Product & Service Offerings

System Planning

New lines, line additions, line improvements, line relocations, line removals, substations, and substation additions all require extensive planning and budgeting. We can provide a complete service or supplement your work force.

System Analysis

Using the latest software, we can assist you with contingency analysis, reliability studies, and other planning studies.

Business Process Improvement

The identification of issues that obstruct the utility or business unit from meeting its goals is the first step in gaining and maintaining a competitive business advantage. Since 1993 Yanco Associates has performed this work at major T&D utilities.

Design

We can support your staff or take on entire projects. From hardware to plan and profile drawings to structure designs, Yanco Associates can help you complete your projects.

Project Management

With experience on some of the largest T&D projects in the world (lines and substations), we can support you on a single project or establish a Project Management Office to support several projects at the same time.

Construction Management

Yanco Associates can provide the field assets to support a simple line relocation or a major transmission expansion program.

Asset Management

Utilities are quickly finding that transmission assets in the deregulated environment are a challenge to operate effectively and efficiently, but also an opportunity to improve earnings. We provide knowledge and experience starting with asset strategic planning and including the complete asset life cycle management.

Information Technologies

From analysis software to line design software to SCADA/EMS systems, we can assist you in planning, product selection, and system implementation. We understand the combined requirements of transmission operations for asset-centric and operations-centric support systems operating in unison to provide a total operations and maintenance solution
