Australia's Wind and Solar Decisions Have Already Passed 5,358 Megawatts
Australia's Clean Energy Regulator recorded 5,358 megawatts of utility-scale wind and solar investment decisions by 30 September 2026, already above every full year on its table.
The Clean Energy Regulator's table is ahead of every full year on it. The turbines are not all built.
The Clean Energy Regulator updated its large-scale renewable energy tables on 14 October 2026. One row is the story. Utility-scale wind and solar that reached a final investment decision in 2026, counted from 1 January through 30 September, stands at 5,358 megawatts. On the same table, the highest previous full year was 4,884 megawatts, in 2018. 2025 managed 2,124. The year is not over.
Chris Bowen, Minister for Climate Change and Energy, put a press note out on 15 October. He said 2.1 gigawatts reached a final investment decision in the September quarter alone, matching the strongest quarter on record, and described that slice as enough to power about 1.2 million homes. Wind was 1.1 gigawatts of the quarter, the highest wind quarter the series has. Solar was 1.0 gigawatt, after 2 gigawatts of solar decisions in the second quarter. Solar decisions for 2026 so far are 3.5 gigawatts, which his office called about 30 percent above the previous annual solar record. His rounded year-to-date figure is 5 gigawatts, against a previous full-year record he put at 4.9. The regulator's unrounded wind-and-solar cell is 5,358 megawatts. Both can be true. One is a speech. One is a cell.
Households are in the same release, and they are a different ledger. Approved capacity under the Cheaper Home Batteries program was 15.3 gigawatt-hours at the end of September, up from 5.0 at the end of 2025. Including batteries installed before the scheme, Bowen put the national home-battery fleet around 19 gigawatt-hours, more than five times the stock when the scheme began. New South Wales accounts for 5.6 gigawatt-hours of approved home batteries. Victoria and Queensland are about 3.2 each. Another 1.9 gigawatt-hours was approved in the quarter. About half the approved batteries are retrofits on existing solar. Rooftop solar added 90,042 systems and 894 megawatts in the quarter, 35 percent more capacity than the same quarter of 2025. Year-to-date rooftop additions are 2.8 gigawatts.
A final investment decision is a board signing a cheque, not a turbine already spinning. The regulator says it tracks public announcements, the list may be incomplete, and figures can be revised. Ian Learmonth, the former head of the Clean Energy Finance Corporation, has said the national 2030 target implies about 29 gigawatts of new large-scale renewable generation, or about 6.3 gigawatts a year. A record year that is still under that pace is a record and a shortfall at the same time. Bowen also said renewables generated more electricity than fossil fuels in the national grid last month. That is his statement. It is not a line this desk re-derived from the market operator's five-minute data.
Key Facts
- Clean Energy Regulator table, updated 14 October 2026: 5,358 MW utility-scale wind and solar FID, January to September 2026
- Previous full-year high on that table: 4,884 MW in 2018
- Bowen, 15 October: 2.1 GW FID in the September quarter, including 1.1 GW wind and 1.0 GW solar
- Solar FID in 2026 so far: 3.5 GW
- Cheaper Home Batteries approved capacity: 15.3 GWh at end of September, from 5.0 GWh at end of 2025
- Rooftop solar in the quarter: 90,042 systems, 894 MW

Why This Matters
Investment decisions are how a grid actually changes, and they are easy to fake with a groundbreaking photo. This one has a regulator row. It also has a former public financier's annual pace sitting above the record. Both sentences belong in the piece.
What We Don't Know Yet
How many of the 5,358 megawatts will be delayed, resized, or cancelled. Connection queues and transmission are not in the FID cell. The "more than fossil fuels last month" line is the minister's, not an independent recount here. Home-battery approvals are not the same as batteries already installed and commissioned.
