Total SF6 Imported Inside Equipment (Mt CO2e) = 153,323Summary Data (see notes and assumptions below)Reminder: The data below is based entirely on numbers provided by an industry representative. Although the representative isconsidered to be familiar with industry statistics, the numbers should still be used with caution. Because GIS uses such a largeamount of SF6 per unit, a revision of either the number of imported units or the average nominal charge would significantlychange our aggregate estimates.Total circuit breakers between 72 and 345 kV and GIS units, both imported with or without nominal charge1000Total number of CBs imported with a nominal charge200Total number of GIS imported with a nominal charge67Average nameplate capacity of CBs (lbs of SF6)70.71532Average nameplate capacity of GIS (lbs of SF6)12856Average nominal charge as percent of total nameplate capacity of equipment20%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 substations (GIS). Equipmentais 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 by smaller domestic manufacS&C and G&W) with no major manufacturing capacity oversees. However, the Yaskawa Electric Company is a Japanese company that markets medium voltage equipment in the U.S. buhave any U.S. manufacturing capacity, which makes them a potential importer. Because it is unclear whether they are actually importing gas-insulated equipment, how many units theywimporting, and how much gas the equipment would contain (would be relatively small compared to high-voltage equipment), we have not included Yaskawa in our analysis. But please nomight be imports of medium voltage equipment containing a relatively small amount of SF6 that we are not covering. (Bolin, 06/24/2008) and (Meyer, 04/29/2008).2.We assume that equipment is imported by a total of eight manufacturers: ABB, Areva, HVB AE, Mitsubishi, Siemens, Fuji, Hyundai, and Meidensha (Bolin, 05/15/2008).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):1000Fraction of 1000 that is composed of CBs:2/3Fraction of 1000 that is composed of GIS:1/3Of 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 that200 circuit breakerswith a nominal charge are imported annually (all are between 72 and 345 kV).5.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 approximately71 poundsof SF6.6.Given the approximations provided by Phil Bolin, we estimate that approximately67 GISwith 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 animported GIS unit is 12,856 lbs.of SF6 (Researc8.We assume that the average nominal charge of gas-insulated equipment is20%of the equipment's nameplate capacity (Meyer, 04/29/2008 and Bolin, 05/15/2008).9.Only GIS is exportedabove 345 kVcturers (e.g.ut does notwould beote that therech performed by Paul Stewart of ICF).PU RigidSandwhichPanelsCommercialRefrigerationPU Rigid(DomesticRefrigeration)XPS SheetXPS Boardstocklbs/cu ftkg/cu ftmt/cu ft0.230.10432630.00010430.2050.09298650.00009300.210.09525440.00009530.190.08618260.00008620.210.09525440.0000953email from Bob Russell to Marian Van Pelt 6/13/08Felxible PU Foam: Slabstock Foam, Moulded Foam: HC, but some HFC-134a: 0.19-0.23 lbs./cu.ft.>> PU and PIR Rigid: Boardstock>>> PU Rigid: Domestic Refrigerator and Freezer Insulation: HFC-245fa / HFC-134a 0.20-0.22 lbs./cu.ft>>> PU Rigid: Spray Foam: HFC-245fa, 0.20 lbs / cu.ft.>>> PU Rigid: Other: Slabstock Foam>>> XPS: Sheet Foam: HC, but some HFC-152a, 0.18 - 0.20 lbs./cu.ft.>>> XPS: Boardstock Foam: HFC-134a, 0.20-0.22 lbs./cu.ft>>> Felxible PU Foam: Integral Skin Foam>>> Polyolefin Foam>>> Phenolic Foam>>> PU Rigid: One Component Foam>>> Commercial Refrigeration Foam: HFC-245fa, some HFC-134a 0.19-0.22> lbs./cu.ft>>> PU Rigid: Sandwich Panels: Continuous and Discontinuous: some HFC-134a> use, 0.22-0.24 lbs./cu.ftConversions0.4535925kg/lb1000kg/mt
