  • NIST Framework and Roadmap for Smart Grid Interoperability Standards

    Posted: January 21, 2010 - 16:34 / NIST / Reports

    Under the Energy Independence and Security Act of 2007 (EISA), the National Institute of Standards and Technology (NIST) is assigned the “primary responsibility to coordinate development of a framework that includes protocols and model standards for information management to achieve interoperability of Smart Grid devices and systems…” [EISA Title XIII, Section 1305]. There is an urgent need to establish protocols and standards for the Smart Grid. Deployment of various Smart Grid elements, including smart sensors on distribution lines, smart meters in homes, and widely dispersed sources of renewable energy, is already underway and will be accelerated as a result of Department of Energy (DOE) Smart Grid Investment Grants and other incentives, such as loan guarantees for renewable energy generation projects.

  • Benefits from Flywheel Energy Storage for Area Regulation in California— Demonstration Results

    Posted: October 1, 2009 - 19:00 / CAISO / Reports

    This report documents results from a demonstration of flywheel electric energy storage (flywheels) for area regulation, an ancillary service required for electric grid operation. The work was sponsored by the California Energy Commission’s (CEC’s) Public Interest Energy Research (PIER) program and the U.S. Department of Energy’s Energy Storage Systems Program. The flywheel is made by Beacon Power Corporation (Beacon Power).

  • Capturing Grid Power: Performance, Purpose, and Promise of Different Storage Technologies

    Posted: August 11, 2009 - 05:05 / IEEE / Reports

    Although energy storage in utility grids has existed for many decades, the impact of storage in future grids is receiving more attention than ever from system designers, grid operations and regulators. The amount of storage in a grid and its value is also a subject of debate. Understanding the leading storage technologies and how they can affect grid operations is an important first step in this assessment.

  • Load Leveling Reduces T&D Line Losses

    Posted: October 8, 2008 - 04:58 / IEEE / Reports

    The benefit of shifting load from the peak to the off-peak period is well known from the viewpoints of demand response and deferral of capacity upgrade. However, the impact of load leveling on reducing transmission and distribution (T&D) losses is often ignored or lightly mentioned in the literature. A detailed analysis of T&D loss reduction is very specific to the considered power system and cannot be readily generalized.

  • Guide to Estimating Benefits and Market Potential for Electricity Storage in New York

    Posted: March 15, 2007 - 12:39 / NYSERDA / Reports

    This document describes a high level, technology-neutral framework for assessing potential financial benefits from and maximum market potential for electric energy storage. More specifically, it addresses electric utility-related applications, in New York, with an emphasis on New York City (NYC) – designated as Zone J by the New York Independent System Operator (NYISO).

  • Emissions Comparison for a 20 MW Flywheel-based Frequency Regulation Power Plant

    Posted: January 8, 2007 - 19:00 / Reports

    KEMA Inc. was commissioned by Beacon Power to evaluate various performance aspects of the Beacon Power 20 MW flywheel-based frequency regulation power plant, including its emissions characteristics. To support the emissions evaluation, a detailed model was created to compare the emissions of CO2, SO2 and NOx for a Beacon Power flywheel plant versus three types of commercially available power generation technologies used in the market to perform frequency regulation ancillary services.
