Mannum Solar and
Storage Project – 30MW 

135 Mannum Road, Mannum, SA

Tetris Energy successfully developed the first 5MWac/7MWdc stage of the Mannum Solar Farm in South Australia. This project has been operational since mid-2019. The solar farm is located adjacent to the Mannum 33/132kV substation which connects to the SA Power Network feeders that are servicing the main Mannum to Adelaide SA Water pumps and pipeline. Canadian Solar acquired the project at the commencement of construction.


Revenues for the first phase are supported by a Power Purchase Agreement (PPA) the Tetris Energy entered into with Flow Power and a separate LGC agreement. The Mid-Murray region is home to several intensive agricultural businesses, which include large-scale dairy, a piggery, and vegetable cool rooms. Flow Power has existing supply arrangements in place with some of these customers, including leading wine producer Pernod Ricard Winemakers, which last year announced it would enter into a PPA with Flow Power as part of its commitment to source 100% renewable energy. Flow Power will look to expand its competitive retail offering on the back of the Mannum Solar Farm PPA.


Matthew van der Linden, Managing Director of Flow Power, comments: “We’re pleased to be working alongside Tetris Energy and Canadian Solar to deliver more effective, low-cost and renewable energy solutions to businesses in the Mid-Murray region and beyond.”
