Energy Vault AI Power Plant Controller
Always-on power for loads that move in milliseconds.
AI workloads swing a campus load faster than any generator can follow. The Energy Vault AI PPC orchestrates PV, gas generation, grid-forming BESS, and the grid connection as one system, with seamless failover built in, on a fault-tolerant controls platform, so the data center never notices. It de-risks even the largest frontier AI lab deployments.
- 4 yrs of proven BESS and microgrid deployments, US, Europe and Australia
- GW /GWh+ site scale, responding in real time to grid conditions
- ms -class load swings absorbed by grid-forming BESS, generation stays steady
- Frontier scale software that de-risks the largest deployments, with failover the load never notices
Live dispatch
Fast assets take the swings. Slow assets run steady.
Every asset behind the meter sits on a setpoint the controller holds. The grid-forming BESS absorbs each fast swing in the load while the gensets stay flat at their most efficient operating point, so generation runs at peak efficiency with the lowest fuel burn and carbon footprint per MWh.

Illustrative simulation, not site data. Grid interchange stays on its scheduled setpoint throughout. Sign convention: BESS is positive when discharging and grid is positive when importing, so at every sample load = PV + gas gen + BESS + grid.
Orchestration
One controller. Every asset.
One grid connection, or many.
The AI PPC provides overarching power plant controls orchestration across every technology behind the meter, at single or multiple grid connections. Fast assets take the swings, slow assets run steady at peak efficiency, and failover is seamless. Step through five illustrative dispatch moments to see how it keeps a campus energized.

Flow speed tracks power; dashes run toward the bus when an asset supplies it. Values are illustrative.
Scenario 1 of 5 · illustrative
Every asset on its setpoint.
PV carries what the sun gives, the gensets hold a flat setpoint at their most efficient operating point, and grid interchange sits on its scheduled import. The grid-forming BESS regulates around zero at partial state of charge, ready for the next swing.

Real-time at the site. Control from anywhere.
The AI PPC is a technology-agnostic controls suite for real-time monitoring, operational control, and optimized dispatch across every asset behind the meter. It runs as two layers that work as one.
Layer 1 · on site
Real-time power plant controller
Deployed on-premises, it closes the loop on every asset at the site and is designed to keep operating regardless of internet connectivity, so dispatch never depends on a link back to the cloud. It runs as a high-availability cluster, so the controls layer has no single point of failure.
On-site HA clusterNo cloud dependencyHardware agnosticDigital twin
Layer 2 · cloud
Cloud operations and advanced monitoring
Centralized monitoring and control from your operations center and from Energy Vault's remote monitoring facility, with the same operator HMI on site and in the cloud. Advanced monitoring reaches into the data center: every device and every point is monitored and kept available through the lifetime of the asset, for advanced analytics and asset management.
