Andrew Epstein is a power systems engineer at Sound Grid Partners where he provides a suite of services in analytics and engineering. He also provides subject area expertise in software products for energy applications.
Andrew previously worked as a technical product manager at Doosan GridTech where he designed and deployed software for large scale energy storage systems. In this role he oversaw the development and testing of new control features and coordinated with market regulators, scheduling entities, system developers, and hardware vendors to ensure the successful integration of control software for energy storage systems in several markets.
Andrew holds a bachelor’s degree in electrical engineering from Stanford University.
Marley Cross is a power systems engineer in analytics at Sound Grid Partners, where she provides a suite of services in analytics and engineering.
Marley previously worked as a solar performance analyst at Nexamp, where she built tools to maximize performance of distributed solar and storage resources. In this role, she designed analyses to optimize plant availability and troubleshot underperformance. She commissioned and troubleshot data acquisition system (DAS) equipment, and developed new workflows to streamline project hand-off during commissioning. She conducted performance testing and reporting, automating the performance testing process into a web-based tool that reduced manual analysis.
As a Quantitative Intern at Optimal Energy, Marley developed tools to compare costs and savings of energy efficiency resources to inform Rhode Island’s three-year energy efficiency planning process.
Marley holds a bachelor’s degree in economics and environmental studies from Brown University.
Jared Silvia is a consultant at Sound Grid Partners, where he leads engagements with electrical utilities and developers. Jared has experience in the cleantech, solar, and energy storage sectors with a specialty at breaking down strategic problems into operational actions.
Most recently, Jared co-founded BlueDot Photonics, a Seattle-based company working to commercialize next-generation solar and photonic technologies for a wide variety of applications and end uses. Jared works closely with solar panel manufacturers to understand the value of high efficiency solar panels and identify cost-effective methods for improving solar panel efficiency.
