New Energy Technology and the Future of Energy Complaints in Victoria

Charging Ahead investigates the current and likely future growth of new residential energy technology in Victoria, in an effort to anticipate the consumer issues that small energy users will face as we transition towards an increasingly decentralised, decarbonised energy system.

This is an important investigation for EWOV, and is part of our ongoing commitment to ensuring we remain accessible to the energy users of Victoria.

Executive Summary

Click here for an overview on this report's findings.

Residential Solar PV

EWOV currently covers energy retailers and distributors - not solar installers. Learn more here.

Residential  Batteries

Currently these don't have high market penetration in Victoria, but this is expected to change as battery prices reduce. More here.


Microgrids are still in their very early development stage, but hold significant future potential for remote and/or fringe communities. More here

Electric vehicles

Vehicles spend 95% of their life-time parked, so collectively, EVs are likely to provide a huge energy storage resource. Further reflections here.

The future of DER storage

We consider Virtual Power Plants (VPPS) and Peer to Peer (P2P) trading here.

Home Energy Management Systems (HEMS)

This new technology platform allows energy consumers to monitor and manage their home energy use. We reflect on this here.

Policy Spotlight: Monash Microgrid

Monash University has committed to zero carbon emissions by 2030. Read about two projects that have emerged from this here.

Policy Spotlight: Bruny Island Battery Trial

There have been 34 PV-battery systems installed as part of the Bruny Island project. Learn more here.

Additional Resources: Hypothetical Case Studies

Buying into a new property with pre-installed solar panels, Claire found that she wasn’t receiving the solar feed-in tariff she expected, because her distributor had imposed export limitations on her section of the grid.

For their retirement, elderly couple Rick and Gary moved into a lifestyle village that runs off a microgrid. Not understanding what that meant at the time, they now demand to be disconnected from the microgrid so they can access the retail energy market through the primary grid. 

Amal and Kai use the storage capacity of their electric vehicle (EV) to participate in a Virtual Power Plant (VPP). They’re frustrated that the VPP sometimes leaves their car battery drained, limiting their mobility.

Eleni and Dennis have moved into a rental home, and their in-built Home Energy Management System (HEMS) is causing tension

Padmini and Vinoth have signed up for Peer-to-Peer energy trading (P2P), but the trading software constantly malfunctions and they believe they’re missing out on significant potential benefits.
