Asset management

Western Area Power Administration is continuing to evolve its asset management activities under the Transmission Asset Management Program, called TAM for short, to develop a more mature, data-driven asset planning and investment program.

WAPA’s TAM Program tracks, calculates and analyzes the risks to its core fleet of key equipment assets system wide. Built on the AMPIP, this program was formally established in 2015.

Staffed by employees throughout WAPA’s service territory, the TAM Program’s objectives are to:

  • Integrate asset management principles, practices and policies into Western’s day-to-day business practices.

  • Produce reports that asses the risk, health and criticality critical Western assets — initially transmission lines, circuit breakers and power transformers.

  • Provide trending analysis on equipment assets to inform maintenance planning and assist with 10-year capital funding development.

  • Develop a Strategic Asset Management Plan for future planning, to guide long-term activities.

WAPA uses the data-driven risk-based analysis to inform capital investment recommendations for management, customers and other stakeholders. 

Moving forward the TAM Program will continue IT development and implementation of asset condition metrics for the transmission line structures and conductors; populate inspection data into the transmission line condition database; evaluate additional asset classes for tracking; refine asset condition and risk determination methodologies, and initiate asset life cycle management processes.

Improvement project served as TAM Program roots

Under the original Asset Management Program Improvement Project, WAPA began in 2012 to formalize and standardize how WAPA collects and processes asset data for critical transmission assets across the agency, including how employees evaluate and document asset condition, calculate probability of failure, and determine the consequences of the asset being out of service. Starting in 2014, the project resulted in Western staff creating equipment asset condition reports and providing annual risk-based data-driven information to help with capital investment recommendations and 10-year plan development for senior management, customers and other stakeholders.

By using the industry-accepted, International Standard ​Organization Standard (ISO) 55000, 55001 and 55002 – Asset Management as a guide, WAPA has developed policies, guidelines, business procedures and rules to make asset management a sustainable and repeatable endeavor that will continue to provide quality data for asset optimization. The improvement project focused on processes and procedures for three high value, critical assets—transmission lines, circuit breakers and power transformers.  

The first year’s equipment asset risk reports resulting from the AMPIP effort revealed that WAPA’s most critical equipment asset classes as a whole are in relatively good condition.  In the second year Western developed a risk estimator tool that can calculate future asset class fleet risk, perform what-if analysis, and can be used to optimize replacement strategies for the aging equipment fleet. 

In 2015 WAPA established a Transmission Asset Planning and Management office to continue efforts initiated under the AMPIP project.
