Cat Expands the Cat Energy Control System Portfolio
6/14/2025
The new Cat ECS range offers a series of integrated, connected, and scalable controllers that enables customers to flexibly manage their energy needs, from single generators to cohesive full-site microgrid solutions.
Caterpillar 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.”
