Solar Power

Our diverse mix of energy resources helps us maintain low-cost, reliable service.

Hoot Lake Solar

In August 2023 we completed a 49-megawatt solar project in Fergus Falls, Minnesota. Hoot Lake Solar’s nearly 130,000 solar panels will produce enough energy to power approximately 9,000 homes annually.

Small scale solar

Our two small solar facilities, Blue Heron Solar near Ottertail, Minnesota, and Blue Jay Solar in Jamestown, North Dakota, began generating energy in 2020. They're almost 40 kilowatts in size.

Publicly Owned Property Solar program

To help meet the 10% carveout in the Minnesota Solar Energy Standard, we offer our Publicly Owned Property Solar program to Minnesota customers. This program offers cash incentives to publicly owned facilities that install qualifying solar photovoltaic (PV) systems.

Home and business solar installations

As an Otter Tail Power Company customer, state incentives, special rates, and tax credits are available for qualifying solar installations connected to our power grid. And if you don’t consume all of the solar energy you produce, we’ll credit the excess generation on your bill through our Net Metering Rate. If your solar PV system capacity is less than 40 kilowatts (kW), we purchase excess generation at retail rates. If your solar PV system capacity is greater than 40 kW, we purchase excess generation at our avoided cost.
