We analyzed the best financial approach to build this project • NPV: Net cost of ownership by City discounted at 5% over 25 years • Savings: cost to City of third -party ownership over 25 years as compared to owning it at current rates PROPRIETARY AND CONFIDENTIAL RECOMMENDATION • Given the parameters of this study, current electric rates, and future expected projected rate increases Bluestem Energy Solution's recommendation is to move forward with a third party public private partnership given: • The City of Iowa City wants to meet their greenhouse gas emissions goals • The City of Iowa City wants to be a "green" community • Bluestem anticipates the City of Iowa City's electric bill increasing $4,500 to $7,000 per month if the City choose to go forward with a third party public private partnership • Given the current economics, Bluestem Energy Solutions suggest the City of Iowa City looks into increasing the size of this project by partnering with the University of Iowa or Eastern Iowa Power and Light • Partnering with the University of Iowa could help increase the overall size of the arrays thus driving economies of scale • Partnering with Eastern Iowa Power and Light could lead to significant more greenhouse gas emissions, given Eastern Iowa Power and Light's infrastructure and that Eastern Iowa power the City's largest user and biggest greenhouse gas emitter.
