A roundup of energy and climate developments for September 19, 2026, with summaries, links, and commentary.
I. Policy and Energy Prices
1. Europe’s winter power market flashes its strongest warning since the energy crisis: German January power above €180/MWh (power prices)
Summary:
Bloomberg reported on September 19 that German wholesale power for January is trading above €180 a megawatt-hour on the European Energy Exchange, up more than 60% from a year earlier. The main drivers are higher natural gas prices, difficulty refilling storage, and the Iran war’s closure of the Strait of Hormuz, which has cut Qatari supply. Heat and strikes have curtailed French nuclear output, and hydro stocks are low. In a cold winter with Middle East supplies still constrained, wholesale prices could rise by as much as 50%, the report said. UK household energy bills are set to rise 25% in January, while Norwegian state subsidies would largely shield consumers. During the 2022 crisis, power prices exceeded €1,000/MWh, more than five times current January futures. Baringa analysis provided to Bloomberg found that without solar capacity added since 2021, average European wholesale prices this summer would have been about 30% higher.

Commentary:
Europe is better at importing LNG than it was in 2022, but winter power is still priced by gas, nuclear availability, and weather, and electrification makes that bill more political, not less.
2. Germany announces a €2.5 billion fuel-tax cut of about 17 cents a litre and aims for a price cap in early 2027 (policy)
Summary:
Politico reported on September 19 that the German government announced on Friday it will lower the tax on petrol and diesel by 17 cents per litre in a relief package worth €2.5 billion, to be implemented next month. France 24, citing people familiar with the decision, said the move includes a €0.14 cut in the energy tax and about €0.03 on the sales-tax side. The nationwide daily average for E10 gasoline hit a record €2.286 a litre this week as the Iran war pushed a benchmark oil price above $100 a barrel. Berlin also plans a temporary fuel-price cap, modelled on Luxembourg and Belgium and reflecting oil prices, distribution costs, and retail margins, by January 1, 2027 at the latest. Finance Minister Lars Klingbeil, speaking in Dublin, asked the European Commission for a windfall-tax proposal by the end of October. Economy and Energy Minister Katherina Reiche told Handelsblatt that such a tax would make sense only if prices were being abused, and that Germany’s 11 refineries must not be put at risk.

Commentary:
The tax cut can cool next week’s pump-price politics, but it does not change the fact that Europe is still paying for Hormuz risk, and the coalition is not even aligned on a windfall tax.
3. Brent settles near $104 a barrel as Saudi Arabia seeks a partial restart of the East-West pipeline within days (oil and gas)
Summary:
The Business Times reported on September 19, citing Bloomberg, that crude fell for a third straight session. The global benchmark Brent settled about 0.9% lower near $104 a barrel, locking in a narrow weekly loss. West Texas Intermediate, nearing expiration, settled around $100. Saudi Aramco is working to partially restart the East-West pipeline within days after drone strikes tied to the Iran war, and to restore full capacity within about six weeks. The line, a workaround around Hormuz, can move up to 7 million barrels a day. The kingdom is also selling more crude from outside the strait, but has told at least two European refining customers they will receive no crude next month. Differentials from the North Sea to the Mediterranean have surged to records. Brent is up about 70% this year. UK Maritime Trade Operations said it received a report on Wednesday of a tanker being struck by an unknown projectile while leaving the strait.

Commentary:
The price dip reflects a possible partial return of the Red Sea bypass, not a surplus; European refiners being cut off next month shows the physical market is tighter than the futures settlement.
4. US judge rules EPA illegally terminated the $7 billion Solar for All program (solar)
Summary:
The Associated Press reported on September 19 that US District Judge Mary McElroy in Rhode Island ruled on Friday that the Trump administration illegally terminated the $7 billion Solar for All program and vacated the termination. The program was intended to make solar accessible to more than 900,000 lower-income households. The EPA rescinded the funds in August 2025; Administrator Lee Zeldin had called the program a boondoggle. McElroy wrote that Congress clearly intended the agency to keep administering grants already obligated, and that the EPA acted contrary to that intent without other statutory authority. The EPA said Friday it is reviewing the decision and considering an appeal. The Southern Environmental Law Center said that when the EPA awarded the $7 billion in 2024, the agency estimated the program would save families $350 million a year on electricity bills, at least $8 billion in total, and support 200,000 jobs and training places. Solar for All is part of the $27 billion Greenhouse Gas Reduction Fund created in the 2022 climate law.

Commentary:
The ruling pulls already-obligated money back from an administrative cancellation, but with an appeal under consideration, communities still do not know whether the funds arrive before this heating season.
II. Renewables and Storage
5. Renewables top 80% of demand on Australia’s main grid for the first time, while large volumes of wind and solar are curtailed (renewables)
Summary:
RenewEconomy reported on September 19 that at 12:25 p.m. Saturday, renewables reached 80.5% of demand on the National Electricity Market (another data source put the share at 81.5%), breaking the previous day’s record of 79.6%. Rooftop solar was meeting more than half of demand, and coal’s share was pushed down to 18.8%, close to the floor at which coal plants prefer not to switch off. More than half of available wind output and nearly half of large-scale renewable output were curtailed, both because plants chose not to run at negative prices and because of congestion or maintenance. Grid analyst Geoff Eldridge said that by 1:50 p.m. AEST the market had already curtailed about 54.8 GWh of renewable energy, while flexible loads absorbed about 22.5 GWh, including about 17.3 GWh into batteries and 5.2 GWh into pumped hydro. In the first interval above 80%, batteries were charging at about 4.5 GW and another 8.4 GW of available renewable output was curtailed.

Commentary:
Crossing 80% does not show coal has exited; the same interval combined charging, curtailment, and coal stuck near minimum load, which means the shortage is flexibility and system security, not another midday solar record.
6. German study: batteries at substations could allow about 150 GW more solar (storage)
Summary:
The German press agency dpa reported on September 19 that a study commissioned by the solar industry association BSW from the Fraunhofer Institute for Energy Economics and Energy System Technology finds that intelligent batteries at 1,313 rural, renewables-heavy substations could allow up to about 150 GW of additional photovoltaic capacity on existing transformers, more than Germany’s roughly 130 GW already installed. The association said a substation could connect more than twice the transformer’s rated renewable capacity, and that only about 1% of the extra solar energy would have to be curtailed on an annual average because of transformer limits. Researchers first analysed 2025 operating data from 20 transformers at 13 substations, then extrapolated to those 1,313 sites. BSW funded the study. It estimates the approach could save billions of euros in grid investment, and wants the grid package now before the Bundestag not to label large areas as congestion zones that would stall further renewable build-out. The study does not cover upstream high-voltage constraints, land, or permits.

Commentary:
This is a technical-potential estimate that nameplate addition should not be the connection test; turning it into 150 GW still requires changing the incentive that pays grid operators for capital expenditure.
7. Zhejiang sets market rules for grid-side standalone storage: 40 projects, 2.54 GW, and no capacity payment (storage)
Summary:
Solarbe reported on September 19 that Zhejiang’s development and reform commission, energy bureau, and energy regulator recently issued rules for grid-side standalone storage to join the power market. A project list published on September 15 covers 40 projects totalling 2.54 GW / 5.1 GWh. Twenty-eight projects already in commercial operation and under provincial dispatch, totalling 2.13 GW, may join the spot energy market and frequency regulation, but a dispatch unit must choose one or the other on a given day, and frequency bids must be at least 60% of installed capacity. Six commercially operating projects outside provincial dispatch, totalling 0.11 GW, may trade only in the spot market. Six projects not yet in commercial operation, totalling 0.3 GW, stay out for now. Through the end of 2026, units submit a 96-point self-schedule and settle as price-takers at the 220 kV nodal price; from January 1, 2027, they are to bid quantity and price. Network charges and government funds are levied on net energy. Existing retail contracts must be terminated and filed by September 20, or market status lapses on October 1. The rules include no capacity payment.

Commentary:
Zhejiang is moving storage from policy backstops to a daily choice between spot spreads and frequency payments, and without a capacity price, being on the list is not the same as earning a return.
III. Climate and Disasters
8. Typhoon Dujuan nears Honshu; weather agency warns of landslides and floods, with possible landfall in Chiba on September 21 (extreme weather)
Summary:
The Star reported on September 19, citing the Japan Meteorological Agency, that Typhoon Dujuan was south of Honshu by mid-afternoon, moving northwest at 15 km/h, with central pressure of 975 hectopascals and maximum gusts of 162 km/h. The storm may make landfall on the Boso peninsula in Chiba prefecture, east of Tokyo, on September 21, the second day of a five-day holiday. The agency warned of landslides, flooding in low-lying areas, strong winds, and high waves from western to northern coasts over the next several days. Rainfall in the 24 hours through noon on September 20 is forecast to reach 150 mm in the Izu islands and the Kanto-Koshin region, including Tokyo, and about 60 mm in Tohoku and Tokai. JR East said some train services in Chiba and other prefectures may be suspended from late September 20 through September 21. The Asian Games opened in Nagoya on September 19, with venues in Aichi and also in Tokyo.

Commentary:
The operational risk is the overlap of a holiday travel peak and a possible landfall east of Tokyo; suspended trains will disrupt the city before the gust figures do.
9. Flash flood on the Navajo Nation kills three; the president declares a state of emergency (disaster)
Summary:
The Associated Press reported on September 19 that a flash flood on Tuesday near Newcomb, New Mexico, killed three people: Elsie Begay, her granddaughter Lucy Allison Mike, and Dora Franklin, a friend who had come to help. A late-season surge of monsoon moisture brought heavy rain to the Four Corners region; flooding this week damaged roads and forced evacuations. Navajo Nation President Buu Nygren declared a state of emergency on Friday. Some communities remained isolated by standing water and road damage, and multiple roads were still closed. Navajo police said three families in Shiprock, New Mexico, were evacuated Friday evening because of rising water near the San Juan River. About 40 miles south of Newcomb, in Mexican Springs, many dirt and gravel roads were impassable, and the local chapter house was converted into a temporary shelter.
Links:
Commentary:
This is not urban flooding that can be tallied after the water drops; once dirt roads are washed out, rescue and supplies are stranded outside the community.
Today's Summary
- Europe’s story is the bill: German January power futures are above €180/MWh, Berlin announced a €2.5 billion fuel-tax cut, and Brent still settled near $104 a barrel.
- A US court vacated the EPA’s termination of $7 billion in low-income solar funding, but the agency is considering an appeal, so delivery to communities is not assured.
- Australia’s main grid topped 80% renewable supply for the first time and curtailed large volumes at the same time; a German study and Zhejiang’s market rules both ask how storage gets connected and paid.
- Typhoon Dujuan may make landfall in Chiba on September 21, and a Navajo Nation flash flood has killed three people and triggered a state of emergency.
Daily Framing:
Today in the energy and climate cycle was a day when fossil bills collided with the absorption bottleneck — tax cuts and futures prices showed gas and oil still pricing Europe, while Australian curtailment, the German substation-storage estimate, and Zhejiang’s market rules showed the next test is whether the system can take the power, not another capacity headline.
