Is anyone aware of good sources of higher resolution models? Hourly resolution like this model provides doesn’t help much now that energy markets have moved to 15-min and 5-min resolution.

* 90 degree day => more air conditioning usage => power goes up
* 70 degree sunny day => that's also July 4th (holiday, not a work day when factories or heavy industry are running) => lots of people go outside + it's a holiday => power consumption goes DOWN
* 10 degree difference colder/hotter => impacts resistance of power lines => impacts transmission congestion credits => impacts power prices
It's a fascinating industry. One power trading company that I consulted for had a meteorologist who was also a trader. They literally hired the dude from a news channel if I remember it correctly.
But knowing "there will be a massive drop in temperature between 1pm->2pm" doesn't help much anymore, you need to know which 15-minute or 5-minute block all those heat pumps will kick on in, to align with markets moving to 15-min and 5-min contracts.
Major forecasts like ECMWF don't have anything like that resolution; they model the planet at 3 hour time scale, with a 1 hour "reanalysis" model called ERA5.. hoping to find good info on what's available at higher resolution.
