Priority to Asset Management

Time to focus on planning contingencies and balancing risk

BY DON ANGELL AND MARK RIVERS, Doble Engineering Company

By definition for electric utilities, asset management refers to an established system used to monitor and maintain valuable commodities such as transformers and power lines. Utilities use asset management to cost effectively deploy, operate, maintain, upgrade, and dispose of critical assets as well as plan for contingencies, and address risk in a balanced and demonstrable manner. However,...
