Pepco supplies power to over 788,000 customers in and around Washington, DC. Following several devastating storms, the company committed one billion dollars to ensure their customers continue to receive power during major weather events. With an investment on this scale, Pepco needed to be sure that their investment would result in the desired outage reduction targets. They also needed to understand the extent to which moving thousands of overhead electricity lines underground would reduce power outages during hurricanes and ice and snow storms.
To give Pepco this greater confidence, we developed a process to collect data from multiple data systems, helping measure outage improvement before and after system upgrading initiatives were put in place. This allowed Pepco to confidently predict the success of multiple reliability improvement programmes, including undergrounding. To further explore the benefits of moving power lines underground, we compared data from these different systems to understand how benefits varied under a range of construction scenarios.
Pepco is using our approach to guarantee the success of their investment. This is proving essential as the company complies with regulation and makes the case for rate increases.
