South Bend LED Traffic <br />Signal Project Economics <br />We have 227 signals that have incandescent bulbs and cost us <br />$159 per month for power each....$440,000 per year for energy. <br />Over the 10 year life of an LED lighting approach we would <br />replace incandescent bulbs 10 times and pay $ 4.4 million for <br />traffic signal power. <br />If we convert to LED, we reduce the energy by 85 % saving <br />almost $ 3.75 million over the ten years....reducing our signal <br />power bill to about $ 660,000. The city will invite a substantial list <br />of energy savings contractors to submit proposals to undertake <br />the conversion project with private lease capital repaid out of the <br />energy savings. The payback out of energy savings will be less <br />than 10 years and then the lease will be paid off and the ongoing <br />savings will belong to South Bend. <br />It's guaranteed....if the energy savings fall short of the guaranteed <br />contract the contractor writes a check for the difference---not <br />South Bend taxpayers. <br />Improved traffic safety, energy savings and environmental <br />benefits, saving taxpayers money, and allowing us to practice <br />effective and efficient local government services. A clear <br />economic winner for South Bend. <br />We acknowledge the help of the Notre Dame professor and class <br />who studied this concept and have been strong technical and <br />public policy advocates for South Bend undertaking this project. <br />~. <br />~~~,- <br />r~=f„ ~`.:.~zs <br />~~._~ <br />,, <br />~- ~.~. <br />1~~~~ <br />Fi1~d In Cl~rk'S OfitiCe <br />F E B 7 2007 <br />ao;~aa vo~~oE ... <br />CITY C~ Er~l~, S0.
