All RPU customers urged to monitor the temperature of their water

Rochester Public Utilities (RPU) is starting to hear from customers that are concerned about their water service freezing this winter. Current frost depth is 32” as of January 25, 2019.

RPU advises these water customers to take the temperature of their water and then continue monitoring it until the frost is out of the ground. This is especially important for customers that have experienced froze water services in the past. Run an inside cold tap and hold a thermometer in the stream for 10-20 seconds for an accurate reading. If your water temperature gets below 35 degrees Fahrenheit, you should immediately start running a continuous pencil-width stream of water from a faucet.

Currently, MN DOT is recording the frost depth at 32 inches in Rochester and Olmsted County. Service lines are typically buried six feet (72”) or more below the ground from the street to the house. Thawing a frozen water service can cost $800- $1,500. The cost to run a constant pencil-width stream of water is approximately $60- $100 per month including sewer fees. If you are going to be letting your water run, please contact RPU at 507.280.1500.

All businesses and residence types could be affected. The age of your home does not matter.

Individuals and Organizations to be recognized for Environmental Achievements in the Community

Rochester Public Utilities (RPU) and the Olmsted County Environmental Commission announce the recipients of the 2018 Environmental Achievement Awards. The recipients will be recognized at an awards banquet tonight, January 17, at the Rochester Golf and Country Club. The awards honor individuals, organizations, schools and businesses that have made a significant contribution in 2018 towards environmental quality in any of the following categories: renewable efforts, conservation, energy, water, agriculture, education, and other.

The 2018 recipients are:

Keith Anderson

The Monarch butterfly is easy to spot with its wings of bright orange, black, and white polka dots. Every fall, these amazing creatures embark on a journey that extends over 2,000 miles, migrating from their home range in Canada and the United States to the forests of Central Mexico. More than just a pretty sight, these insects contribute to the environmental health of our planet by pollinating plants along the way. Unfortunately, populations have been in serious decline as a result of habitat loss and a changing climate.

Keith Anderson is trying to change that. One day in the spring of 2017, he saw a monarch lay an egg. With his curiosity piqued, he went looking for and found about a dozen monarch caterpillars. The next day, all of them were gone. This motivated him to begin raising the butterflies indoors. Since that day, Keith has raised over 1,000 butterflies from the eggs found in his yard alone. He has shared chrysalises with Quarry Hill Nature Center, the MN Master Naturalists, and local schools. His work is inspiring others in the community to raise and release butterflies of their own.

Lincoln K-8 Faculty Beekeepers

Honey bees are all-star pollinators. The U.S. Department of Agriculture claims that managed colonies add at least $15 billion of value to U.S. agriculture annually through increased yields and quality harvests. With the overall health of the species in question, faculty members at Lincoln K-8 District-Wide School found a way to introduce their students to these amazing insects.

In May of 2018, the school purchased a Flow™ Hive and built a foundation for it to sit on. This style of hive allows the students to see what’s going on inside the hive without disturbing it. The school worked with the Boy Scouts of America to locate the hive at the Gamehaven Council Headquarters. Doing so provided more space for the bees and ensured the hive wouldn’t get hit by an errant playground pass. Additionally, the University of Minnesota Extension was crucial to the project’s success in educating the teachers on how to properly care for the bees. The school’s hive will serve as an active learning opportunity for many classes to come, fostering an appreciation, rather than a fear of bees.

Curt Tvedt

Curt Tvedt is a life-long learner with a passion for soil health. He has been incorporating conservation practices since he began farming decades ago, but as of 2015, Curt has learned that we can build soil back relatively quickly through no-tilling and cover cropping. For the past three years, Curt has planted soybeans into living rye in the spring and later crimped the rye to provide a mat of residue for the soybeans to grow through. This protects the soil from heavy rains and naturally suppresses weed growth. Eventually, he would like to increase his soil health to the point of not needing as many inputs (labor, fuel, fertilizer, etc.).

Curt has started peer-to-peer education groups to promote conservation farming. As a member of the Land Stewardship Project—an organization that promotes sustainable farming—he has hosted field-days to share his successes through presentations and demonstrations. Additionally, he has taken courses in microbiology to better understand processes that build organic matter back into the soil.

Sierra Student Coalition at UMR

The Sierra Student Coalition (SSC) at the University of Minnesota Rochester (UMR) believes that through teamwork and creative collaboration, citizens can contribute to scientific discovery and the advancement of a local policy designed to protect people and the environment. In March 2017, the SSC began collaborating with the following organizations to develop a community-driven air quality study:

The Rochester Air Quality Feasibility Project was modeled after an air quality study conducted by faculty at the University of Iowa (UI). SSC students talked extensively with the creators of the UI study and took their experiences into account when deciding research methods, materials, and the study’s structure. With the help of volunteers, the SSC collected air samples at multiple locations across Rochester in August and December of 2017. In 2018, SSC students worked with local physicians to analyze the data.

The Rochester Air Quality Feasibility Project found that levels of particulate matter in the air can vary considerably across neighborhoods in Rochester. The study provided preliminary data that supports the addition of more air monitors in town.

De Cansler

“People protect what they love, they love what they understand, and they understand what they are taught.” These words from Jacques-Yves Cousteau stuck with De Cansler throughout her teaching career and beyond. For many years, De used monarch butterflies donated by the University of Minnesota Monarch Lab, as a focal organism in her middle school science classes. The students were able to literally watch science come to life as the butterflies progressed through their life cycle’s various stages. In 2006, she furthered her monarch expertise by spending a year-long sabbatical in the U of M’s Monarch Lab. The knowledge she gained through the experience proved especially valuable once the Monarch Lab stopped distributing eggs and larvae to classrooms in 2008.

De began breeding and raising her own monarchs. She retired from teaching in 2010, but her work with the butterflies continued. De has delivered countless eggs, larvae, and chrysalises to schools and organizations across Southeastern Minnesota at no charge. She has also shared her knowledge with teachers across the country. Thanks to her work, thousands of students have a better understanding of the natural world around them.

Homestead Trails Neighborhood Association

In 2010, the Homestead Trails Neighborhood Association worked with the Rochester Parks and Recreation Department to establish a policy that allowed residents to plant vegetable and flower gardens on parkland and/or public lands. Once permission was granted for their garden, the neighbors began work clearing a lot at the junction of King Court SE and Neville Court SE in Rochester. The site had previously been used as on old construction dump site and was filled with concrete slabs, broken asphalt, old pipes, and more. The neighborhood received multiple RNeighbors Project Grants to rent equipment heavy enough to remove the debris. Fresh dirt and compost were brought in to improve soil fertility which allowed the neighbors to begin plans of establishing a community garden.

An average of 35 neighbors help with the garden each year and an estimated 55 individuals have been involved in the work since the project began. With time, sweat, and patience, the Homestead Trails Neighborhood Association transformed this piece of land from a waste site into a thriving food source and gathering space.

Key accomplishments:

Andrew Pruett

Andrew Pruett’s connection to Quarry Hill Nature Center goes back almost thirty years. At twelve years old, he would ride his bike to the Nature Center to help feed the animals. As a senior in high school, he cleared buckthorn from Quarry Hill Park’s oak savanna. These days, Andrew volunteers as a beekeeper and cares for the captive animals.

His passion for honey bees stemmed from his father, who kept bees and received subscriptions to the American Bee Journal—Andrew remembers reading copies cover to cover. Years later, his passion was reinforced by his future wife, an experienced beekeeper and former Wisconsin Honey Queen.

For the last eight years, Andrew has overseen bee care at Quarry Hill Nature Center. He feeds the bees, regularly checks on the queen, and monitors the overall health of the colony. Andrew also keeps three hives on his own property to supplement Quarry Hill’s hive if the population drops.

Since 2016, Andrew has helped care for the Nature Center’s captive animals. He has researched every animal in his care and readily shares his knowledge with the public. Andrew hopes his efforts will inspire the next generation to appreciate wildlife as much as he does.

New Report Shows that Solar, Wind, and Storage Can Competitively Power a Majority of Minnesota’s Electric Needs

Media Contact: Dan Thiede,, 612-626-0556

New Report Shows that Solar, Wind, and Storage Can Competitively Power a Majority of Minnesota’s Electric Needs

Minnesota can produce 10 percent of its electricity from solar by 2025 and 70 percent from solar and wind by 2050 at generation costs comparable to natural gas.

Building additional solar and wind capacity coupled with energy curtailment is less expensive than building long-term or seasonal storage.


Thursday, November 15, 2018, Saint Paul, MN: Minnesota has been ambitious in meeting its renewable energy goals: the state hit its 25 percent renewable energy by 2025 goal early this year using wind, solar, biomass, and hydro power.

A report released today finds that Minnesota could achieve 10 percent solar by 2025 at costs comparable to natural gas generation. Further, the report finds that expected cost decreases in solar, wind, and storage will enable Minnesota to achieve 70 percent solar and wind by 2050 at costs comparable to natural gas generation.

The Solar Potential Analysis Report, prepared by Clean Power Research for the MN Solar Pathways Initiative, includes several scenarios that model future renewable energy generation costs.

“This report shows that a renewable energy future is not only possible in Minnesota, but that the generation cost of solar, wind, and storage is competitive with natural gas generation,” said Brian Ross with the Great Plains Institute. “We also learned that coupling additional solar and wind capacity with energy curtailment when production is not needed eliminates the need for costly seasonal energy storage,” added Josh Quinnell with Center for Energy and Environment.

Key findings from the report:

  1. Solar and wind can serve 70 percent of Minnesota’s electrical load in 2050. Solar and wind can serve 70 percent of Minnesota’s load at generation costs that are comparable to the levelized generation cost of new natural gas generation.
  2. Additional capacity coupled with energy curtailment is considerably less expensive than, and a viable alternative to, long-term or seasonal storage in a high renewables future. Declining costs of solar and wind generation (<$20/MWh) will enable solar and wind to be economically curtailed during periods of high production and low load.
  3. Using other flexible generation resources in limited amounts support a high renewables future. The strategic use of other generation resources during brief periods of low-solar and low-wind production will significantly reduce the storage, solar, and wind capacities needed to serve Minnesota’s hourly load, reducing the generation cost for 70 percent solar and wind by nearly half.
  4. Storage is an important part of a high renewables future; it expands the dispatch capabilities of wind and solar assets. Sufficient quantities of storage smooth out the intra-hour variability of solar and wind.
  5. Shifting of key flexible loads may further decrease generation costs. Load shifting of new electric vehicle and residential domestic hot water loads demonstrated a potential 10-20 percent decrease in generation costs by moving the consumption to different times in an hour, day, or week.


“The MN Solar Pathways Solar Potential Analysis Report demonstrates that it’s possible to find an economical pathway to higher renewable generation,” said Jeff Ressler, CEO of Clean Power Research. “Critical to this project was the use of time-correlated solar, wind and load generation datasets in advanced software tools to more precisely see the effects of different scenarios, such as varying amounts of solar, wind and storage capacities.”

Mark Ahlstrom with Energy Systems Integration Group and a Technical Committee member who contributed to the development of the report said, “The MN Solar Pathways Solar Potential Analysis approach is conservative but relevant, and there is a growing body of good work that shows that penetrations in the 70-80 percent renewable range are quite feasible and not unduly expensive. Best of all, we have the key technologies today to get to 70 percent renewable energy and to accommodate massive electrification of other energy sectors.”

About MN Solar Pathways: The initiative, sponsored by the U.S. Department of Energy Solar Energy Technologies Office, is a three-year project designed to explore least-risk, best-value strategies for meeting the State of Minnesota’s solar goals. As part of this aim, the Pathways Team is modeling renewable generation costs, examining ways to streamline interconnection, and evaluating technologies that can increase solar hosting capacity on the distribution grid.

MN Solar Pathways is led by the Minnesota Department of Commerce, Great Plains Institute, Center for Energy and Environment, Clean Energy Resource Teams, and Clean Power Research. 20 other organizations, from utilities to advocacy groups and from corporations to local governments, have contributed their time and expertise in the review and creation of reports for the initiative.
