Imagine being able to bank your excess solar energy in a shared battery...well that’s what we’re trialling with our PowerBank community battery project.
We’ve partnered with Synergy to install two community-scale batteries utilising Tesla technology:
It’s an Australian-first trial to integrate bulk solar battery storage into the existing grid that also provides customers with a retail storage option.
Across the two battery projects, up to 129 households will have access to between 6-8kWh of virtual storage in the PowerBank at the cost of $1 to $1.90 per day to store their excess solar energy. It will provide a cost-effective and shared solution to energy storage that benefits both customers and the grid. In the first year of the Meadow Springs trial, 95 per cent of customers saved money on their power bills.
We own and maintain the battery, meaning customers don’t have to outlay the costs of purchasing a behind-the-meter battery.
The project will also support the region’s power supply during times of peak demand – when electricity consumption is at its highest – which is a smarter, customer-focused approach to infrastructure investment in the area.
Mandurah is Western Australia’s undisputed leader in the uptake of solar panels and demonstrates the community’s desire to integrate cleaner, renewable energy alternatives into their lives.
The region has also grown considerably in recent years, which is putting extra strain on the existing electricity infrastructure.
So, this trial comes at the perfect time to not only defer expenditure on new electricity infrastructure, but also give our trial participants more choice in how they manage their solar energy.
We plan to roll out at least 10 more community batteries in 2020.
