EPRI releases open-source Distributed Energy Resource Value Estimation Tool

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 limitations. DER-VET was developed in conjunction with the California Energy Commission (CEC).

“DER-VET enables developers, utilities and regulators in the power industry to make more informed DER application decisions based on a comprehensive, realistic data set,” said Daniel Brooks, VP Integrated Grid and Energy Systems at EPRI. “Innovative tools are essential to get more value from increasingly complex DER solutions that enable greater flexibility and reliability of the power grid.”

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

“Investments in clean energy innovation, such as the CECs EPIC grants to support the development of DER-VET are critical to accelerating California’s transition to a zero-carbon energy system, ”said David Hochschild, president of CEC. “This tool is another important link to better use and integrate our renewable and distributed energy sources, in support of a more dynamic, responsive and reliable grid.”

StorageVET, EPRI’s storage estimation tool and predecessor to DER-VET, helps decision-makers determine where to place and install energy storage, what the optimal size is and what controls to include. StorageVET also improves energy storage project planning by enabling rapid analysis of scenarios with different storage sizes, costs and value streams.
