Sophia Greszczuk

Sophia Greszczuk supports E3’s work in distributed energy resources with an emphasis on energy storage and community solar projects. She has extensive experience running RESTORE, E3’s energy storage dispatch model, and generating revenue for specific battery assets. Ms. Greszczuk came to E3 after earning a Bachelor of Arts in Biology and Environmental Studies at Dartmouth University. There she was involved in environmental work both with the Sustainability Office and, through a grant earned from the Irving Institute, designing and installing off-grid solar. She also interned at the Climate Institute, investigating the effect of water-mediated microclimates on human health and economic growth.

 Sophia’s love of the outdoors and lifelong passion for the environment led her to a career at E3. She believes that large-scale energy decarbonization is one of the most powerful ways to fight climate change. Sophia appreciates the opportunity to do meaningful work, answering complex and interesting questions about distributed energy resources.

Outside of work, Sophia enjoys running, hiking, and finding any excuse to be outside. Sophia also loves sports, especially playing soccer and hockey and cheering on Boston teams.

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.
