Wind Capacity Factors

Despite claims to the contrary, wind capacity factors have remained relatively constant over the years at about 1/3 (1). Over the first six month of 2015, the average U.S. capacity factor was 0.32 and that for Ohio was 0.34 (2).

Computer Predictions Regarding Renewable Energy are Unrealistic

Testimony at the final hearing of the Electric Mandates Study Committee predicted dire economic consequences of resuming the timetable in 130-SB310. These warnings were based on two reports (I, ii) that used a computer model of a state’s economy. However there were two serious omissions in both studies:

  1. Neither report includes cost estimates for RECs. The renewable energy goals are being satisfied by the purchase of renewable energy certificates (REC), which are considerably cheaper than the electricity itself.
  2. The efficiency goals are not included in either analysis. Efficiency has led to a net saving for Ohio ratepayers.

There is a separate issue as to whether the reports give realistic results for the situation they are calculating. For example, ATI (ii) estimates a cost range of $67-100/MWh for 2016. The 2015 price is about $20 (iii).

Renewable Energy Does not Hurt Economically

If renewable energy causes financial harm, the effects should show up in economic data. Since Ohio has the least renewable energy of any state in our region (1), compared to the other nine states we should have

  • the lowest unemployment rate; Ohio actually has the fifth lowest. (2)
  • the highest rate of job creation; Ohio actually ranks sixth highest. (3)
  • the best recovery from the recession: Ohio actually ranks third. (4)
  • the lowest utility rates: Ohio actually has the fourth highest. Having more renewable energy does not increase rates(1)

Apparently, there are no benefits to Ohio having little renewable energy.
