  • 2014 Storage Plan Assessment Recommendations for the U.S. Department of Energy

    Posted: September 25, 2014 - 17:00 / DOE EAC / Reports

    This report, approved at the September 2014 EAC meeting, summarizes a review of DOE’s energy storage program strategies and activities, and includes recommendations that the Electricity Advisory Committee (EAC) offers for the DOE’s consideration as it continues to develop and implement its energy storage program.

  • Inventory of Safety-related Codes and Standards for Energy Storage Systems

    Posted: September 19, 2014 - 15:00 / PNNL / Reports

    The purpose of this document is to identify laws; rules; model codes; and codes, standards, regulations (CSR) specifications related to safety that could apply to stationary energy storage systems (ESS) and experiences to date securing approval of ESS in relation to CSR. This information is intended to assist in securing approval of ESS under current CSR and to identification of new CSR or revisions to existing CSR and necessary supporting research and documentation that can foster the deployment of safe ESS.

  • Overview of Development and Deployment of Codes, Standards, and Regulations Affecting Energy Storage System Safety in the United States

    Posted: August 8, 2014 - 19:00 / PNNL / Reports

    The purpose of this document is to acquaint stakeholders and interested parties involved in the development and/or deployment of energy storage systems (ESS) with the subject of safety-related codes, standards and regulations (CSRs). It is hoped that users of this document gain a more in depth and uniform understanding of safety-related CSR development and deployment that can foster improved communications among all ESS stakeholders and the collaboration needed to realize more timely acceptance and approval of safe ESS technology through appropriate CSR.

  • Morgan Stanley Blue Paper - Solar Power & Energy Storage: Policy Factors vs. Improving Economics

    Posted: July 29, 2014 - 05:00 / Finance / Reports

    Morgan Stanley has developed a model that calculates solar economics around the world based on local regulatory dynamics and solar conditions. Morgan Stanley asserts that investors can use this analytical framework to better understand solar economics in the context of local regulatory dynamics, solar installation costs, and solar operating conditions.

  • Estimating the Value of Utility-Scale Solar Technologies in California Under a 40% Renewable Portfolio Standard

    Posted: June 11, 2014 - 01:02 / NREL / Reports

    With growing interest in renewable energy, the penetration of solar photovoltaics (PV) and wind generation is likely to rise. Accommodating the time-varying and uncertain output of these resources will be a challenging aspect of integrating large-scale renewable energy into the electric power system. Concentrating solar power (CSP) with thermal energy storage (TES) is a unique source of solar energy in that its output can be shifted over time and also controlled in response to system operator signals, allowing for provision of a wide range of grid services. The ability of CSP-TES to be a flexible source of renewable generation may be particularly valuable in regions with high overall penetration of solar energy, such as the state of California.

  • Protocol for Uniformly Measuring and Expressing the Performance of Energy Storage Systems

    Posted: June 6, 2014 - 15:00 / PNNL / Reports

    The Protocol for Uniformly Measuring and Expressing the Performance of Energy Storage Systems (PNNL-22010) was first issued in November 2012 as a first step toward providing a foundational basis for developing an initial standard for the uniform measurement and expression of energy storage system (ESS) performance. Its subsequent use in the field and review by the protocol working group and most importantly the users’ subgroup and the thermal subgroup has led to the fundamental modifications reflected in this update of the 2012 Protocol.

  • Executive Summary: Survey of Modeling Capabilities and Needs for the Stationary Energy Storage Industry

    Posted: May 21, 2014 - 19:00 / ESA / Reports

    Energy Storage (ES) can be used to enhance and support the electric distribution and transmission network, and support the integration and operation of intermittent electric generating resources. The first pumped storage hydroelectric project in the United States was developed nearly a century ago. Compressed air energy storage (CAES) plants have been operated commercially for a few decades. Thermal storage integrated with concentrating solar plants has been operated at utility-scale for about eight years. Ice storage is also being used to shift electrical demand and consumption to off-peak periods in commercial deployments. More recently, battery and flywheel based systems have begun commercial operations on the grid to provide ancillary services, and have met performance requirements.

  • IMechE Report - Energy Storage: The Missing Link in the UK’S Energy Commitments

    Posted: April 10, 2014 - 09:00 / IMechE / Reports

    Energy storage provides a potential route to a solution to this challenge, in that it would enable wrong-time electricity generated from intermittent renewable sources to be put to use at times when consumer demand is higher than baseload provision and renewables supply is at low levels. It would also help to address the seasonal challenge. In this regard consumer demand for power and heat is typically higher in the winter months than in the summer, and longer-term storage would allow energy from renewable sources to be carried over from one season to the next. The use of energy storage in both these ways would allow greater returns on investment to be made from deployed renewable energy technologies. Other benefits from storing energy in the UK can include deferring the costs associated with upgrading energy distribution systems to supply expanding towns and urban areas, as well as allowing communities to become more self-sufficient in energy sourcing and management.

  • ILSR Report - Energy Storage: The Next Charge for Distributed Energy

    Posted: March 26, 2014 - 19:51 / ISLR / Reports

    Energy storage promises to change the electricity system during the next decade, as fundamentally as distributed renewable energy has in the last decade. A new report from the Institute for Local Self-Reliance, Energy Storage: The Next Charge for Distributed Energy, forecasts where the battleground is shaping up.
