Additionally the regulations between the two are not the same.

For example, in my home state of Massachusetts, for-profit utilities are required to participate in the state mandated home efficiency subsidy program, MassSave and add surcharges to the delivery charge, to a state-wide cost of $4.5 billion for 2025 - 2027.

Municipal utilities are exempt.

We’re at the bottom of the list on this post, because it’s looking at recent inflation, but municipal utilities cost much less in Mass. But there are many components to this difference.
