The Alliant Energy Renewable Cash-Back Rewards program offers its electricity customers rebates for solar photovoltaics (PV), wind, and solar thermal water heating systems. Natural gas customers qualify for the solar thermal water heating reward.
In order to apply for the program, customers must first use the online self-assessment tool. Alliant Energy will then contact customers to schedule a Home Performance with Energy Star audit and a site assessment to determine renewable energy potential.
Customers can receive a higher "Energy Efficient" rebate rate for wind and solar PV if the home meets certain energy efficient objectives, as determined by the Home Performance with Energy Star audit. Alliant Energy customers can also receive energy efficiency rebates through the Energy Efficiency Rebate Program in order to meet the energy efficient objectives.
Rebate rates are as follows:
Energy Efficient Solar PV: $1.25/kWh x estimated first year output
Standard Solar PV: $0.75/kWh x estimated first year output
Energy Efficient Wind: $0.75/kWh x estimated first year output
Standard Wind: $0.25/kWh x estimated first year output
Solar Thermal Water Heater (electric): $0.35 x annual kWh savings
Solar Thermal Water Heater (natural gas): $2.50 x annual therm savings
