Homes will be equipped with rooftop solar panels, EV-managed charging technology, smart air conditioners and smartphones, all connected by smart software – a virtual power plant in the making

The push towards electrification is accelerating and will require smarter energy management to match demand with supply and provide the types of services that will support a renewable grid. Markets and business models are changing to meet this need, as are households. The most important principle in the new energy-buildings-transport-technology nexus is that a […]

Your home’s power plant – turning solar energy, battery, electrical appliances and electric vehicles on the roof into a source of energy used by the energy market

IEEFA Australia: Virtual Power Plants are the Future of Electricity Retailing

March 21, 2022 (IEEFA): As Australia passes three million rooftop solar installations, households looking to buy a battery storage system or an electric vehicle can be part of a new type of plant electricity resulting in faster and cheaper decarbonization. In the future, so-called “virtual power plants” that harvest distributed renewable electricity and demand response will play […]

We need a mission-oriented energy policy

IEEFA Australia: What the energy market could learn from an economics professor and a moon landing

Energy market organizations reluctantly recognize that governments interfere and always will. It would be more tolerable if everyone was on the same page. To date in Australia, there has been no shared vision. The absence of a coherent national energy policy caused a rollercoaster of investments and meant that we did not have the […]

The resources behind the meter – rooftop solar, electric vehicles, batteries and smart devices – need to be optimized or households will pay more in the energy transition

In July 2020, the Energy Security Board (ESB) released a consultation paper proposing that technical standards for distributed energy resources (DERs) – rooftop solar, electric vehicles, smart appliances and everything in between – be governed by a new way. Unlike the existing mess of multiple forms of uncoordinated norm setting, a […]

The sun will power much of our future – policy and regulation for Australia’s electrification must embrace distributed energy resources

IEEFA Update: A National Electric Vehicle Policy and Further Steps Towards Australia's Electrification

Amid global coal and gas price volatility, Australia’s electrification via rooftop solar is the clear winner in the race for the cheapest energy. Critics who claimed economies of scale were lacking when Australia began subsidizing household rooftop solar, maintaining the focus on large-scale solar, overlooked the economics of production and colocation load. Put […]

Make the right technical decisions about DER

IEEFA Australia: Ahead of solar, woefully behind in distributed energy resource standards

Despite being ahead of rooftop solar installations, Australia lags behind other jurisdictions (such as Germany and California) in establishing reasonable governance arrangements for technical standards distributed energy resources (DER). DER technical standards – covering smart appliances including rooftop solar systems, air conditioners, electric vehicle (EV) chargers, swimming pool pumps and others – are designed […]

It’s time to think big about DER on a small scale

IEEFA Australia: ESB Fails to Make Substantial Progress on Integrating Distributed Energy Resources

The Energy Security Board’s (ESB) final advice on post-2025 market design to energy ministers has been highly controversial. Firstly, there was the unnecessary proposal of a capacity payment paid by electricity consumers to power stations not only for the electricity they produce, but also for the size of the capacity installed in the station, regardless of either the way […]

A useless “solution” to a problem that has already been solved

IEEFA Australia: Solar export tax is two steps forward, one leap back for electricity consumers

A landmark decision announced yesterday requires electricity distribution networks (local pole and cable companies) to support energy exports from household rooftop solar systems, batteries, electric vehicles (EVs) and other consumer energy devices. The IEEFA notes that the new Australian Energy Market Commission (AEMC) rules are two steps forward, one leap back for electricity consumers. AEMC did […]

Energy ministers must rethink how to mandate demand response for household appliances

IEEFA Australia: Five issues with the AS4755 demand response standard

As Australia’s electricity system transitions to variable renewable sources, the need for smart solutions such as demand response increases. Household Demand Response provides options to increase or decrease an appliance’s power consumption. It can also be used to alter the flow of any on-site power generation, for example using excess solar generation to charge […]

Energy ministers urged to rethink AS4755 against more beneficial and consumer-friendly international solutions

IEEFA: Applying an outdated Australian-only demand response standard is not in the long-term interest of consumers

August 5, 2021 (IEEFA Australia): Imposing a new Australian standard for swimming pool pumps, air conditioners, electric storage water heaters and electric vehicle chargers will lead households to outdated technology, according to a new Institute for Energy Economics and Financial Analysis (IEEFA) report. Australian energy ministers have decided that various home appliances sold in the […]
