Residential Wind Turbines

Many cooperative members are interested in owning renewable energy systems, particularly wind, for their homes, businesses, or farming operations. A common question asked is how much money can be saved in future electricity costs in comparison to the investment.

There are many variables that have an impact on the economic viability of a small wind machine. This model allows the user to input many of these variables including:

• project costs

• electricity generated
• retail electric rate
• project life
• grants and loans
• O&M costs
• electricity consumed
• utility's avoided cost of generation
• discount rate
