Some notes on reporting carbon emissions using UK government standardised intensity factors, as well as more accurate approaches.

If you work with US energy system data we want to better understand your needs, frustrations, and use cases so we can improve the open data we publish. Fill out/share our short survey? It should take less than 10min. We're hoping to be able to get 100+ responses by the end of the month.
Anyone help be find some #energydata? Am looking for either spatial data for UK Gas Distribution Zones (LDZ) or a mapping of LDZ to Postcodes
E.g. https://www.arcgis.com/apps/mapviewer/index.html?webmap=1d827cecce05406dacf57887f076552c
...but a dataset with some provenance to it. Lots of Postcode-LDZ lookup services but no data/api
Any help? #opendata
We’ve launched a new data portal with fuzzy search, live data preview, and CSV export of up to 5M rows at a time! Check it out at
We've just published our latest annual report illustrating how schools are able to save money and reduce carbon emissions, often with little or no costs, when they have better access to their energy data.
All while educating children about climate change,

Everything is a lot right now. Want to tune it all out for ~10 minutes and help us better understand your energy data needs? We're kicking off our first (hopefully annual!) PUDL community survey. Please boost! Both current and possible future PUDL users encouraged.
A second post in which I share some of the things I've learned since working in the energy sector. This time looking at metering. #energy #energydata #datainfrastructure

Glad I posted this as it's prompted some useful discussion.
- different countries have different standard intervals. E.g. in Spain its 15 minutes not half-hour
- lol, timezones
- there's an API for UK calorific values for gas
Will update the post when I get chance.
We're doing our best to archive vital #energy system data before it gets scrubbed.
Thankfully this flaw isn't universal. We love doing maintenance! However... grant funders & clients don't always share our enthusiasm. So in 2025 we're evolving our funding model for PUDL.

GitHub announcement for the new PUDL v2024.10.0 data release. Please say hi if you're using it, or have any issues or questions!

If you work with energy data as part of your research, advocacy, or business or if you're an open source contributor who works in Python and cares about energy and climate issues, and you can spare 30 minutes to chat with us about it, we're using Calendly to schedule interviews. 5/5
Good data format design is a UX issue.
Some thoughts on why energy data is so inconsistent, and a short course outline for teaching how to design better data formats.

I think this is a new one for me in terms of terrible #energydata
Have been handed an XLSX file (sigh) where a key identifier is only available in the worksheet name (ffs!) but the kicker is a DateTime column that has been pre-formatted with a specific format string of "mm:ss.0". (wtf?!)
So you can't tell which half-hour of the day a row is for without manually reformatting the column.
Apparently the data provider is unable to change it 
Jacques de Calendar's GridEmissions project looks very useful! It take the nearly real-time EIA-930 electricity demand, generation, energy source, and interchange data and cleans it up to the point of being analysis ready on a continuous basis. The results are available for 30 days through an API with the full dataset available for bulk download.
A real-ish time map of emissions intensity by balancing area:
Hey #EnergyMastodon we have a new PUDL data release, including final data through 2022. This is our first *data only* release, with everything we produce written into the database. So there's no need to install our data processing pipeline software.
This is an important release if you currently rely on the PUDL DB, since we're about to rename a bunch of stuff.
Announcement with more details up in our GitHub discussions.

A question for the #energy #energydata and #heatpump experts.
Are there viable methods for estimating thermal/heat load for buildings based on half-hourly gas data plus some basic info (floor area, local temperature, degree days).
Looking for any useful write-ups that could be used to help assess sizing of a heat pump.
We're planning to do a bunch of outreach in 2024 in the community of people working with open data and open source energy system models (hopefully with support from NSF POSE and maybe Sloan) and it seems adjacent to the kind of work being done by @pyOpenSci & @leahawasser
Do y'all think this would be a good potential community partnership?
We made a post in their Discourse here:

A beautiful blog post about curtailment, with data and visualizations from CAISO, ERCOT, and SPP. From GridStatus:
