  • Subcommittee objectives

  • Objectives for today

  • Genesis of the problem

  • Regional Act and Regulatory requirements

  • Abt Associates presentation

  • Discussion

  • Next steps

  • Adjourn

Subcommittee objectives
Subcommittee Objectives

  • Exploring alternative options to quantify the net health impacts of displacing wood heat with electric powered heat.

    • Different options available to model health impacts of particulate emissions on air quality.

    • Granularity of results one can expect from this modeling exercise.

    • Inherent assumptions and uncertainties associated with such modeling

    • Data required to conduct this analysis.

Objectives for today
Objectives for Today

  • Discussion to provide direction for staff to draft a Scope of Work

    • Make recommendations to RTF on options and methods.

    • Understand how results from this exercise will be applied

    • Direction will be gathered from discussion in the subcommittee meeting.

Genesis of the problem
Genesis of the Problem

  • Ductless Heat Pumps (DHP) replace wood heat in some residential homes.

    • This reduces wood smoke emission

      … but this also adds load to the grid

    • Preliminary analysis showed the health benefits from avoided wood smoke to be significant, larger than electric savings

    • Other EE measures also reduce wood heat (e.g. weatherization)

Regional act context section 3 4 cost effectiveness
Regional Act Context: Section 3(4) Cost-effectiveness

“System cost” is defined to mean “an estimate of all direct costs of a measure or resource over its effective life,” including, “among other factors”:

  • cost of distribution and transmission to the consumer, if applicable

  • waste disposal costs

  • end-of-cycle costs

  • fuel costs (including projected increases)

  • such quantifiable environmental costs and benefits as the Administrator determines, on the basis of a methodology developed by the Council as part of the plan are directly attributable to such measure or resource

Rtf guidelines
RTF Guidelines

  • RTF Guidelines describe analysis of costs & benefits

  • Guideline section 4.5 identify “other non-energy” cost & benefits

    • General guideline: “included in a measure cost analysis if it can be sufficiently demonstrated to the RTF that the impacts are significant and monetizable.”

Wa public utilities regulation
WA Public Utilities Regulation

  • RCW 80.52.030(8): “… the definition of cost-effective, which applies to conservation and other resources, relies on system costs that explicitly includes quantifiable environmental costs and benefits.”

    • System Costs include quantifiable environmental costs and benefits.

    • The 1980 Northwest Power Act also includes quantifiable environmental costs and benefits in the “system cost” to be included in cost effectiveness calculations.

  • Staff has not had a chance to understand regulatory requirements of OR, MO, ID

Abt presentation
ABT Presentation

  • ABT presentation will contain three options for analysis:

    • Option 1: Screening Level Analysis (Basic Detail)

      • 3 months; $20,000 - $40,000 (Abt estimate)

    • Option 2: EPA RIA- Style Analysis for CAPs (Medium Detail)

      • 6 – 8 months; $60,000 - $200,000 (Abt estimate)

    • Option 3: EPA RIA- Style Analysis for CAPs and HAPs (High Detail)

      • Cost and duration will be more than Option 2


  • Scope of this analysis for electric utilities

  • Feasibility of presented options

    • Potential bias inherent in each option

    • Importance of granularity

  • Consider impacts beyond health?

  • Other ideas/ considerations?
