Installing a grid-scale BESS requires planning consent. Planning is a devolved matter, and decision-making rules differ across the UK In England and Wales, decisions on BESSs (regardless of their capacity) are made by local planning authorities. In Scotland and Northern Ireland, BESSs require consent from either ministers or. . Although safety incidents for BESSs are rare, a common concern about BESSs is the potential fire risk of lithium-ion batteries(PDF). Lithium-ion batteries can catch fire because of a process called “thermal runaway”. It can. . There are no laws that govern the safety of BESSs specifically. However, individual batteries may have to adhere to product safety regulations, and. . The Commons Business and Trade Select Committee has raised concerns that the UK has “insufficient domestic manufacturing capacity”. [pdf]
Three distinct yet interlinked dimensions can illustrate energy storage’s expanding role in the current and future electric grid—renewable energy integration, grid optimization, and electrification and decentralization support.
Why are we legislating? Electricity storage covers a range of technologies that store low carbon energy for when it is needed, for example in batteries on the wall of your home or business, or in facilities that pump water to higher reservoirs when electricity is abundant, and let it flow back down through a turbine when it is scarce.
Therefore, the government has said a decarbonised power system will need to be supported by technologies that can respond to fluctuations in supply and demand, including energy storage. The government expects demand for grid energy storage to rise to 10 gigawatt hours (GWh) by 2030 and 20 GWh by 2035.
(B) Technologies that should not be considered as electricity storage • Capacitors and supercapacitors when used as circuit impedance components • Transformers • Inductors • Thermal energy storage when the stored energy is used directly as heat and not re- converted to electricity before being used
Alongside government, we have clarified our view that in the energy system, storage provides services equivalent to generation. Therefore, our view is that electricity storage – for licensing purposes - should be treated as electricity generation. We have previously stated that our approach to regulating storage4should be:
A strategic reserve of electricity storage is a critical investment to secure the UK’s energy supply against future shocks, but the Government is still equivocating over whether it is necessary to invest in one. “Since 2023, the Government has had a Department for Energy Security and Net Zero.

The Kriegers Flak Combined Grid Solution, a of offshore wind farms into the power grids of two different countries will be the first of its kind. This has the advantage that up to the capacity of the connection the produced power can be transmitted to the country with the highest demand and price, improving the economy of the wind farms. Secondly, the connection between Denmark and Germany can act as an interconnector, so power can be transmitted fro. [pdf]
The Kriegers Flak - Combined Grid Solution is the world’s first hybrid interconnector/OWP system.
As part of the Combined Grid Solution project, Kriegers Flak is interconnected with the German wind farm Baltic II, which is located less than 30 kilometers southeast of Kriegers Flak. This allows for fossil-free energy to be shared between Denmark and Germany.
Kriegers Flak will take advantage of this and be connected both to the Danish grid as well as to the 288 MW ″EnBW Baltic 2″ which is connected via the 48 MW ″EnBW Baltic 1″ to the German grid.
The wind farm is serviced out of Vattenfall’s service facility at the Port of Klintholm on Møn, approximately 100 kilometres south of Copenhagen. With Kriegers Flak a milestone for a fossil-free energy has been accomplished. For the first time ever, an offshore power grid connects wind farms located in two different countries.
The extension of one of the two Kriegers Flak substation platforms at sea was required for the interconnector project CGS. The cables from all the wind turbines in the wind farm are connected in the transformer station at the transformer platforms. The voltage is transformed from 33 to 150 or 220 kilovolts (kV) for efficient further transport.
Kriegers Flak is located in the Baltic Sea, 15-40 kilometres off the Danish coast. "Flak" means reef, and this one is named after the Danish naval officer Christian Krieger, who in 1840 mapped the Baltic Sea. The offshore wind farm covers the annual energy consumption of approximately 600,000 households.
