Energy Cost Reductions in City Buildings

Saint Paul continues to invest millions of dollars in energy-efficiency projects using an American Recovery and Reinvestment Act (ARRA) grant received from the U.S. Department of Energy in 2009. The $2,767,000 Energy Efficiency and Conservation Block Grant has allowed the city to improve the energy efficiency of municipally-owned facilities, retrofit the city’s streetlights to utilized light emitting diode technology, invest in electric vehicle charging stations, invest in the Saint Paul Port Authority’s Trillion BTU Program, provide homeowners loans to conduct energy audits and make energy efficiency improvements, and provide sub-grants to the non-profit Neighborhood Energy Connection to assist residents in reducing energy usage and greenhouse gas emissions.

Many lighting retrofit projects and energy management system installations occurred in the last two years, and the city is continuing to promote energy efficiency projects. Energy Efficiency Projects in City-owned Buildings:
