Street Lighting and the Networked City

Networked street lighting combines the latest in city-scale, energy efficient lighting and digital networking. Technology used in this type of street lighting includes smart meters and LEDs.

Recently, Osram announced its networked street lighting solution using technology from Echelon, a San Jose-based networked street light company.

The technology would save 40 percent more energy with the city’s street lighting system, compared to just using high-efficiency lamps alone.

“The vast majority of the world’s streetlights remain inefficient. Without a network however, there’s no way to tell whether they’re still working or have broken down. Connecting them to a network can offer real-time control of whatever functionality the light itself offers.”

Networked street lighting makes sense in most cases, especially given all the extra functionality. In fact, “street lighting networks can pay for themselves in energy savings in markets where electricity costs about 15 cents per kilowatt-hour or more.”

LED Street Lighting in Buffalo, NY

LED street lighting

The city of Buffalo recently updated their street lighting to LED, increasing security, safety, and savings for the city.

The streets of Buffalo, New York are a little brighter these days. The city recently updated their street lighting to LED, increasing security, safety, and savings for the city.

During 2011, commercial and institutional buildings, and street and highway lighting, consumed “about 275 billion kilowatt hours for lighting or 21 percent of commercial electricity consumed,” according to the U.S. Energy Information Administration.

Cities are finding out quickly that changing out older streetlights for LED lamps can reduce energy use. Compared to high pressure sodium lamps, LEDs use less energy, and also handle outdoor temperature changes and moisture better. Plus they are more attractive for use as outside security lights, and provide better directional lighting.

“LED streetlights can quickly show a return on investment by offsetting the high up-front expense with lower energy costs, longer life, and reduced maintenance.”

LED Street Lighting to Surpass $2 Billion by 2020

LED streetlight

The market for LED street lighting is expected to generate more than $2 billion in annual revenue.

Falling costs and improvements in efficiency are driving the increased sales of LED street lighting lamps. According to a new report from Pike Research, “LEDs will become the second-leading type of lamp for streets in terms of sales by 2020.”

The costs of LED street lighting have fallen as much as 50 percent over the past two years, and are expected to continue falling. The market for LED lamps is expected to generate more than $2 billion in annual revenue. The current most popular street lighting is high pressure sodium lamps.

“Smart street lighting systems can provide a backbone for other smart city applications, and conversely, a city investing in networking capabilities for smart city applications should also be looking to include better management of street lighting,” says research analyst Jesse Foote.

The Smart Street Lighting report also noted how the adoption of LED street lights is seriously hindered by the ownership models and tariff structures in place across the U.S.

“If utility companies own street lighting systems and charge a fixed tariff per light to municipalities, then towns have little financial incentive to pay for upgrading their lights. However, the potential for significant energy savings, reduced emissions and improved quality of service, combined with falling LED prices, means that more and more cities will find this an attractive proposition over time.”

The report analyzed the global market opportunity for lamp upgrades and lighting controls in five public outdoor light categories: highways, roads, parking lots, city parks, and sports stadiums.

Fayetteville Converts 300 Streetlights to LED

The streets of Fayetteville will be brighter and more efficient by this time next year. As part of a pilot study by the Public Works Commission, the city-owned utility plans to convert 300 streetlights to LED.

Light emitting diode technology lasts three times as long, and uses about half the electricity of sodium-vapor powered lights, the most common type of streetlight. It’s no wonder that large cities are switching their public lighting to LED fixtures to save money and make the streets brighter.

Once retrofitted with LEDs, the streetlights will cast a white light that reduces dark spots that form between poles. Retrofitting to more efficient lighting is an investment, but the lighting and environmental benefits certainly outweigh them.

Cities Are Satisfied with LED Streetlights

A recent survey found that 95 percent of cities that have implemented LED streetlight projects were satisfied with the performance of the lights.

A recent survey found that 95 percent of cities and municipalities in the United States that have implemented LED streetlight projects were satisfied with the overall performance of the streetlights.

Northeast Group, a Washington D.C.-based research firm, surveyed nearly 100 cities and municipalities across the U.S. that have implemented some form of LED streetlight initiatives.

“LED streetlights are transforming cities and municipalities across the U.S.,” said the firm. “LED streetlights [are] helping save money through reducing energy and maintenance costs.”

Surprisingly, most of the cities surveyed had only converted a small percentage of their streetlights to LED. In addition, LED streetlights also turn on and off nearly instantly and have dimming capabilities. The controlled features on the streetlights help further reduce energy consumption.
