Policy -Strategy Option Description, January 30, 2009

Like many states, Iowa faces significant challenges on the energy front.  Energy prices have  surged in recent years to record levels before declining precipitously following the financial  crisis that broke in September 2008.  Despite this pullback, the fundamentals that contributed to  higher energy prices are expected to return once economies rebound. Oil prices have gone up  on increased demand, driven in large part by developing countries such as China and India,  whose economies have been rapidly expanding.  Natural gas prices have also fluctuated  dramatically, trading in a range from $4.50 to $13.00/MMBtu over the past year, but are unlikely  to remain at low levels over the long term.  As shown in our analysis later on in this report, the  difference in levelized cost of electricity from a gas‐fired combined cycle plant can vary  significantly depending on the fuel cost.    Dependence on others for energy supply involves significant risks and uncertainties.  Thus, if  Iowa wishes to reduce its dependence on others – or even achieve energy independence – Iowa  needs to pursue actions on a numbers of fronts.  Following the status quo is not an option.    A carbon tax would change the energy landscape in Iowa.  Since Iowa is currently 75%  dependent on coal, a carbon tax could mean that generators, and in turn ratepayers, could be on  the hook for higher electricity prices, though it remains to be seen exactly what the tax scheme  will be.  In addition to existing plants, a carbon tax would also have a significant impact on the  cost of new generation plant.  We have modeled carbon taxes ranging from $0‐50/ton in our  analysis in the Appendix.  However, if a more aggressive carbon policy came into play resulting  in market values of for example, $100/ton or even $200/ton, then that could raise the cost of coal‐  and gas‐fired generation significantly, making alternatives such as wind more economical.
