PSC Y1MH

Overview

The Product Service Code (PSC) system is the federal taxonomy used to classify what is procured in U.S. government acquisitions. PSCs populate FPDS data fields, support spend analysis and category management, and provide a standardized way to report the predominant product or service on contract actions; the PSC Manual on acquisition.gov defines and maintains authorized codes and usage rules.¹

Y1MH is the PSC entry for "Construction of EPG Facilities - Wind." In FPDS reporting the PSC identifies the predominant product/service purchased on a contract action (data element 8A); for construction acquisitions of wind energy production or associated wind-farm facilities the PSC Manual lists this code within the Y1 Construction category.¹

FPDS reporting notes

• PSC selection: FPDS element 8A requires the Product or Service Code that best identifies the item or service procured; enter the PSC representing the preponderant contract value when multiple PSCs apply.²

Maintenance vs. construction distinction

• Ongoing operation, maintenance, repair, or alteration of wind-generation facilities should use the corresponding Z-category maintenance or repair PSCs (for example, Z1MH or Z2MH) rather than the Y1MH construction code.¹

Frequently asked questions

• Q: What specifically does Y1MH cover?
  A: It designates construction actions for wind energy production facilities and associated site work when construction is the predominant contract activity. The PSC Manual lists it within the Y1 Construction category and provides guidance on appropriate use for FPDS reporting.¹

• Q: Where is the PSC recorded in federal award data?
  A: The PSC is recorded in FPDS as data element 8A, "Product or Service Code." FPDS uses codes from the PSC Manual and requires the PSC that most closely represents the preponderant work or supply on the award.²

• Q: Can the same contract use Y1MH for turbine installation and later for ongoing maintenance?
  A: No. Construction (installation and site build-out) is reported under Y1MH; subsequent maintenance or repair work after turnover should be reported under the applicable Z-category maintenance/repair PSCs.¹

• Q: Is Y1MH the same as a NAICS code?
  A: No. PSCs classify the product or service procured (what was bought) for FPDS reporting; NAICS classifies the industry of the performing entity. FPDS collects both PSC (element 8A) and NAICS (element 8G) as distinct data elements.²
