PSC X1MC

Overview

The Product Service Code (PSC) system is a government-wide taxonomy used to classify goods and services purchased by federal agencies for procurement, reporting, and analysis. PSC codes populate FPDS/SAM contract records (data element 8A) and are maintained through the PSC Manual and associated change-control procedures to promote consistent federal spend reporting across agencies. The PSC framework supports reporting, spend-analysis, and category management activities by giving a common codebase for products and services tracked in federal procurement systems. ¹

The PSC code X1MC is listed in the PSC Manual as "Lease/Rental of EPG Facilities - Geothermal." It is used to identify contract actions where the predominant acquisition is leasing or rental of geothermal energy production facilities or their space and infrastructure. The PSC Manual provides the code descriptor but does not supply a detailed inclusions/exclusions list for this code. Not specified by official sources. ²

What this PSC covers

• Lease or rental of equipment, structures, or plant space used primarily for geothermal energy production and generation.
• Rental agreements for geothermal site infrastructure required for extraction, conversion, or generation.
• Lease or rental of subsystems dedicated to geothermal extraction and electrical conversion (predominant purpose must be geothermal operations).
• Short-term or long-term occupancy arrangements for geothermal operations and related facility space.
• Related real-property facility leases that are predominantly geothermal in purpose.

Detailed inclusions and exclusions are not defined in the PSC Manual; agencies must select the code that best represents the predominant product or service reported for the contract action. Not specified by official sources. ²

Related NAICS and PSC codes

Type | Code | Descriptor

• | - | - PSC | X1MB | Lease/Rental of EPG Facilities - Gas
  PSC | X1MD | Lease/Rental of EPG Facilities - Hydro
  PSC | Y1MC | Construction of EPG Facilities - Geothermal
  PSC | Z1MC | Maintenance of EPG Facilities - Geothermal

Related PSC mappings are drawn from the PSC Manual code lists; when multiple codes could apply, agencies should record the single PSC that represents the majority of contract value or the predominant procurement outcome. ²

Usage notes

• Select the PSC that reflects the contract’s predominant type of leasing or rental. When contract scope spans leasing, construction, and maintenance, record the PSC representing the majority of contract value or the predominant deliverable. Not specified by official sources. ²
• PSC descriptors are concise by design; procurement offices should use the contract statement of work, program guidance, and the PSC Manual to determine the most appropriate code when scope crosses categories. ²

Frequently asked questions

• Q: What is the authoritative source for PSC definitions and change procedures?
  A: The PSC Manual on Acquisition.gov is the authoritative government-maintained source for PSC definitions, activation and end dates, and change-control procedures. Agencies should consult the manual for official code text and policy. ¹

• Q: If a contract builds a geothermal plant and then leases it, which PSC should be used?
  A: Code the contract to reflect the predominant action. If construction is the majority activity, use the applicable construction PSC such as Y1MC; if leasing of the completed facility is predominant, use X1MC. ²

• Q: Where is the PSC value entered in FPDS?
  A: The PSC is entered in FPDS data element 8A, "Product or Service Code." FPDS help and guidance explain how the field is used for reporting, searching, and analysis. ³

• Q: Does the PSC Manual list detailed inclusions/exclusions for X1MC?
  A: The PSC Manual lists X1MC by descriptor only and does not provide a granular inclusion/exclusion list; agencies must interpret the descriptor relative to the contract’s predominant purpose. ²
