Dr. Yang specializes in the development of economic models to conduct economic and policy analyses in the energy industry, with a focus on the power sector.

Her work focuses on long-term system and market outlook, integrated resource planning, generation asset evaluation, power price forecast, and environmental policy analysis.

Prior to joining Brattle, Dr. Yang worked for Charles River Associates, where she led the modeling effort of MRN-NEEM (Multi-Regional National Model-North American Electricity and Environment Model), a model that couples a computable general equilibrium model across all sectors of the U.S. economy with a detailed simulation model of the electricity sector.

Dr. Yang previously worked at the MIT Energy Initiative during her postdoctoral research, where she participated in a large interdisciplinary MIT study entitled, “The Future of Natural Gas.” At the MIT Energy Initiative, she led the quantitative analysis of the impacts of a U.S. climate policy on natural gas consumption in the power sector by employing the MARKAL model. While at MIT, she also co-founded the MIT China Energy and Environmental Research Group and served as a co-president to lead the group’s activities.

Representative Engagements
Power Plant Asset Evaluation
Provided analysis for a private equity investment firm that advised their decisions on purchasing a power plant in Arizona based on long-term power prices and the plants’ costs.
Power Plant Investment Opportunity Assessment
On behalf of an electricity power plant developer, led an analysis that assessed the potential market investment opportunity for wind, solar, and gas technologies and the impacts of the EPA’s proposed Clean Power Plan on these market outlooks in Eastern Interconnection.
Long-term System Outlook
For the Texas Clean Energy Coalition, performed multiple analyses over several years analyzing the long-term system evolution at ERCOT with an emphasis on clean energy development, demand-side resources, and GHG emissions reduction.
Renewable Integration in China
Conducted a comparative study of renewable integration between Texas in the U.S. versus Inner Mongolia in China, concentrating on aspects of system planning, market structure, system operation, and renewable policies. We identified the reasons for the high wind curtailment in Inner Mongolia, and provided recommendations for improvement based on the successes in Texas.
Regional Long-Term Power and Carbon Price Forecast
Estimated damages claims during a contract dispute by conducting an analysis to forecast power and carbon prices in Western Interconnection through a long-term capacity expansion model. The analysis involved modeling the entire Western Interconnection electricity system and also California’s Cap and Trade program that covers the emissions for all sectors.
