Energy Time Shift (ETS) Module

Energy Time Shift (ETS) 20' Module

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.

Benefits & Features

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.
