Bear Swamp Pump Storage Power Station Automation Project

Plant Location:

Brookfield Power New England
100 International Drive Ste 350
Portsmouth, NH  03801

Project Description:
The scope of participation for L&S Electric included the turnkey supply of a new plant automation system, new unit automation systems and new digital governor control systems for two 360MW Francis pumped-storage units.  Also included were program modifications to the Harris RTU and the upgrade of the existing Cimplicity HMI system.

L&S Electric dispatched a significant number of our own people to site to support the installation efforts in addition to managing contract labor for electrical and mechanical disciplines.  This project is significant not only because of the complex design, but also because of the critical reliability requirements.  As a high value installation, $250,000.00 could be lost for a single failure in the pump mode, and $1,000,000.00 could be lost for every 2-3 days of lost generation.  Therefore, detailed project management and scheduling efforts were required to ensure a timely completion.

As such, L&S Electric worked cooperatively with the customer to address unit scheduling conflicts, and the contract value grew as a result of design enhancements and additional requirements associated with managing an aggressive schedule.
