A replacement strategy for air compressors and blowers integrated into a system-level approach towards energy efficiency can deliver significant energy savings and optimize equipment performance. At the Victor Valley Wastewater Reclamation Authority, a blower replacement project yielded annual energy savings of more than 928,000 kWh and \$98,000 in energy costs, while improving the reliability of its secondary treatment process. In addition, the agency qualified for important incentives from its electric utility — significantly improving the project economics and resulting in a 2.94-year payback.
Since 2002, Energy Trust of Oregon has saved and generated 728 average megawatts of electricity and 52 million annual therms of natural gas. This is enough energy to power Multnomah and Washington counties while heating Deschutes County homes. ETO has saved enough energy equal to the output of a power plant and reduced reliance on fossil fuels. In total, they have invested \$1.5 billion to save customers more than \$6.9 billion on their energy bills over time. They have also added \$5.7 billion to the local economy, including \$1.7 billion in wages, \$312 million in small business income and employment equal to 4,700 full-time jobs lasting a decade.
Compressed Air Best Practices® Magazine interviewed Keith Martin (Director Energy Efficiency) and Cheryl Miller (Energy Efficiency Advisor) from Ameren Illinois and Robert Baumgartner (Business Program Manager) from Leidos Engineering.
Seven years ago, a team of three of us at Ameren Illinois made the commitment to create and deliver a program that would make a difference. Today, the Ameren Illinois ActOnEnergy program is an award-winning energy efficiency program covering southern and central Illinois. After six program years, we are thrilled to report our business customers are saving over \$132 million in annual energy costs due to energy efficiency measures they implemented with financial incentive assistance from ActOnEnergy.
