Update of the Voltage Service Provider Terms & Conditions for the 2027-2028 contractual period

Context

The recent and future evolutions of the Belgian power system have led Elia to publish in October 2018 a Study on the future design of the ancillary service of voltage and reactive power control to address the required changes of the Voltage and Reactive Power Control Service due to :

• the introduction of Network Codes in the Federal Grid Code, 
• the shift in the energy landscape in Belgium from large centralized to small decentralized generation
• the required rewording of the Terms and Conditions to make them technology neutral, and
• the requirement to let parties other than the Access Responsible Party to deliver the Voltage and Reactive Power Control Service

In December 2023, Elia published another document Voltage service and reactive power control review and recommendations for design optimizations as part of the Public Consultation of February and March 2024. This document included a description of the proposed changes to the MVAr service. This Public Consultation focuses on the Terms & Conditions updated with the proposed MVAr service changes.

Period

Elia invites all stakeholders to submit any comments and suggestions they may have on the document submitted for consultation.
