EPRI launches decision tool for distributed energy resources


The Electric Power Research Institute (EPRI) launched what it is calling a Distributed Energy Resource Value Estimation Tool (DER-VET), designed to increase grid flexibility as more distributed energy resources (DER) are integrated into the electric grid.

The tool provides a free, publicly accessible, open-source platform for calculating, understanding, and optimizing the value of DER based on their technical merits and constraints. DER-VET was developed in collaboration with the California Energy Commission. The source code for DER-VET is available here.

An extension of EPRI’s StorageVET tool, DER-VET supports site-specific assessments for energy storage and additional DER technologies. Applications include valuations and impacts of energy storage, solar, wind, demand response, electric vehicle (EV) charging, internal combustion engines, and combined heat and power in different configurations, such as microgrids. Site conditions, load, and other data are used to determine the optimal size, duration, and other operational characteristics for maximizing DER project benefits.

StorageVET helps decision makers determine where to place and install energy storage, the optimum size, and which controls to include. StorageVET also aims to improve energy storage project planning by enabling rapid scenario analysis with different storage sizes, costs, and value streams.
