About ERM’s two rule change proposals in at the AEMC
Two earlier articles today prompt this follow-on piece, specifically focusing on what’s being requested by ERM Power in two separate rule change requests relating to the MT PASA process.
What is the RRO and why has the South Australian Energy Minister just triggered it?
Perhaps missed amongst all the bushfire-related action in the NEM, the SA Minister for Energy last week initiated the Retailer Reliability Obligation. Guest author Allan O’Neil tries to come to grips with what this means, and what happens next?
Where’s Loy Yang A unit 2?
The ongoing (second) outage at Loy Yang A unit 2 is a timely reminder of the need to progress the 2 rule change proposals submitted by ERM Power with respect to MT PASA data duration, and granularity.

Out of the blue, an LOR2
Considering the extraordinary weather, bushfires, and a couple of large Victorian generators still not back from long term repairs, last week was probably less eventful for the NEM than might have been expected, but it certainly wasn’t incident-free. A very…
Limondale Solar Farm starts up – only the first 29MW component of a bigger planned station?
