Two acronyms both for city electrical utilities, and they're causing some understandable confusion:
The Ann Arbor Sustainable Energy Utility (SEU) was already approved in 2024 and is already running on a small scale. For now it's not much difference from installing solar panels and batteries on your house, except that the city handles the installation and maintenance and you just pay monthly. It's a supplement to DTE rather than a replacement.
Ann Arbor for Public Power (A2P2) is a group of people who think the city should take over the city's electrical infrastructure completely. That would be a more complicated, longer-term project, requiring the city to buy and take responsibility for all the existing electrical infrastructure from DTE. The city commissioned a study to look into this, then a council vote to continue the work with a more in-depth study failed narrowly. A2P2 is trying to revive the effort with a ballot initiative; currently it looks like they may fall short of the signatures required.
I'm not a fan of the ballot initiative, which I think goes about things backwards by setting up a new board to run the utility (which we would need to elect members to), before we've finished figuring out the cost and effort that would be required to continue.
