Energy Equity and BCA

Energy Equity and BCA

(Continued from NESP Quarterly February 14, 2022) — We first posed the question “How do we account for energy equity in BCAs?” in our June 2021 newsletter. We’ve since further collaborated with organizations to evolve our conceptual framework for how and where energy equity fits within benefit-cost analysis. Below is a summary of this framework, which is a work in progress. With further input and refinement from key stakeholders, our aim is to develop compendium guidance to the NSPM this year.

“An equitable energy system is one where the economic, health, and social benefits of participation extend to all levels of society, regardless of ability, race, or socioeconomic status. Achieving energy equity requires intentionally designing systems, technology, procedures, and policies that lead to the fair and just distribution of benefits in the energy system.”

PNNL: Review of Energy Equity Metrics – Oct 2021

Affirming equity in all aspects of the energy system is key to building a just and clean energy system and is increasingly being identified as a key policy goal by legislatures around the country. Many PUCs, utilities and stakeholders are making strides in addressing energy equity by developing procedural metrics to ensure participation by target populations (e.g., marginalized communities) in program design, delivery and decision making, and setting goals to increase program participation and reduce energy burden for target populations. These efforts are critical to addressing key aspects of energy equity. However, more work is needed to explicitly measure the distributional impacts of DER programs i.e., will program benefits be distributed equitably across all customers, including target populations?

Benefit-cost analysis is used to measure the utility system, host customer, and societal costs[1] and benefits of a DER program or policy on average across the utility system, typically expressed as monetized impacts or benefit-cost ratios (BCR). BCA can incorporate some aspects of energy equity, primarily in cases where a program is designed, implemented and evaluated for a specific target population (e.g., limited income, an EJ community program, etc.). In these cases, both energy and non-energy benefits to host customers can be assessed, or in some cases alternative BC ratio thresholds can be used (e.g., < 1.0). Additionally, transgenerational equity can be captured by using low discount rates (e.g., 2-3%) to calculate the net present value of the impacts: where a greater value is placed on the impacts of DER investments in the long-term versus the short-term. But these aspects of BCA do not fully address the distribution of benefits and costs to target populations.

To address distributional impacts, we offer the conceptual framework in the figure below, where distributional equity analyses (DEA) are conducted alongside BCAs when evaluating programs and policies. This is in addition to, but separate from, addressing procedural and structural energy equity metrics. DEAs can help determine if program benefits will be distributed equitably to target populations, where metrics can include:

  • Rate (¢/kwh) and bill ($/month) impacts;
  • Participation rates (% eligible) in programs;
  • Energy burden (% of income spent on energy bills)
  • Impacts on health & safety, economic development (job-years), reliability (CEMI – Customers Experiencing Multiple Interruptions), resilience (customer outages, restoration time, etc.); and
  • Environmental /health and other impacts in specific locations / geographic areas.

NESP is still refining this framework, but we believe it will help provide jurisdictions with a path to explicitly measure and include distributional equity in decision making. Questions and challenges remain regarding the framework’s use, including:

  • Is distributional equity analysis a part of a broader BCA, or is it a distinct analysis?
  • How should distributional equity analysis results be presented? How should stakeholders use distributional equity analysis results in decision making?
  • What customer data must utilities collect in order to conduct a distributional equity analysis, and what challenges are there to collecting this data?

As NESP drafts guidance on this topic, we will continue to collaborate with and seek input from our peers in this space, including key work from the following organizations/companies:

In the meantime, we welcome your thoughts and feedback on this conceptual framework and invite your comments at nspm@nationalenergyscreeningproject.org

What’s in Store for 2022?

What’s in Store for 2022?

(Continued from NESP Quarterly February 14, 2022) — This year is off to a busy start! New publications are coming soon, we are providing technical assistance to states applying the NSPM, and we’re gearing up to expand the NSPM to address key topics including guidance on accounting for energy equity.

Companion Resources to the NSPM

In our October NESP Quarterly (pg. 6), we shared a flavor of two forthcoming NESP publications:

Methods Tools Resources handbook cover
  • Methods, Tools & Resources: A Handbook for Quantifying Distributed Energy Resource Impacts for Benefit-Cost Analysis; and
  • Benefit-Cost Analysis Case Studies – Examples of Distributed Energy Resource Use Cases

While we hoped to publish by now, they are expected in March 2022. These companion documents to the NSPM for DERs will further help guide jurisdictions in their BCA efforts.

The 200+ page Methods, Tools & Resources (a.k.a. “MTR Handbook”) provides a wealth of technical information on how to quantify the full range of utility system and non-utility system impacts of DER investments, with links to resources and tools. Once a jurisdiction applies the NSPM BCA framework to develop or update its primary cost-effectiveness test, the MTR Handbook can guide decisions on what methods to use to quantify the relevant impacts in the jurisdiction’s BCA test.

The BCA Case Studies take the theoretical to application. Informed by real-world use cases but generalized into illustrative examples, they demonstrate applying the NSPM to specific DER technologies and programs of growing interest: residential EV managed charging, commercial combined solar and storage dispatch, and residential grid-interactive and efficient building (GEB) retrofits. The three case studies highlight different jurisdiction-specific tests (JSTs) based on policy objectives for three hypothetical jurisdictions. Each illustrates key BCA considerations for either single or multi-DER use cases and demonstrates different approaches to account for impacts when certain data may be unavailable.

State Technical Assistance in Applying the NSPM

We are providing technical assistance to commissions in applying the NSPM framework. Assistance is in the context of updating BCA practices for DER programs, procurement, and/or broader planning efforts. With support from U.S. DOE via Lawrence Berkeley National Laboratory, we will provide technical assistance throughout the year to select states, budget permitting. If your jurisdiction is interested in such services, please contact NSPM@nationalenergyscreeningproject.org.

Expanding NSPM Guidance

Based on 2021 experience with NSPM application, we are prioritizing areas where additional guidance is warranted to help jurisdictions with BCA practices, such as:

  • Accounting for energy equity in the context of benefit-cost analyses (BCAs), including developing the concept of a separate but complementary distributional equity analysis.
  • Applying the principles and concepts of the NSPM to a range of regulatory settings, including distribution system planning, integrated resource planning, grid modernization, time-of-use rates, and more.
  • Use of discount rates in BCAs, including whether and how to use different rates for different BCA tests and across BCA assumptions (e.g., for the social cost of carbon versus other costs or benefits), and use of nominal vs real rates, etc.
  • How to treat offsetting impacts (i.e., transfer payments), especially in context of tax incentives.
  • Treatment of other fuel impacts to consider in BCA, which is particularly relevant and important for electrification measures, programs and strategies.

These updates/expansions to the NSPM are slated for later 2022.
