On Wednesday 22 January, the GMM MFF established topic TS051/TS052 ‘Validatie & Conflicterende Biedingen’ (‘Validation & Conflicting Bids’). This topic is about validation of congestion services. Because congestion management is increasingly used, it is important that system operators use a uniform and conclusive method for validating congestion services. This makes it clear whether congestion services have been provided correctly. It is also necessary to prevent the activation of congestion services from being cancelled out by so-called conflicting bids for the same connection (e.g. in the context of balancing services).
The topic describes the intended solution by introducing a limit value on the connection. The system operator communicates this limit value to the connected party and the relevant market roles. When both redispatch, capacity-limiting contracts (CBCs) and other congestion services are activated, the connected party will have to comply with the limit value to demonstrate that the congestion services have been provided. If the limit value is exceeded, the system operator can settle the congestion-non-supply price with the connected party. In the topic document you can read how this should work in practice, for example with closed distribution systems. Now that the topic document has been adopted, the Scope Authority Congestion Management is starting to prepare the implementation in line with previously established topics. The topic document can be found on the website of Energiedatawijzer.
Principles for the application of aggregation in congestion services
On 22 January, the GMM MFF established high-level agreements for the application of aggregation in congestion services. These serve as the basis for the elaboration of a topic document. Based on previous topics, the agreements describe how aggregation can be made possible and how connected parties with a capacity of less than 1 MW can supply it. Think of practical agreements on how a ‘group’ of connected parties should organise forecasts, activation and validation of congestion services, among other things. What is involved in the exchange of messages between the system operators, the Congestion Service Provider (CSP) and other market roles involved? The working group has now started and expects to be able to share a more detailed topic document for peer review in the spring.
17 February: information session Congestion Management
Every month, Collective Congestion Management organises information sessions about the latest state of affairs. The next online information session (in Dutch) is scheduled for Monday 17 February from 14:00 to 15:00. Then we mainly focus on the intended implementation strategy for identified topics from Phases 1 and 2. Do you want to participate? Send a message to donald.kreiken@mffbas.nl.
