Let's logic out this plan.
If my power is our for more than 12 hours, I get a free month of power. That sounds good on the surface for the consumer.
But. If a catastrophic issue occurs, and the company knows it will have to be out more than 12 hours, then they know they are not getting paid for the month by the people in that area. So, when deciding how to fix it, as the company, knowing you already have lost out on a month's revenue, do you throw multiple crews and overtime at it to get it fixed? Or do you take your sweet time, make sure you're not paying overtime, and simply ensure the power is back on by next billing period?
Do you ever quit thinking? It's Sunday! -
