Storage Value Estimation Tool (StorageVET®)

DER-VET™ Software

  • DER-VET™ is a publicly available, open-source, optimization-based energy valuation and planning tool for distributed energy resources (DER) and larger, centralized energy resources. DER-VET™ was developed by expanding on the framework devloped in EPRI's Storage Value Estimation Tool (StorageVET).

  • StorageVET 2.1

    StorageVET® 2.1 facilitates the understanding of where to place and install energy storage, the optimum size as well as controls options. StorageVET 2.1 implements dispatch optimization with sensitivity analysis to assist in planning energy storage project development by enabling rapid analysis of scenarios with different storage sizes, costs, and value streams. Additionally, StorageVET 2.1 is valuable as a research tool to inform broad-sweeping analyses of trends in storage value as a function of location, operation, and technical capabilities.

    StorageVET is a publicly available, open-source, Python-based energy storage valuation tool.

    Made possible through funding support from the California Energy Commission.

  • Reference Cases

  • Deferral Reference Case
  • Project Goals

    • Provide a consistent platform for communication of site-specific storage value between stakeholders of utilities, regulators, and vendors
    • Provide a publicly available tool and method to fairly, transparently, and consistently estimate the benefits and costs of energy storage projects across all cases
      • Grid Services
      • Technologies and Sizes
      • Locations
    • Provide guidance to identify and characterize high value locations to deploy energy storage, so that early successes in energy storage maximize value to all stakeholders

    Feature Highlights

    • Initially customized for California market services, reference scenarios, and data sets with direct import to the model
    • Broad coverage of energy storage technologies and other reference technologies (e.g. combustion turbine)
    • Flexible optimization horizon
    • Flexible simulation time step granularity
    • Utilizes the Gurobi optimization engine
    • Web-based user interface and free public access

    Get Involved

    • Stakeholders can participate in input and review of model definitions through participation in the Energy Storage Integration Council (ESIC), an open technical forum. More info can be found at www.epri.com/esic.
    • The ESIC collaboration site contains live draft user documentation from the ESIC StorageVET® Subgroup at collab.epri.com/esic.
    • Relevant documents can be accesssed via: ESIC Collaboration Site > WG1 - Grid Services and Analysis > WG1 Documents.
    • All documents and review opportunities will be facilitated through the Analysis Working Group of ESIC.
