Biography

Marie is a senior research associate in the Energy Transitions and Electric Power program at KAPSARC. Her current research focuses include power system modeling and market designs for energy transitions.

Prior to joining KAPSARC, Marie worked as a research engineer within the Research and Development (R&D) unit of the utility group EDF in Paris, France. During her EDF journey, she worked on long-term and short-term electricity market design, transmission grids at the European scale, and smart-charging opportunities for electric vehicles. Marie also worked as a researcher within the market department of the French Transmission System Operator RTE.

Marie holds a Ph.D. in Economics from Dauphine University, PSL (France), an M.Sc. in environmental and energy economics from École des Ponts ParisTech (France), and an M.Sc. in engineering from ENSTA Institut Polytechnique de Paris (France).

One Year After the Texas Blackout: Lessons for Reliable and Resilient Power Systems

One Year After the Texas Blackout: Lessons for Reliable and Resilient Power Systems

In February 2021, Texas experienced an extreme cold snap causing a dramatic electricity blackout that left millions of households without electricity, resulting in over 200 fatalities and economic damages of approximately $100 billion. The Texas blackout has been used to support a variety of claims regarding renewable energy, electricity markets and climate change. We identify the blackout’s drivers and what has been learned since then. These lessons apply to power systems worldwide, including those of the Gulf Cooperation Council and the broader Middle East and North Africa region.

Renewables, Reliability and Efficiency in Electricity Markets

Renewables, Reliability and Efficiency in Electricity Markets

The choice to use electricity markets to transition to an ultra-high renewable electricity sector depends on whether a high level of reliability and efficiency can be achieved. This study presents a reliability, resiliency and adaptability policy framework for a liberalized power system with a high share of renewables. This framework provides policy insights regarding electricity market reliability and the implications of remuneration mechanisms for renewables. Our analysis shows that it is necessary to reconsider adequacy assessments of liberalized power systems, to enhance the definition of the loss of load probability, and to explicitly consider the probability that the market clears. Under these conditions, electricity markets can theoretically achieve reliability and efficiency with large percentages of variable and intermittent renewable resources with zero or near-zero marginal costs, and market and technical challenges can be addressed.

Why is the EU Carbon Price at a Record €60 per Tonne?

Why is the EU Carbon Price at a Record €60 per Tonne?

Carbon prices soared above €60/tonne for the first time on August 30, 2021, with the expectation of tightened environmental legislation. These prices made a new record on the European Union Emission Trading System (EU ETS), the European Union’s carbon market. The stressed gas market and expectations of a tighter gas supply in Europe are also behind rising carbon prices. These factors spilled over into electricity prices, which also broke highs, hitting €140 per megawatt hour (MWh) in real-time trading on September 1, 2021.

Why are European Wholesale Electricity Prices Soaring?

Why are European Wholesale Electricity Prices Soaring?

Since the beginning of summer 2021, European wholesale electricity prices have been soaring to historic highs. The average day-ahead price of electricity for central European countries more than doubled between June and September, reaching 170 euros per megawatthour (e/MWh) on September 15. This data insight discusses this unprecedented increase in wholesale electricity prices and their key drivers.

Climate and Power System Reliability in the Aftermath of the Texas Blackouts

Climate and Power System Reliability in the Aftermath of the Texas Blackouts

The February 2021 blackout in Texas underscored the importance of reliable and resilient power systems. In this commentary, we discuss the roles of regulators, markets, fuel and generation supply chains, and interdependent infrastructures, and finds that they need to be reconsidered and redefined to successfully meet the future challenges of increased electrification and severe weather.
