NR 432.04(2)(2) Electric reliability. The department may allocate CAIR NOx allowances from the compliance supplement pool to any CAIR NOx unit for which the unit’s CAIR designated representative demonstrates that compliance with the CAIR NOx allocation under s. NR 432.03, Table 1 for calendar year 2009 would create an undue risk to the reliability of electricity supply during 2009. The CAIR designated representative of the unit may request the allocation of CAIR NOx allowances from the compliance supplement pool in order to avoid an undue risk to the reliability of electricity supply during 2009 in accordance with the following requirements: NR 432.04(2)(a)(a) The CAIR designated representative of the CAIR NOx unit shall submit to the department by July 31, 2009 a request for allocation of an amount of CAIR NOx allowances from the compliance supplement pool not exceeding the minimum amount of CAIR NOx allowances necessary to remove the undue risk to the reliability of electricity supply. NR 432.04(2)(b)(b) In the request under par. (a), the CAIR designated representative of the CAIR NOx unit shall demonstrate that, in the absence of an allocation to the unit in the amount of CAIR NOx allowances requested, the unit’s compliance with CAIR NOx allocation under s. NR 432.03, Table 1 for calendar year 2009 would create an undue risk to the reliability of electricity supply during that year. This demonstration shall include a showing by the unit’s CAIR designated representative that it would not be feasible to do both of the following: NR 432.04(2)(b)1.1. Obtain a sufficient amount of electricity from other electricity generation facilities for compliance with the CAIR NOx allocations under s. NR 432.03, Table 1 to prevent the undue risk.

Register July 2007 No. 619, eff. 8-1-07. NR 432.05NR 432.05 CAIR NOx ozone season allowance allocation. The department shall use the procedures in this section for calculating and allocating CAIR NOx ozone season allowances for CAIR NOx units and CAIR renewable units. NR 432.05(1)(a)(a) Calculating baseline energy output. The department shall calculate the baseline energy output of each CAIR NOx unit and each CAIR renewable unit, in MWh according to the following equations as appropriate: NR 432.05(1)(a)1.1. For a CAIR NOx unit that is a cogeneration unit and that has operated for 5 or more consecutive calendar years, by using one of the following equations: NR 432.05(1)(a)1.a.a. Use equation 1a if the unit is the only unit serving a generator or, if more than one unit serves the same generator and unit-level data for equation 9a is available for all units: where:
B is the unit baseline energy output made available by the cogeneration unit in MWh

NR 432.05(1)(a)1.b.b. Use equation 9b if more than one unit serves the same generator and unit-level data for equation 9a is not available for all units: where:
Bi is the baseline energy output made available by cogeneration unit i in MWh
GEGen is the average of the 3 highest annual amounts of the ozone season gross electric output in MWh for the generator served over the 5-year period identified in par. (b)
TET is the average of the 3 highest annual amounts of ozone season useful thermal energy in mmBtu for the generator served over the 5-year period defined in par. (b)

NR 432.05(1)(a)2.2. For a CAIR NOx unit that is not a cogeneration unit and that has operated for 5 or more consecutive calendar years and for a CAIR renewable unit that has operated for 5 or more consecutive calendar years, by using one of the following equations as appropriate: NR 432.05(1)(a)2.a.a. Use equation 10a if the unit is the only unit serving a generator or, if more than one unit serves the same generator and unit-level data for equation 10a is available for all units: where:
B is the unit baseline energy output made available by the CAIR NOx unit or the CAIR renewable unit in MWh
GEavg is the average of the 3 highest annual amounts of the unit’s ozone season gross electric output in MWh over the 5-year period identified in par. (b)
NR 432.05(1)(a)2.b.b. Use equation 10b if more than one unit serves the same generator and unit-level data for equation 10a is not available for all units: where:

NR 432.05(1)(b)(b) Periodic updates of baseline energy output for units with more than 5 years operating data. The department shall use the procedures in this paragraph for calculating the unit baseline energy output for each CAIR NOx unit or CAIR renewable unit which has more than 5 years of operating data. NR 432.05(1)(b)1.1. In 2007, the department shall calculate the baseline energy output for each CAIR NOx unit for 2009 to 2014 allowances using data for the ozone seasons 2000 to 2004. NR 432.05(1)(b)2.2. On or before May 1, 2011, and on or before May 1 of every fifth year thereafter, the department shall calculate the baseline energy output for each CAIR NOx unit and each CAIR renewable unit for the next 5-year allocation period using data from the 5 ozone season period beginning 9 years before the first year of the allocation period and ending 5 years before the first year of the allocation period. NR 432.05 NoteNote: For example in 2021, unit baseline energy output for the calculation of allocation for 2025 to 2029 allowances will be calculated using ozone season data from the years 2016 to 2020. In 2026, unit baseline energy output for the calculation of the allocation for 2030 to 2034 will be calculated using ozone season data from 2021 to 2025.
NR 432.05(1)(c)(c) Baseline energy output for new units and units achieving 5 years of operating data for the first time. The department shall use the procedures in this paragraph for calculating the unit baseline energy output for each CAIR NOx unit or CAIR renewable unit which have only 5 years of operating data. NR 432.05(1)(c)1.1. On or before May 1, 2011, the department shall calculate the baseline energy output for each CAIR NOx unit and each CAIR renewable unit that commences operation on or after January 1, 2001 and that has operating data for the years 2006 to 2010 for 2015 to 2019 allowances using data for ozone seasons 2006 to 2010. NR 432.05(1)(c)2.2. On or before May 1, 2012, and on or before May 1 of every year thereafter, the department shall calculate the unit baseline energy output for each CAIR NOx unit and each CAIR renewable unit that has been operating for its first 5 consecutive years, using the first 5 ozone seasons of operating data. Once the unit’s baseline energy output has been established, the CAIR NOx unit or CAIR renewable unit’s baseline energy output shall be updated according to par. (b). NR 432.05 NoteNote: Starting in 2011, and every year thereafter, new units that commence operation on or after January 1, 2001 will have their unit baseline energy output calculated once the unit has 5 consecutive years of operating data. The 5 years of data do not have to be full years of data. Once the unit has 5 or more years of operating data, this unit is then incorporated into the state baselines calculated in s. NR 432.03 (1m) and receives allocations from the main allocation pool under s. NR 432.03 (2). These new units are incorporated into the main allocation pool on a yearly basis. NR 432.05(1)(d)(d) Baseline energy output for retired units. If a unit is retired in any year, the department shall calculate the baseline energy output according to par. (b). If a unit only operates a portion of the year, the data for that portion shall constitute the unit’s data for that year. NR 432.05 NoteNote: The following is an example of how a retired unit’s baseline energy output is calculated. A unit is retired in 2011. In 2011, unit baselines are updated using 2006 to 2010 ozone season data that will be used to calculate allocations for 2015 to 2019. For 2015 to 2019 allocations, the retired unit would receive all allowances based upon its unit baseline for 2006 to 2010 ozone season operating data even though it is no longer operating. In 2016, the next unit baseline updating year, the baseline for the unit would be determined using the most recent 5 years of ozone season data, 2011 to 2015. The 2016 updated baseline would be used to determine allocations for 2020 to 2025. If the unit had some operating data in 2011, it would receive minimal allowances in 2020 to 2025 based on the amount of electrical generation in the ozone season in 2011. The next unit update would occur in 2021 and would use 2015 to 2019 ozone season operating data. Since the unit would have no operating data for this time period it would no longer receive allocations. Under this procedure a unit that is retired in 2011 could receive allowances until 2025.
