This is not a show-stopper. In my state (TX), electric utilities have
been strictly segregated into generation, distribution and retail. When
I have a problem with my service, I call my retailer, who puts in a
ticket with the distributor (i.e. grid operator). However, since the
distributor has an equal relationship with _all_ retailers, rather than
also having a retail arm itself (as in the telco model), there is no
service problem. If anything, service is _better_ than when
distribution and retailing were done by the same (monopoly) utility
company because there are now formal SLAs and penalties.

Wrong. As soon as retailer 2 puts in the connect order, everything gets
switched over within one business day. The distributor stops billing
retailer 1 because they're no longer in the picture.
Now, if different CPE is required (not an issue for electricity), then
the customer would notice that the CPE from retailer 1 suddenly stops
working. They would then unplug it and follow the directions that came
in the box with the CPE from retailer 2. No truck roll needed, unless
they paid extra for that. (In a slightly different space with similar
costs, prices and volumes, one carrier said rolling a truck for
installation would blow their profit margin for the entire year.)
