Ruoshui Li

Ruoshui Li works in E3’s resource planning area, providing utilities with analysis to enhance their planning efforts for resource adequacy. Her recent projects include characterizing the benefits of a regional resource adequacy program in the Desert Southwest and exploring capacity market rules for Independent System Operators (ISOs) on the east coast. She also uses E3’s RECAP model to help clients in the Pacific Northwest to characterize reliability challenges facing the region in a manner that is broadly accessible to regulators, policymakers, and stakeholders.

Prior to E3, Ruoshui interned with Tsinghua University Research Center for Energy Transition where she conducted rigorous studies on the renewable integration policies of European countries. She also interned at Wood Mackenzie Power & Renewables where she helped design models to automate wind speed database setup and power output simulation.

Seeing the electric industry as the keystone of economy-wide decarbonization goals, Ruoshui is passionate about assisting utilities to craft comprehensive strategies for facilitating a seamless and reliable transition. She also appreciates the opportunity of leveraging E3’s in-house model toolkit to dive deep into the increasingly complex resource adequacy world.

Outside of work, Ruoshui enjoys swimming and playing instruments. She also loves the food and culture of Latin America.

Energy Storage Market Update and Long Duration Storage Study | Massachusetts Clean Energy Center, 2023

In collaboration with the Massachusetts Clean Energy Center (MassCEC) and Department of Energy Resources (DOER), E3 conducted a study that assesses the current state of energy storage in the Commonwealth, the market outlook for emerging mid- and long-duration storage (LDES) technologies, and potential applications of mid- and long-duration storage, all in the context of providing benefits to ratepayers and achieving the state’s ambitious decarbonization goals.

The study included several modeling and stakeholder engagement elements. Leveraging E3’s pro forma financial model of storage technology costs and a custom-built storage dispatch model, the project team analyzed several storage use cases to help the state understand impacts of current incentive programs. Assessment of future storage value involved loss-of-load probability modeling of the entire ISO-NE footprint using E3’s RECAP model. E3 engaged stakeholders throughout the study process through interviews with more than 50 key stakeholders and two public stakeholder workshops. In the study, E3 shows that the role of energy storage changes to suit grid needs, but that storage requires well-designed state support to encourage deployment and innovation that targets these needs. In addition to writing a report providing study findings, the team worked with DOER to translate findings into policy recommendations for the state.

Resource Adequacy in the Desert Southwest

In the aftermath of recent blackouts in California and Texas, the subjects of reliability and resource adequacy have risen to national prominence. Regulators and policymakers – as well as the general public and media – have taken a keen interest in these topics, and many have questioned whether the industry is adequately prepared to confront […]
