Solution
Beaches Energy Services selected Burns & McDonnell on the basis of its extensive experience in the state, in electrical transmission and distribution projects, and in successful EPC project delivery.
We supported the installation and energization of Autotransformer No. 2, including removal and replacement of the existing equipment. The station is now able to provide more capacity to the system, as the rating of the transformer increased.

Solution
Beaches Energy Services selected Burns & McDonnell on the basis of its extensive experience in the state, in electrical transmission and distribution projects, and in successful EPC project delivery.
We supported the installation and energization of Autotransformer No. 2, including removal and replacement of the existing equipment. The station is now able to provide more capacity to the system, as the rating of the transformer increased.
Our scope also included the addition of a 138-kV station service voltage transformer (SSVT) connected to the 138-kV ring bus, providing a measure of redundancy. We replaced five motor-operated disconnect switches, replaced electromechanical relays with digital relays, and provided all necessary relay panel modifications and upgrades. These improvements provide more reliability to the protection of the system.
Results
The new autotransformer was energized in less than a year, with construction completed in four months, delivering the speed and cost certainty the utility sought.
Since EPC is relatively new to the utility, the open-book process allowed us to share our methods to demonstrate advantages of that integrated delivery approach, including a single source of responsibility and compressed time frames for predictable results.
