Demand Shield - Our Energy Storage system for Cold Storage

Stop Paying PG&E Demand Charges for electricity you didn't use.

Stop Paying PG&E Demand Charges for electricity you didn't use.

PG&E bills your facility for a single 15-minute peak - every month. Demand Shield levelizes and significantly reduces that exposure with safe modular battery energy storage systems (BESS) and precision solar built around your demand load profile.

The 15-Minute Problem

Your entire month's demand charge is decided in a single 15-minute window.

One compressor startup, one defrost cycle — and that number sets your demand charge for the entire month, regardless of how well you managed every other minute. Our goal is to shield you from those expensive demand spikes with safe sub zero battery technology installed near demand loads, saving you hundreds of thousands of dollars annually.
