Small Systems, Big Impact: Microgrids and the Next Era of Energy

In late April, a massive power outage swept across parts of Spain and Portugal. Within minutes, trains stopped, flights were grounded, and critical services were knocked offline. Even though most power was restored within 24 hours, the blackout was a wake-up call, showing just how one problem in a tightly connected grid can ripple outward […]

Supporting innovators: Policy design for growing Georgia’s energy ecosystems Part of EPIcenter’s mission is to foster an energy innovation ecosystem in the Southeast. This includes making Georgia an attractive place for energy and cleantech-focused startup companies and helping them succeed. But that success does not depend on the founder’s creativity and stamina alone. A mix […]

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 […]

Framework for estimation of the direct rebound effect for residential photovoltaic systems

Residential rooftop solar adoption can paradoxically lead to higher total electricity consumption than expected because “free” PV electricity lowers household energy costs, prompting some additional usage. EPIcenter affiliate Oliver and his Georgia Tech colleague Toroghi propose an innovative method that pairs economic demand modeling with high-resolution GIS PV potential analysis to estimate this “direct rebound […]

Willingness to pay for electricity reliability: evidence from U.S. generator sales

Our electrical grid—already under stress from climate‐amplified storms and the push to renewables—is a critical lifeline. Yet outages are costly, and until now, our best measures of how much U.S. households are truly willing to pay to avoid losing power (their “value of lost load,” or VoLL) came from surveys and macroeconomic models, offering wildly […]

Microeconomics of the solar rebound effect

A recent study by Matthew E. Oliver from the Georgia Institute of Technology and his co-authors, Juan Moreno-Cruz from the University of Waterloo and Kenneth Gillingham from Yale University, delves into the solar rebound effect. The “solar rebound effect” is a phenomenon where households with residential solar photovoltaic (PV) systems end up consuming more electricity in response to greater solar energy […]

Equitably allocating wildfire resilience investments for power grids

Climate-driven wildfires are increasingly ignited by overhead power lines, prompting utilities to deploy preemptive Public Safety Power Shutoffs (PSPS). Equitably Allocating Wildfire Resilience Investments for Power Grids studies how the Biden Administration’s Justice40 mandate (40 % of federal infrastructure benefits to disadvantaged communities via the CEJST index) actually plays out in a Texas case study […]

Turning up the heat: Georgia Tech economist finds price has little impact on consumers’ thermostat choices

In a study by a Georgia Tech economist that could help inform future energy policy, half the participants cranked their thermostats despite knowing exactly how much each extra degree would cost them. Prices are typically the first tool used to get people to save energy, noted Dylan Brewer, assistant professor in the Georgia Tech School of Economics. […]

To save energy, users let smart thermostats take the lead

People using energy-efficient smart thermostats are willing to sacrifice comfort and control to save relatively small amounts of energy that could add up if enough people sign on, a Georgia Tech economist reported in a recent study. With federal and state energy policies targeting aggressive decarbonization in the next 15 years, smart technologies have the […]

Who benefits most from rooftop solar capacity?

Who breathes cleaner air when Americans put solar panels on their roofs? Using plant-level emissions data, an air-pollution transport model, and census-block demographics, Bobby Harris (Georgia Tech)—the study’s EPIcenter affiliate— and Travis E. Dauwalter (Artera Services) show that today’s rooftop solar fleet delivers $0.77 in environmental benefits per person annually and disproportionately benefits higher-income households. […]

A field experiment on workplace norms and electric vehicle charging etiquette

Workplace EV charging congestion threatens corporate decarbonisation targets. Asensio, Apablaza, Lawson and Walsh (Georgia Tech; EPIcenter affiliate Omar I. Asensio) examine whether a tiered price of $1 per hour after 4 hours and injunctive “charging-etiquette” emails can curb charger over-stay across 105 stations and 84 employees. High-frequency session data are analyzed with sharp and dynamic […]

Housing policies and energy efficiency spillovers in low and moderate income communities

Federal housing block grants may be an untapped tool for energy-efficiency policy. EPIcenter affiliate Omar Asensio and his coauthors Churkina, Rafter and O’Hare (Georgia Tech, Harvard Business School and Georgia State University) link 5.9 million monthly utility bills with 16 years of Community Development Block Grant (CDBG) and HOME Investment Partnerships projects in Albany, GA […]

Chance-constrained multi-stage stochastic energy system expansion planning with demand satisfaction flexibility

How can a country minimize long-term power-system costs when future electricity demand is uncertain? Yuang Chen (PhD ISyE Georgia Tech and now assistant professor at the Chinese University of Hong Kong at Shenzhen), Beste Basciftci (PhD ISyE Georgia Tech and now assistant professor at the University of Iowa) and Georgia Tech’s Valerie M. Thomas (an […]

Managing Vehicle Charging During Emergencies via Conservative Distribution System Modeling

When a hurricane is coming, can a city with lots of electric cars top-up all those batteries fast enough without frying the local power grid? Three Georgia Tech engineers—Alejandro Owen Aquino, Samuel Talkington and EPIcenter affiliate Daniel Molzahn—built a computer model to find out.   Using realistic-but-not-real data from Greensboro, North Carolina, the model shows that […]
