This note is not part of the amendment, but is intended to indicate its general effect.

This amendment to the Electricity Industry Participation Code 2010 ("Code") comes into force on 3 May 2022.

The amendment amends Part 1 and Part 13 of the Code to enable new types of instantaneous reserve, such as battery energy storage systems, to be offered as an ancillary service in the wholesale market. The amendments to Part 1 of the Code include the introduction of a new defined term, "energy storage system", which refers to equipment that is able to take electricity from a network, store the energy in another form and provide injection. The definition of "instantaneous reserve" is also amended to generalise its meaning and restructure the definition into two categories, "interruptible load" and "generation reserve". A new defined term, "generation reserve'' is introduced to refer to all forms of injectable reserve, including energy storage systems. Other consequential amendments to definitions are also made. Part 13 and clause 8 of Schedule 13.3 are amended to reflect the changes to definitions in Part 1 of the Code. These amendments are intended to allow battery energy storage systems and future storage technologies to offer instantaneous reserve, both when charging from and injecting energy into, the electricity grid.

ln addition to this amendment, the procurement plan has been amended to update the corresponding technical performance requirements for instantaneous reserve.
