July 2024 Emissions Model

Grid mix updates that increase our emissions model coverage, granularity, and accuracy. Hourly measurement now available!

Grid Mix Improvements

As of July 1, we offer hourly measurement in addition to daily. Grid intensity can fluctuate significantly on an hourly basis due to the variable nature of both renewable energy sources (sun, wind) and electricity demand. To achieve effective decarbonization, having hourly data is critical.

We have real-time data available for an additional 11 countries, 39 countries total. Where real-time data is unavailable, we use published averages or world-wide defaults. On average, this update increases carbon intensity by six percent. However, some regions, like Brazil and India, were more heavily impacted. Check out the changes at scope3.com.

Changes

Carbon intensity data enhancements added as part of the migration from WattTime v2 to v3.

• Hourly measurement now available for supported countries (with a five-hour delay). For example, at June 28 05:00:00, we will build an hourly number for hour 1 which leverages the data points from June 28 01:00:00 - June 02:00:00. This process typically takes ~1 hour, so by June 28 06:00:00 we can begin accepting requests for June 28 01:00:00.
• Real-time data added for 11 countries: Mexico, South Korea, Brazil, India, Chile, Peru, Turkey, Malaysia, Nicaragua, Philippines, and Singapore
• Leveraging improved datasets and emissions factors
