Reality vs. Theory in RPS Costing

Despite a steep fall in wind-energy prices [1], there is still some dispute whether wind is competitive with conventional fossil fuels. There is a simple way to resolve this issue – compare the prices for electricity generated by wind with that by conventional fuels. A calculation made for the Great lakes region (IL, In, MI, Oh, & WI) found that wind was cheaper, with the difference about equal to the wind subsidy [2].

Analyses that claim wind is expensive use the levelized cost of energy (LCOE), which estimates theoretically the cost to produce electricity using various technologies. The most recent LCOE data show wind to be competitive with fossil fuels, even without the subsidy [3, 4] – the same conclusion reached by price analysis. However, there are two reports [5, 6] that claim that wind causes Ohio’s renewable energy portfolio to be expensive and harm the state’s economy. Serious errors exist in both reports:

  1. LCOE greatly overestimates the price of electricity produced by wind [7].
  2. LCOE values differ from report to report [3, 4]. Both Ohio reports [5, 6] used high LCOE values, without justifying their choice.
  3. References [5] and [6] both use out-of-date LCOE data. As noted above, the 2015 costs show wind to be competitive without subsidy, making the portfolio cost-free using their assumptions.
  4. Portfolio requirements are mostly fulfilled by renewable energy certificates, not by wind farm construction [8].

 

There was a time, several years ago, when wind was expensive. Politicians opposing renewable energy pretend that those days are still with us. They need to address a simple question: if it costs $75 per MWh to produce wind electricity [3], how can the producer sell it at $50 per MWh [3], lose 33 cents on the dollar, and still stay in business?
