New Measure Table Fields Added

FuelID

Addition of an FuelID field in the Measure table. Field is placed after MeasImpactType in the table column order. References CEDARS value list: https://cedars.cpuc.ca.gov/cet_ui/spec/fuelid/

The CET input file data specification now includes a new data field called “FuelID” that the CET will use, beginning in 2026, to identify fuel substitution measures to correctly apply supply costs in the cost effectiveness calculations.

For PY 2025 CET runs, users must include the field in CET input files, or the system will generate an error message; however, the field may be left blank until implementation begins in 2026. The CET will continue to reference the Measure Impact Type field to identify fuel substitution measures pending future updates to a VEA Decision.

UnitTaxCredits
Addition of an UnitTaxCredits field in the Measure table. Field is placed after MiscBensDesc in the table column order.

Users may include in this field Inflation Recovery Act tax incentives for energy to the cost calculation to capture the additional benefits of measures eligible for IRA tax credits.

The CET will sum UnitTaxCredits values with other benefits in the TRC calculation to reflect the way IRA credits have factored into potential and goals research. This new field is required for the data input specification but may be left blank.

Given the uncertainty of the IRA credits in the future, program implementers should work with their program administrator to determine appropriate values to include in this new field.

The UnitTaxCredits fields included in the output are:

• TaxCredits

• TaxCreditsGross

Refinement of Measure RUL_Yrs Validation Rules

In the CET validation rules, NMEC MeasImpactTypes are exempted from the rule that requires advanced replacement (MeasAppType = “AR”) measures to have a remining useful life value (RUL_Yrs) greater than zero.

In 2020 the DEER database MeasImpactTypes for NMEC were:

• Cust-NMEC-Pop

• Cust-NMEC-Site

Two years later the 2022 DEER database added two new NMEC MeasImpactTypes for fuel substitution measures:

• Cust-NMEC-Pop-FuelSub

• Cust-NMEC-Site-FuelSub

The existing validation rule was written before the fuel substitution options were added in 2022 and only exempts measures where MeasImpactType does not equal “Cust-NMEC-Pop” or “Cust-NMEC-Site”. Therefore, fuel substitution measures have not been exempted from this rule when they were supposed to be exempted.

Existing Rule:

Measure RUL_Yrs greater than 0 all Measure MeasAppType equals 'AR' Measure MeasImpactType not in ['Cust-NMEC-Pop', 'Cust-NMEC-Site']

Updated Rule:

Measure RUL_Yrs greater than 0 all Measure MeasAppType equals 'AR' Measure MeasImpactType not in ['Cust-NMEC-Pop','Cust-NMEC-Pop-FuelSub','Cust-NMEC-Site', 'Cust-NMEC-Site-FuelSub']
