Return on Investment

Something doesn't add up here, at least from a business perspective. They say it will cost $13 million dollars, and produce 2.6 million kilowatt hours per year.

2.6 million kilowatt hours at say $0.14/kwh (which is high) is only worth about $364,000.00. Divide that into the $13 million cost, and it takes over 35 years to get a positive return on investment, not taking into account and future costs for repairs and maintenance.
