In my area of OH, they have a grid tie program. I chose not to be part of it. I have electric utility at my place. My solar set up is separate from the utility. The last few months I've been able to use zero KWH grid utility use, but continue to receive a utility bill. It shows on the bill 0 kwh but charged $12.32 each month. They call this a "Line Distribution Charge". So, I have no desire to have my line cut at the road because you just never know who may need the convenience of the grid. I figure it is costing me .41 cents a day to keep my utility. I am posting this to see if this is customary across the country or may be I'm in a lucky state not being charged even more or less depending on others.
