Avoided Cost of Capacity

Based on the Energy Information Administration's (EIA) Table 2, Cost and Performance Characteristics of New Central Station Electricity Generating Technologies, the base overnight cost of a combustion turbine-industrial frame is $626 per kilowatt (kW) in the Texas Reliability Entity or Electric Reliability Council of Texas (ERCOT) region. Because this amount is less than the $700 per kW threshold set by 16 Texas Administrative Code (TAC) §25.181(d)(2)(A)(ii), the avoided cost of capacity is $80 per kW-year for 2022. This information was filed in Project No. 38578, Item No. 46

Based on the Energy Information Administration's (EIA) Table 2, Cost and Performance Characteristics of New Central Station Electricity Generating Technologies, the base overnight cost of a combustion turbine-industrial frame is $626 per kilowatt (kW) in the Texas Reliability Entity or Electric Reliability Council of Texas (ERCOT) region. Because this amount is less than the $700 per kW threshold set by 16 Texas Administrative Code (TAC) §25.181(d)(2)(A)(ii), the avoided cost of capacity is $80 per kW-year for 2021. This information was filed in Project No. 38578, Item No. 28

Based on the Energy Information Administration's (EIA) Table 8.2, Cost and Performance Characteristics of New Central Station Electricity Generating Technologies, the base overnight cost of an advanced combustion turbine is $658 per kW. Since this amount is less than the $700 per kW threshold set forth in §25.181(d)(2)(A)(ii), the avoided cost of capacity will remain at $80 per kW for 2020.

Based on the Energy Information Administration's (EIA) Table 8.2, Cost and Performance Characteristics of New Central Station Electricity Generating Technologies, the base overnight cost of an advanced combustion turbine is $648 per kW. Since this amount is less than the $700 per kW threshold set forth in §25.181(d)(2)(A), the avoided cost of capacity will remain at $80 per kW for 2019.

Based on the Energy Information Administration's (EIA) Table 8.2, Cost and Performance Characteristics of New Central Station Electricity Generating Technologies, the base overnight cost of an advanced combustion turbine is $640 per kW. Since this amount is less than the $700 per kW threshold set forth in §25.181(d)(2)(A), the avoided cost of capacity will remain at $80 per kW for 2018.

Based on the Energy Information Administration's (EIA) Table 8.2, Cost and Performance Characteristics of New Central Station Electricity Generating Technologies, the base overnight cost of an advanced combustion turbine is $632 per kW. Since this amount is less than the $700 per kW threshold set forth in §25.181(d)(2)(A), the avoided cost of capacity will remain at $80 per kW for 2017.

Based on the Energy Information Administration's (EIA) Table 8.2, Cost and Performance Characteristics of New Central Station Electricity Generating Technologies, the base overnight cost of an advanced combustion turbine is $639 per kW. Since this amount is less than the $700 per kW threshold set forth in §25.181(d)(2)(A), the avoided cost of capacity will remain at $80 per kW for 2016.

Based on the Energy Information Administration's (EIA) Table 8.2, Cost and Performance Characteristics of New Central Station Electricity Generating Technologies, the base overnight cost of an advanced combustion turbine is $641 per kW. Since this amount is less than the $700 per kW threshold set forth in §25.181(d)(2)(A), the avoided cost of capacity will remain at $80 per kW for 2015.

Based on the Energy Information Administration's (EIA) Assumptions to the Annual Energy Outlook 2013, the base overnight cost of an advanced combustion turbine is $632 per kW. Since this amount is less than the $700 per kW threshold set forth in §25.181(d)(2)(A), the avoided cost of capacity will remain at $80 per kW for 2014.

Avoided Cost of Energy

Due to the unique circumstances caused by the February 2021 winter-weather event, the Commission found good cause to grant an exception to the requirements of 16 TAC §25.181(d)(3)(A) and set the avoided cost of energy at $85 per MWh which is equivalent to $.085/kWh for the 2022 program year (Commission Staff­s Petition for a Good Cause Exception to 16 Texas Administrative Code §25.181(D)(3)(A) and to Set the Avoided Cost of Energy Under § 25.1 81 (D)(3)(A) For 2022 Electric Utility Energy Efficiency Programs, Docket No. 52871, Order (May 12, 2022)). This information was filed in Project No. 38578, Item No. 54.

Using the methodology required in 16 TAC §25.181(d)(3)(A), ERCOT's calculation of the avoided cost of energy for 2021 is $101.61/MWh, which is equivalent to $0.10161/kWh. This information was filed in Project No. 38578, Item No. 27.
