About us



We're Upstream


Upstream Energy has been delivering innovative clean energy solutions to the domestic Australian energy market since 2013.

Founded and based in Sydney, Upstream was one of the first providers of solar PPAs in Australia - and has rapidly expanded by delivering real customer value.


Upstream operates over 300 private power stations for organisations across Australia. We generate energy for Large Format Retail clients as well as schools and small businesses. These renewable systems are located not just in metropolitan areas like Darwin, Perth, Adelaide, Brisbane and Launceston - but also remote and regional towns including Broken Hill and Mount Isa.


With a focus on offering businesses an accessible and practical path to energy ownership, Upstream is making energy independence a reality for organisations of scales large and small, in an environment of ever increasing grid energy prices.


Here's our capability statement.
