Best Practice Action 26.6
GreenStep City Best Practices: Resilient Economic and Community Development
Renewable Energy No. 26
Remove barriers to and encourage installation of renewable energy generation capacity.
Best Practice Action Detail
Best Practice Action 6
Report installed private sector-owned renewable energy/energy efficient generation capacity with at least one of the following attributes:
a. Fueled by sun, wind, or biogas.
b. Fueled in part or whole by manure or woody (EAB) biomass, optimized for minimal air and other environmental impacts and for energy efficiency and water conservation.
c. Distributing heating/cooling services in a district energy system.
d. Producing combined heat and power; using a microgrid.
e. Energy storage integrated into a renewable energy installation.
- Project assistance, case studies and technical information is available from MN's Clean Energy Resource Teams and from the MN Renewable Energy Society. See also the Solar Directory web site to find produce and service companies that can help plan, implement and manage clean energy projects.
- The Great Plains Institute works on manure digesters, biogas and biofuels. And although not technically a renewable fuel, landfill gas is increasingly captured for energy generation in Minnesota.
- District Energy St. Paul, one of several combined heat and power (CHP) plants in Minnesota, runs North America's largest hot water district heating system, in addition to distributing chilled water, and is fueled in part by wood waste. In March 2011, they added North America's largest solar thermal production to the system. District Energy St. Paul's for-profit consulting, operation, and management firm is Ever-Green Energy.
- See background on microgrids and the role of microgrids in helping to advance the nation's energy system and the in-depth Minnesota Microgrids: Barriers, Opportunities, and Pathways Toward Energy Assurance (Microgrid Institute: 2013).
- In 2016, a microgrid powering a new Bloomington office building went online. 2021 energy legislation included funding to expand microgrid testing and hands-on educational opportunities at the University of St. Thomas.
- Increasingly tied to microgrids is energy storage (BPA 29).

Fond du Lac Band of Lake Superior Chippewa -
Date action report first entered:
Date of last report update:
Year action initially completed: 2014
Implementation details:
Fond du Lac is working to support community members in installing renewable energy systems in residential homes. Currently, 4 residential 3kw solar electric power systems, 1 solar electric hot water system, and 7 solar hot air systems have been installed. Together, these systems generate 13.5kw of renewable solar energy. FDL is in the process of designing a zero net energy home.
Outcome measures/metrics/money saved:
Cost data for these systems will be used to develop a model to apply these systems to sites of different scales and individuals with varying budgets. Performance data from these residential systems will be used to guide the process for designing additional systems.

Year action initially completed: 2016
Implementation details:
The City is currently coordinating with two potential solar farms in the area. One smaller, approximately 1 acre array will be located on the School Sisters of Notre Dame and Loyola Catholic School campus and will be used to service the campus electrical needs as well as for educational purposes. Approvals for this project area anticpated by July 2014. A second, larger, active 47-acre solar array adjacent to the eastern boundary of the City is currently in planning stages and would produce 5.5 megawatts of electricity. Completion of this project is slated for 2016.

Implementation details:
The 100 MW (AC) North Star Solar Project is located in Chisago County, Minnesota – approximately four miles southeast of North Branch, MN. The project connects to the grid at the Chisago Substation, a point of significant transmission infrastructure and strong electrical ties to Xcel Energy load. The North Star Solar Project provides Xcel Energy with a cost-effective and efficient solution to meeting their 1.5 percent solar energy requirement in Minnesota. The Project was approved by the Minnesota Public Utilities Commission. The North Star Solar Project is the largest solar energy facility in the Midwest, producing enough energy to power approximately 20,000 homes.

Red Wing -
Date action report first entered:
Date of last report update:
Year action initially completed: 2016
Implementation details:
In 2016, the City of Red Wing entered into a solar garden subscription for 5,737,500 kWh annually with solar garden provider Innovative Power Systems (IPS). The subscription should come near to providing 100% of the City's electrical use. IPS has built its first solar garden at large site provided by the Red Wing School District. The new 5 MW solar array recently went into production and the City has begun purchasing solar power in January 2017. Then new RW School District garden will supply 57% of the City’s solar garden subscription.
Outcome measures/metrics/money saved:
The rest of the City's solar subscription will come online when IPS has finished building more gardens. The solar garden subscription is a 25-year agreement which will save the City a conservative estimate of $6.6 million.

In 2006 Winkelman's Environmentally Responsible Construction (WERC) installed a small wind turbine on the Hunt Utilities Group campus in Pine River. The turbine was made possible in part by a $20,000 grant from Minnesota Power. In addition to the project description linked to below, you can see a Lakeland Public Television short on the HUG turbine here:
http://www.ecowerc.com/projects/audio_video/werc-hug-nibbe-sm.wmv *** Also, the community's GreenStep Task Force has been actively looking into a small hydroelectric power system for the dam on Norway Lake. So far we have obtained an initial feasibility report from Northland Engineering, and investigated possible safety and environmental permitting issues with the help of the DNR and other partners. *** Finally, the Pine River Area Sanitary District, a private entity that treats much of Pine River's wastewater, has solar hot water panels installed on its facility. (Note that this is "renewable energy generating capacity," but solar technology isn't included in the list of attributes specified in this Best Practice action - so the PRASD panels technically don't fulfill this action. Still, it seems like progress worth mentioning!) The Pine River GreenStep Task Force and RREAL are planning to encourage PRASD to fix a problem with their hot water panels, which currently are broken.

Presented in February 2012 to Kepware Technologies, Inc. for its support of a building automation system at Cascade Meadow. In order to bring data from power production systems, building power consumption meters, and other building mechanical systems together into one database, Cascade Meadow looked to Integrated Technology Engineering, a local firm, and Kepware. Today data from three separate systems can be monitored from one central dashboard, providing instant information about the energy efficiency of the Center – information that’s shared with visitors to the site and used for educational forums.
