The power of data in Gothenburg

27.09.2019

OSIsoft is a well-known manufacturer of application software for real-time data management, called PI System. On the second day of this year’s OSIsoft “PI World” user conference in mid-September in Gothenburg, Sweden’s second biggest city, the focus was on utilities and energy management in particular. One of the speakers on this day was Gábor Bús, Lead Data Visualisation & Analyses in our Service Operations business unit.

The topic of the Hungarian-born was “The Power of a Single Integrated Database”. He drew attention to the great responsibility of the 43 power transmission system operators (TSOs) in Europe. TSCNET Services enables them to bridge the huge differences in the characteristics and processing of their vast amounts of data. Several applications are hosted in different environments and work with different virtual identifiers that refer to the same physical network element, such as power lines or substations. Only the standardisation of the virtual identifiers and their storage in a single integrated data system makes it possible to use them effectively.

On the basis of predefined use cases, the experts at TSCNET have developed a total of 205 analysis templates, 13 notification templates, eight PI Vision displays and two ProcessBook displays to support and raise the efficiency of the operational activities. An early warning system for the Congestion Management service is also constantly being experimented with the help of machine learning and artificial intelligence. Gábor’s presentation and a recording of the speech are available freely.

Setting the course for the Hansa PowerBridge

23.01.2017

TSC member 50Hertz, one of the four German transmission system operators (TSOs), and the Swedish TSO Svenska kraftnät have signed a cooperation agreement on the binational DC interconnector Hansa PowerBridge on 19 January 2017 in Berlin, Germany. The contract between the two TSOs lays down substantial details regarding the planning and construction of the interconnector, such as the time schedule, the technical design or the cost allocation.

With a capacity of 700MW and a total length of 300km, Hansa PowerBridge will connect the electrical substation in Güstrow in the northeast German federal state of Mecklenburg-Western Pomerania with its counterpart in Hurva in the southernmost Swedish province of Scania. Naturally, the largest section of the interconnector will be realised as a submarine cable through the Baltic Sea. The estimated overall investment volume of the project amounts to more than €600m. Currently, 50Hertz and Svenska kraftnät are both preparing the respective official approval procedures. The call for tenders is expected for 2022 and the commissioning of the Hansa PowerBridge for 2025/26.

The energy production in the northeast of Germany is characterised by its high share of wind and solar power, while hydropower plays a major role in Scandinavia, hence also providing large amounts of storage volume. The Hansa PowerBridge links these two significant energy regions and enables the TSOs to balance energy dropouts in their national transmission systems and to avoid the cost-intensive throttling of generation plants. Rainer Baake, State Secretary in the German Federal Ministry for Economic Affairs and Energy, comments on the signing of the agreement: “The power line improves the integration of renewable energies into the transmission grid and thus contributes to climate-friendly and cost-efficient electricity generation.” Boris Schucht, Chief Executive Officer at 50Hertz, complements that in combination with the inner-German SuedOstlink power line project, the Hansa Power Bridge has the potential to serve as “a well adjustable long-distance link from Scandinavia across the northeast of Germany to the south”.

Challenges and opportunities in the north

16.08.2016

The Nordic transmission system operators (TSOs), Svenska kraftnät, Statnett, Fingrid and TSC member Energinet.dk issued a report summarising their views on challenges and opportunities affecting the Nordic power system in the years ahead until 2025. “Climate policy, technical developments, and a common European framework for markets, operation and planning” are expected to be the main drivers of change. The four TSOs understand that the changing environment will come along with a higher demand for flexibility. A follow-up report is porjected to be published in the second quarter of 2017.

Nordic power talks

11.12.2015

The four Nordic transmission system operators (TSOs), Fingrid, Statnett, Svenska kraftn, and TSC member Energinet.dk, invited regulators, authorities, and key market players to the “Roundtable of Nordic Power Stakeholders” near Oslo, Norway, to develop common understanding of both the threats and opportunities, and to discuss the future of the power system in Denmark, Finland, Norway, and Sweden until 2030. The Danish TSO Energinet.dk offers several documents to inform about the conference, including the TSOs’ strategy presentation.
