Download Project Summary
Since 1997, Ever-Green has served as the system operation, maintenance, and management team for EPUC. Ever-Green is responsible for maintaining the highest possible level of reliability to the EPUC customer base, which includes mission-critical data centers and also manages customer service, metering, billing, capital planning, and maintenance for the system.
In 2014, our team also led the conversion of the two-pipe distribution system to a four-pipe system to better serve the heating and cooling needs of the customer base. Throughout that project, Ever-Green led the development of financing packages, extension of customer contracts, pre-construction engineering, distribution system design, construction oversight, and implementation of various plant and customer building improvements for enhanced efficiency.
