How to Become an Eligible ESPC ENABLE ESCO

The ESCO is required to complete a two-step qualification process to become an eligible ESPC ENABLE service provider. The process includes:

  1. Becoming a DOE-qualified ESCO
  2. Being awarded a contract under the GSA schedule.

The Federal Energy Management Program (FEMP) maintains a qualifications process for ESCOs that are interested in offering ESPC services. Any ESCO on the GSA Supply Schedule SIN 334512 is required to be DOE qualified before being issued a GSA Schedule award.

Once it is determined that an ESCO meets the DOE qualification criteria, it can begin preparing an offer to be awarded a GSA Schedule contract. GSA Supply Schedule SIN 334512 requires potential vendors to review all solicitation-related documents and submit all items required in those documents.
