Does low voltage energy storage need to be declared [PDF]

6 FAQs about [Does low voltage energy storage need to be declared ]

Why are we legislating electricity storage?

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.

Can long duration electricity storage help decarbonise our energy system?

We're consulting on the policy framework to enable investment in long duration electricity storage. Long duration electricity storage can provide an important contribution to decarbonising our energy system. For example, it can store renewable power and discharge it during periods of low wind.

What is long duration electricity storage (LDEs)?

Long Duration Electricity Storage (LDES) technologies contribute to decarbonising and making our energy system more resilient by storing electricity and releasing it when needed. LDES can also help reduce costs for consumers through reducing their bills and by avoiding the need for expensive electricity grid upgrades.

What is electricity storage & how does it work?

This measure will facilitate the deployment of electricity storage. The Bill amends the Electricity Act 1989 to, in effect, clarify that electricity storage is a distinct subset of generation, and defines the storage as energy that was converted from electricity and is stored for the purpose of its future reconversion into electricity.

Can long duration electricity storage save energy?

Long Duration Electricity Storage would reduce costs to consumers through lowering their energy bills, by avoided electricity grid reinforcement and avoided peak generational plant build. LCP's modelling estimates savings for the energy system (and ultimately the energy consumer) of up to £24 billion by 2050.

Should electricity storage be formalised as a subset of generation?

Formalising electricity storage as a distinct subset of generation removes current ambiguities and provides long term clarity and certainty over its treatment within the existing frameworks (e.g. planning and licensing) and possible future frameworks.
