Federal energy experts, the Rural Utility Service, have stopped allowing federal tax dollars to be invested in these coal plants because they are risky investments. In large measure this is due to impending costs imposed due to new carbon regulations.
Federal finance experts at the Treasury Department have ignored this energy expertise and issued no guidance to bond investors, as if the risk to a federal tax dollar were somehow different than a bondholder's dollar.
Our credit rating agencies seem equally confused. In your article a representative of Moody's defends a recent bond disclosure for a new coal plant because the offering document contains some discussion of carbon risk. The disclosure he defends ignores the same worrisome set of credit risks that Moody's warned about in February 2008 in a special report on climate risk.
Developers of coal plants and utilities face not only the risk of new carbon regulations and the costs from them, but they also face compliance costs with regard to sulfur dioxide, mercury and other air pollution requirements.
The recent ash spill in Tennessee has added future regulation of ash disposal onto the list of new costs. The volatility of future coal costs have been raised as a matter of concern by federal agencies as well.
Moody's and Standard & Poor's have raised the issue of "cumulative risk" in their reports. Future carbon regulation alone creates a significant financial risk to coal as a future resource for electricity generation. However, as a pure financial play it is the combination of regulatory burdens and shifting market realities related to coal generation that requires a full explanation for investors.
The recent changes in the nation's fortunes related to its natural gas supply have placed the rising cost of coal into stark relief against its competition: wind, solar, natural gas and energy efficiency. Progress Energy's recent decision to close much of its existing coal fleet rests on its own cost-benefit analysis of these risks.
Comprehensive disclosure of information to bond investors is essential to smooth market functioning. This needs to include untidy facts like the federal government pulling out of financing coal plants, as well as disclosure of the cumulative costs from factoring the real cost of coal into the price of electricity, even if it shows that coal-plant investments are no longer competitive.
