Merredin Solar Farm

Western Australia’s Largest Operating Solar Farm.


Risen Energy developed and currently operates the 132MW Merredin Solar Farm in Merredin, WA.

Located approximately 260km east of Perth, it is Western Australia’s largest completed solar plant.

Its output of 274GWh of electricity annually generates enough green energy to power approximately 42,000 homes.

Through a PPA signed with BHP in February 2021, the solar farm also supplies BHP Nickel West’s Kwinana Refinery with 50MW of Merredin’s capacity until 2031, covering up to 50% of the refinery’s electricity use.

In doing so, the solar farm is making a major contribution to Western Australia’s greenhouse gas reductions.

Clean, Renewable Energy

The Merredin Solar Farm is located on 462ha of former farming and grazing country. The site is adjacent to the Western Power Merredin Terminal Substation and is connected to the substation at 220kV.

An 82MW diesel fired turbine power station and distribution substation are also located adjacent to the Merredin Terminal Substation on Robartson Road.

The solar farm consists of approximately 360,000 Risen Energy panels mounted on a single axis tracking system. 22 Inverter stations convert the power from the solar panels to alternating current (AC) before entering an onsite substation.

A transformer within this substation then increases the voltage for injection to the Merredin Terminal Substation, delivering clean, renewable electricity into the South West Interconnected System (SWIS).
