Australia Electricity Emissions June Update: Average NEM emission intensity over last 12 months: 521 kg CO2-e/MWh. Down 23% since 2020, down 38% since 2015 Sth Australia reductions leading the way thanks to its increase in wind & PV generation. Down 31% since 2020, 69% since 2015.

Australia's main electricity grid, the NEM, has long had flexible gas and hydro to help manage the highly variable supply-demand balance. Now storage (mostly batteries) is rapidly growing & will soon be the main source of flexible supply.

Here are some stats from Australia showing just how much rooftop PV has reduced peak demand. Utility renewables have also performed very well on these occasions. bsky.app/profile/davi...

Another interesting stat. Eyre has a weather station & has recorded some extraordinary temperature variability. It had a min of -2.1 deg C on 14 Nov 2016, then 2 days later on Nov 16 had a max of 44 deg C! A friend of mine happened to be camping there at the time.

The London Ambulance Service responded to the highest number of life-threatening emergencies in its history yesterday. The Chief Executive said this was "driven by the extreme heat across London".

Yesterday (Sunday) saw the worst 1-day wind drought in over 2 years on Australia's NEM. Just 24 GWh of wind generation, the lowest since 13 June 2024 (16 GWh) But PV generation was OK. Yesterday's VRE total (wind+utilityPV+rooftopPV) of 105 GWh was better than the 82 GWh total on May 18 last month

The co-presidents of COP 31 have announced a target of 35% electrification as a percentage of Final Energy. Electrification is absolutely the right target, but percentage of Final Energy is the wrong metric. What we really need is data on Useful Energy! mliebreich.substack.com/p/lets-targe...

Global CO2 emissions have plateaued since 2013, leading to a slower growth in atmospheric CO2 than would have otherwise been the case. In a new analysis at The Climate Brink, I've taken look at what would have happened if emissions had continued to grow: www.theclimatebrink....

Huge potential for Commercial & Industrial PV+storage to help Australia decarbonise electricity quickly Offers: -rapid build with minimal environmental issues or need for new transmission - better alignment with demand & higher CF than residential PV. Important report /ht @adenisryan.bsky.social

After the record BEV market share in April, there is now yet another record month for BEV market share in May. China is truly lost to anyone trying to to sell cars with a fossil fuel engine.

Record BEV month in Australia, and by far!

For the Australians, but also others interested in this issue: Australia's emissions data just saw its *biggest ever* land-use data revision. Except this time, it's UPWARDS: the same amount as power sector GHGs fell 2018->2026 (!!!!!) A thread on that + other updates from the data!

Great news. And Canberra leading the way with EVs and plug in hybrids exceeding 45%

A milestone achieved on Australia's main electricity grid, the NEM. Energy discharged from utility batteries over the last 12 months now exceeds generation from peaking (OCGT) gas turbines. Those who thought batteries would only provide ancillary services now looking foolish.

99% of electricity supply interuptions on Australia's NEM in FY2025 were due to faults on the distribution (95%) & transmission (4%) network. Distributed local renewable generation paired with islanding capable storage is a great way to be resiliant to the vast majority outages.

Global sales of combustion engine cars peaked in 2017— To decarbonize road transport, the world must move away from petrol and diesel cars towards electric vehicles and other forms of low-carbon transport.

Uruguay is currently number 5 fastest transitioning country in my portfolio, neck to neck With Thailand, Singapore and Denmark in 3rd, 4th and 6th.

How bad was Monday's wind+solar drought on Australia's NEM? Simple analysis suggests it was the worst 1-day VRE drought since 2022. Normalised VRE generation on May 18 was 34% (ie, 66% below average), and the previous day May 17 was also terrible at 44%. Previous record low was 37% on 4/7/2023.

Two things can be true: • RCP8.5 was never a realistic "business as usual" scenario • The world has made real progress bending the emissions curve down Glen Peters, Piers Forster, and I explain in a new article: www.theclimatebrink.... 1/11

China's transition to BEV is simply amazing, even more so if you consider the size of their market. Big markets usually have it harder, but China is still among the fast countries to transition.

The transition away from petrol & diesel cars towards BEV & PHEV cars is accelerating in Australia. Sone nice charts and analysis for many countries via @leraffl.bsky.social

An amazing amount of residential batteries were installed in Australia in April (~2.5GWh). These batteries were heavily subsidised by the government & most were very large (> 40kWh). Given low VPP uptake rates, there's a risk that many will be underutilised. Here's an idea to avoid that:

Impressive EV growth in Canberra. In April, 33% of newly registered vehicles were pure battery electric. Add plug-in hybrids and the total rises to ~44%. Every driver who switches from petrol/diesel to EV frees up more fuel for those who haven't, improving Aus fuel security. /1

Within a few years, the NEM will have 45GW/200GWh of storage, excluding anything from Snowy2.0. My weekly simultion assumes much less than this - 24GW/120GWh & reaches 98% renewable. By FY2040 the 2026 Draft ISP assumes 44GW/202GWh of storage excluding Snowy2.0 & is 96% renewable. /1

NEW: Falling fossil everywhere: For the first time in 2025, fossil electricity generation fell in EVERY OECD country, compared to its peak. Solar and wind are helping the power sector to transition away from fossil fuels #TAFF

From my reading of the CER data, the Cheaper home batteries program total at the end of March was 7.4 GWh. If it is now at 10 GWh, then that would imply 2.6 GWh of batteries installed in April! That's about twice the previous biggest month (Dec 2025 with 1.3 GWh installed)
