  • Energy Storage Valuation Under Different Storage Forms and Functions in Transmission and Distribution Applications

    Posted: June 16, 2014 - 19:00 / IEEE / White Papers

    In this paper, we analyze and quantify functional value streams of energy storage under different forms (state in which energy is stored) and network location (e.g., transmission or distribution sides). First, we consider a transmission connected thermal form of storage coupled with concentrating solar power. Using the California power grid as a case study, we show that the coupled unit is significantly less volatile in its response and, through its load following, day-ahead dispatching, and regulation capabilities, it produces significant cost savings.

  • White Paper Analysis of Utility-Managed, On-Site Energy Storage in Minnesota

    Posted: December 28, 2013 - 19:35 / White Papers

    Pursuant to legislation passed in 2013, the Minnesota Department of Commerce (Commerce) contracted with Strategen and the Electric Power Research Institute (EPRI) to investigate the potential costs and benefits of grid-connected electrical energy storage technology located at the utility customer in the State of Minnesota. The investigation included standalone storage and storage integrated with solar PV, and it considered both residential and commercial customer sites.

  • Estimating the Value of Electricity Storage Resources in Electricity Markets

    Posted: November 22, 2013 - 12:52 / EAC / White Papers

    The purpose of this report is to assist the U.S. Department of Energy (DOE) in 1) establishing a framework for understanding the role electricity storage resources (storage) can play in wholesale and retail electricity markets, 2) assessing the value of electricity storage in a variety of regions or markets, , 3) analyzing current and potential issues that can affect the valuation of storage by investors at the wholesale and retail level, and 4) identifying areas for future research and development for electricity storage technologies and applications.

  • Future Ancillary Services in ERCOT

    Posted: September 27, 2013 - 12:20 / ERCOT / White Papers

    Over the years, ERCOT has been successful in complying with the National Electric Reliability Corporation (NERC) standards with the Ancillary Services (AS) that it has procured and deployed. For example, ERCOT’s average monthly Control Performance Standard (NERC CPS1) scores have consistently been around 165% over the last year, which is a clear indication that ERCOT is performing extremely well in controlling frequency. Other performance measures also reflect that the ERCOT AS construct currently in place has served ERCOT well from a reliability and secure operations perspective.

  • SBC Energy Institute Electricity Storage Factbook

    Posted: September 17, 2013 - 12:44 / White Papers

    Published in September 2013 by the SBC Energy Institute, a non-profit organization founded in the Netherlands, this Electricity Storage Factbook seeks to capture the current status of and future developments in electricity storage, detail the main technological hurdles and areas for Research and Development, and analyze the economics of a range of technologies.

  • Electricity Energy Storage Technology Options: A Primer on Applications, Costs and Benefits

    Posted: December 14, 2010 - 13:02 / EPRI / White Papers

    This paper describes in detail 10 key applications which can support the entire chain of the electrical system, from generation and system-level applications through T&D system applications to end-user applications. Included are: wholesale energy services, renewables integration, large and small storage and transportable systems for T&D grid support, ESCO aggregated systems, commercial and industrial power quality and reliability, commercial and industrial energy management, home energy management, and home back-up storage.

  • IEC Electrical Energy Storage Whitepaper

    Posted: October 5, 2010 - 19:00 / IEC / White Papers

    Electrical Energy Storage, EES, is one of the key technologies in the areas covered by the IEC. EES techniques have shown unique capabilities in coping with some critical characteristics of electricity, for example hourly variations in demand and price. In the near future EES will become indispensable in emerging IEC-relevant markets in the use of more renewable energy, to achieve CO2 reduction and for Smart Grids.

  • Energy Storage in the New York Electricity Markets

    Posted: March 18, 2010 - 13:10 / NYISO / White Papers

    This paper reviews existing energy storage technologies, discusses the NYISO’s efforts to integrate new energy technologies such as limited energy storage devices, and looks at future initiatives and technologies.

  • Energy Storage for the Electricity Grid: Benefits and Market Potential Assessment Guide

    Posted: February 18, 2010 - 13:18 / DOE / White Papers

    This guide describes a high-level, technology-neutral framework for assessing potential benefits from and economic market potential for energy storage used for electric-utility-related applications. The overarching theme addressed is the concept of combining applications/benefits into attractive value propositions that include use of energy storage, possibly including distributed and/or modular systems.
