Ramping up idle fees is how they will force the holdouts onto electricity. $120/mo is insane. We pay about $15/mo but I can certainly see it going up
In more organized places they are a) ensuring new subdivisions are gas free from the start and b) disconnecting large areas of older connections simultaneously to minimize overheads.
Instead of just whacking people with the stick (and leave the installations entirely up to the private sector who have a terrible history of being conmen when it's the government providing grants to the businesses)
