What does regulatory evolution in Great Britain mean for long duration energy storage?
As Great Britain’s electricity system becomes more complex, the question is no longer whether long-duration energy storage is needed — it's how its value should be assessed. As renewable generation expands and electricity demand grows through electrification, artificial intelligence (AI) and industrial decarbonization, resilience is becoming just as important as capacity.
This publication explores an emerging shift in electricity system planning, from relying primarily on market outcomes to designing resilience into the future grid. Regulators, developers and network operators are evaluating how portfolios of complementary assets can strengthen overall system performance.
Using recent developments in Great Britain as a case study, Dr. Maureen Paul examines what this shift means for the future of long-duration energy storage and technologies such as Compressed Air Energy Storage (CAES), and why the next phase of the energy transition will depend on how flexible assets are selected, positioned and valued — not simply how many are built.
This publication explores:
- Why resilience is becoming a defining measure of future electricity systems.
- How portfolio diversity and locational planning create greater system value than technology selection alone.
- What emerging regulatory approaches mean for the future deployment of long-duration energy storage, including CAES.
