For the princely sum of $10 a month between June and September, NIPSCO just informed me by mail that they would like to be able to shut down my AC compressor for 15 minute intervals at their convenience. I think not. I run a number of servers from my residence and I'll keep my AC under my own control.
In the bad old days of telecoms, it was not clear at all that the wire and phone equipment that you paid for were actually yours. In fact, AT&T asserted nothing hooked up to its network belonged to anybody but them. It took a number of lawsuits to and an anti-trust action to settle that. I do not welcome the return of that world via the electric companies turning your things off at their convenience.
