1. Technology overview

Critical Loop is a Los Angeles-based industrial power company that provides behind-the-meter batteries and controls so industrial sites can obtain power faster. It targets sites that wait years for grid upgrades, including AI data centers and industrial electrification loads.

The Cygnus software-defined controller monitors grid conditions, draws the maximum available utility power and fills gaps with on-site storage and generation. It is paired with modular, relocatable megawatt-scale battery systems, and the company handles development, financing, permitting, deployment and operations.

2. Highlighted features & specifications

  • Cygnus controller: Software-defined controller that coordinates grid power, storage and on-site generation.
  • Real-time grid monitoring: Tracks grid conditions and draws the maximum available utility power.
  • Modular batteries: Megawatt-scale, relocatable battery systems.
  • Standards compliance: UL 3141 and IEEE 2030.5 certification.
  • End-to-end delivery: Development, financing, permitting, deployment and operations handled by the company.

3. Potential application

A data center operator in an industrial park bridges a delayed grid connection with relocatable batteries. A factory with a new production line adds peak shaving and backup. A test facility needs temporary megawatt-scale power.

4. Benefits

Shortens time to power for industrial sites, with the company citing months instead of years. Cygnus is described as dual-certified under UL 3141 and IEEE 2030.5. Relocatable battery units can be moved as grid constraints shift. The company reports 50 MWh deployed and plans 100+ MWh in 2026.

6. Other information

Los Angeles-based per press coverage. Raised a $26M Series A announced April 13, 2026, bringing total raised to $49M, and agreed to source domestic storage from LG Energy Solution Vertech.
