Our history

ZEN Technologies (Power and Energy) Pty Ltd was established in 2004 to develop innovative and sustainable energy technologies.

From his suburban Adelaide home, ZEN Energy Systems founder Richard Turner first explored solar energy for his children’s cubby-house to power a light and television. He discovered there were all kinds of solar panels, inverters, components and other parts that had to be bought separately and pieced together like a puzzle.

With climate change becoming a reality, it seemed that an integrated and affordable solution would soon be needed. With considerable research, negotiating and identifying world-class componentry, ZEN Energy Systems was launched and created its first range of home solar systems. They were affordable, easy to install and integrated for optimum performance.

US-based energy storage software and integration company Greensmith Energy entered into cross-ownership with ZEN, with the partnership bringing internationally recognised energy storage knowledge and product solutions to the Australian market.

Greensmith and ZEN also later cemented their partnership with Greensmith nominated as ZEN’s delivery partner in its bid for the South Australian big battery project.

Through a major industry merger in October 2015, ZEN Energy Systems relaunches as ZEN Energy with renowned Australian economist and climate change expert Professor Ross Garnaut as Chairman.

The new ZEN Energy emerged with ambitious plans to scale up renewable energy generation, from residential and small businesses to a level that could provide energy to entire communities and industries.

“I felt the company could be part of the story of innovation in the energy sector.”
– Ross Garnaut on his decision to help launch ZEN Energy and become chairman.

In an early win for the company, in July 2016 the South Australian government awarded ZEN Energy contracts to install battery storage demonstration systems at three government-owned buildings in Adelaide.

In September 2017 – just one month after entering the Australian market – Sanjeev Gupta’s global GFG Alliance, through its energy division SIMEC Energy, acquired a majority shareholding of ZEN Energy and launched a new joint venture, SIMEC ZEN Energy.

SIMEC ZEN Energy was tasked with improving energy security and reducing the cost of power for GFG Alliance and other large energy users across Australia through renewable energy solutions in front of and behind the electricity meter. In significant early wins for the new business, SIMEC ZEN Energy became the electricity retailer for the Government of South Australia, and delivered an innovative 8-year retail electricity agreement for a group of large energy users through the South Australian Chamber of Mines and Energy (SACOME) Joint Purchasing Electricity Buyers’ Group.

Responding to a need for a clearer path and truly integrated energy solutions for Australian energy users, SIMEC ZEN Energy rebranded as SIMEC Energy Australia.

Together, SIMEC Energy Australia and ZEN Energy has begun delivering complete front-of-meter and behind-the-meter renewable energy solutions for homes, business, industry, and communities around Australia.

ZEN Energy’s integrated approach with SIMEC Energy Australia, both members of GFG Alliance, has strengthened our capacity to provide energy users across Australia with affordable, reliable and tailored renewable energy solutions.
