The Gas and Electricity Markets Authority (GEMA) v R (SSE Generation Limited & Ors) (SSE)

The Gas and Electricity Markets Authority (GEMA) v R (SSE Generation Limited & Ors) (SSE)

GEMA acted lawfully in adopting a non-compliant interim methodology as a stop-gap measure, given the procedural constraints and the need to avoid a worse outcome, provided the ultimate objective was full compliance. The definition of 'congestion management' in the 2019 Recast Regulation is not limited to interconnectors/international trade but applies to congestion across the entire transmission system; however, the EU retained law definition in force in Great Britain is narrower due to a legislative drafting error, which the court declined to correct judicially.

Procedural Posture

Judicial Review / Statutory Appeal / Court of Appeal Judgment on Appeal

  1. 1 Whether GEMA acted lawfully in adopting a non-compliant interim methodology for transmission charges as a stop-gap measure pending full compliance with the law.
  2. 2 Whether the definition of 'congestion management' for the purposes of transmission charging is limited to interconnectors/international trade or applies to the entire transmission system.

Ratio Decidendi

GEMA acted lawfully in adopting a non-compliant interim methodology as a stop-gap measure, given the procedural constraints and the need to avoid a worse outcome, provided the ultimate objective was full compliance. The definition of 'congestion management' in the 2019 Recast Regulation is not limited to interconnectors/international trade but applies to congestion across the entire transmission system; however, the EU retained law definition in force in Great Britain is narrower due to a legislative drafting error, which the court declined to correct judicially.

Court Disposition

Appeal by GEMA allowed; cross-appeal by SSE allowed.

Orders

  • The appeal by GEMA on the lawfulness of the interim methodology is allowed; GEMA's staged approach was lawful.
  • The cross-appeal by SSE on the definition of 'congestion management' is allowed; the correct definition is not limited to interconnectors under the 2019 Recast Regulation.
