Navistar, Inc. (NYSE: NAV) subsidiary IC Bus of Oklahoma’s Tulsa bus plant will receive a check for $142,498.92 from Public Service Company of Oklahoma (PSO) for retrofitting the company’s Tulsa facility with high-efficiency lighting.

IC Bus invested more than $420,000 for lighting retrofits that included the replacement of more than 1,000 metal halide fixtures (ranging from 250 to 1,000 watts) with the same number of new, high-efficiency T-5 fixtures.

It’s estimated the new energy efficient lighting at the IC Bus plant will save more than 1.5 million kilowatt-hours (kWh) of electricity per year and will lower the facility’s electric bill by approximately $75,000 a year.

The lighting installation qualifies for the incentive payment under PSO’s Business Solutions program, which helps owners of commercial and industrial facilities conserve energy and save money by identifying and implementing high-value energy efficiency improvement projects. Incentives are paid for qualifying projects based on the calculated energy savings resulting from the improvements.

"We are always looking for ways to improve our business and operations at the plant," said Greg Hutchison, manager of IC Bus’ Tulsa plant. "PSO’s Solutions Program, combined with the ongoing cost savings, validates our investment in energy efficiency and helps us maintain a competitive edge."

PSO Consumer Programs Coordinator Kerry Rowland said that the Business Solutions program has proven to be a valuable tool in helping PSO-served businesses reduce electrical demand and hold down costs.

"We identified a real need for an energy efficiency program that specifically targets business facilities, especially as budgets are spread thin," said Rowland. "By partnering with IC Bus to reduce energy costs, their valuable resources can be used for other needs."
