The Social Cost of Carbon
Options for Applying a Metric in Flux
Many states and other jurisdictions are grappling with how to value greenhouse gas emission reductions and trying to understand the rapidly developing climate economics and science involved in this task. Frequently, state governments and other jurisdictions value greenhouse gas emissions in policymaking using a tool known as the social cost of carbon.
While applying the social cost of carbon is conceptually simple, the appropriate value to place on the metric is in flux. In late 2022, the federal government released new, updated values of the social cost of carbon in draft form which, for now, remain unfinalized. So what estimates of the social cost of carbon should states and other entities use during this transition period? This policy brief explores the available options.

Administrative Severability
A Tool Federal Agencies Can Use to Address Legal Uncertainty
Several recent developments in administrative law—namely the Supreme Court’s embrace of the major questions doctrine and decision to hear a case asking it to overrule or clarify Chevron deference—have left federal agencies uncertain about how regulations will fare in litigation. Agencies adapting to this uncertainty may want to pay closer attention to recent case law on administrative severability, which allows a court to sever the invalid portion of a rule while leaving the rest intact.

Comments to NJBPU on the Development of Natural Gas Utility Emission Reduction Plans
The New Jersey Board of Public Utilities is examining how to reduce greenhouse gas emissions from the state's natural gas sector in line with New Jersey's economy-wide emissions reduction goals. Policy Integrity submitted comments focused on the planning process and solutions needed to responsibly transition away from natural gas usage.

Wildfire, Power Shutoff, and Residential Energy Storage Adoption
Extreme weather poses a growing threat to electrical grid stability. On-site battery storage connected to solar power —known as a solar-plus-storage system—can buffer the impact. Despite its crucial benefits, the widespread adoption of this technology is hindered by its high costs. This study examines the impact of recent salient events—namely, preemptive power shutoffs to prevent wildfires, or Public Safety Power Shutoffs (PSPSs)—on residential solar-plus-storage adoption. I demonstrate that while communities at risk of wildfires lacked proactive investments before wildfire seasons, prolonged PSPSs increased solar-plus-storage adoption during the subsequent two months. This increased storage uptake can be attributed to heightened awareness of the need for backup power. Additionally, households’ choices between purchasing and leasing options were influenced by latent wildfire hazards and education levels. These findings highlight the role of risk awareness in promoting storage adoption and underscore the potential for using public information to enhance wildfire preparedness. -
Comments to PJM on the Resource Adequacy Critical Issue Fast Path
PJM Interconnection, which oversees wholesale electricity market operations for the mid-Atlantic region, is undergoing reforms to improve how the market values and prices generation capacity to ensure reliability. Policy Integrity submitted comments focused on PJM's proposed shift to a seasonal capacity market design and other proposed changes to reliability metrics.

Comments on the Consideration of Climate Benefits in Proposed Rule to Limit Methane Leakage from Gas Pipelines
In May, the Pipeline and Hazardous Materials Safety Administration released a draft regulation to prevent methane leaks from gas pipelines. The agency monetized the climate benefits of the regulation using the social cost of methane, finding that monetized benefits exceeded monetized costs by at least $340 million per year. In our comment letter, we support the agency for applying the social cost of greenhouse gases to estimate the climate benefits of the proposed rule. We also suggest that PHMSA apply additional analysis to each rule using draft updated climate-damage valuations that the Environmental Protection Agency released in November 2022.

Comments to NYSPSC on Its 2040 Zero-Emissions Electricity Goal
The New York State Public Service Commission recently issued an order seeking input on how to achieve the state's goal of a zero-emissions electricity system by 2040, as required by the Climate Leadership and Community Protection Act (CLCPA). Policy Integrity submitted comments focused on issues such as the relationship between the Commission’s 2040 zero-emissions goal and other elements of the CLCPA, the need for analytic frameworks that rely on best available science and economics, the circumstances under which hydrogen could qualify as a zero-emissions resource, and tracking benefits to disadvantaged communities.

Making Electricity Capacity Markets Resilient to Extreme Weather Events
The devastating 2021 blackout in Texas, among others, has highlighted the need to reform electricity markets to make them resilient to extreme weather events. In this paper, we review related efforts by system planners and operators within electricity market contexts, focusing on Europe and the United States, and we analyze possible reforms to electricity capacity markets. To account for extreme weather events, capacity requirements and markets, along with other regulatory measures throughout the electricity and fuel supply chains, should be modified. First, capacity requirements must be tailored to the specific severe weather failure modes applicable to a given power system to achieve policymakers' reliability and resiliency objectives: reducing the frequency, magnitude and duration of blackouts. Second, all capacity requirements should be cost-effective and integrated with other non-capacity resources and requirements, such as transmission, distribution and other infrastructure systems. Third, for a capacity market to produce the desired efficiency benefits, the product (capacity) must be well-defined and backed by sufficient credit and other policies to ensure providers have sufficient incentives to perform when called.

Amicus Brief in D.C. Circuit Opposing FERC Pipeline Approval
The Federal Energy Regulatory Commission (FERC) recently approved the construction of a new natural gas pipeline that would run through New Jersey and Pennsylvania. The gas capacity this expensive pipeline would provide, most of which will serve New Jersey markets, is unnecessary to meet the demand of New Jersey customers: the New Jersey Board of Public Utilities commissioned a study that demonstrates as much. We submitted an amicus brief in support of petitioners challenging this pipeline. In our brief, we explain that, in approving pipeline applications, FERC has abdicated its statutory responsibility to examine whether a pipeline is truly needed. Instead of determining whether a pipeline would serve the public interest, FERC defers to the assertions of profit-motivated pipeline developers and their customers. FERC's practice of approving needless pipelines is particularly concerning in light of how it regulates the development of electric transmission infrastructure, a related regulatory process. We argue that FERC should have placed greater weight on the rigorous economic study conducted by an expert state agency charged with ensuring safe and adequate gas supply for its residents.

Justifying Redistributive Regulations
Congress often relies on agencies to fill in the details of its transfer programs with regulations, such as those setting eligibility criteria for healthcare, housing, and nutritional assistance. This Article uses three recent rulemakings to illustrate how conventional cost-benefit analysis tends to obscure rather than illuminate agencies’ (often distributional) reasons for issuing such transfer regulations—generating unnecessary legal risk for the agencies and unnecessary confusion for the public. The Article then explains why recently proposed revisions to White House guidance on cost-benefit analysis—including the introduction of an analytic technique called income-based distributional weighting—will not fully resolve this problem. Finally, the Article recommends a new analytic framework for transfer regulations that recognizes the particular relevance of distributional concerns to their promulgation and the distinct challenges of assessing their net benefits.
