Alstom and Unicorn Systems have been selected to provide a flexible energy market management solution for TenneT, one of the top five Transmission System Operators and the first cross-border operator in Europe. The five-year contract replaces a legacy infrastructure that currently supports all of TenneTs electricity market operations. 

Since 2011, the European Union has been transitioning towards a single, unified electricity market. The goal is to empower European consumers to choose between different electricity suppliers, while enabling a wider range of companies to enter the energy market. To better align with new market dynamics, TenneT has elected to institute a new infrastructure, one that is modular and comprehensive enough to support a complex Market Management process. The solution facilitates energy trade while ensuring network stability and security. It sends information from energy companies to TenneT, who then ensures that energy demand and production is always in balance. 

Alstom and Unicorn Systems, combining their expertise in Market Management Systems (MMS) and large complex information technologies, successfully created an interoperable joint solution to manage the network. Highly flexible, the solution allows TenneT to efficiently adapt to the technical and regulatory transformations of the market, such as the integration of renewable energy. It is fully up to date and compliant with recent grid standards and ENTSO-E[1] processes, which enable coordination and grid development within the European Network.  

The modular infrastructure will support the entire market management operation from scheduling processes, to imbalance management, to settlement[2] all while maintaining optimal service and adaptability to future market conditions. As part of the tendering process, Alstom and Unicorn Systems demonstrated that their joint solution is well in line with our business needs, and their energy IT technologies and domain expertise well-suited in the realm of an active European electricity market,  said Peter Hoffmann, Senior Manager System Operations of TenneT. 

Alstom and Unicorn Systems will also provide data migration, training of TenneT employees and technical support by knowledgeable and experienced staff. Alstom is proud to work alongside Unicorn Systems, and be chosen by TenneT to deliver a best-in-class IT solution for the Netherlands electricity market. Our experts have experience in delivering energy market systems all across US, Europe and Asia Pacific, said Patrick Plas, Senior Vice President of Power Electronics & Automation, Alstom Grid. 

It is a tremendous accomplishment for Unicorn Systems to succeed in this competitive tender for the largest transmission system operator. At present, we are working on many projects which are critical for the integration of European energy markets, said Jan Konrád, International Services Director, Unicorn Systems.

[1] ENTSO-E:  European Network of Transmission System Operators for Electricity represents all electric Transmission System Operators (TSOs) in the EU and others connected to their networks, for all regions, and for all their technical and market issues. ENTSO-E ensures better collaboration between the TSOs in a number of key areas, such as the development of technical and market-based grid codes and the coordination of system operation and grid development.


[2] The imbalance management and settlement process settles discrepancies between: the amount of electricity that a company has contracted to generate or consume (adjusted for any accepted Bids and Offers in the Balancing Mechanism) and the amount of electricity which the company actually generated or consumed.

Due to the nature of electricity, generators may generate more or less energy than they have sold; customers of suppliers may consume more or less energy than their Supplier has purchased on their behalf and traders may buy more or less energy than they have sold. In such circumstances, these Parties are regarded as being in imbalance and the energy imbalances (i.e. the amounts of energy generated or consumed and not covered by contracts) have, in effect, been bought or sold.
