Slide 1: Workshop: Reflections on the implications of offshore bidding zone for balancing
Workshop Reflections on the implications of offshore bidding zone for balancing Kristof De Vos 24th of June 2022
Slide 2: Energy island, Nautilus and Triton Link to evolve to a meshed offshore grid
The Energy island, Nautilus and Triton Link together will evolve to a meshed offshore grid based on hybrid interconnectors and multi-terminal HVDC Creation of an offshore energy transmission hub in the form of an artificial island • Grid connection for 3,15 to 3,5 GW of additional offshore wind farm
Slide 3: Offshore bidding zone solution to connect offshore wind parks with hybrid interconnectors
Offshore bidding zone solution has to be considered to connect offshore wind parks in the presence of hybrid interconnectors following European regulations Home Market Offshore Bidding Zone BE BE Energy Offshore island BE BE bidding Bidding bidding Bidding zone bidding zone zone zone zone • The Home
Slide 4: Objective of the workshop
Objective of the workshop • During the first task force, the benefits of the offshore bidding zone approach were presented, with a focus on the energy market Optimal market outcome (guaranteed optimal dispatch) CEP 70% compliant (less need for TSO interventions RDCT) Capacity allocation (no ad
Slide 5: Implications for balancing: how to balance a bidding zone with only generation assets
Implications for balancing : how to balance a bidding zone with only generation assets ? Offshore Bidding Zone • How to manage reserve activations ? General introduction in this workshop • How to manage the imbalance price ? Topic subject to BE • How to manage reserve one of the next Offshore dimens
Slide 6: Available sector reports (on balancing aspects of bidding zones)
Available sector reports (on balancing aspects of bidding zones) ACER supports the European Commission’s proposals on how to integrate offshore renewable energy into the internal energy market (namely with offshore bidding zones (OBZs) • According to ACER, current market rules governing real-time tr
Slide 7: Legal framework
Legal framework • According to Article 2(13) of the Commission Regulation (EU) 2017/2195 of 23 November 2017 establishing a guideline on electricity balancing ‘imbalance price area’ is the area for the calculation of an imbalance price. As Belgium is based on a self-dispatching model, an offshore bi
Slide 8: Separate imbalance price area via separate LFC areas (1)
Most obvious approach to obtain separate imbalance price area is to implement separate LFC areas (1) • The Synchronous Area has the obligation to fulfil the frequency quality target parameters by using the frequency containment process. • A LFC Block is in addition responsible for the dimensioning o

Slide 14: Advantages of a separate imbalance price area consistent with offshore bidding zone
Beyond the legal obligations, defining a separate imbalance price area consistently with offshore bidding zone has clear advantage in terms of market and system efficiency. • Article 6(6) of the said Regulation (EU) 2019/943 stipulates that each imbalance price area shall be equal to a bidding zone,
