The concepts and algorithms are finalized for all T-SENTINEL modules, while IT development is ongoing. It is envisaged to provide live demonstration of currently developed functionalities related to redispatching cost-sharing.

Within the T-COORDINATION platform, detailed business rules have been refined. The IT development has focused first on delivering core functionalities to be reused for implementation of coordination and information use cases. The first tests for the Coordinated Security Analysis, Coordinated Capacity Calculation and Renewable Energy Sources (RES) are ongoing.

The T-MARKET intraday module is in its design phase; HUPX, EPEX SPOT and SEEPEX partners are working hard in order to finalize the final draft of the document, so far everything is going smoothly and the results are expected very soon.
T-MARKET Capacity Reserve module has finished its specification design phase, IMP partner is currently developing the first version of the module, and the test should start by June. By May, the Guarantees of Origin (GO) market module will start its development phase.
Within T-RES CONTROL CENTRE, TRINITY is finalizing the modules related to the advanced monitoring and control of RES Plants and is well progressing on the development of the Dynamic Map that will show the most suitable locations to install new RES. In addition, it is starting the design of the modules that will optimize the participation of RES in the different South-Eastern Europe (SEE) electricity markets.


TRINITY partners participate in the BRIDGE initiative, a European Commission initiative that unites Horizon 2020 Smart Grid and Energy Storage Projects to create a structured view of cross-cutting issues which are encountered in the demonstration projects and may constitute an obstacle to innovation.
TRINITY participates in its different Working Groups (WG) and Task Force (TF) such as the Data Management WG, Business Models WG, Regulations WG, and Research & Innovation Priorities TF. ETRA, SCC, and RTEi are the partners involve in BRIDGE tasks.
BRIDGE fosters continuous knowledge sharing amongst projects thus allowing them to deliver conclusions and recommendations about the future exploitation of the project results, with a single voice, through four different Working Groups representing the main areas of interest: Data Management, Business Models, Regulations and Customer Engagement.
Within the Data Management WG; TRINITY has contributed in preparing the delivery: “European energy data exchange reference architecture” and the report “BRIDGE report on TSO-DSO coordination”. The -DSO Coordination attempts to map the interactions between the network
operators (TSOs & DSOs), either between the same type of operators or between TSO and DSO.
The focus lies on market design and data exchange between the aforementioned actors and the way that this is implemented.
Concerning the Regulations WG, TRINITY has provided info for enriching the data of the Demo cases repository by providing information about a potential demo case about “Transnational GoO issuing in SEE”. Also, it was one of the promoters of the new working activities about cross border cooperation and markets integration, and it participated in the “Common taxonomy for services, products and markets” task focused on the topic of TSO/DSO product design, coordination models and market design.
The Business Model WG has not been active during the last two years. However, for the next year the intention of BRIDGE members is to reactivate it. Then, the intention of TRINITY is to participate as much as possible in order to promote the T-RES CONTROL CENTRE and collect valuable feedback from other projects.
Finally, under the Research & Innovation Priorities TF TRINITY is contributing on how to realize about what technologies, markets, value chains etc. have been predominant during the last 7 years in order to prioritize R&I for the next Framework Program.

T-SENTINEL in line with ACER decisions

The growing intermittency of electricity generation caused by renewables, as well as configuration of bidding zones and higher volatility of cross-border trades almost until last moment, increase the needs for redispatching measures. The costs of redispatching and countertrading amount to more than a billion euros per year according to ACER market monitoring reports. An efficient and coordinated framework for redispatching is an important component of a secure electricity system and an integrated European electricity market.

In December 2020, ACER adopted decisions on Methodology for Cost Sharing of Redispatching and Countertrading in CORE and SEE capacity calculation regions (ACER Decision 30-2020 and ACER Decision 31-2020). The methodology is based on three calculation steps: power flow decomposition, transformation and mapping. Under the H2020 FutureFlow project (2016-2019), EKC as the WP1 leader, lead the research on the topic of redispatching and redispatching cost sharing, which produced the Power Flow Colouring (PFC) method.
In the case of overloading on a particular network element, this methodology gives a quantitative measure (MW) of the involvement of each bidding zone i.e. it gives partial flows – loop flows, internal flow, market flows and PST flows created by each bidding zone as a “causer“ of redispatching activation. Together with transformation and mapping encompasses the whole process of compensation of redispatching costs with exact shares per area in overloading. This method (PFC) was recently selected by ACER as a target mechanism for power flow decomposition in CORE and SEE CC regions (as defined in above mentioned ACER decisions).
Within TRINITY project, EKC is working on the development of T-SENTINEL TOOLSET software module that will integrate all three pillars of ACER methodology (power flow decomposition, transformation and mapping), which will be delivered to Regional Security Coordinator - SCC Belgrade. With T-SENTINEL operational, SCC will be able to enhance current business practices in terms of coordinated security assessment, as well as loop flow calculation, thus improving the overall security of power system operation and fair allocation of redispatching costs in the South East Europe.

Next steps

In the short term, the consortium is preparing the upcoming review meeting of June, in which the European Commission will evaluate the performance of the first 18 months of the project. Moreover, the consortium will continue the development of the different TRINITY technologies in order to deliver their first version in September 2021.
