Sounds like they are losing a lot of revenue by doing this. Just wait, your rates will be going up to cover their "shortfall"
Our solar guy told us they will be increasing revenue because they charge on a 3 tier system. The more power you use the more it costs per kwh. The new meters measure more accurately so you are put into a higher tier faster. In our area it’s pretty much the norm for the bill to go up when the meter is installed. There were lawsuits in Bakersfield over it.
