Does Constellation Energy Solutions, LLC hold a GSA Schedule?

Yes. GSA eLibrary lists MAS contract GS-21F-0139V with 5 Special Item Numbers (334512, 541690E, ANCILLARY, ANCRA and OLM); the current option period runs to Sep 2, 2029. Federal agencies can place orders against it under FAR subpart 8.4, through GSA Advantage or GSA eBuy, instead of running a separate open-market buy.

How do I find Constellation Energy Solutions, LLC's UEI or CAGE code?

Constellation Energy Solutions, LLC's UEI on its federal awards is XVPREJLB2MY6. Award records do not carry CAGE codes; search the UEI in SAM.gov's entity search to see the CAGE code and registration status.

Vendor totals add up the award records RFPFinder holds: federal contract awards from USAspending.gov for the agencies and codes behind open notices, and state and local awards from open-data contract registers and purchase-order files. They are not a vendor's complete government revenue, and a register that lists a contract ceiling or repeats a contract can overstate spend. Names are grouped across spellings ("Corp" and "Corporation"); each award links to its source record. Subcontracts are prime contractors' subaward reports on USAspending.gov for the prime awards behind the same agencies and codes, and GSA Schedule contracts come from GSA eLibrary's MAS contractor list; both are matched to vendors by name.
