Overview

The Cat® Energy Time Shift (ETS) module is a scalable, rapidly deployable energy storage system. The energy storage system integrates with the utility, generator sets and renewable sources to store energy for use at a later time. The system may provide temporary backup power to facilities in the event of a power outage.

Reliable and Scalable

Factory prepackaged and tested

Pre-engineered containers shipped as a single unit with batteries, inverter, isolation transformer and other equipment installed.
Parallel ready - Multiple energy storage modules may be operated in parallel to provide increased power output and/or increase the battery kWh capacity from 30 minutes to nine (9) hours of capacity per energy storage system.

Renewable Integration

Designed to work with an array of renewable systems, including solar and wind
Integration with the Cat Microgrid Master Controller (MMC) allows for time-shifting of renewable energy for increased renewable content and full asset control allows smoothing of intermittent renewables.
The grid forming Cat Bi-Directional Power (BDP) inverter allows generator set(s) to be completely switched off, further reducing fuel consumption and operating costs.

Transient Assist

When used with a generator set, the Energy Storage System will provide reserve power capacity to:

Decrease the transient voltage and frequency dips resulting from the application of large loads.
Enables highly-efficient lean-burn gas gensets to operate in island mode.
And enables the shutdown of one or more gensets for fuel savings.

Grid Stabilization

Protects against many typical power problems, including power failure, voltage sags/surges, and under/over frequency conditions.

High Performance Inverter

Built-in controls for the charging and discharging of the energy storage equipment.
Static VAR compensator.
Four-quadrant output power factor control.
Aautomatic anti-islanding to meet UL 1741 and synchronization back to grid.
