WINDSOR, Colo. - Ice Energy, a leading provider of ice energy storage systems, has announced a strategic relationship with Trane, a business of Ingersoll Rand, to develop and deliver energy storage-compatible, high-efficiency air conditioning systems for commercial customers.

Under the terms of the agreement, select Trane rooftop models, ranging from 4-20 tons, will be shipped “Ice-Ready” by Trane for seamless integration and optimal performance with Ice Energy’s Ice Bear energy storage systems.

The two companies will also work together to offer new, high-efficiency air conditioning systems to key national accounts and other customers who are building new or seeking to replace or upgrade their existing systems in conjunction with an energy storage installation.

Pairing high-efficiency Trane commercial packaged HVAC systems with Ice Energy’s distributed energy storage technology on small to mid-sized commercial buildings enables a significant change in how and when energy is consumed for air conditioning. According to the companies, the combined solution helps commercial customers reduce on-peak electricity demand, increase energy efficiency, and reduce their building’s environmental footprint.

“Combining Ice Bear energy storage with high-efficiency Trane systems represents an exciting new approach to helping our customers shift their peak electricity demand,” said Tom Troyanek, director, sourced product development for Trane. “They can now take advantage of more efficient nighttime power to provide daytime cooling, which can lower energy costs without impacting occupants’ comfort.”

“We’re pleased to align with Trane to offer a turnkey solution for virtual ‘plug and play’ integration with our products and controls,” said Brian Parsonnet, chief technology officer for Ice Energy. “Companies like Trane are an integral part of the ecosystem we are building to deliver a scalable, reliable, and cost-effective solution to utilities for addressing the problem of peak demand.”

The Ice Bear system stores energy at night by freezing water in an insulated storage tank. During the day it works with the Ice-Ready™ air conditioning systems to dispatch the stored energy to deliver cooling to the building, significantly reducing the amount of electricity required on peak. During off-peak hours, the conventional HVAC system operates as usual.

When aggregated and deployed at scale, Ice Energy said its Ice Bear energy storage system represents a new, sustainable energy solution equivalent to thousands of megawatts of clean peak power for utilities, enabling them to deliver more reliable and affordable electric service to their customers.

Last year, the Southern California Public Power Authority announced plans to undertake a 53-megawatt (MW) energy storage project utilizing Ice Energy technology. The project represents the potential to deploy integrated Ice Bear and Trane systems on thousands of locations throughout Southern California.
