Success Story

Innovative application of proven technologies has been a hallmark of Ever-Green Energy and its affiliates for 25 years.



Innovative application of proven technologies has been a hallmark of Ever-Green Energy and its affiliates for 25 years. It has led to the creation of highly efficient, reliable and economical energy systems that successfully use renewable energy to meet the energy needs of their customers.

Chilled Water Storage System

With electric rates on the rise across the nation, it makes sense to conserve energy and to run appliances and air conditioners during off-peak hours. Downtown Saint Paul businesses keep their employees cool during peak hours but still enjoy the benefits of lower electric rates thanks to chilled water storage.

A chilled water storage system cools water at night using off-peak electricity and then stores the water in a huge tank. The water is distributed to customers during the day at a reduced cost. Ever-Green Energy operates two chilled water storage tanks in downtown Saint Paul. One holds 2.5 million gallons of chilled water and the other holds 4 million gallons.

Chilled water storage
• reduces regional peak electric demands
• improves air quality
• provides greater rate stability
• increases cooling capacity
• provides high overall system reliability
