Our generation

We have been supporting renewable energy across Australia for over 20 years and we’re just beginning.

We deliver more electricity sourced from renewables to the grid than our customers consume.

By becoming a customer, you can support sustainable and affordable energy.

South Australian Winery

Many of our customers are actually our generators. Like this family in South Australia who power their winery by farming the sun – their solar system has a capacity of 29.7kW.

“We are a 4th generation South Australian family business, operating a vineyard for 55 years, supplying winegrapes to South Australian wineries Taylors, Yalumba and Oxford Landing. 


These wineries have a strong focus on environmental sustainability, which we share, so in 2009 to reflect to reflect these values, we installed a 30kW solar system at our vineyard, which not only helped improve our environmental sustainability, but also our economic sustainability. 


During our first year of producing our own power and returning the excess to the grid, I became increasingly frustrated with my existing local power retailer, as I seemed to know more about solar then they did, and after making me feel like they were doing me a favour by purchasing my excess renewable power, I then began my search for a power company with values more in line with my sustainable way of thinking. 


Then I came across Diamond Energy, a 100% renewable energy power company. One phone call confirmed my decision to change, my phone call was answered straight away by someone with not only an understanding, but a passion for solar and renewables. 

Their rates were better than my retailer at the time, and they offer monthly direct deposits to your bank account for any credits for exported power, so no more chasing power companies for exported power payments!


I have now been with Diamond Energy for over 4 years, and continue to be impressed by their service, and support for any other projects that I am considering, big or small. This 100% customer focus means I will never have to look elsewhere for my power requirements again, a view shared by many of my family and friends who have now also made the change to Diamond Energy as their retailer.” – David Zadow, Riverland Grower
