- Horizon Power successfully tests vehicle-to-grid (V2G) technology
- Exmouth trial shows potential for V2G to power homes, reduce power bills
- Technology has the potential to manage two-way charging to stabilise electricity grid
Horizon Power has successfully completed a 12-month trial testing technology to facilitate two-way charging of electric vehicles (EVs).
The Exmouth trial demonstrated that Horizon Power's vehicle-to-grid (V2G) technology has the potential to manage the two-way flow of energy from EVs charging and discharging into the power network, while ensuring stability and reliability.
The technology enables EVs to act as mobile energy storage systems.
Horizon Power conducted a range of tests exploring the future possibility of using V2G energy flow to power homes, reduce power bills, and stabilise the electricity grid.
It will use the findings of the trial to inform the development of products that will allow customers to get more from their EVs than just getting them from A to B. This could include helping them to power their homes or even earn money by feeding energy back to the grid.
The trial was the first of its kind in Western Australia and was conducted using the regional energy provider's Distributed Energy Resource Management System (DERMS).
DERMS used data from Horizon Power's power systems, connected solar, the EVs and weather forecasts (predicting the availability of solar energy), to successfully balance power system stability with customer needs.
DERMS is already used to ease electricity grid capacity constraints, enabling more regional households to connect rooftop solar.
As part of the Cook Government's Electric Vehicle Action Plan, the trial has enhanced Horizon Power's understanding of how energy flow from EVs can be incorporated into its microgrids, especially in regional and remote towns.
As Horizon Power develops DERMS, EVs have the potential to draw power from the grid to charge but also feed power back into the network when needed - for example, when demands for energy are at their peak or when the flow of energy in the system needs to be stabilised.
Horizon Power partnered with the Gascoyne Development Commission, Shire of Exmouth, Exmouth Chamber of Commerce and Industry, and WA Country Health Service, providing them each with a V2G-compatible Nissan Leaf EV and V2G smart-charging equipment for the trial.

As stated by Energy and Decarbonisation Minister Amber-Jade Sanderson:
"The success of this regional trial in Exmouth is an important milestone in our clean energy transition and in testing the technology that could make two-way charging a possibility in Western Australia.
"The findings confirmed for Horizon Power that its technology can manage EV charging and discharging intelligently, helping it to keep the grid stable while paving the way for flexible, customer-led energy products.
"Electric vehicle batteries are powerful. As well as helping to stabilise the grid they have the capacity to power homes and reduce energy bills.
"The success of this trial sets a strong foundation for EVs to be integrated into our power systems."
