Duke Energy turns to Burns & McDonnell for transmission system analysis

SUBNET Solutions Inc | Wednesday, April 13, 2011

Officials from Duke Energy recently announced that the company has selected Burns & McDonnell to conduct a survey and analysis of its transmission system to enable NERC compliance.

Duke Energy has more than 12,000 circuit miles of at least 100 kilvolts in its system, which Burns & McDonnell will survey. NERC had issued an alert - the Facility Ratings Methodology Level 2 alert - last October with which all energy companies must comply.

Through the use of aerial surveys of transmission facilities to analyze current conditions, Burns & McDonnell will determine how the company's field operating conditions are affecting its transmission facility ratings. Analysis of the aerial surveys will be conducted through thermal assessments for each line. Burns & McDonnell will then report back to Duke with any areas that are non-compliant.

Currently, all assessments and reporting requirements for high-priority discrepancies are due to NERC by the end of 2011. Medium-priority discrepancies are due by the end of 2012, and low-priority by the end of 2013.

The goal of NERC's alert is to identify the scope of the national problems, prioritize which systems need the most attention and then implement the best maintenance processes possible to ensure reliable operations.
