Landmark agreement combines the environmental attributes of up to 35% nuclear power with hourly carbon-free energy matching to help a Virginia data center operate on nearly 100% clean power.


Key takeaways:

1. Time-aligned nuclear attributes of up to 35% of Microsoft’s data center usage complement Microsoft’s new wind and solar.

2. Performance tracked on Constellation’s Azure-based hourly matching platform.

3. Corresponding timestamped, sub-MWh EACs retired in PJM GATS.


Next steps:

1. Scale the product to other interested customers.

2. Support the development of hourly CFE matching in other regions.
