WA households are testing a new app that allows people to monitor their power consumption and pay their bills.

The MyPower pricing plan is on trial in the towns of Broome and Port Hedland, but the State Government says the infrastructure and retail model will be rolled out on a wider basis soon.

“This is the future of power in WA, as it just means people will be able to consume power, and buy power, according to a plan much like their mobile phone, with much more control and choice,” Mr Wyatt said.

“Clearly this is the way for Western Australians to take more control and also have a better understanding of their power bills.”

The app allows Horizon Power customers to monitor electricity usage from a smart meter installed in their house.

Users are charged on a more flexible model of pricing, due to the higher quality of usage data, so they can be rewarded for using less electricity during peak times.

Horizon Power managing director Frank Tudor said earlier trials had shown users were motivated to switch off unnecessary appliances.

“We're giving people instantaneous feedback on a phone app, so they're actually seeing how their energy consumption is going and can take immediate action,” he said.

Some households saw their power bills drop by up to 20 per cent.

“It is a good result, and means the incentive is there for people to be disciplined and get the signal about what their consumption at peak time means, and actually take action and be rewarded through that process,” Mr Tudor said.

“So it is a virtuous cycle with short, medium and long-term benefits.”

Mr Wyatt said it would take time for the necessary infrastructure to be set up to expand the system across the state.

“You need the network and the infrastructure there before you can have the retailer implement it,” he said.
