Missing Methane GHG Adder is added in, along with impact of the EUL study. Used 20 yr GWP for Methane , IPCC assumption of 87 https://www.iea.org/reports/methane-tracker-2021/methane-and-climate-change

Missing Methane GHG Adder is added in, along with impact of the EUL study. Used 100 yr GWP for Methane but with the IPCC assumption of 36GWP (rather than 25)

Missing Methane GHG Adder is added in, along with impact of the EUL study. Used 100 yr GWP for Methane

This analysis assumes the 20yr GWP for Methane (current ED practice is to use 100yr GWP)

This is a corrected analysis with where the extra GHG Adder impact is only inclusive of Methane Leakage from the pipes. This analysis is looks at Residential Fuel-Sub Measures and the extra GHG Adder includes upstream leakage in the pipelines and behind-the -meter leakage.

If EE factored Participant Utility Bill Savings Benefits or the Costs of Infrastructure upgrades, how would this impact the TRC of Fuel-Sub projects? To explore this question, Calculate Gas Benefits with Utility Bill Savings, and Total Costs with Infrastructure Costs of the Fuel-Sub Measures claimed in PG&E’s 2023 Plug Load and Appliance, and Upstream HVAC Programs in Single Family Homes.
