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).
The increase of NOx, SO2, mercury and CO2 will decrease electricity prices.
mnli hypothesis: The increase of NOx, SO2, mercury and CO2 will decrease electricity prices. 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).
