Our Story - Flow Power

Our story It all started with a single lightbulb moment.

Flow Power empowers Australian businesses to unlock value from the wholesale energy market.  From retailing electricity, to providing the latest technology and expert advice, we partner with businesses to reshape how they manage energy.

In February 2018, Flow Power welcomed a major investor in the business Canadian Pension Fund, OPTrust . Committed to investing heavily in Australian renewables, OPTrust identified Flow Power as an integral player in the Australian energy market. Drawn to its innovative thinking, IP and technology, OPTrust believes that Flow Power holds real promise for the future of Australian businesses and the electricity sector at large.

A story of ideas.

You could say the story of electricity in Australia is a story of clever thinking. It all began in Sydney, back in 1863, when a single electric arc light was assembled on Observatory Hill in celebration of the Prince of Wales’ wedding.

This was Australia’s first lightbulb moment.

Slowly, the light continued to spread, until Australia was completely electrified — clever. Creating a National Energy Market in Australia.

This is what we now call the ‘wholesale energy market’.

But today, the fixed rate model means that traditional retailers block market signals. People are kept in the dark about the effects of supply and demand on the market, and there’s no incentive to change behaviour — even when we need to.

In 2009 a local engineer built a way for businesses to buy wholesale power. It allowed them to buy in a way that suited them and saved them money.

Today, with more control and options, Australia is putting more emphasis than ever on businesses powering their own success.

And now, with Flow Power, you can even buy power for your business direct from the wholesale energy market.

You can choose to manage your own energy, or put an expert in charge.

Today, we’re 100 people across five states
