A Community Assessment of Health Impacts from the Pittsfield Generating Facility on Local Communities

Client: Massachusetts Clean Peak Coalition

Authors: Jordan Burt, Elisabeth Seliga, Tanya Stasio, PhD, Lila McNamee, and Liz Stanton, PhD

February 2025

On behalf of the Massachusetts Clean Peak Coalition Researcher Jordan Burt, Assistant Researcher Elisabeth Seliga, Researcher Tanya Stasio, PhD, Research Assistant Lila McNamee, and Principal Economist Liz Stanton, PhD, prepared a report that summarizes the negative health impacts of fossil fuel-fired emissions on communities living near the Pittsfield Generating Facility. The report identifies three key takeaways:

1. As long as the Pittsfield Generating Facility is in operation, it has the potential to produce much higher greenhouse gas emissions and co-pollutants in any given year.

2. EJ and other vulnerable communities live in close proximity to the Pittsfield Generating Facility, increasing vulnerability to adverse health outcomes.

3. Replacing the fossil fuel-fired plant with clean energy resources can reduce emissions in the area.

December 2024

On behalf of the Berkshire Environmental Action Team, Researcher Jordan Burt, Assistant Researcher Elisabeth Seliga, Researcher Tanya Stasio, PhD, Research Assistant Lila McNamee, and Principal Economist Liz Stanton, PhD, prepared a report that reviews case studies of fossil-fuel plant conversions to clean energy resources across the country and discusses the replacement of existing peaker plants in Massachusetts to achieve statewide climate goals. The report identifies three key takeaways for the Commonwealth:

1.     Fossil-fuel sites can be desirable locations for clean energy siting

2.     Reducing reliance on fossil-fuel generation can help lessen the burden of environmental and health impacts on already overburdened communities

3.     Fossil-fuel plant conversions are a tool that can be used to achieve state and local greenhouse gas emission limits.

Illinois Adult Use Cannabis Industry Disparity Study

Client: Illinois Cannabis Regulation Oversight Office

Authors: Elizabeth A. Stanton, PhD, Bryndis Woods, PhD, Tanya Stasio, PhD, Jordan Burt, Deja Garraway, Nayantara Biswas, and Alannah Shute

July 2024

On behalf of the Illinois Cannabis Regulation Oversight Office, AEC assisted the Nerevu Group, LLC in preparing a disparity study to evaluate and assess existing discrimination within the State of Illinois cannabis industry. In particular, AEC staff reviewed public and private data sources to provide utilization, availability, and disparity analyses for the Illinois economy and the Illinois cannabis industry. AEC finds evidence of significant disparities in Illinois business ownership and wages across race/ethnicity and gender. Specifically, AEC finds that, compared to White men, racial and/or ethnic minorities and women are less likely to be business owners and have less access to capital through either hourly wages or bank loans.

To cultivate a more inclusive and equitable industry, Nerevu Group, LLC recommends broadening availability of financing for cannabis businesses, improved data management, consolidating of the Illinois regulatory structure, additional disparity studies, and more industry-state collaboration along with a set of administrative recommendations.

Puerto Rico’s 2019 and 2021 Greenhouse Gas Inventories Report

Client: Puerto Rico Department of Natural and Environmental Resources (DNER)

Authors: Liz Stanton, PhD, Joshua R. Castigliego, Chirag T. Lala, Sachin Peddada,
Jay Bonner, Eliandro Tavares, Sumera Patel, Alicia Zhang, Myisha Majumder,
David Jiang, and Jordan Burt; Ramón Bueno and Kari Hewitt

July 2023

On behalf of the Puerto Rico Department of Natural and Environmental Resources (DNER), AEC staff and partners prepared a report that presents the results for Puerto Rico’s 2019 and 2021 greenhouse gas emission inventories together with 20-year emissions projections under several scenarios and sensitivities. AEC established a methodology for conducting greenhouse gas emission inventories in Puerto Rico, which went through a comprehensive quality assurance and quality control process by an Expert Panel (established for this project and composed of experts in greenhouse gas emissions measurement and Puerto Rico climate and energy issues). Using AEC’s Emissions Measurement Inventory Tool (AEC-EMIT), AEC calculates net greenhouse gas emissions released in Puerto Rico’s seven emitting sectors: (1) Power Supply, (2) Direct Fuel, (3) Industrial Processes and Product Use, (4) Transportation, (5) Agriculture, (6) Forestry and Other Land Use, and (7) Waste Management.

Puerto Rico’s 2019 Climate Change Mitigation, Adaption, and Resiliency Law (i.e., Puerto Rico Act No. 33-2019) measures mandated emission reductions against an estimated 2005 emissions level of 53.3 MMT CO₂e and calls for a 50 percent reduction relative to 2005 emissions by 2025 (26.7 MMT CO₂e). Emission levels achieved in 2021 (34.3 MMT CO₂e) represent a 36 percent reduction in emissions from 2005 levels. With 14 percentage points and 4 years left to go, Puerto Rico must find another 7.7 MMT CO₂e to eliminate. Based on the Business-as-Usual projection in AEC’s analysis, Puerto Rico’s greenhouse gas emission levels will reach their mandated levels (50 percent of 2005 levels, or 26.7 MMT CO₂e) in 2035, 10 years later than the required 2025 target.

Based on the analysis presented in this report, AEC has identified several key recommendations to further facilitate Puerto Rico’s work towards achieving its ambitious and necessary decarbonization goals set out in Puerto Rico’s 2019 Climate Change Mitigation, Adaption, and Resiliency Law, including: (1) better data collection, (2) increased climate progress reporting (3) reprioritization in rebuilding its electric sector, and (4) a new focus in transportation planning.

The Interconnection Bottleneck: Why Most Energy Storage Projects Never Get Built

Image Credit: Sara Levine | Pacific Northwest National Laboratory

Client: Prepared on behalf of Clean Energy Group

Authors: Chirag Lala, Jordan Burt, Sachin Peddada

May 2023

On behalf of the Clean Energy Group, Researcher Chirag Lala and Assistant Researchers, Sachin Pedadda and Jordan Burt prepared a report that assesses the obstacles preventing efficient interconnection of distributed energy storage resources. This Applied Economics Clinic (AEC) white paper identifies and explains these interconnection barriers in Massachusetts and makes recommendations to state agencies and working groups overseeing interconnection, distribution utilities, independent system operators, and the Federal Energy Regulatory Commission.  

AEC staff make these five key recommendations to stakeholders: (1) Develop proactive, integrated, and system-wide interconnection planning that takes a systemic view of applications and separates hosting capacity upgrades from particular project or cluster applications and makes hosting capacity upgrades in anticipation of grid-needs and future interconnection volume. (2) Continuously iterate interconnection processes to build in regular improvements, examine effectiveness, and coordinate public and private stakeholders to tackle ad hoc coordination problems. (3) Tackle barriers and solutions comprehensively by integrating multiple solutions. (4) End cost causation by spreading distribution system upgrade costs over a broader set of stakeholders (including ratepayers) than just allocating those costs to the projects or clusters applying for interconnection. (5) Incorporate storage operational parameters into interconnection processes so that storage resources are assessed in a manner reflecting how they would reasonably be expected to operate once interconnected alone or in conjunction with technologies regulating bidirectional power flows and facilitating predictable charging and discharging.

Bringing Equity into Energy Reliability Decisions

Client: Environmental Defense Fund

Authors: Bryndis Woods, PhD, Sachin Peddada, Sagal Alisalad, Jordan Burt, Elisabeth Seliga, Tanya Stasio, PhD, Eliandro Tavares, Grace Wu, Elizabeth A. Stanton, PhD

AEC staff prepared a report on behalf of the Environmental Defense Fund that analyzes the connection between issues of energy system reliability and equity. This data-driven report utilizes case studies of advocates’ for more equitable energy systems real-world experiences to assess how decision-makers should account for equity when making decisions regarding system reliability. The report concludes with recommendations for future decision-making in energy system reliability, including strengthening consumer and community representation. A common theme across the real-world experiences of the advocates discussed in this report is the ways in which community engagement efforts in energy system decision-making often fall short of creating real change in energy sector decisions, and environmental justice and other under-resourced and underserved communities are often left out and left behind in decisions that directly disproportionately harm the health and wealth of their communities.

Overburdened Communities and Power Plants in New Jersey

Authors: Sagal Alisalad, Tanya Stasio, PhD, Elisabeth Seliga, and Sachin Peddada, and Jordan Burt

Assistant Researcher Sagal Alisalad, Researcher Tanya Stasio, PhD, Assistant Researchers Elisabeth Seliga, and Sachin Peddada, and Research Assistant Jordan Burt prepared a policy brief on how New Jersey power plants disproportionately affect overburdened communities.

New Jersey environmental justice law defines overburdened communities as census blocks where at least a third of the household is low income, 40 percent of residents identify as racial-ethnic minorities, or 40 percent have low English proficiency. These communities are disproportionately affected by the pollutants emitted by power plants. AEC researchers explain that environmental justice initiatives will require full understanding of the impacts on vulnerable communities.
