Part 7: Market Reform and Consumer Protection Section 213: Electricity storage
Section 213 amends the Electricity Act 1989 to 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.
	A non-exhaustive list of technologies that are considered electricity storage includes electro-chemical batteries; gravity energy storage systems; air-based storage systems; kinetic energy storage systems; thermal storage where the stored chemical energy is then converted back into electricity.
	The definition does not include the following:
Systems which convert electricity to another energy vector and back to electricity, where the other energy vector is not stored within a closed system. For example, power to gas to power systems which do not reconvert into electricity the same energy as was converted from it. This is because it is not the same energy being reconverted to electricity.
Systems which store energy that has been converted from electricity, but that energy is not then reconverted back to electricity. For example, thermal systems where the stored energy is used directly as heat. This technology lacks the key final stage of reconversion to electricity, meaning that it does not act as a temporary store with respect to the electricity system.
Industrial processes powered by electricity whereby the reconversion of potential energy into electricity is a by-product of another process. This is because such processes are not used to perform storage on the electricity system as the term is properly understood.
Network equipment whose primary function is not energy storage on the power electricity system. For example, capacitors and supercapacitors (where used as circuit impedance components), transformers and inductors are licensable as equipment or apparatus that are used for, or for purposes connected with, the transmission or distribution of electricity, rather than its generation. This is because they are not used to perform storage on the electricity system as the term is properly understood.
