Pre-Qualified ESCO Listing

PRE-QUALIFIED ENERGY SERVICE COMPANY LISTING BY STATE AND TERRITORY

Several State Energy Programs have pre-qualified Energy Services Companies (ESCOs) that have been vetted to be eligible to compete for projects with respective state agencies. This allows the State to develop efficient program delivery standards by identifying companies that meet the minimum requirements of the state. This is an important process for state agencies to be able to select appropriate companies. Please bear in mind that this is a partial list, as some states are currently developing or renewing their lists or did not respond to Energy Services Media. The lists shown were copied from the state’s published listing. We will continue to add and update the listing. Other lists that can be used are the NAESCO list of Accredited Energy Services Providers/Energy Services Companies or the U.S. Department of Energy (DOE) list of qualified providers.

While these lists play important roles in each market, it is important to understand that there are many other ESCOs, not on the list, that may be delivering services in that respective market that have strong operational capabilities. For questions, reach out to the State Energy Office or State Energy Program for advice and direction.

Note: Listings were copied from the state’s published pre-qualified ESCO list. – Updated 1/18/23 

ALABAMA

The ESCO’s listed with the DOE are eligible to engage in Energy Savings Performance Contracts, as are others if they meet the state’s project criteria and are in accordance with the Guaranteed Energy Cost Savings Act 41-16-140 / – 143.  The DOE Qualified ESCO list is for reference only and does not exclude anyone from participating if they meet the criteria.
