Challenge

After decades of underinvestment, San Diego’s street lights were acutely outdated and inefficient. The city (pop. 1.4 million) wanted replacements that maximized performance, energy efficiency, and financial savings.

Solution

It decided to pilot an upgrade of 3,000 street lights, each fitted with a meter connected through a cellular network so, among other features, new LEDs can be dimmed or brightened as needed. The result was a 60% savings on energy bills, or $250,000 a year.

Even more dramatically, the wireless mesh network allows the street lights to gather information and “talk back” to the city: A second pilot deployed 40-50 enhanced sensors (optic, auditory, and environmental) downtown that showed the public all available parking in real time and alerted enforcement to parking violations, thus turning over parking spaces faster.

To engage the public and solicit suggestions about the second pilot, the city held a street light block party downtown that showcased a huge mural (done by a social media artist) which asked citizens: “What do you think an intelligent city can be?” About 300 turned out, many writing on the mural their ideas on ways to use enhanced sensors (eg, providing the safest route to walk to school).

Based on this second pilot, the city is now doing a $30 million upgrade to its street lights (financed by GE Current) in which 14,000 street lights will be converted to LEDs with wireless adaptive controls, and up to 6,000 will have enhanced sensors with 100% deployment in the city’s underserved neighborhoods. Savings: $2.4 million a year on utilities alone.
