Blue Marble Analytics provides consulting and software-development services for power-system planning. Our goal is to create innovative, high-quality grid analytics software to guide clean energy policy and planning, and to build technical capacity to understand low-carbon grids.


Ana Mileva founded Blue Marble Analytics in 2016 and is the primary architect of GridPath, Blue Marble's grid-analytics software platform. Ana has extensive experience developing and applying various tools for electricity grid planning and operations, focusing on procurement of renewable energy resources, transmission, storage, and other renewables integration solutions. Her models have been used by government agencies, utilities, and developers to support integrated resource planning, market participation benefits analysis, and asset valuation. Ana holds a PhD from the Energy and Resources Group and an MPP from the Goldman School of Public Policy at the University of California, Berkeley.
