The Coordinator of Energy (Coordinator), in consultation with the Market Advisory Committee (MAC), is undertaking a review of Capability Class 2 Technologies.
At the 24 July 2025 MAC Meeting, in accordance with clause 2.3.17(a) of the Electricity System and Market Rules (ESM Rules) the MAC established the Capability Class 2 Technologies Review Working Group (CC2TRWG) to support the review.

- Whether the Demand Side Programme Obligation Duration remains consistent with the SEO; and
