Summary Data (see notes and assumptions below) 

Reminder: The data below is based entirely on numbers provided by an industry representative. Although the representative is considered to be familiar with industry statistics, the numbers should still be used with caution. Because GIS uses such a large amount of SF6 per unit, a revision of either the number of imported units or the average nominal charge would significantly change our aggregate estimates. Total circuit breakers between 72 and 345 kV and GIS units, both imported with or without nominal charge 1000 Total number of CBs imported with a nominal charge 200 Total number of GIS imported with a nominal charge 67 Average nameplate capacity of CBs (lbs of SF6) 70.71532 Average nameplate capacity of GIS (lbs of SF6) 12856 Average nominal charge as percent of total nameplate capacity of equipment 20% Notes/Assumptions for Gas-Insulated Equipment Containing SF6: 1. We have assumed that most SF6 imported into the United States inside equipment is either in circuit breakers between 72 and 345 kV or gas-insulated suis too large to ship assembled with a nominal charge. Equipment below 72 kV sometimes contains SF6, but we assume that most of this equipment is made S&C and G&W) with no major manufacturing capacity oversees. However, the Yaskawa Electric Company is a Japanese company that markets medium volhave any U.S. manufacturing capacity, which makes them a potential importer. Because it is unclear whether they are actually importing gas-insulated equipimporting, and how much gas the equipment would contain (would be relatively small compared to high-voltage equipment), we have not included Yaskawa imight be imports of medium voltage equipment containing a relatively small amount of SF6 that we are not covering. (Bolin, 06/24/2008) and (Meyer, 04/29/22. We assume that equipment is imported by a total of eight manufacturers: ABB, Areva, HVB AE, Mitsubishi, Siemens, Fuji, Hyundai, and Meidensha (Bolin, 3. Phil Bolin provided us with the following estimates of equipment imports (Bolin, 06/24/2008): Total number of units imported (CBs and GIS combined, this number roughly confirmed by Richard York of ABB, 06/24/2008): 

1000

 Fraction of 1000 that is composed of CBs: 

2/3

 Fraction of 1000 that is composed of GIS: 

1/3

 Of the CBs imported, number that have a nominal charge: 

30%

 Of the GIS imported, number that have a nominal charge: 

20%
 

4. Given the approximations provided by Phil Bolin, we estimate that 200 circuit breakers with a nominal charge are imported annually (all are between 72 a5. By analyzing the SF6 field study survey, we have assumed that the average nameplate capacity of a circuit breaker between 72 and 345 kV is approximate
6. Given the approximations provided by Phil Bolin, we estimate that approximately 67 GIS with a nominal charge are imported annually. 

7. By analyzing the GIS units used by a large SF6 Emission Reduction Partner, we assume that the average nameplate capacity of an imported GIS unit is 

8. We assume that the average nominal charge of gas-insulated equipment is 20% of the equipment's nameplate capacity (Meyer, 04/29/2008 and Bolin, 05/
