6 FAQs about [Prohibition of independent energy storage power stations]
Is energy storage regulated?
Whilst the Department of Business, Energy & Industrial Strategy (“BEIS”) and Ofgem have been supportive of energy storage and recognise the benefits and flexibility provided by the various technologies, there is no specific legislation on or regulation of storage at present.
Who regulates electricity storage?
Ofgem is the relevant regulator for electricity storage, though as noted above there is no specific storage regulatory regime. Ofgem has recognised that there are regulatory changes required to enable the full commercial development of storage and it has committed to working with other stakeholders to consult on such changes.
What is electricity storage?
Electricity storage is not separately defined in the GB legislative framework. For historical reasons, it is currently deemed to be generation for the purposes of licensing under the Electricity Act 1989. As a result, projects over 100MW (currently only the existing pumped-hydro developments fall into this category) must hold a generation licence.
What are the challenges for new standalone energy storage projects?
The challenges for new standalone energy storage projects are as follows: revenue uncertainty – the contract terms available for many of the available revenue streams are short in duration; at four years, the term of EFR contract is the longest. As a consequence, projects have to manage greater revenue uncertainty over the lifetime of the project.
Does Beis support electricity storage?
Electricity storage falls within the remit of BEIS. BEIS is supportive of the development of electricity storage with a consultation regarding the removal of barriers to its deployment expected shortly. Nevertheless, as stated above, a specific subsidy for storage is not currently expected.
Why are energy storage devices charged a higher operational cost?
higher operational costs – where an energy storage device imports electricity from the transmission or distribution system, it is charged as if the storage device is an “end-user” for the purposes of the Renewables Obligation, Contract for Difference, and Feed in Tariff charges.
