The objective of this project is to enable an energy storage system (ESS) to participate and compete in the reserve market. This will benefit consumers by increasing competition in the sector and enhancing the grid's capacity to securely and reliably transmit electricity.

The first stage of the project will enable the owner of a grid-scale battery ESS to offer injectable instantaneous reserve and lay the groundwork for wider participation by distributed battery ESS and other storage technologies. This stage requires an associated amendment to the system operator's procurement plan.

To be effective, the Code amendment has been developed in association with an amendment to the system operator's procurement plan.
