Solar Beats Coal For One Brief Moment In Australia
It only lasted for a few minutes, but for a brief time last Sunday, electricity from solar provided more electricity to Australia’s national energy grid than electricity from coal-fired generating stations. Just after noon, 9,427 megawatts (MW) of electricity came from solar, while only 9,315 MW came from burning coal.
Granted, there were several factors that had to align to make that happen. First, it was a sunny day in Australia. Second, it was a Sunday when demand is typically lower than during the week. Three, it came during a time of year when demand for heat or air conditioning is low. But whatever the reason — or combination of reasons — it was a milestone and a portent of things to come in the Land Down Under, where electricity from coal has been king since 1890 when the Yallourn Power Station began operating in the state of Victoria.
Dylan McConnell, a research fellow at the University of Melbourne’s climate and energy college, told The Guardian that for those few minutes, renewable energy represented 57% of national electricity generation. “This is what I unofficially call ‘record season’,” McConnell said. “It’s actually still pretty early in the season [to get these numbers] but in spring or the shoulder seasons you have the combination of low demand, because there’s no heating or cooling, and then nice weather on the weekend. Those factors combine and you get these giant shares of renewable energy that generally push out coal.” He added the event was only “fleeting” and that “Australia was a long way from peak renewable energy.”
From 8:30 am until 5:00 pm on Sunday, energy prices in Australia went negative. Although the exact price differed by jurisdiction, it meant energy consumers were being paid to use electricity and energy producers were paying to keep their generators spinning. Unlike solar and wind producers, coal generators are particularly hard hit when prices turn negative. The costs associated with shutting down and restarting coal generators are prohibitive, meaning operators choose to keep them running even at a loss.
According to data tracking service NEMlog, South Australia had 100% of its energy needs met by wind and solar, while Victoria would have met 102% of state demand had operators not been forced to switch off during the period of negative prices. Energy analyst Simon Holmes à Court said the overall proportion of renewable energy — solar, wind, and hydro — would have been higher in the energy mix, but wind producers chose to shut down to avoid the price hit.
“There was a significant amount of curtailment,” he said. “What it shows is that there’s already more renewables that could have gone into the grid if the coal plants were more flexible and transmission was upgraded.”
A Tipping Point For Australia?
The Clean Energy Investor Group — an 18-member body that advocates for investors in large-scale renewable energy projects — is advocating for financial reforms to “align Australia with international markets” and unlock new investment.
Simon Corbell, chief executive of CEIG, said governments and regulators should bring Australia’s investment guidelines into line with global markets. “Clean energy investors currently face significant risks in the NEM, which is holding back the capital needed. To unlock an investment pipeline worth $70 billion, we need effective market reforms and policy certainty, which could also save up to $7 billion in capital costs or up to 10% of the cost of Australia’s clean energy transition.”
Modelling conducted for CEIG by Rennie Partners found that Australia needs 51 gigawatts (GW) of renewable energy generation by 2042 if it is to meet its commitments under the Paris Climate Change agreement. So far, only 3 GW of new wind and solar projects have been committed, leaving a significant shortfall of 48 GW.
The sclerotic federal government led by fake Christian Scott Morrison has hardly lifted a finger to bring more renewables to the Australian continent and shows zero signs that it even understands, much less cares about, the advancing global warming crisis that is bringing fires, floods, drought, and heat waves to Australia and large sections of the rest of the world. Perhaps someday Australians will elect a real leader, one who will deal with reality rather than religious fantasies.

Japanese equipment giant Kubota brought 22 new or updated machines to the 2025 bauma expo earlier this year, but tucked away in the corners was a new retrofit kit that can help existing customers decarbonize more quickly, and more affordably.
No matter how badly a fleet may want to electrify, harsh economic realities and the greater up-front costs typically associated with battery electric remain high hurdles to overcome, but new retrofit options from major manufacturers are popping up to help lower those obstacles.
The latest equipment maker to put its name on the retrofit list is Kubota, who says its kit can be installed by a trained dealer in a single day.
That’s right! By this time tomorrow, your diesel-powered Kubota KX019 or U27-4 excavator (shown) could be fitted with an 18 or 20 kWh li-ion battery pack and electric drive motors and ready to get to work in a low-noise or low-vibration work environment where emissions are a strict no-no. Think indoor precision demolition or historic archeological excavation.
Then, if necessary, it can go right back to diesel power.
From diesel to electric and back again
If that sounds familiar, that’s because we’ve talked about a similarly flexible power solution from ZQUIP. The battery packs and diesel engines are much larger in that application, but the basic sales pitch remains the same: electric when it benefits your operation, diesel it doesn’t.
Kubota says its modular retrofit kits is a response to the increasing global demand for sustainable alternatives by focusing on making machinery that’s flexible and repairable enough to be “reusable,” and offer construction fleet managers a longer operational lifespan, superior ROI (return on investment), and lower TCO (total cost of ownership) than the competition.
Kubota’s solution also notably reduces maintenance costs and operational overheads. With no engine and associated components, servicing time and expenses are considerably reduced, saving customers both time and money. Additionally, with electricity costing far less than fossil fuels, it offers a highly economical advantage.
International Rental News reports that other changes to the excavators include a more modern cab controls with a digital instrument cluster, a 60 mm wider undercarriage for more stability, and an independent travel circuit allows operators to use the boom, dipper, bucket, and auxiliary functions without an impact on tracking performance.
Kubota’s new kit, first shown at last year’s Hillhead exhibition in the UK, will officially be on sale this summer – any day now, in fact – though pricing has yet to be announced.
Electrek’s Take
If you’re wondering how it is that we’re still talking about bauma 2025 a full quarter after the show wrapped up, then I haven’t done a good enough job of explaining how positively massive the show was. Check out this Quick Charge episode (above) then let us know what you think of Kubota’s modular power kits in the comments.

FERC: Solar + wind made up 96% of new US power generating capacity in first third of 2025
Solar and wind accounted for almost 96% of new US electrical generating capacity added in the first third of 2025. In April, solar provided 87% of new capacity, making it the 20th consecutive month solar has taken the lead, according to data belatedly posted on July 1 by the Federal Energy Regulatory Commission (FERC) and reviewed by the SUN DAY Campaign.
Solar’s new generating capacity in April 2025 and YTD
In its latest monthly “Energy Infrastructure Update” report (with data through April 30, 2025), FERC says 50 “units” of solar totaling 2,284 megawatts (MW) were placed into service in April, accounting for 86.7% of all new generating capacity added during the month.
In addition, the 9,451 MW of solar added during the first four months of 2025 was 77.7% of the new generation placed into service.
Solar has now been the largest source of new generating capacity added each month for 20 consecutive months, from September 2023 to April 2025.
Solar + wind were >95% of new capacity in 1st third of 2025
Between January and April 2025, new wind provided 2,183 MW of capacity additions, accounting for 18.0% of new additions in the first third.
In the same period, the combination of solar and wind was 95.7% of new capacity while natural gas (511 MW) provided just 4.2%; the remaining 0.1% came from oil (11 MW).
Solar + wind are >22% of US utility-scale generating capacity
The installed capacities of solar (11.0%) and wind (11.8%) are now each more than a tenth of the US total. Together, they make up almost one-fourth (22.8%) of the US’s total available installed utility-scale generating capacity.
Moreover, at least 25-30% of US solar capacity is in small-scale (e.g., rooftop) systems that are not reflected in FERC’s data. Including that additional solar capacity would bring the share provided by solar + wind to more than a quarter of the US total.
With the inclusion of hydropower (7.7%), biomass (1.1%), and geothermal (0.3%), renewables currently claim a 31.8% share of total US utility-scale generating capacity. If small-scale solar capacity is included, renewables are now about one-third of total US generating capacity.
Solar is on track to become No. 2 source of US generating capacity
FERC reports that net “high probability” additions of solar between May 2025 and April 2028 total 90,158 MW – an amount almost four times the forecast net “high probability” additions for wind (22,793 MW), the second-fastest growing resource. Notably, both three-year projections are higher than those provided just a month earlier.
FERC also foresees net growth for hydropower (596 MW) and geothermal (92 MW) but a decrease of 123 MW in biomass capacity.
Taken together, the net new “high probability” capacity additions by all renewable energy sources over the next three years – i.e., the bulk of the Trump administration’s remaining time in office – would total 113,516 MW.
FERC doesn’t include any nuclear capacity in its three-year forecast, while coal and oil are projected to contract by 24,373 MW and 1,915 MW, respectively. Natural gas capacity would expand by 5,730 MW.
Thus, adjusting for the different capacity factors of gas (59.7%), wind (34.3%), and utility-scale solar (23.4%), electricity generated by the projected new solar capacity to be added in the coming three years should be at least six times greater than that produced by the new natural gas capacity, while the electrical output by new wind capacity would be more than double that by gas.
If FERC’s current “high probability” additions materialize, by May 1, 2028, solar will account for one-sixth (16.6%) of US installed utility-scale generating capacity. Wind would provide an additional one-eighth (12.6%) of the total. That would make each greater than coal (12.2%) and substantially more than nuclear power or hydropower (7.3% and 7.2%, respectively).
In fact, assuming current growth rates continue, the installed capacity of utility-scale solar is likely to surpass that of either coal or wind within two years, placing solar in second place for installed generating capacity, behind only natural gas.
Renewables + small-scale solar may overtake natural gas within 3 years
The mix of all utility-scale (ie, >1 MW) renewables is now adding about two percentage points each year to its share of generating capacity. At that pace, by May 1, 2028, renewables would account for 37.7% of total available installed utility-scale generating capacity – rapidly approaching that of natural gas (40.1%). Solar and wind would constitute more than three-quarters of installed renewable energy capacity. If those trend lines continue, utility-scale renewable energy capacity should surpass that of natural gas in 2029 or sooner.
However, as noted, FERC’s data do not account for the capacity of small-scale solar systems. If that’s factored in, within three years, total US solar capacity could exceed 300 GW. In turn, the mix of all renewables would then be about 40% of total installed capacity while the share of natural gas would drop to about 38%.
Moreover, FERC reports that there may actually be as much as 224,426 MW of net new solar additions in the current three-year pipeline in addition to 69,530 MW of new wind, 9,072 MW of new hydropower, 202 MW of new geothermal, and 39 MW of new biomass. By contrast, net new natural gas capacity potentially in the three-year pipeline totals just 26,818 MW. Consequently, renewables’ share could be even greater by mid-spring 2028.
“The Trump Administration’s ‘Big, Beautiful Bill’ … poses a clear threat to solar and wind in the years to come,” noted the SUN DAY Campaign’s executive director, Ken Bossong. “Nonetheless, FERC’s latest data and forecasts suggest cleaner and lower-cost renewable energy sources may still dominate and surpass nuclear power, coal, and natural gas.”
