One of Australia’s largest solar farms, with more than 750,000 solar modules generating 255 MWdc of electricity, has come to life. The project is majority owned by UK-based infrastructure investor John Laing with Australian-based Maoneng holding the rest.
The project’s registration approval is expected to help Maoneng progress with its plan to develop four large-scale 50 MW/100 MWh batteries for Australian power producer, AGL. One of the planned batteries to be located next to the Sunraysia solar farm, with AGL contracted to take half of the solar farm’s output.
The utility-scale batteries are expected to be operational from 2023, coinciding with closure of the Liddell coal-fired generator, and will store enough energy to power up to 30,000 thousand homes, providing 200 MW/400 MWh of dispatchable capacity to AGL between 2023 and 2038.
The Energy Storage Development Agreement builds on the 300 MW solar offtake which AGL signed with Maoneng in December 2017 to procure renewable energy from generators developed by Maoneng including 200MW from other solar plants yet to be built.
Cost of delays
, and was one of a number of solar projects to be badly affected by , located on a particularly troubled part of the grid.
With losses of over GBP43 million ($75 million) from its two Australian solar assets – the Finley and Sunraysia solar farms in the first half of this year, John Laing has decided against making any new investments in Australian renewables. The UK-based infrastructure investor is not alone in its decision to pull out of the Australia sector, with .
The delays in production at Sunraysia have cost not only John Laing, but also EPC contractor, Decmil. over delays. Inverter providers Schneider Electric also become embroiled in the legal claims relating to the projects.
