Ofgem launches call for input on draft LDES licence conditions
Ofgem has launched a call for input on draft special licence conditions for long-duration electricity storage (LDES) projects under the cap-and-floor scheme, seeking stakeholder views ahead of a statutory consultation expected in summer 2026. The proposed conditions would be implemented through modifications to the standard electricity generation licence and are intended to establish the operational framework for LDES projects awarded support under the regime. The draft addresses areas including revenue calculation methodologies, availability requirements, treatment of construction cost overruns, financial resilience provisions, and governance of the cap-and-floor financial models. Ofgem states that it is particularly seeking views on key policy areas such as the approach to setting floor levels, the treatment of market-related costs and optimiser fees, availability requirements for storage assets, and controls on structured transactions and revenue maximisation. Ofgem is also seeking evidence on developing policy issues, including obligations during system stress events, cybersecurity expectations, governance of algorithmic optimisation, and the potential consumer impacts of repetitive re-trading in electricity markets. The call for input closes on 20 April 2026.
