350MW Lower Wonga Solar Farm in Gympie greenlit.

In April this year, we reported on a Gympie solar farm which lodged a $2b development proposal with the council. Today we are pleased to announce that the 350MW Lower Wonga Solar Farm has been greenlit by the Gympie Regional Council via a unanimous vote and should commence construction within the next few months.

The Lower Wonga Solar Farm, located on 572 hectares adjacent to a high voltage substation in Lower Wonga, will output 350MW (nominal, AC) via around 1.3 million solar PV panels, according to its website. However, an article by Arthur Gorrie at the Gympie Times notes that it will use 2 million panels. We have reached out to Solar Q, the developers of the project, to advise which is correct and will update you when we hear back.

In any case, Gympie Mayor Mick Curran told Wednesday’s council general meeting the solar electricity plant would be the largest in Australia. This record probably won’t last for long the Bulli Creek Solar Farm in Millmerran will generate 2000MW over 5400 acres and was greenlit by the Federal Government last week. 

Solar Q plan to increase the plant’s renewable energy generation from 350MW to 800MW in 2021 via a three-stage construction process over the next four years. 800MW is enough electricity to power 315,000 homes.  They are also planning to include battery storage, which will make it one of Australia’s biggest solar generating plants. It’ll reduce carbon emissions of around 666,700 tonnes of co2, which is the equivalent of getting 180,000 cars off the road! 

Scott Armstrong, Managing Director of Solar Q,  was quoted as saying “The whole aim with an energy plant is to be as close as possible to the customers, so you reduce energy transmissions losses and costs. “But we are also close to a workforce. We don’t need fly in-fly out, we have Gympie,” he said.

Great to see them supporting local employment – the farm is expected to create 450 full-time construction jobs for the 18 months of construction, 12 permanent positions, and result in the creation of major business opportunities for the Gympie region. The high voltage substation will be able to sustain transmission to Gin Gin, Teebar Creek, Mungar, Kilkivan region, Gympie region, Palmwoods/Sunshine Coast, and Brisbane areas. 

We’ll be sure to post an update as soon as we have any more information about this exciting new development.

Darling Downs Solar Grid Risks

A substantial rise in solar PV farms on the Darling Downs risks causing major issues with energy supply networks if urgent grid updates are not undertaken to ensure the Darling Downs solar grid is future-proofed.

Darling Downs Solar Grid

According to The Chronicle, six projects worth almost $2 billion are planned for the Darling Downs region over the next few years. This includes a 5000-hectare plant at Millmerran (the largest solar farm in Australia), and the $200 million, 100MW Yarranlea solar farm.

State Minister for Energy, Biofuels and Water Supply Mark Bailey told the Toowoomba and Surat Basin Enterprise National Energy Summit “at this stage” the Queensland Government don’t have any grid upgrades for the Toowoomba area planned – noting that they have upgraded the transmission line in North Queensland “because we’ve got so many projects happening there.” Bailey said that “…we will continue to review our system to make sure we can facilitate these projects.”

Federal Minister for Resources Senator Matthew Canavan was also drawn into the conversation, advising that we should be careful with the amount of renewable energy we source if we don’t have a clear path forward with regards to grid stability: “We shouldn’t push renewables up above 40% without a proper plan of knowing how to keep the lights on when renewables are not there,” he said. “That’s what they did in South Australia and they put their own state and businesses there at great risk.”

The Chief Executive of Yarranlea Solar, Nick Canto, said that “major infrastructure upgrades” were required as the existing grid will not have the capacity to deal with the increased power load. Canto was also quoted on the 11th discussing Toowomba and the Surat Basin’s ‘extensive electrical transmission network’ – so it looks like he’s more worried about the grid’s ability to deal with such a large amount of renewable energy from multiple solar farms.
