Adjustable Savings Goals

The Adjustable Savings Goals policy can be found within Illinois Energy Efficiency Policy Manual Version 2.1 and is applicable for Illinois gas utilities (Ameren Illinois, Nicor Gas, Peoples Gas & North Shore Gas). Following Commission approval of the annual IL-TRM update, gas utilities complete draft adjustable savings goal templates for review by interested stakeholders. Final adjustable savings goal templates are filed with the Commission within 90 days following approval of the IL-TRM.

Adjustable Savings Goals Policy

See Section 6.2 of Policy Manual Version 2.1, Adjustable Savings Goals Beginning in 2022 (pages 22-23):

“Gas utility annual energy savings goals will be adjusted to align them with changes to IL-TRM values. The Energy Efficiency Measure participation levels identified in the approved Plan to derive the energy savings goals shall be fixed, solely for the purpose of the adjustable savings goal calculation, for the entirety of the Plan.

Gas utilities have the discretion at the time of Plan filings to propose adjustable savings goals with NTG collars as set forth below. Gas utility annual energy savings goals may be adjusted, as specifically provided below, if final deemed NTG Ratios determined under the NTG Policy defined in Section 7.2 fall outside the bounds of NTG collars approved by the Commission in Program Administrator Energy Efficiency Plan Dockets. NTG collars only apply to Energy Efficiency Measures, Program components and/or Programs subject to their own single NTG Ratio and that account for ten (10) percent or more of Portfolio Plan savings. NTG collars must be at least ten (10) percentage points, except for income qualified Measures, where the NTG collars are defined as plus-or-minus zero (0) percentage points.

For the purpose of calculating the adjusted savings goal, gas utilities will calculate the NTG Ratio as follows:

  • If the deemed NTG Ratio exceeds the collar cap, the adjusted NTG Ratio will equal the NTG Ratio included in the gas utility’s approved Energy Efficiency Plan, plus the difference between the deemed NTG Ratio and the collar cap, i.e.:
    • adjusted NTG Ratio = Plan NTG Ratio + (deemed NTG Ratio – cap NTG Ratio)
  • If the deemed NTG Ratio is less than the collar floor, the adjusted NTG Ratio will equal the NTG Ratio included in the gas utility’s approved Energy Efficiency Plan, less the difference between the collar floor NTG Ratio and the deemed NTG Ratio, i.e.:
    • adjusted NTG Ratio = Plan NTG Ratio – (floor NTG Ratio – deemed NTG Ratio)
  • If the deemed NTG Ratio is between the collar cap and the collar floor, the adjusted NTG Ratio will equal the NTG Ratio included in the gas utility’s approved Energy Efficiency Plan.

In addition, gas utility annual energy savings goals will be adjusted for the entire Plan period, prior to the start of the first Plan Year of an approved Plan, so that they are aligned with changes to IL-TRM values and the most recent Evaluator’s recommended Net-to-Gross (NTG) Ratio values available. Nothing in this policy shall be interpreted to alter the Program Administrator’s duty to shift budgets between Programs in response to changing market conditions, new information or insights into Program Cost-Effectiveness and/or other factors in order to better enable achievement of Cost-Effective energy savings, better serve Customers (including income qualified Customers) and/or address other approved Portfolio objectives included in this Policy Manual.

Within ninety (90) days after Commission approval of the annual IL-TRM values, each gas utility will file adjusted energy savings goals reflecting updated IL-TRM values, as well as final NTG Ratio values falling outside the bounds of approved NTG collars, applicable to the Program Year commencing January 1. In advance of such filing, the independent Evaluators will verify that the adjustments to the energy savings goals have been performed accurately.

Gas utility Program Administrators shall send draft adjustable savings goals spreadsheets to the SAG Facilitator on an annual basis. Draft adjustable savings goals will be discussed with interested SAG participants before finalizing, as needed. The SAG Facilitator will post final adjustable savings goals spreadsheets to the SAG website.

The provisions in Section 6.3 impacting the adjustment of gas utility annual energy savings goals shall sunset for a utility upon the effective date of a Commission-approved tariff that permits that utility to earn performance incentive payments impacting the rates customers pay. The potential applicability of an adjustable savings goals policy to a utility earning performance incentives may be determined by the Commission in a utility’s Energy Efficiency Plan docket, updates to the Policy Manual, or other Commission proceedings.”
