A key,but contentious test that guides major electricity network investments has been given an overhaul by the Australian Energy Regulator,in line with the rapidly changing face of the National Electricity Market and the wholesale shift to renewables.
改进，周五宣布，apply to the AER's regulatory investment test (RIT) guidelines – a cost benefit analysis network businesses must perform and consult on before making major investments in their networks.
作为David Leitch noted here,RIT-T——传输网络测试——已经，in particular been a"bone of contention"in the various reviews of the workings of the National Electricity Market,including the Australian Energy Market Operator's Integrated System Plan.
关于该规则的一个关键问题是它的主要功能正在失效，which – as the COAG Energy Council put it in its own review of the RIT-T last year – is to protect consumers from paying more than necessary for their supply of electricity.
Rather,many believe it has resulted in the gold-plating of networks – an overbuild of expensive infrastructure built to cater for a handful of peak demand events or unexpected one-offs,the costs of which are passed on to consumers via increasingly exorbitant energy bills.
The COAG review resulted in a number of recommendations on how networks could better do this job by changing the way they account for option value,政策发展和高影响，低概率事件，such as the now infamous system-black event in South Australia.
它还建议提供更新”the appropriate reflection of renewable energy and climate goals.""
AER周五表示，这些变化将使RIT-T变得更加强劲，efficient and timely,as well as more aligned wth the AEMO's integrated system plan"so network businesses take a more consistent and holistic approach to cost-benefit analysis.""
"The new RIT guidelines also support a system-wide approach to planning in the National Electricity Market.""
This seems to mean looking beyond the traditional more-poles-and-wires approach to bolstering demand hotspots on the network and managing the influx of large-scale renewable energy developments in certain areas,including microgrid,需求响应和储能解决方案。
"在AER要求修改国家电力规则之后，these transparent cost-benefit assessments now not only apply to network augmentations,but also to large replacement projects,"一份声明。
The AER said work on strengthening the role of the ISP in efficient network planning and investment was also being undertaken by the Australian Energy Market Commission and the Energy Security Board.
"These bodies will soon advise COAG EC on how to better coordinate generation and transmission investment and turn the ISP into action,"it said.
