Wind and Solar Installations
Wind and solar power are a growing part of our country's diverse energy mix, and it's now easier than ever to put up your own wind turbine or solar panels.
Heartland has a handful of members with wind and solar resources connected to our system, all benefiting from our net metering policy. Because their electric meters run forward and backward, it's possible for members to "bank" excess power generated and offset power consumption later in the monthly billing cycle.
Heartland's net metering policy has a monthly sweep, so any "banked" power is lost at the end of the billing cycle. Therefore, when deciding how big a wind or solar system to install, it's important to compare the system's expected power generation to your home's monthly power use.
For example, the Skystream 3.7 wind turbine that Heartland helped install at Greenbush has a rated output of 1.8 kilowatts. Because this part of Kansas is considered Class 2 with average wind speeds of 12-14 mph, that turbine averages about 300 kilowatt-hours per month. Live data from the turbine is available here. You may also want to consult the 30-meter Kansas wind map.
A 5 kilowatt PV solar array will generate between 300 and 700 kilowatt-hours each month in this part of Kansas. Solar and wind systems will have high months and low months and predicting those will be important to a successful installation. This website from the National Renewable Energy Laboratory can help you find out how much power a PV solar array will generate at your location.
For members who install renewable generation significantly more than they expect to use during a typical month, an alternate parallel generation rider can be chosen which pays members for their power generated at a rate of 150 percent of the cooperative's monthly system average cost of energy.
Any wind or solar systems installed by Heartland members must be inspected by our staff before thay can be interconnected to the power grid. A simple application form and $100 fee are required for systems 10 kilowatts or smaller. All wind and solar systems interconnected with the power grid must have safety measures in place to make sure power is not put back on the grid during a power outage. An accessable manual disconnect switch must also be included so that Heartland crews can disconnect the system when working in the area.
Systems larger than 10 kilowatts have a more complicated approval process due to concerns about the produced power on the cooperative's infrastructure. For very large systems, members will be required to cover the costs of an analysis conducted by an independent engineer.
