Ohio Electricity Goals

Ohio now uses about 90% coal, 10% nuclear, and <1% renewables. The goal for 2024 from 127-SB221 is 12.5% renewables and 12.5% 'advanced', which means coal, e.g. sequestration. So we will be left with over 3/4 coal assuming the two operating nuclear plants are still on line.(New nuclear counts as 'advanced', but there are no plans for an additional plant in Ohio).

Assuming that we hold down consumption, we will need to build about 4 million kW of capacity, costing at least $10 billion, assuming >$2,500/kW construction costs.

Solar Goals for Ohio

Ohio now has 33.8 GW of electric power. 127-SB221 specifies 0.06% solar by the end of 2012. This amounts to about 20 MW of solar. The minimum goal for solar in HB113 is 1000 schools with 50 kW = 50MW. So the bill requires 2.5X the goal for 2012. Actually, it would satisfy the 2015 goal for solar (50 MW = 0.15% of total). The ultimate solar goal is 0.5% = 169 MW by the end of 2024.
