The electric generating industry has been besieged with piecemeal pollutant-by-pollutant regulation.
A piecemeal pollutant-by-pollutant approach to emissions reductions is costly and inefficient.
Power producers must make expensive control decisions for some pollutants without knowing the
requirements that will apply to other pollutants – or even to the same pollutants in the near future.
In contrast, an multi-pollutant approach would allow electricity generators to optimize their
pollution control decisions. A multi-pollutant strategy with firm caps on emissions will create
a stable environment for capital investment by providing relatively long-term certainty about the
industry’s future emission reduction obligations. With a clear understanding of future compliance
obligations, companies can then target investments in new and existing electric generation capacity to
reduce emissions and enhance electric system reliability.
