Quick Answer
Yes, you can sell excess energy generated by a wind turbine to the grid through a process called net metering, which allows your energy meter to run backwards when you're producing more energy than you're using.
Understanding Net Metering
Net metering is a regulation that allows homeowners with on-site renewable energy systems, like wind turbines, to sell back excess energy to the grid and offset their electricity bills. In the US, for instance, net metering policies are adopted by over 40 states, with some states having more favorable policies than others. To be eligible for net metering, you typically need to meet specific system size requirements, which can range from 10 to 50 kilowatts (kW), depending on the utility company and local regulations.
Installing a Wind Turbine for Net Metering
When installing a wind turbine for net metering, it’s essential to consider factors like turbine size, location, and system configuration. A typical residential wind turbine for net metering might be a 5-10 kW machine, which can generate between 20,000 to 40,000 kilowatt-hours (kWh) per year. To ensure optimal performance, you should also install a suitable inverter, such as a grid-tie inverter, which can convert DC power from the turbine into AC power that can be fed back to the grid.
Connecting to the Grid and Selling Excess Energy
Once your wind turbine system is installed and connected to the grid, you can sell excess energy to your utility company at the prevailing retail rate. For example, if your electricity bill is $0.15 per kWh and your turbine generates an average of 30 kWh per day, you could potentially save around $45 per month on your electricity bills. However, the actual savings will depend on various factors, including your energy usage, turbine performance, and local electricity rates.
