CEDAR RAPIDS – Interstate Power and Light Company (IPL), an Alliant Energy company, is expanding its advanced street lighting technology project state-wide by upgrading its streetlights to increase energy-efficiency and performance with light-emitting-diode (LED) fixtures. This improved technology saves energy and improves the lighting quality on roads.
The vast majority of streetlights in Alliant Energy communities across Iowa are high-pressure sodium (HPS). Most of these lights feature a 100-watt bulb. As these lights fail, Alliant Energy will replace the HPS fixture with an 80-watt LED fixture. Alliant Energy owns or maintains around 44,000 of these specific streetlights in its Iowa service territory, and expects the change-out process to take around seven years. IPL already successfully implemented this project pilot in the Cedar Rapids community in the summer of 2012.
“We are excited to bring this new energy-efficient technology to our communities in Iowa. This is a win-win for our customers because this upgrade will increase both the energy-efficiency of the lights and it will enhance the quality of light on the streets,” said Tom Aller, President – IPL.
Initial estimates show switching this specific light, when all are switched, will reduce annual energy usage in the state by almost nine million kilowatt-hours (kWh). For comparison, the average Iowa home used 10,776 kWh a year according to the Energy Information Administration’s latest information – 2011.
The light produced by LED streetlights is directed at the ground better than the HPS. The LED also produces a truer white light, allowing the human eye to see colors and details better.
An Alliant Energy spokesman said Thursday that “we’ve installed two LED lights now in Mason City. More will come.”
The addresses in Mason City are 14th St SE and S Georgia Ave and 20th St SW and S Taft Ave. There is also an LED installed at the 400 block of S. 10th street in Northwood.
Looks like some spyware is also attached – pizza hut buglers beware.
Alliant is a ripoff.
My even pay bill jumped 43+% this month, which was nearly $100. It went down last summer so it isn’t even the anniversary date. They just can’t seem to get it right. I would rather they would have left it higher last June before the hot part of the season than have a huge jump all at once. I hope these energy-efficient lights save our municipalities some money.
