Jim Donovan, our electrician at the Billerica Water Treatment facility on Treble Cove Road was on site in September of 2008 when the 480/277 three phase Energy Avenger (Watt Warrior) unit was installed.  The unit was installed to treat 40-250 Watt High Pressure Sodium lamps on the quarter mile road that leads into the plan from Treble Cove Road.

The percentage of voltage reduction achieved by the unit has consistently been 20.1%.  Mr. Donavan and the Treatment Plant staff have agreed that there has been no light degradation and in fact the lights have appeared to be brighter.

The unit has performed as expected and the ISI team is continuing to offer the town the opportunity to make use of other energy conservation solutions.  Please contact me if you need any other information.
