September heatwave in California: Sunday temperatures expected to hit 43°C (110F) in much of the state, 49°C (121F) in Palm Springs, and 51°C (124F) in Furnace Creek, Death Valley. Wildfire risk would seem high once more.
The Creek fire, one of many, grew to 570 km2 in just 4 days, and is still 0% contained. Expected containment date: 15 October(!). Tough times for @CAL_FIRE
This is incredible: 4 of California’s largest wildfires on record are burning right now! Three from the August wave still burning, one recent fire jumping into the top-10 too now.
(252,000 acres = 1,000 km2)
The August Complex fire has now become California's largest on record (1900 km² burnt), pushing the 2018 Mendocino fire into 2nd place.
And several fires merging have created the 1,000 km² Elkhorn fire, not too far away.
Those 5 ongoing Californian wildfires alone have now already burned 1.7 million acres (almost 7,000 km2). That’s 1.6% of California, and 1/6 of the total area of the Netherlands!

Starting a week-long business & pleasure trip to Spain, by train!
Hope to be in Barcelona this evening :)
I'll keep you posted in this🧵
The plan for today: Utrecht - Rotterdam - Paris - Barcelona. The tricky part is changing trains in Paris. Theoretically 2 hours should be more than enough to get from Paris-Nord to Gare de Lyon (the rail planner irresponsibly proposed 1 hour), but @Eurostar is often delayed (2/n)
Made it to Rotterdam, at least ;)
Bit very early, but hey, why hurry on a Saturday morning? (3/n)
Reading the Dutch "Action agenda congestion low-voltage grids".
The accelating energy transition already brings grid issues here. In the low-voltage distribution grid, the growing number of solar panels (PV), electric cars (EV) and (hybrid) heat pumps ((h)WP) is the challenge.
Without measures, a large and growing number of households would experience periods with too high or too low voltage (over- resp. onderspanning) or risk of grid failure.
Measures are categorized in: 1) accelerating grid expansion 2) more efficient use of the grid capacity 3) saving energy as much as possible.
1) already gets a lot of attention, and each of the three main DSOs plans to spend around €1 billion/year. Many hurdles though.
"Transition doesn't make energy cheaper, but to the contrary, significantly more expensive"
Headline in Dutch @Volkskrant yesterday, 9 days before the elections here. "Consumers and companies will pay 92% more for electricity and natural gas by 2030".
Hmm, let's look into that.
Firstly, as others have already pointed out too, it's a comparison between 2020 and 2030. In 2020, energy was cheap: Covid reduced demand, and Russia hadn't started its energy war and attack on Ukraine yet.
Compared with 2023, not a lot would remain of the "+92%".
Looking into the forecasted price increase 2020-2030 it has three components: 1. Tax (Belasting) +€5 billion. That'd be a political choice, which has little to do with the energy transition. 2. Grid (Netbeheer) +€5 billion. Increase to be expected indeed.
But ...
A problem for French nuclear power producer EDF: its total production cost (in the old power plants) is 60 €/MWh, according to the regulator, but govt forces it to sell a big chunk at 42 €/MWh.
60 €/MWh is not a bad cost in the current European electricity market, but it's also a reality check for those here who think nuclear power is practically for free after the investment in the power plant is done.
