Take the following as truth: 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).
Then the following statement: "The analysis of NOx, SO2, mercury and CO2 showed an increase in electricity prices." is true, false, or inconclusive?
Answer: True
