MidAmerican energy company says it plans to install six more aircraft detection systems to keep the red warning lights at the top of wind turbines off until they are needed. MidAmerican spokesman Geoff Greenwood says they started testing the system in 2023. “It has really gone well. It dramatically reduces the amount of lighting at the wind farms where we have this system installed, and we’ve gotten a lot of public compliments out of it. People notice it. They notice that the lights are off at night,” Greenwood says.
They have 38 wind farms in 34 counties. The blinking red lights are required from dusk until dawn by the F-A-A so planes can see the wind turbines at night. Greenwood says the warning system is simple, and they’ve found it keeps the lights off 95 to 98 percent of the time.
