Certainly an antiquated installation that runs a huge(used to be anyway) industrial area. It will be months before the whole story is known. How after deregulation the free market is going to invest in new lines is beyond me.
We certainly are addicted to electricity and its benefits. Mainers learned that in 98 when ice took down lines thruout the state and folks went without for days to weeks
