The Australian energy regulator has released its draft determination on a rule for speeding up new renewable electricity projects' connections to the power grid.
The Australian Energy Market Commission (AEMC) has released this determination as the nation grapples with an ambitious timeline to replace most of its coal-fired generation by 2030.
The AEMC has made changes to the R1 process that governs the engineering information that must be provided to the Australian Energy Market Operator (Aemo) and network operators for review before connection occurs.
As many as 583 projects — mainly wind, solar and battery storage generators — were queued awaiting connection as of last December, AEMC said, the Clean Energy Council (CEC), the peak body for Australia's renewable power developers, submitting suggestions for changes to the regime.
The draft rule changes would allow generators to demand written justification from Aemo and network operators if asked to submit further
modelling requests on possible system security issues stemming from their assets, remove barriers to "reasonable and pragmatic" revisions to generator performance standards and notify generators of the commencement and conclusion of the R1 process.
The CEC submitted that generators are often held responsible for network changes outside their control which leads to excessive rework and remodelling for "marginal or inconsequential improvements".
Submissions on the draft determination and rule changes will be open until 18 April with a final determination scheduled for 6 June.
Australia's federal government has moved to address stalling investment in renewable power generation with a Capacity Investment Scheme (CIS), to raise capacity by 32GW by 2030.
Canberra will provide revenue underwriting for successful CIS tender projects, with an agreed revenue "floor" and "ceiling" broken down into 23GW of renewable capacity representing A$52bn ($34bn) in investment and 9GW of "clean dispatchable capacity" consisting of A$15bn in investment.
Coal generated about 55pc of power for the east coast's National Electricity Market in 2023, with 39pc supplied by renewables.
