In response to the issue that electric power enterprises adopt the traditional procurement model for material procurement

overly focusing on the purchase price while paying insufficient attention to the total cost of ownership of materials.Based on the total cost of ownership(TCO) theory

firstly

it constructs a TCO model of power materials covering six stages: planning and design

procurement and business

warehousing and logistics

engineering construction

operation and maintenance

and decommissioning and disposal.Secondly

taking the 10 kV transformer as a typical object

it carries out the identification and quantitative analysis of the total ownership cost of materials

and clarify the cost composition and key control points at each stage.Finally

it proposes to strengthen quality and cost control

implement the TCO theory in phases

and adopts differentiated procurement strategies for different types of materials

to promote the practical application of the TCO theory in material procurement and help electric power enterprises reduce costs and increase efficiency.
