No problem. The spin-offs took place around 2002-2003, IIRC. Consumers and DTE were pushing for deregulation in the late 90s, so the MPSC said they had to divest either their generation assets or their transmission assets. Both utilities chose to keep the generation and sell the transmission businesses. Deregulation turned out to be a big flop and I think both companies wish they had their transmission lines back. Be careful what you wish for. As Paul Harvey used to say, “…and now you know the REST of the story.”
In other news, both Consumers and DTE Electric are switching to the MPSCS. DTE Gas is already on MPSCS, but only uses encrypted talk groups. I believe Consumers and DTE Electric will be mostly unencrypted with a few encrypted talk groups. Consumers is already on-the-air with MPSCS. DTE Electric is a few months out. Both companies will have a change-over period with patched comms between their old and new systems.
