  1. Standardization Team Recommendations on Treatment of Homes with IOU Space Heating and Non-IOU Combustion Appliances, filed March 12, 2004 Presented to Low Income Oversight Board Fresno, CA May 2, 2006

  2. Background • Standardization of natural gas appliance CO testing procedures for the LIEE program raised several questions: • Should non-IOU fuel combustion appliances be tested for CO? • Should these homes be eligible for infiltration-reduction measures? • Homes that receive IOU-space heating are eligible for infiltration measures under the LIEE program. • Homes receiving infiltration-reduction measures must receive CO testing. • D.03-11-020, OP.12 directed the Standardization Team to study these issues and make a recommendation to the Commission regarding LIEE treatment of these homes. • Joint Utility Report on the Treatment of LIEE Homes using IOU Space Heat that also have non-IOU Combustion Fuels was filed March 12, 2004. • LIOB Presentation April 27, 2004

  3. Current IOU CO Testing Practices • PG&E: Conducts two types of CO testing procedures in LIEE: • A pre-CO test in PG&E-spaced heated homes with non-IOU combustion fuel appliances, and the post-NGAT in all other homes. • Prior to the adopted NGAT Protocols, PG&E’s CO testing procedures included tests of non-IOU combustion fuel appliances (such as propane water heaters) to ascertain the safety and feasibility of installing infiltration measures in LIEE participant homes. • The NGAT protocol adopted in D.03-11-020 does not allow non-IOU fueled combustion appliance testing. • D.03-11-020 directed PG&E to continue its previous practices in PG&E-space heated homes and homes that also have non-PG&E supplied combustion appliances until the Commission rules on the Standardization Team’s recommendations. • The Commission has not yet ruled on this issue and PG&E continues to provide combustion appliance testing on these non-IOU combustion fueled appliances, as directed by D.03-11-020. • SDG&E and SCG: Conduct NGAT procedures only. • Do not perform CO tests on non-IOU fueled appliances. • SCE: Does not supply gas and does not conduct CO testing.

  4. Option 1 Restrict NGAT assessments to IOU natural gas appliances, but still install infiltration-reduction measures in homes with non-IOU combustion appliances Option 2 Conduct NGAT assessments for other combustion appliances (e.g., propane) prior to weatherization, and install infiltration reduction measures only in homes that pass the NGAT test Option 3 Conduct NGAT assessments for other combustion appliances (e.g., propane) prior to or after weatherization, and repair or replace these appliances if they fail the NGAT test. Option 4 Restrict NGAT assessments to IOU natural gas appliances, and deem infiltration reduction measures non-feasible for all homes using other combustion fuels. Options Considered for Eligible Homes with Non-IOU Combustion Fuels

  5. Standardization Team Recommendations • Option 4: Restrict NGAT assessments to IOU natural gas appliances, and deem infiltration reduction measures non-feasible for all homes using other combustion fuels • Refer homes for which infiltration reduction measures are deemed non-feasible for this reason to LIHEAP or (if relevant) utility providing natural gas • Request LIHEAP agencies and/or other natural gas utilities to report back to IOUs.

  6. Team Recommendations on Treatment of Homes with IOU Space Heating Fuel and Non-IOU Combustion Appliances • These homes should not be given infiltration-reduction measures under the LIEE Program. • Reiterated current policy in response to Commission’s instruction to “explore alternatives that would tailor the Team’s proposed policy to a more specific set of circumstances, depending upon the type and/or location of the non-IOU fueled appliance.” • Reaffirmed commitment to leveraging with other programs. • Emphasized the need for agreements with LIHEAP providers to be voluntary and to depend on specific circumstances. Left open what would be installed by LIHEAP providers. • Reiterated that, in cases where voluntary agreements cannot be made, the IOUs will continue to install all feasible non-infiltration-reduction measures, then refer customers to the local LIHEAP agency.
