Over the past century, electric utilities in the United States constructed and expanded their bulk electric system (BES) transmission infrastructures (above 100 kV) to meet enormous load growth demand. Parts of these transmission systems are beginning to exceed expectations, and utility companies are beginning to evaluate their infrastructures to determine what needs to be done to continue to maintain a high level of reliability.
Pepco Holdings Inc. (PHI) determined it needed to assess transmission assets, looking at age, condition, overall reliability and resiliency. PHI completed the system assessment, identifying the scope of potential upgrade projects needed to continue reliable service.
