Expected annual savings on fuel costs


In Oklahoma, the State Energy Office leveraged $3.95 million of SEP funding and federal and state tax credits to help Tulsa Public Schools (TPS) convert its entire fleet of 140 diesel-powered buses to compressed natural gas (CNG). Once all buses are converted the school district expects to save between $750,000 and $1 million annually on fuel costs. The cost savings that are generated from this project are going back into upgrading the TPS's fueling infrastructure.
