Carrying Obsolete or Incorrect Turbine Spare Parts

$100,000–$300,000 per municipal portfolio locked in obsolete or incorrect spares across sites, with additional $10,000–$40,000 per year in write-offs, storage, and avoidable rush orders when compliant spares are missing. • $100,000–$500,000 per plant in sunk capital plus disposal costs • $150,000–$500,000 per large plant tied up in obsolete or incorrect turbine spare parts over the equipment life, plus $10,000–$50,000 in write-offs, scrapping costs, and premium freight or lost-generation costs when the correct parts are missing.

Inventory controller and maintenance planners periodically export spare-parts lists from ERP/CMMS and manually compare them to PDF/Excel RSPLs from OEMs, marking mismatches on spreadsheets and printouts, or relying on technician memory about which parts ‘no longer fit’ specific turbines. • Inventory controllers compile ad hoc Excel lists for auditors and budget reviews, manually tagging suspected obsolete items by cross-referencing old PO histories, OEM manuals, and technician comments, while the official asset/inventory systems remain unchanged. • Manual reconciliation using spreadsheets to compare RSPL against physical inventory counts
