Irish smart-grid technology company Viotas has sold its Australian arm to energy-tech firm PowerSync.

Founded in Limerick in 2013, the Viotas model is based on energy grid flexibility. Viotas helps large electricity users earn revenue by being flexible in how they use, generate, and store power. Viotas develops metering and control hardware and software.

The company launched in Australia in 2020 as its first international market, and has now announced a deal for Australian firm Power Sync to acquire those operations. It has also signed a memorandum of understanding with PowerSync, which will see PowerSync offer Viotas technology and innovation to Australian customers.

“Six years ago we took technology built in Ireland to Australia and started from scratch. The team built one of the largest grid flexibility portfolios in Australia, that will now serve to springboard PowerSync’s ambitious growth in the market," said Viotas chief executive Paddy Finn.

"While we continue to broaden what we offer in Ireland and the USA, and building both into hubs for adjacent markets, our memorandum of understanding with PowerSync extends the reach of Viotas Grid Intelligence technology by making it a competitive advantage for other ambitious operators.” Viotas built its Australian business from a standing start into an industrial demand-response powerhouse with 227 MW of flexible energy demand.

The Limerick-headquartered firm will now place increased focus on growing in Ireland and the USA. In Ireland, where it was founded, its priorities include broadening grid flexibility services for large energy users; in the USA, its priorities include helping industrial businesses and data centres earn revenue from grid flexibility.
