23 Vision Shared: Efficiency and Renewables Energy Efficiency MEUs have been EE leaders since 1970s, models for IOUs Examples Osage and Cedar Falls They also utilize local professionals for most services NewGen figures 5% EE/LM/LMI, versus Alliant 3.6%, 2016 Renewable Energy Also RE leaders, wind, community solar Local ownership not in IOU interest NEM and Winneshiek Shared Solar DMEU could start day one 30% clean Per web site, Alliant at 15%+ 23

24 Vision Shared: Faith, Stewardship, Community Values Public Power carry rights and responsibilities of local ownership Climate Change is a responsibility to put our core values to work Luther investments reflect mission: to practice joyful stewardship of the resources around us First United Methodist Church, First Lutheran Church, Good Shepherd, others making similar values investments We do not have to choose between what is good for our planet and what is good for our economy. When combined with energy efficiency and solar, clean energy investment creates opportunities to alleviate rural poverty through good-paying jobs and other economic benefits to small communities Iowa religions leaders statement Accepting responsibility for the good of future generations and the welfare of the disadvantaged in our present generation are twin and inescapable ethical obligations. Municipal electric utilities offer the opportunity for important local efforts to eliminate energy poverty, reduce inequality, and remove the barriers to equal opportunity for all our residents. -JMS MEUs also leaders in programs for economically disadvantaged, (LMI) NewGen report includes 5% budget items for these EE/LM/LMI programs 24

25 Vision Shared: Innovation, Locally-Owned Microgrids subset of larger grid New Hampton, Farmers Electric Co-op, Osage Energy Storage batteries and more Renewables plus batteries can provide power during critical outages and do so almost indefinitely Cyber-security, major grid vulnerability by having the appropriate generation resources and digital perimeter defined, a municipal utility would be able to isolate itself physically and to reduce its network exposure significantly. 25

26 Next Steps Community Referendum Petition to Iowa Utilities Board Costs included in NewGen pro forma IUB sets territory IUB sets value of acquired assets IUB ruling could be litigated Franchise agreement can wait 26

27 Conclusions MEU could operate at lower overall rate as compared to Alliant/IPL IUB application will require further analyses 27
