4.0 Results and Discussion NOx Emissions Report As shown in Table 4-1, the technical potential for additional CHP systems in HGB is large. In the commercial sector, potential exists today to develop CHP systems at about 2,944 facilities, which could amount to between 274 to 1,317 MW of electrical capacity. In the industrial sector, an estimated 946 additional CHP projects are technically possible, which could generate electrical capacity in excess of about 1,300 MW. In total, an estimated 1,600 – 2,600 MW of CHP capacity is possible at nearly 3,900 sites. Table 4-1: CHP Potential in HGB Sector Number of Facilities Capacity (MW) Commercial 2,944 274 – 1,317 Industrial 946 1,298 Total 3,890 1,572 - 2,615 Note: Electrical capacity range for commercial CHP depends upon Case 1 or Case 3 operation. Widespread CHP implementation of the magnitude suggested in Table 4-2 would likely produce a dramatic overall reduction in NOx emissions. Conservative estimates put the savings at between 2.9 to 9.4 tons per day from the commercial sector and about 10.0 tons per day from the industrial sector. Taken together, the total potential NOx impact from commercial and industrial CHP implementation is estimated to be between 12.9 and 19.4 tons per day, depending on operating strategy adopted in the commercial sector. However, because the majority of CHP systems implemented in the commercial sector are anticipated to use small systems using an Optimal Thermal Utilization (Case 3) strategy, total NOx savings achievable in the commercial sector are most likely to be in the range of 3 to 5 tons per day. Consequently, the total potential for NOx savings from widespread adoption of CHP in HGB is estimated to be in the rage of 13 – 15 tons per day. Potential NOx savings during the peak ozone season are expected to amount to between 17-21 tons per day. By 2020, economic and population growth in HGB is anticipated to create additional CHP opportunities across the region, which could result in even greater NOx reductions.
