Meet the Expert: Marilyn Brown

Modeling how the U.S. can meet changing energy needs — today and tomorrow An illustrious career focused on understanding the nuances of energy policy through analytics has shaped the career of Marilyn Brown, the Regents & Brook Byers Professor of Sustainable Systems at the Jimmy and Rosalynn Carter School of Public Policy at Georgia Tech. […]

Small Modular Reactors and Smart Energy Cities

A new study by Georgia Tech researchers Brian An, Daein Kang, John Kim, and Moe Kyaw Thu analyzes how national governments describe Small Modular Reactors (SMRs) in official energy policy documents. Using natural language processing (NLP) on more than 800,000 words extracted from 66 national and international energy plans, the authors assess whether SMRs are […]

Meet the Expert: Dan Matisoff

Policies for greening the grid: rooftop solar panels and community solar programs As an undergraduate at the University of Pennsylvania, Daniel Matisoff was intrigued by the ability of economic markets to help solve environmental problems. “Learning about the regulatory role of governments in cap-and-trade markets for reducing carbon emissions shaped my career path,” says Matisoff, […]

Wind intermittency and supply-demand imbalance: Evidence from U.S. regional power markets

Listen to the podcast: This study examines how short-term variability in wind power—known as wind intermittency—affects real-time electricity system imbalances in U.S. regional power markets. The authors, Victoria Godwin and Matthew E. Oliver of the Georgia Institute of Technology and EPIcenter affiliates, analyze data from four major system operators: Bonneville Power Administration (BPA), New York […]

Effects of grid expansion on market power in the fossil fuel industry

In “Wiring America,” EPIcenter affiliate Gaurav Doshi analyzes how Texas’s CREZ high-capacity transmission build-out curbed the market power of fossil-fuel generators. Using a two-stage empirical strategy, the study first shows that CREZ reduced wind curtailment, adding roughly 0.11 GWh of additional wind during peak hours and 0.22 GWh at the off-peak – and then demonstrates […]

Pipeline congestion and natural gas spot price basis differentials

This paper authored by EPIcenter affiliate Matt Oliver dicusses how pipeline congestion in the U.S. Rocky Mountain region creates sizable price wedges, or “basis differentials,” between closely linked hubs—Opal, WY, and Cheyenne, CO. As demand for transport approaches capacity on the 325-mile corridor (via CIG, WIC, and REX), secondary market scarcity rents drive the Cheyenne […]

The effect of renewable electricity generation on the value of cross-border interconnection

In a world shifting toward renewable power generation, the way we connect our power grids may matter more than ever. Using data from 155 regions on five continents, this study authored by EPIcenter affiliate Constance Crozier shows that linking neighboring grids via high‐voltage direct current (HVDC) lines can replace—or drastically reduce—the need for expensive batteries. […]

Effects of grid expansion on long-run renewable investment

This paper by EPIcenter affiliate Gaurav Doshi examines how Texas’s $6.8 billion CREZ transmission expansion catalyzed wind deployments in the West and Panhandle region. Employing a discrete choice framework, developers were found to be 20 percentage points more likely to locate in CREZ counties, implying a willingness to pay of roughly $2,808 per MW of […]

Curtailment 101: Understanding the Basic Economic Trade-Offs

Listen to the Curtailment 101 podcast: EPIcenter affiliates Gaurav Doshi and Matthew Oliver’s article in The Energy Forum discusses the why grid operators occasionally curtail wind and solar output when transmission capacity is insufficient or demand is low, and the economic and environmental impacts of these decisions. Congestion-based curtailment arises when the transmission network cannot […]
