The City is working on several new projects to reduce energy usage and improve public infrastructure.

Wastewater Treatment Efficiency – The City is working with an engineering company to design a more efficient process at its wastewater treatment plant. Currently, the City uses rotors to maintain a certain level of dissolved oxygen throughout the treatment process. This project will save energy and money by using dissolved oxygen sensors to control and optimize operation of the rotors. The City expects that this improvement will save $15,000 and 240,000 kWh annually.

Exterior LED Lighting – City staff are working on an exterior LED Lighting retrofit for the Rogers Wines and Spirits building. Compared to the current metal halide lights, LED lights use 75% less energy and last 5 times as long. This not only saves money, but reduces staff time required to change light bulbs each year.

Solar Trail Lighting – The City is researching solar trail lighting that would be installed on Rogers Drive. Instead of being connected to the grid, these lights would be powered by solar energy that is collected during the day and stored for use at night. This would save the city from paying for electricity entirely.

Water Conservation – City staff and an irrigation specialist have been meeting with local businesses to inspect irrigation systems and install rain sensors or smart controllers. New systems are expected to be installed by the end of May, resulting in a reduction of treated water being used for lawn irrigation.

The Minnesota GreenStep Cities program helps Minnesota cities to achieve sustainability goals through the implementation of 28 best practices, which are focused on cost savings, energy use reduction, and encouraging innovation. For more information, visit GreenStep's Website.

June 2012:  The City expects to save over $22,000 annually as a result of its actions in the Buildings and Lighting Category. Download the report for more details.

May 2012:  The City received notice that it is expected to receive recognition as a Step 2 GreenStep City at the League of MN Cities Annual Conference in June.

February 2012:  City staff entered data on the GreenStep Cities website, which shows actions that the City has completed to date. Staff are continuing to update data as actions are completed.

December 2011:  The City of Rogers became a Minnesota GreenStep City.

The City of Rogers is making progress on the following initiatives to make its public buildings more energy efficient:

April 2012: The City replaced its remaining incandescent traffic signals with LED bulbs, leading to 100% LED traffic signals city-wide. LED traffic signals last longer and use less energy. LED signals are also made up of several tiny lights, so if one light burns out, the signal will continue to operate.

February 2012: The City completed installation of a new Building Automation System at the Rogers Activity Center. This project is expected to save the City over $400,000 in energy costs over the next 20 years.

November 2011: The City began tracking its public building energy use with the State of Minnesota's B3 Benchmarking program. This program helps the city to identify which buildings could yield significant cost-savings through energy conservation projects such as recommissioning, lighting upgrades, and building envelope upgrades.

Summer 2011: The City installed new, energy-efficient floating pond aerators at its sludge storage pond, yielding annual savings of $1,700.Floating Aerator

Since 2009: The City has installed energy-efficient lighting in the following buildings:

Lamp Installation

  • Police Station
  • Municipal Liquors
  • Rogers Wines and Spirits
  • Public Works and City Hall
  • Fire Station and Community Room

This new lighting gives off a better quality of light and is expected to save the City over $7,800 annually in energy costs.
