Notice of Stage 2 of the Regulated Electricity System Investment Plan

Date of notice:  19 April 2024

The Regulated Electricity System Investment Plan (RESIP), previously known as the Northern Territory Integrated System Plan (ISP), has completed the Stage 1, Delivery Methodology Development, and has procured the services of a leading consultant for delivery of Stage 2 and Stage 3 RESIP. The RESIP Delivery Methodology was approved by the Electricity Market Reform Implementation Task Force (EMRIT) as the mandated approach for delivering the RESIP as follows:

Stage 2 represents the finalisation of inputs, assumptions, and scenario report (IASR) as well as the forecast demand, techno-economic and technical system modelling of the RESIP. The NT RESIP Project Team has been in contact with relevant data owners and requested data, as identified in Stage 1,  which must now be provided to finalise the IASR during May 2024.

This notice advises and solicits any other interested party, that was not engaged during Stage 1 to present their data and/or candidate investments to be considered within the RESIP development.

The RESIP delivery contract was awarded late February 2024 to Amplitude Consulting and Go2 Power (RESIP Consultant). The RESIP Consultant is responsible for developing the summary input data in the form of an IASR, and development of the optimal development pathway that will represent the whole-of-system plan presented as part of the RESIP report.
