Alliant Energy Interstate Power and Light - Residential Renewable Energy Rebates

September 17, 2014

Summary

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. Projects must be placed in service within one calendar year from the date of the online screening.
Customers can receive a higher "Energy Efficient" rebate rate for wind and solar PV if the homeowner meets one of the following criteria: 

1. The homeowner installs all upgrades with a five-year or less payback period as identified in a Home Performance with Energy Star audit
2. The home passes the Alliant Energy's New Home Construction requirements
3. The homeowners annual electricity usage is less than 6,500 kWh

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
