The switch to LED streetlights in the Ameren Illinois service territory continued. Work in Wood River begins today (Tuesday) with a plan to replace about 300 lights. Similar projects are being done around the region, including in Alton, Edwardsville, and Granite City.

The LED lights use 55-65% less energy than older technology, reduces maintenance and operational costs, and has a life expectancy of up to three times the older technology. Utility spokesman Brian Bretsch tells The Big Z the program started small.

Replacing the lights includes wiring a new fixture into place. In all, Ameren Illinois is replacing about 1,900 of the old sodium vapor, mercury vapor, and metal halide streetlights.
