Yesterday AEMO published the 2025 edition of its Enhanced Locational Information (ELI) report, which aims to provide more information about locational characteristics of the power system for the purposes of investment, regulation and planning decision making.
The report is a newer addition to the AEMO’s suite of annual reports, with the 2025 ELI being only the second edition, following last year’s inaugural release. The press release for this year’s report stated:
The ELI report, a key deliverable of the Energy Security Board reforms, is produced using a broad range of AEMO’s planning, forecasting and operational reports, as well as broader industry published information from transmission network owners and governments.
AEMO’s Executive General Manager of System Design, Merryn York, said building a reliable and efficient electricity system depends on investing in the right places.
“Opportunities exist in all NEM regions for renewable and firming projects to deliver energy, capacity, and network support services,” Ms York said.
“This report presents key locational data to help investors understand where their projects are most likely to succeed, and where challenges, such as network congestion, curtailment, or energy losses, may arise.
“Not all locations are equal, and geographic network conditions must be a critical part of investment decisions,” she said.
As time permits, we’ll surely dig into the report here at the Global-Roam office — but Figure 2 on Page 5 (shown below) was one of the more interesting data visualisations that grabbed my attention from a a quick initial skim this morning.
AEMO is hosting a webinar and Q&A session for the ELI report on Wednesday the 23rd of July at 10am AEST.
