Energy Storage: A Cheaper, Faster & Cleaner Alternative to Conventional Frequency Regulation

California Energy Storage Alliance -  January 2011

To illustrate the value of energy storage in the ancillary services frequency regulation market, this paper examines a specific ancillary service -- frequency regulation -- and compares the performance of a flywheel kinetic energy storage device with a conventional baseload combined cycle combustion turbine. This paper also looks at how other energy storage technologies can provide frequency regulation, and includes examples of existing and developing projects.

Integrating Renewable Electricity on the Grid

Integrating Renewable Electricity on the Grid

KEMA Proposal_Report w Appendices Template 2008 Gas Flame 2

American Physicists Society – November 2010 

Renewable resources present a new set of technological challenges not previously faced by the grid: the location of these resources far from population centers, and the variability of renewable generation. Although small penetrations of renewable generation on the grid can be smoothly integrated, accommodating more than approximately 30% electricity generation from these renewable sources will require new approaches to extending and operating the grid, including Energy Storage.

Electric Energy Storage  Assessment of Barriers and Opportunities

Electric Energy Storage Assessment of Barriers and Opportunities

California Public Utility Commission - July 2010

California policymakers support the development of EES because it can provide an advantageous strategy for meeting the state’s long-term clean energy goals while maintaining system reliability. However, relatively little information about EES costs and benefits is available to form a rational basis for policy action. The purpose of this paper is to identify for policymakers the opportunities for and barriers to the development and deployment of EES technologies throughout California’s electricity system.

The Power of Energy Storage: How to Increase Deployment in California to Reduce Greenhouse Gas Emissions

The Power of Energy Storage: How to Increase Deployment in California to Reduce Greenhouse Gas Emissions

Sunshine and wind, even in California, are intermittent resources, while the state’s energy needs run twenty-fours hours of every day. As California seeks to expand solar and wind power, storage of that energy for use at any time, day or night, becomes critical.

Energy Storage: A Cheaper and Cleaner Alternative to Gas-Fired Peakers

California Energy Storage Alliance -  June 2010

This paper examines the cost effectiveness of energy storage as an alternative to natural gas-fired peakers, by performing a detailed analysis comparing the cost of a kilowatt-hour (kWh) of electricity generated on-peak by a gas-fired peaker, with the cost of a kWh of electricity provided on-peak by an energy storage system.

Research Evaluation of Wind Generation, Solar Generation, & Storage Impact on the California Grid

Research Evaluation of Wind Generation, Solar Generation, & Storage Impact on the California Grid

California Energy Commission - June 2010

This report analyzes the effect of increasing renewable energy generation on California’s electricity system and assesses and quantifies the systemʹs ability to keep generation and energy consumption (load) in balance under different renewable generation scenarios. In particular, researchers assessed four key elements necessary for integrating large amounts of renewable generation on California’s power system. Researchers concluded that accommodating 33 percent renewables generation by 2020 will require major alterations to system operations. They also noted that California may need between 3,000 to 5,000 or more megawatts (MW) of conventional (fossil‐fuel‐powered or hydroelectric) generation to meet load and planning reserve margin requirements.

ASHRAE: Energy Efficient TES Designs for Commercial DX Systems

ASHRAE: Energy Efficient TES Designs for Commercial DX Systems

ASHRAE - May 2010

This paper describes the basis for an energy efficient refrigerant-based thermal energy storage system design for commercial DX systems. A description of a system is given, and design aspects contributing to energy efficiency are identified. Similarly, operating characteristics and strategies contributing to energy efficiency are discussed. Challenges in measuring and predicting energy efficiency are identified, along with a proposed method for collecting certified performance data, and sample test results. Field data is then analyzed to determine if it is consistent with energy savings predictions. The benefits of using such energy efficient thermal energy storage systems are then considered for several climate zones. Results show that refrigerant-based thermal energy storage for commercial DX systems is energy neutral or better given specific design considerations and operating strategy.

Assessment of Jobs Benefits from Energy Storage

Assessment of Jobs Benefits from Energy Storage

KEMA Proposal_Report w Appendices Template 2008 Gas Flame 2

KEMA Inc. for the Electricity Storage Association - March 2010

This report examines job creation estimates associated with potential energy storage legislation. The analysis quantified the market size of key energy storage application areas and created an energy storage penetration model to examine the yearly megawatt (MW) market size based on the economic payback period and assessed how proposed incentives would increase market penetration. Incremental job creation was estimated based on increased market penetration and associated sales revenue generated by the incentives.
