Consumer renewable energy charges required by Ohio law (130-SB310), have remained relatively constant over the years, varying from 50 to 70 ¢ per month even as the renewable energy requirement has risen from 0.5 to 2.5 percent. Overcharges in 2014 and refunds in the first part of 2015 (1) obscure the relative constancy.
I assumed that the typical monthly usage is 1000 kWh, as does PUCO (1). Consumer charges are calculated as in Ohio Administrative Code Section 4901:1-21-19 (B).
