Poland recorded 300+ hours of negative prices in 2025. Coal still sets marginal prices, but solar at midday peaks 12 GW. Battery storage operators are seeing unprecedented revenue signals as renewables reshape this single-zone market faster than anyone expected.

GB Solar output hit 14 GW on the 8th of July. For several hours, that's more than gas, wind, and nuclear combined. But, capture rates are falling fast across Europe.

Skeptics of waterfront street redesigns will say "we aren't Paris." You can remind them that Paris wasn't always Paris.

It's worth remembering how quickly the UK media buried the story of Tesla deciding to build its mega factory in Germany and not the UK precisely because of Brexit. A €4 billion investment lost to Britain along with 11,500 jobs. en.wikipedia.org/wiki/Gigafacto…

😬UK gas prices just hit highest level since 2022😬 At current prices… * New wind & solar from latest "AR7" auction would cut the bill for UK gas imports by £5.5bn/y * A single (1) home heat pump would cut bill for gas imports by more than £600/y

I shared Ginger Wildheart's tweet with his medical update (and his response to it) earlier. Fair to say I'm gutted. He's up there as one of the most important musicians in my life, from soundtracking formative moments, offering catchy yet meaningful tunes, providing great gigs, >

Hive mind: Has anyone seen (ideally recent) data on the marginal fuel in European countries? The Zakeri and Staffell paper from 2023 gets cited a lot but it's from a few years ago, data for 2021

Copernicus Marine data is powering the next generation of AI-based ocean forecasting. At a @defis_eu workshop in Brussels 🇪🇺 this week, @MercatorOcean presented GLONET, an ocean forecasting model trained on Copernicus Marine data, and OceanBench, an open framework for benchmarking AI models against ocean physics. Both are now accessible via the #EUDigitalTwinOcean @edito_dto Read more: events.marine.copernicus.eu/artificial-int… #CopernicusMarine #OceanForecasting #ArtificialIntelligence #EUDigitalTwinOcean #EUSpace

The production of ERA6, coming up in 2027, has started. The next‑generation climate reanalysis from #CopernicusClimate will offer >2× finer resolution than ERA5, a coupled ocean–atmosphere–wave model, improved data access & more. Read more: climate.copernicus.eu/copernicus-cli… @ECMWF

The Night Iran welcomed Frank Sinatra before the Islamic Regime shut the music down forever, 1975

Norway - sells oil & gas, but uses electricity mainly from renewables. 97% of new cars are electric and heat pumps are main source of heating. They're barely affected by what's happening in Iran. Their electricity costs going up 17%, ours going up 60% because we are so much more dependent on gas.

Not good news 🗞️ 👇 Renewables, biofuels, fuels, and retrofitting so important to Europe.

Amsterdam to Milan sounds epic!

At 11:00 CET, several Central and Eastern European markets cleared at €0/MWh, while Spain was at -€1.47/MWh. The main driver was strong renewable generation during relatively soft demand hours. ▪️In Spain, high wind and solar output pushed supply above local demand, resulting in negative prices. ▪️In parts of CWE and CEE, supply was sufficient to clear the market at the €0 floor. ▪️Cross-border capacity was available, so the outcome reflects overall system balance rather than congestion. ▪️We saw voluntary renewable curtailment in the day-ahead auction contributing to the price stability, with assets not coming online at zero prices in several countries. ▪️French nuclear contributed with 9 GW downward flexibility. ▪️Balancing and intraday markets consistently saw negative prices.

Incredible figure

Shocked when someone told me that price of solar+storage is now so low that a standalone storage+pv system could compete with gas turbine in terms of 24/7 power cost. Something I thought was basically off the table due to limitations in storage technology. Things are changing..

@Natural_Power Great acquisition - Ollie is a star!

We are pleased to welcome Ollie Tulloch PhD CEng to help strengthen out advanced performance engineering capabilities. He has strong experience in applying advanced engineering and analytics to operational challenges across the full project lifecycle: hubs.ly/Q044NTJx0

@DundeeSat I learned F90 during my PhD, I’d failed every coding module I’d ever sat up until that point (tho I had re-coded an entire assembly line as well).

But he'll never take our... #FORTRAN...

@SpencerHakimian I think part of it is bc autistic people tend to be very disruptive & un constrained in their thought process. Which doesn’t really lend itself to corporate career progression (except maybe at the tippy top).

Why are so many Billionaires Autistic?
