording implies – to integrate the national European balancing markets.

Cross-border balancing is crucial for the transmission system operators (TSOs) to continuously ensure that the grid frequency is kept within a defined security range and that the required level and quality of power reserves are maintained. The European TSOs have now substantially advanced the guideline implementation by submitting six proposals for balancing market integration and the creation of platforms for the exchange of balancing energy products to the competent national regulatory authorities (NRAs).

With the assistance of the European Network of Transmission System Operators for Electricity (ENTSOE), these proposals have been developed in close cooperation between all TSOs and consulted with stakeholders. Laurent Schmitt, ENTSO-E Secretary General, is convinced that the realisation of the TSO proposals will create a level playing field for all market participants and thus lead to increased cross-border participation, supply security, competition and share of renewable energy. Consequently, Mr Schmitt identifies a “true ‘win-win-win situation‘, good for customer, the environment and the economy”.

Publications on HDVC reliability and the balancing market

13.12.2018

The European Network of Transmission System Operators for Electricity (ENTSO-E) has adopted positions on two systemically relevant topics for the European energy market: the electricity balancing market and the improvement of high-voltage direct current (HVDC) system reliability. Two respective papers have been released by ENTSO-E. The first, a balancing guideline, gives a simplified overview of the target model of the European balancing energy market and explains the most important concepts and processes associated with this market and the platforms for the exchange of balancing energy products. In addition to the focus on the interaction of the different balancing processes, the legal framework of the target model is also briefly outlined.

In its position paper on HDVC reliability, ENTSO-E recognises HDVC as an increasingly important method of transmitting large quantities of electrical energy for the Europe-wide transmission grid. As new HVDC connections play a key role in the future development of the continental transmission system, the reliability, availability, compatibility and robustness of the technology will be crucial for market and system security. For future challenges, high system security and the needs of an efficient European integrated market, it is essential that the owners of HVDC installations, together with other relevant HVDC stakeholders, focus not only on technology innovation but also on further process development, HVDC network integration studies and the maintainability to be carried out by transmission system operators (TSOs). ENTSO-E strongly supports more efficient cooperation between all HDVC players.

ENTSO-E has released a European electricity balancing guideline as well as a position paper on improving the reliability of HVDC systems  (picture of HVDC Plus IGBT converter modules: Siemens AG, www.siemens.com/presse)

Austrian research on battery based balancing

17.05.2018

The energy transition makes every market participant consider how to adapt to the rapidly changing conditions within the energy sector. Among other things, this means for the electric transmission system operators (TSOs) to respond to the weather dependence and thus volatility of the wind and solar energy generation. Dr. Ulrike Baumgartner-Gabitzer, CEO of the Austrian TSCNET shareholder APG, specifies the relating strategy of the TSO: “As APG we try to meet these challenges with the search for technological innovations.”

The modernisation and extension of the grid is undoubtedly of great importance, but TSOs need to think beyond that. Electricity grids increasingly require highly dynamic system elements that can compensate for short-term frequency deviations. In this context, storage technologies to stabilise the power grid are worthy of profound consideration. For this reason, together with the Austrian Institute of Technology, the Vienna Technical University and three subsidaries of Verbund, Austria‘s largest electricity provider, APG has launched a technology-neutral research project on battery-based balancing solutions: “Advanced Balancing Services for Transmission System Operators”, short ABS4TSOS.

The name similarity to the vehicle assistance system ABS (Anti-lock braking system) is by no means a coincidence. ABS4TSOS aims at automatic support systems and new mechanisms for the operation of the grid, which contribute to the maintenance of frequency stability and are therefore somewhat analogous to ABS. This includes all possible applications of a battery storage system in order to increase supply security. “ABS4TSO will address the question, in which way storage technologies can contribute to stabilising the grid in the future,” comments Dr. Baumgartner-Gabitzer.

In June 2019, the operation of the specifically designed battery storage system will commence at APG‘s substation Wien Südost. Subsequently, system functions and possibilities will be thoroughly examined. The project runs until the end of April 2021 and is endowed with €2.6m, which are borne by the project partners and the Austrian Climate and Energy Fund.

ELES coordinates FutureFlow

10.02.2016

The international four-year FutureFlow research project kicked off about a week ago will be coordinated by TSC member ELES, the Slovenian transmission system operator (TSO). The €13m project funded by the European Commission’s Horizon 2020 programme is designed to explore new solutions for balancing the electricity system and for managing the flows in the European electricity grid.

Efficiency by balance

30.10.2015

Balance between supply and demand constantly has to be ensured by transmission system operators (TSOs). TSC member Swissgrid, Switzerland’s TSO, analysed historical data of its balance group system including balance energy price mechanism and published an detailed article about the results in the trade magazine “Energy Policy” today. One of the key learning: “Little effort is necessary to make a good profit at the expense of system security”.

New transparency platform

05.01.2015

In accordance with Regulation (EU) No 543/2013 on the submission and publication of data in electricity markets, the new ENTSO-E Transparency Platform started today. The microsite gives fundamental information related to generation, load, transmission, and electricity balancing submitted by the transmission system operators (TSOs).
