Overview

The Cat® PGS Module is a scalable, rapidly deployable energy storage system with a heavy-duty battery structure. The PGS integrates with solar and other renewable sources to provide short duration power when the renewable source is not available or virtual spinning reserve to optimize generator sets efficiency. This system provides transient assist and grid stabilization to the installation.

Reliable, Scalable, and Mobile

The Cat PGS module is a robust, mobile energy storage platform. The module consists of a pre-engineered container that is easily installed on site. Multiple modules may operate in parallel with other power sources to provide increased power output and/or increase the energy capacity.

Renewable Integration

The modules are designed to work with an array of renewable systems, including solar and wind. Seamless integration with the Cat Microgrid Master Controller (MMC) allows for maximum renewable penetration and full asset control.

Grid Stabilization

The Cat PGS protects against many typical power problems, including power failure, voltage sags/surges, and under/over frequency conditions.

Cat® Bi-Directional Power (BDP) Inverters

The Cat BDP inverters are the core to the energy storage system. Based on technology developed for Cat electric drive machines, the Cat BDP provides exceptional reliability, durability, and features that include:

Intelligent controls for the charging and discharging of the energy storage equipment.

Energy Storage

Advanced lithium-ion batteries provide good energy density, high discharge/recharge efficiency, and high cycle life.
Heavy duty battery structure provides vibration isolation during transport.

Applications

Grid firming/grid stabilization
Generator set transient assist
Black Start Capability/ Rig Up Power
Reserve Power Capacity
