I live in VA. At least if you purchase your generation through the main electric utility, Dominion Energy, there are fixed rates. What these rates are depend upon how much you use per month and the time of year. For rates the year is broken into 2 periods. October - May and June - September. Rates are in general highest for use over 800kWh in a month between June & September since it is the highest usage period statewide. My last bill the average rate was about .11 c/kWh. I used 915 kWh. Last July I used 672 kWh and my rate was about .12 c/kWh.
