Fitch says the decision will severely constrain the construction of future coal-fired
The effects are also expected to further strain the

Moreover, Fitch says it foresees a continued reduction in
the use of coal as a fuel and an increase in the use of natural
As such, fuel price dynamics have already begun a large

from coal than natural
gas-fired units. In April 2012, they contributed nearly the
Other power resources, including nuclear, may also be given
greater consideration going forward.
Future construction of coal-fired plants is
unlikely given these rules and a myriad of others due this year
