Carbon Intensity Data Providers

[bvickers7]

Hi All!

We are evaluating different providers of carbon intensity data to use as inputs to SCI calculations. We are immediately interested in historical data but may be interested in forecasting in the future to do things like demand shifting. As far as we can tell the main options are:

• https://watttime.org/
• https://www.electricitymaps.com/
• https://singularity.energy/open-grid-emissions

We've also considered implementing something ourselves that calculates US grid intensity from within an IF plugin.

Has anyone done a comparison across these? Just browsing the websites I can see there are some differences in pricing, coverage, and possibly methodology. I also see that WattTime and Electricity Maps have a relationship with the GSF. Are there any other key differences between the data that is provided? Am I missing any other options? Thanks!
