Premise: However, in the analysis responding to the Jeffords/Lieberman request that had NOx, SO2, mercury and CO2 reduction levels similar to S. 556, we found significant  approximately a 20-30 percent decline of coal generation and a 30-50 percent increase in electricity prices compared to the reference case (depending on assumptions of energy technology penetration).

Hypothesis: The increase of NOx, SO2, mercury and CO2 will decrease electricity prices.
Relation: neutral
