MATERIAL MANAGEMENT

Spares are inevitable for a smooth running of any system.

Stores and inventory play a major & significant role in economical operation of any organization.

Proper storage and transaction of materials result in providing better services and in optimising material resources.

Different procedures and practices are being followed by different organisations for stores management.

For ease of operation and better exchange of information it is imperative to have uniform procedures within different stores of an organization.

material management2
MATERIAL MANAGEMENT
  • POWERGRID has standardised procedures for stores management of all its stores in the form of the documents

“STORE’S STANDARDISED PROCEDURES AND FORMATS” VOL-I & VOL-II

  • The Vol-I covers the standard procedures and formats for receipt and issue of materials, updating material status, disposal of surplus and scrap and stock verification
  • The Vol-II covers broad procedures, policies and guidelines for storage, preservation, material handling and safety and security of materials.
material management3
MATERIAL MANAGEMENT
  • These procedures shall however not be applicable for “construction stores” in the custody of contractors engaged by POWERGRID for various jobs.
  • RESPONSIBILITY FOR IMPLEMENTATION
  • Concerned group head/store in charges
  • Overall responsibility : Regional head.
  • REVIEW

These documents shall be reviewed and updated every 3years.

material management4
MATERIAL MANAGEMENT
  • BASIC TERMS IN MATERIAL MANAGEMENT
  • Materials :
  • All goods including equipments and spares as required for construction (other than under custody of contractors) and O&M of transmission system
  • Personal safety implements, administrative items viz. furniture, furnishings, office equipments and goods as required for township maintenance.
  • Consumables including stationery etc.
  • Scrap

2) Maximum stock level

It is the level beyond which it shall not be desirable to hold the stock. It is decided keeping in view the overall investment, storage space limitations, inventory carrying cost etc. Inventory stock holding norms for maximum level for different category of stores has been defined in the Corp MM circular No. 16 dtd. 4.4.96. The inventory for O&M spares instore shall be maintained as per norms fixed from time to time by Corp. OS/RHQ OS. Norms for administrative items shall be decided by HOD (HR).

3)Minimum Level (Stock)

It is the level below which the stock in hand shall not be allowed to fall so as to ensure the availability of materials for meeting effectively the service requirements

4) Common Pool Material”

Stockofmaterials, (except personal/ administrative /civil maintenance items) available beyondstock holding norms i.e. as per Corp.MMcircular no.16 dt.4.4.06 and/or equipments/ spares available beyond OS norms, shall be deemed to be as surplus material under “Common Pool”.It shall exclude quantum of materials to be issued for “Work in Progress” (WIP)/ Construction.

5) Re-Order Level

It is the level for any item at which action for the procurement of material shall be initiated. Re-order level/quantity of any item is based on procurement lead time, consumption rate as well as uncertainties in usage of items which may differ from substation to substation. However,re-order level for periodical consumable O&M items such as SF6 gas/transformer oil etc. shall be followed as per norms fixed by CC( OS)/RHQ (OS) from time to time. Re-order level for other inventory items, if possible, can be fixed by individual Store-In charge in consultationwith O&M-In charge of Substation/Transmission Line/RHQ (OS) so to keep the inventory available all the time to meet any eventuality.

6) Lead time (LT)

It is the time required to procure material i.e the time lag between the receipt of indent and the physical receipt of material in store. This shall be fixed by the store in charge based on passed experience.

Lead Time = Administrative LT + Supplier’s LT +

Transportation LT

7) Safety stock

This is the quantity of material to be added to the ROL for covering the uncertainties in :

a) Estimation of lead time b) Estimation of lead time usage

Safety stock shall be fixed for each material or a group of material based on past experience and proper analysis

9) Mandatory Spares

  • These are the spares of sub station equipments/capital spares i.e equipment & unit assemblies which are identified for minimum 2-5 years ( or as per contractor operational requirement.) These spares may be required in the event of unforeseen breakdown or accident at any time during the designated life of the equipment whose non availability may affect the working of the entire “Transmission System”.These spares are ordered along with the main equipment package
  • These spares are capitalized along with main equipments and are considered Zero value items for accounting purposes

MATERIAL MANAGEMENT

10) O&M Spares

  • The spares/equipments/consumables are to be procured during O&M stage for smooth operation of the “Transmission System”. The spares of transmission line items and consumable nature of sub station are treated as inventory after commissioning of line/project.
  • These spares/equipment are consideredNumericalLedger / Price Store Ledger (PSL) items for accounting purposes
