Case Study: Talen Energy achieves faster, lower-cost outages with Prometheus Group’s STO Execution

Susquehanna Nuclear Drastically Reduces Costs and Duration of Outages with STO Execution

Susquehanna Nuclear, a subsidiary of Talen Energy, faced significant challenges in managing its large-scale nuclear refueling outages. The company struggled with inefficient, paper-based scheduling that lacked real-time data, leading to communication silos, time-consuming manual updates, and a high risk of errors. To address these issues, they partnered with vendor Prometheus Group to implement its STO Execution and Maxavera solutions.

By implementing Prometheus Group's web-based solutions, which integrated seamlessly with their Primavera P6 scheduling tool, Susquehanna gained real-time visibility and communication capabilities. This allowed for live schedule updates from the field, eliminated lengthy review meetings, and empowered teams with greater accountability. The results were substantial, including a 13% reduction in outage duration, a one-hour reduction in shift turnover time, a 50% reduction in meetings saving 700 person-hours, and overall improved cost savings and schedule management.
