EPRI DCFlex - Data Center Flexibility Initiative (programme site)

Overview

DCFlex is a collaborative programme of EPRI (Electric Power Research Institute) that studies how data centres can flex their load to support grid reliability and faster grid interconnection. The source is a programme site, not a report or standard, so its content is more a presentation of ongoing work.

The programme tests real-time data centre flexibility at nine active demonstration sites. Work runs through five workstreams: Workstream 1 covers grid-informed flexible data centre designs and operating practices, Workstream 3 flexible interconnection practices and study frameworks, and Workstream 5 distribution-connected data centres (DxDCs).

The site also links to a DCFlex Oscillations page on the grid impacts of dynamic data centre loads. This shows that the power-swing and oscillation risks of rapidly varying loads, such as AI training clusters, are being followed within the programme.

The limit is that results are not summarised in the record; only the programme structure and the number of demonstrations are known. IEEE 2800 (analogous) and NERC large-load guidance are named as related. Its value for designers is as a pointer to which parameters to expect in flexible-interconnection studies.

Key points

1. DCFlex tests real-time data centre flexibility at nine active demonstration sites.
2. Workstream 1: grid-informed flexible data centre designs and operating practices.
3. Workstream 3: flexible interconnection practices and study frameworks.
4. Workstream 5: distribution-connected data centres (DxDCs).
5. The site hosts a DCFlex Oscillations page on grid impacts of dynamic data centre loads.
6. The programme comprises five workstreams.

Using it in design

• In the electrical/grid module, let users declare a flexible-load capability (curtailable MW, duration, ride-through via BESS) for interconnection studies.
• Flag AI training clusters for power-swing and oscillation review.
• Use the DxDC workstream as a reference for distribution-connected facilities.
