The City of Sierra Vista is soliciting proposals from Energy Services Companies (ESCOs) to provide energy service and improvements on the existing Wastewater infrastructure, primarily housed at the City's Environmental Operations Park, located at 7201 State Route 90, Sierra Vista, AZ 85635 and other improvements at the plant that can generate energy and other cost savings. For the purpose of this RFP, “ESCO” refers to any entity that is qualified to provide a turn-key utility conservation program that includes the services and requirements set forth in this RFP. The District intends to select an ESCO to perform an energy efficiency project as allowed under Arizona Revised Statutes 34-105. This RFP will be the basis of the City’s selection of an ESCO partner to take the project from preliminary feasibility study to project development, design, construction, commissioning, and performance guarantee.
