Elk River Municipal Utilities (ERMU) has received its electricity supply from the Minnesota Municipal Power Agency (MMPA) as a member since 2018. ERMU benefits from a diverse mix of energy sources, including wind, solar, biomass, and hydroelectric power. MMPA’s portfolio of renewable resources supports meeting the Minnesota Renewable Energy Standard (RES) and customer demand for renewable energy. The RES requires 25% of MMPA’s energy to come from renewable sources by 2025. Let’s take a closer look! Wind MMPA’s renewable energy portfolio includes wind energy from the Agency’s 44 MW Oak Glen Wind Farm , as well as power output from the 78 MW Black Oak Getty Wind Farm and the 110 MW Walleye Wind Energy Center . In addition, the Agency’s Hometown WindPower program locates wind turbines in our member communities, as well as at MMPA’s Faribault Energy Park. Elk River’s Hometown WindPower turbines can be found at the Plants & Things Recreation Complex. Wind power is one of the fastest growing energy sources worldwide, and it produces no carbon emissions or pollution. Biomass In 2013, MMPA built its 8MW Hometown BioEnergy (HTBE) facility located in the member community of Le Sueur. The facility utilizes anaerobic digestion technology to produce biogas from agricultural and food processing wastes. As one of the largest facilities of its kind in the U.S., HTBE produces dispatchable, renewable electricity, heat, and nutrient-rich byproducts. Solar In 2017, MMPA added the Buffalo Solar facility to its power supply portfolio. The 7 MW utility-scale solar project, located near the Agency’s member community of Buffalo, is comprised of more than 25,000 solar panels. The Agency purchases all of the output of the facility under a long-term contract. In addition, the Agency’s Hometown Solar program locates solar installations in our member communities, as well as at MMPA’s Faribault Energy Park. Elk River’s Hometown Solar array can be found at Elk River City Hall. Hydroelectric Two of MMPA’s member communities, East Grand Forks and Olivia , purchase a portion of their power from the Western Area Power Administration . Because it produces no waste and causes no carbon emissions, hydroelectric power is a sustainable form of energy. HOW POWER GETS TO YOUR HOME

Elk River Municipal Utilities (ERMU) strives to provide quality and cost-effective utility services to its customers. As a part of that mission, ERMU routinely tests for per- and polyfluoroalkyl substances (PFAS). ERMU has conducted PFAS testing in cooperation with the Minnesota Department of Health (MDH) in 2021 and 2025. We are pleased to report that all results showed no detection above MDH guidance levels. Monitoring and Testing Proactive testing protects the health of public water system customers and is the first step to reducing risk from PFAS exposure. As part of its mission, ERMU upholds standards with routine testing of our water quality to ensure services reflect the excellence, dependability, and expertise on which our customers rely. The Minnesota Department of Health has been investigating the impacts of PFAS on groundwater since 2002 and conducts tests of community water systems. In 2021, the MDH began its Statewide PFAS Monitoring Project to evaluate whether PFAS levels across the state exceeded health guidelines. ERMU volunteered to participate in MDH’s 2021 PFAS testing. All sample results showed no detection above MDH guidance levels. In 2025, the MDH conducted another round of statewide PFAS sampling. Once again, all ERMU sample results showed no detection above guidance levels. According to the Minnesota Department of Health, a person who drinks water that is at or below the guidance levels would experience little or no risk for health effects. ERMU will continue to work with MDH to monitor and report PFAS levels in the system as we remain committed to the health and safety of our community.
