The rules enable the regulator to set the maximum prices network business can charge for services they provide. Prices are set every five years.
AEMC MAKES THE RULES
AUSTRALIAN ENERGY REGULATOR (AER) APPLIES THE RULES RULES
Natural Monopoly Sector Component 46.5%
Competitive Sector Component 53.5%

Council of Australian Governments (COAG) implements policy reforms of
national significance that require cooperative action by federal,
state and territory governments
COAG Energy Council is made up of the nation’s
energy ministers. They provide national leadership on energy market development which
is so important for the health of the national economy

Energy storage projects – connected and in operation
As of January 2019, there are four large-scale energy storage facilities that have connected to the NEM:
• A 100 MW/129 MWh lithium-ion battery storage system at Neoen’s Hornsdale wind farm near Jamestown in South Australia. The Hornsdale Power Reserve utilises Tesla’s technology and commenced operation in December 2017.
• A 30 MW/8 MWh lithium-ion battery storage system at the Dalrymple substation on the Yorke Peninsula in South Australia. The project is owned by ElectraNet and will be operated by AGL, and commenced operation at the end of 2018.
• A 30 MW/30 MWh lithium-ion battery storage system at the junction of four major transmission lines at AusNet Services’s substation near Ballarat in Victoria. The Ballarat Energy Storage System is owned by AusNet Services and operated by Energy Australia. The battery is now registered and operating.
• A 25 MW/50 MWh lithium-ion battery co-located with the 60 MW Gannawarra solar farm near Kerang in northern Victoria. It will be jointly owned by Edify and Wirsol, and operated by Energy Australia. It is now complete and in the process of being fully commissioned.

AEMC priority areas of reform
15
1. Generator access and transmission pricing
Shift from large geographically concentrated to small geographically dispersed generation
2. System security Services previously provided for free not necessarily provided by new generation
3. Integrating distributed energy resources
Increased adoption of small-scale solar and energy storage technologies
4. Digitalisation of energy supply Increased adoption of digital technologies
5. Aligning financial incentives with the physical needs
More variable demand and supply creating volatility
2019 Competition review looks at the solar PV and storage products being offered to customers and how these are evolving.
Embedded networks review - law and rule changes to strengthen protections and improve access to competitive retail offers for embedded network customers.
Coordination of generation and transmission investment review will reform the access and charging regimes for new connecting generators
Stand-alone power systems review – designing a new approach to regulating stand-alone power systems and microgrids owned and operated by third parties.
Electricity networks economic regulatory frameworks review is looking at ways to unlock the value of distributed energy resources
Current regulatory projects related to storage
16
Demand response mechanism developing a mechanism that would allow demand to be offered into the wholesale electricity market in a transparent, scheduled manner.
17
We have a unique system in Australia where anyone, any company, government, advocacy group or individual
person, can propose a change to the rules.
Collaboration is the key to success as it will deliver workable and lasting change.
