Capacity Market Restart

On 15 November 2018 the judgment of the General Court of the Court of Justice of the European Union had the effect of annulling the European Commission’s State Aid approval for the GB Capacity Market scheme and introduced a Standstill Period.

On 24 October 2019, the European Commission confirmed that the GB Capacity Market scheme is compatible with EU State Aid rules. The Secretary of State has notified ESC of the Commission’s decision and confirmed the occurrence of the deferred capacity payment trigger event and T-1 capacity agreement trigger event. This means capacity payments can restart under the GB Capacity Market scheme.

In November 2019 suppliers will be invoiced for the Standstill Collection Period Supplier Charge and the first post-Standstill month (December) Credit Cover will also need to be posted.

EMR Settlement has updated on our behalf guidance documents in preparation for this trigger (G22, G11, G17), which are available on the EMRS website.
