The city of Las Vegas, Nevada, has started to implement an ambitious plan to update most of the city’s streetlight inventory to energy efficient LED streetlights. Implemented in a two phase process, the city will ultimately install nearly 42,000 LED streetlights resulting in over $2 million in savings for the municipality annually.
“We had been watching LED technology for some time, and once it made sense from a performance and price perspective, we worked on developing specifications for our illumination needs,” said Niel Rohleder, assistant traffic manager for the city of Las Vegas. The deployment will take place in two phases. Phase One targeted 6,600 existing high pressure sodium (HPS) for replacement. Phase Two will replace approximately 36,000 HPS fixtures with LED streetlights.
“Phase One deployed LED streetlights in six areas throughout the city in order to get responses and feedback about the new technology,” said Rohleder. This installation was budgeted at $3.2 million, and was partially funded by an Energy Efficiency and Conservation Block Grant (EECBG), rebates from Nevada Energy, and a qualified energy conservation bond. The GE Evolve LED streetlight was selected during a competitive bidding process.
“Phase Two is currently in progress and we are working from the Northwest of the city to the Southeast,” said Rohleder. The GE Evolve LED fixture is also being used in this installation. “This phase will show more significant savings because we are able to use lower wattage to achieve proper illumination and meet lighting standards,” said Rohleder.
The city is expected to save about $2 million per year in energy cost savings, and about $400,000 in maintenance costs. These savings will result in an aggregate payback of about eight years. All of the city’s streetlights are metered, so accurate calculations of energy savings are expected.
“About 20 percent of our inventory is non-cobrahead streetlights,” said Rohleder. A bid for those replacement fixtures is expected in late 2012 or early 2013.
