Clean Energy Choice

The City of Chaska has improved its renewable product offering to customers!  The new Clean Energy Choice is an affordable, low-cost way for residential electric customers to support renewable energy. The program offers residential customers with the option to elect to have 50%, 75%, or 100% of their electricity from renewable sources. This is in addition to the 17% renewable energy that is provided to all MMPA customers, as required by Minnesota law.

Cut-In Speed

The cut-in speed is the minimum wind speed at which the wind turbine will generate power. The cut-in speed for Chaska’s turbine is 12 miles per hour or just over 5 meters per second.

Rated Speed

The turbine’s rated speed is the wind speed that results in the optimal power output for the turbine. When the wind speed exceeds the turbine’s rated speed, the turbine’s power output stops increasing and actually begins to decrease with higher wind speeds.

Cut-Out Speed

Wind turbines automatically shut down in very windy conditions, typically greater than 50 mph, to prevent turbine damage. The speed at which the turbine shuts down is called the cut-out speed.

The MMPA has a great website for exploring wind power, which we’d encourage you to visit.
