This conference will examine next steps for UK energy storage policy, regulation, and market development.


We expect discussion to focus on priorities for long-duration energy storage (LDES) in supporting the UK’s decarbonisation targets, the Clean Power 2030 Action Plan, and the new cap and floor scheme, as well as wider issues for investment and regulatory frameworks to enable large-scale deployment.


It will bring key stakeholders and policymakers together to discuss implementation of the LDES cap and floor scheme, following publication of the Technical Decision Document. Delegates will assess prospects for the scheme in stimulating private investment, alongside alignment with broader grid and market reforms, and considerations for technology eligibility, capacity targets, and deployment timelines.


Sessions will consider the interaction between LDES and the wider electricity market, the role of National Grid and NESO, and potential measures to accelerate grid connections and infrastructure development. Wider policy such as planning reform will also be examined, including measures in the Planning and Infrastructure Bill and implications of updates to the Nationally Significant Infrastructure Projects regime.  


Further sessions will examine how a balanced approach to energy storage deployment can be achieved, including the roles of varying technologies such as pumped hydro, liquid air energy storage, and flow batteries, as well as emerging innovation and priorities for R&D going forward.


Attendees will also consider Industrial Strategy, skills and supply chain development, and investment support, including the role of Great British Energy and the National Wealth Fund. Further discussion is expected on implications for Scotland, where major LDES projects are underway, and the UK’s position in global energy storage leadership, including its commitments under the COP29 Global Energy Storage and Grids Pledge.


With the agenda currently in the drafting stage, overall areas for discussion include:


  • LDES cap and floor scheme:
    • evaluating the framework’s design - strategic, policy, and regulatory considerations - fostering investor confidence, while managing consumer costs
    • assessing implications of eligibility criteria, application processes, and deployment timelines - achieving a balance in incentives for innovation and established technologies
  • Infrastructure and Planning Bill:
    • implications of proposed planning reforms for progress of energy storage deployment and grid integration - environmental protection priorities, alongside energy security needs
    • changes to land acquisition and local authority powers - new environmental compensation measures and storage site approvals
  • Clean Power 2030:
    • integration of storage within decarbonisation pathways - the mix of short-duration and long-duration - offshore wind and nuclear expansion - achieving flexibility targets
  • regulatory coordination and market design:
    • considerations for electricity market design changes to support storage deployment - options for capacity market reforms to accommodate storage
    • alignment of Ofgem, NESO, and DESNZ responsibilities - assessing potential requirements for a strategic energy reserve
  • grid connectivity:
    • addressing delays in securing connections - streamlining planning approvals and other options for accelerating deployment - local authority capacity constraints
    • coordination of grid infrastructure upgrades with storage expansion - assessing the impact of proposed updates to the NSIP regime on storage project approvals
  • investment and funding:
    • strategic considerations for growing private and public funding, and the mix of sources - addressing barriers to securing capital for emerging technologies
    • the role of the National Wealth Fund in supporting long-term storage - priorities for Great British Energy
  • innovation:
    • assessing the future mix of established technology, including pumped hydro and emerging alternatives such as liquid air and flow batteries
    • priorities for R&D towards improved efficiency and cost-effectiveness - options for supporting commercialisation of new technologies
  • UK-wide development:
    • learning from investment and initiatives in Scotland - devolved planning frameworks - regional investment strategies and priorities for England and Wales
  • public engagement:
    • addressing local concerns regarding safety, noise, and added pressure on local infrastructure pressure - transparency in consultation and equitable sharing of benefits
  • skills, workforce, and industrial strategy:
    • priorities for the Office for Clean Energy Jobs - support for UK-based supply chains and regional economic development
    • integration of storage priorities within broader industrial strategy frameworks
  • international leadership and trade:
    • strategic approaches to positioning the UK as a global leader in energy storage innovation - addressing supply chain risks, including ethical sourcing of critical minerals
    • alignment of domestic policy with the COP29 Global Energy Storage and Grids Pledge - opportunities for investment and technology exports
