Why smart streetlights are the gateway drug for smart grids (and smart cities)
Quick Take: Smart street lights are suddenly the rage amongst cities around the world. The initial impetus is typically energy savings. By replacing old-fashioned bulbs with LEDs, cities can save 40-70% on their street lighting energy bills. And for many cities, street lights eat up 25% or more of their energy budget.
But the LEDs are far from the full story. As long as cities are sending a truck out anyway, they are also installing other gadgets to take advantage of the fact that street lights a) already have power, b) are pervasive throughout the city and c) are perched on a high vantage. They are installing such things as:
- Communications modules to create a canopy network throughout the city
- Security cameras
- Proximetry sensors that dim the lights when there's no one around
- Software to strobe the lights to lead police and fire to the site of an emergency
Once a city has a canopy network in place, it can then use it for a wide variety of smart grid and smart city applications.
The example below comes from Silver Spring Networks, and there are dozens of other companies offering variations on this theme. I think utilities everywhere should be investigating how to help the cities they serve gain the benefits of smart street lights. â€“ Jesse Berst
