PSC M1MZ

Overview

The Product Service Code (PSC) system is a government-wide taxonomy used to classify products and services acquired through federal procurement. PSCs are applied in reporting systems such as the Federal Procurement Data System (FPDS) and are maintained via the PSC Manual to support consistent tracking, analysis, and reporting of federal spending. ¹

The PSC label M1MZ — Operation Of EPG Facilities - Other, Including Transmission — is an active PSC used to identify contract actions that primarily fund operation services for energy-producing or power-related facilities that do not fall into fuel- or technology-specific operation categories. The PSC Manual lists operation-of-EPG facility codes and documents prior renumbering of older M-series entries; a more granular formal definitional statement for M1MZ beyond the code label is not provided in the Manual, and the Manual is the governing authority for activation/renumbering records. ¹

What this PSC covers

• Transmission and other non-fuel-specific EPG facility operations
• Substation and switchyard operations
• System monitoring, control-room dispatch, and telemetry support
• Emergency outage coordination and on-site operational response
• Routine daily operation of non-building EPG infrastructure
• Operational support services for facility instrumentation and metering

Not specified by official sources for a more detailed textual definition beyond the label and Manual listings. ¹

Related NAICS and PSC codes

No mandatory NAICS-to-PSC crosswalk is published in the PSC Manual for this specific code; agencies commonly pair facility-operation PSCs with power and utility NAICS codes on a case-by-case basis per program documentation. Not specified by official sources. ¹

Code renumbering and past identifiers

The PSC Manual documents a renumbering and reorganization of several M-series codes (for example, older entries such as M239 were replaced under a new numbering scheme). Historical mappings and activation/end dates are recorded in the Manual appendices. ¹

How agencies report this PSC in FPDS

Agencies must report a single predominant PSC for each contract action in FPDS (data element 8A). When a contract action covers multiple products or services, the PSC selected should represent the predominant line of effort or the item/service that constitutes the majority of the contract value; FPDS guidance and the FPDS data dictionary clarify reporting expectations for PSC selection. ²

Frequently asked questions

• What does the acronym EPG mean in PSC labels?

  • The PSC Manual uses the EPG label within multiple PSC names for energy/power-related facility categories; the Manual does not provide a single-line formal expansion of the acronym. Not specified by official sources. ¹

• How should contracting officers choose M1MZ versus a fuel- or technology-specific operation code?

  • Select the PSC that best represents the predominant service being procured; use M1MZ for operation services not covered by fuel- or technology-specific M-series operation codes. FPDS instructions require selection of the code representing most of the contract value. ²

• Do construction, maintenance, or repair actions use M1MZ?

  • Construction actions are reported with Y-series PSCs, maintenance with Z-series PSCs, and operation with M-series PSCs; therefore construction or repair work should generally not be reported under M1MZ. The PSC Manual and FPDS element rules describe these distinctions. ¹

• Are there standard NAICS pairings for M1MZ?

  • The PSC Manual does not publish a mandatory NAICS-to-PSC crosswalk for this code; agencies typically select NAICS codes consistent with the service delivered and program requirements on a case-by-case basis. Not specified by official sources. ¹
