Municipal Lighting
| 1990-1992 | Streetlights | Partnered with National Grid to replace all existing incandescent and mercury streetlights with improved efficiency high pressure sodium lamps. |
| 1997-2014 | Traffic Lights | The Worcester’s 1,400 red traffic lights were converted from inefficient incandescent bulbs to high efficiency, long-life LEDs (light emitting diodes) in 1997. Since then, most associated green and amber traffic lights have been replaced with LEDs as well. |
| 2007 | High Efficiency Lighting Retrofits | The City completed fluorescent and metal halide lighting retrofit of select City-owned buildings and four public parking garages through a National Grid incentive program. |
| 2013-2017 | Energy Savings Performance Contract (ESPC) Amendments |
The ESPC project scope of work was increased to include nine solar installation projects, and retrofit (conversion to LED) of municipal street lights and the lights in four municipal parking garages raising the total investment to $80 million. As a result, the guaranteed savings to the City have increased to $1.7 million per year for 20 years. |
