We empower communities and their members to adopt energy conservation, energy efficiency, and renewable energy technologies and practices for their homes, businesses, and local institutions. B3 Benchmarking – The Hastings Opportunity 3 Energy Efficiency Initiatives 4 B3 Benchmarking – Red Wing 5 You’ve Got Options! Green Tariffs Xcel Renewable Connect Green Pricing/RECs Community Solar Gardens Third-Party Solar Financing Direct Purchase Green pricing doesn’t have to 5-10 years. Fine line between recs, green pricing and green tariffs. Differences in the structure of the agreement. Other utilities have green pricing that are similar or you could go out on the market and by recs. 6 Green Tariffs & Community Solar Gardens High level comparison of attributes. Benefits to both, and yet some differences. Can do a combination. Xcel Renewable Connect – governments can choose a subscription size.

SUBSCRIBERS: individuals or groups to get solar power 3rd Party Operator develops & runs garden. They also maintains relationship w/ subscriber for payment. Utility provides subscriber w/ bill credit. Subscriber Requirements The following rules apply to all Solar*Rewards Community subscribers: • A subscriber must be an electric retail customer of Xcel Energy • Subscriptions must not exceed 120% of your average annual electric energy usage • Subscriptions must not exceed 40% of a single garden • Subscribers will be provided a monthly credit on their bill. The credit will be determined on a dollars per kilowatt-hours produced ($/kWh) basis by Xcel Energy. https://www.xcelenergy.com/staticfiles/xe-responsive/Admin/Managed%20Documents%20&%20PDFs/MN-SRC-Subscriber-FAQs.pdf 11 Subscription Models 12 Are Subscriptions Available? Current rules allow subscriptions from CSGs in your home county or an adjacent county. Per Xcel’s list, there are 7 subscriptions available in surrounding counties.

In talking to 4 different solar subscription providers, the ARR rates are dwindling and we are quickly losing out on obtaining the best rates. I think at this point, we would be looking at proposals that would have a combination of ARR and VOS. I was hoping you would address the perception of risk that Councilmembers have had in the past with the ARR rates. They believe there is a huge risk that locking into ARR rates are going to put the City in jeopardy of paying more for a solar subscription then a regular Xcel energy rate. If you would please take several minutes to explain electric utility rate trends over the last 30+ years and highlight how the likelihood that an ARR with a 1 escalator would dip beneath the regular rate in the long term is remote. That is the issue that killed it last time. They just didn't understand the economics behind it and the staff didn't take the time to figure it out themselves. 23
