Caterpillar Diversifies Power Offering by Expanding the Cat^® Energy Control System (ECS) Portfolio, Enabling Customers to Scale and Evolve Their Energy Solutions.

For Release: June 2025

IRVING, TEXAS—Caterpillar Inc. today announced the launch of two new Cat^® Energy Control System (ECS) solutions, the Cat ECS 300 and Cat ECS 400. These advanced control systems seamlessly integrate with sites using singular or multiple power generation assets such as generator sets, battery energy storage, and renewable energy sources. Designed to deliver reliable power and enhance energy efficiency, these solutions allow customers to optimize their energy management and achieve energy cost savings.

The Cat ECS 300 and Cat ECS 400

The Cat ECS 300 features mains/utility paralleling, allowing customers to monitor and control up to four power generation assets concurrently, with or without the utility. This capability provides customers with the flexibility to use their on-site power generation assets more effectively, such as during high energy consumption hours, delivering energy savings. Additionally, the ECS 300 offers closed transition with soft load/unload or open transition with mains/utility operation for emergency standby, providing reliable backup power in the event of a grid failure.

The Cat ECS 400 is engineered for advanced microgrid solutions, with the capability to monitor and control up to 32 power generation assets. This system not only enables customers to expand their existing sites by managing additional power generation assets but also helps maximize the use of renewable energy sources, leading to reduced fuel consumption and overall lower energy costs.

“As the energy landscape evolves and energy needs become more complex, customers are developing plans to secure power for both the near-term and the future” said Melissa Busen, senior vice president for Caterpillar’s Electric Power Division. “Our Cat ECS portfolio helps customers scale and future-proof their sites, as our control systems can adapt and grow alongside their changing needs.”

Extensive and Integrated Customer Offerings

The expansion of the Cat ECS portfolio underscores Caterpillar’s commitment to delivering a comprehensive, customer-focused offering that encompasses equipment, controls, technology, and local support. This holistic solution includes power generation assets, remote-monitoring technology, distributed energy storage management systems (DERMS), switchgear, controls, and local expertise, all aimed at helping customers secure reliable and affordable power.

Expanding The Existing Cat ECS Range

The new controllers join two existing Cat ECS solutions, the Cat ECS 100 and Cat ECS 200, already on the market. The Cat ECS 100 delivers a valuable control system for new standby, fast-response and prime power generator sets.  

Solutions Available Today

All controllers are now available at Cat dealers worldwide with retrofit kit options for the Cat ECS 100 and Cat ECS 200. Caterpillar also offers services for control customization, including system design and hardware and software configuration, allowing bespoke solutions to be developed for specific site needs.
