NYSEG Seneca CAES Project Lessons Learned Webinar

Posted: 09-18-12

The U.S. Dept. of Energy (DOE) will host a free webinar 1:30 - 3:00 p.m. EDT Oct. 15, 2012, on Lessons Learned from the Seneca Compressed Air Energy Storage (CAES) project.

The New York State Electric & Gas Corporation's (NYSEG) experience of the Seneca CAES project yielded an extensive, innovative information base for use by other entities exploring utility-scale bulk energy storage. The nominal 150 Megawatt Seneca project was discontinued due to a combination of financial factors, including plant capital costs and the state of the New York wholesale electricity market now and in the foreseeable future, but it yielded valuable insights into developing large storage facilities. Although based on CAES project experience, many of the lessons are independent of geography, geology, or the storage technology being used.

The project was funded by a Cooperative Agreement from the DOE's Smart Grid Demonstration Program as part of the American Recovery and Reinvestment Act (ARRA) and managed by the DOE National Energy Technology Laboratory (NETL).

Dr. Imre Gyuk, DOE Storage Systems Program Manager, will provide a brief introduction and James Rettberg of NYSEG, Principal Investigator, will present an overview of the Seneca Project Phase 1 results and formal report. The Seneca Phase 1 Report (including numerous appendices of all underlying detailed reports and documentation) will be available for download prior to the webinar via the website.

DOE Energy Storage Systems and Clean Energy States Alliance Present Webinar on Federal Regulatory Energy Storage Policy January 25, 2012

Posted: 01-26-12

As part of Clean Energy States Alliance's Energy Storage Technology Advancement Partnership, the U.S. Department of Energy (DOE) Energy Storage Systems (ESS) program and the Clean Energy States Alliance hosted a webinar on Jan. 25, 2012, that discussed Federal Regulatory Energy Storage Policy, as part of a series exploring the national and state landscape for energy storage.

In late 2011, the Federal Energy Regulatory Commission (FERC) issued Order 755, which directs grid operators -- the ISOs -- to compensate resources that provide frequency regulation of the grid based on their efficiency and efficacy. In some cases, this will mean a larger role for storage devices, such as batteries and flywheels, in lieu of traditional generators. This webinar reviews the federal regulatory landscape for energy storage, specifically FERC Order 755, FERC Order 890 (which directs ISOs/RTOs to develop tariffs, market rules, and control algorithms and to open markets for new technologies that provide ancillary services), and other aspects of FERC treatment of energy storage and how these affect ISOs, energy storage device owners, and energy storage technology manufacturers.

The speakers include Dr. Imre Gyuk, manager of the DOE's ESS program; Dr. Bob Hellrich-Dawson, FERC economist; Ruston Ogburn, senior lead engineer with PJM Interconnection; Eric Hsieh, manager of Regulatory Affairs with A123 Systems; and Praveen Kathpal, vice president of Market and Regulatory Affairs with AES Energy Storage.

The webinar presentation slides are available for PDF download (PDF, 4.15 MB). Also, video of the webinar is available from the Clean Energy States Alliance website (WMV, 83 MB).

Sandia Labs Engineer Consults on Utah CAES Project

Posted: 12-05-12

Sandia National Laboratories has been working with Magnum Gas Storage and the state of Utah by providing core sample drilling and other test support in an initiative to develop a large compressed air energy storage system, or CAES, in a 2-mile-wide salt cavern.

In a recent Explore Utah Science article for KCPW public radio titled "Can We Store Energy From the Sun and Wind?," Sandia National Laboratories geo-mechanics engineer Stephen Bauer explains the fundamentals of how such CAES systems work.

"Basically, you store the energy as a compressed gas by pumping it underground when electricity is inexpensive, or there's extra energy that you can't use otherwise," says Bauer. "And you let it out, and harvest that energy."

Such CAES systems can store hundreds of megawatt-hours of surplus energy for large grid-scale applications.

Sandia's web tool helps determine best energy storage options

Posted: 05-09-12

Sandia National Laboratories and the Department of Energy have released a new tool to help utilities, developers and regulators identify the energy storage options that best meet their needs.

Partnering with DNV-KEMA, a global testing and consulting firm, Sandia is releasing Energy Storage Select, or ES-Select, software under a public license to the company. The tool makes it easier to conduct a quick, high-level analysis of energy storage options and determine the value of energy storage technologies for a specified application, which developers say will increase the adoption of energy storage technologies.

"ES-Select is the first of a suite of easily accessible web tools to help potential users and regulators to make decisions on energy storage options in specific applications," said Imre Gyuk, program manager of DOE's Energy Storage program.

The application is available for free download on the ES-Select page. "This tool is designed to help users to understand at a high level what storage can do. If it looks beneficial from a cost standpoint, they can explore the options further," said Sandia project manager Dhruv Bhatnagar.

Utilities and developers who want to use energy storage have many technologies to consider, including flywheels, compressed air, pumped hydro and thermal storage and six types of electric batteries. All have different costs, and estimating revenue from using various applications is difficult. Researching all relevant cost factors independently could take days or weeks in the past, but ES-Select aggregates all relevant factors into a single decision-support tool that runs in a few minutes. If the results are favorable for a particular technology, users can determine whether to run detailed, site-specific analysis using other tools.

"ES-Select is an educational and decision-support tool for deployment of energy storage on the power grid," said Ali Nourai, executive consultant for DNV-KEMA, and co-developer of ES-Select. "It has been created for public use to promote the understanding of storage technologies and the benefits they offer when applied on the electric grid."

The tool aids decisions about what storage technologies would work best in a given situation. For example, if a business pays more for electricity during the day than at night, the owner could use the tool to quickly evaluate several energy storage options to determine the cost-benefit of buying lower-cost electricity at night and storing it for use during the day.

Users can input the application they are interested in, as well as such parameters as energy costs and discount rates. The program produces a list of storage technologies and their predicted benefits and associated costs. ES-Select aggregates all of the inputs and assumptions -- monetary value for an application, technology costs, performance characteristics and operation and maintenance costs -- and quickly spits out recommended options.

Rather than basing decisions on a single factor such as capital cost, ES-Select assesses how an energy storage technology performs while addressing uncertainties in application value, storage cost, cycle life, efficiency, discharge duration and other parameters.

"With funding from DOE's Energy Storage Program, Sandia has worked with KEMA to develop a user friendly, freely accessible tool to evaluate potential applications of energy storage," said Gyuk. "We hope that this tool will contribute to the widespread adoption of storage on the grid."

ES-Select should benefit utilities, independent power producers, industrial and commercial enterprises, regulators, lawmakers and the public, including those doing research on energy storage. "We've already had a lot of people asking about this program, and we know many are anxious to use it," said Bhatnagar. "I think this will encourage those who might not have considered energy storage before to think more seriously about it and evaluate its potential as a viable option."

Sandia National Laboratories researchers find energy storage "solutions" in MetILs

Posted: 02-17-12

Sandia researchers have developed a new family of liquid salt electrolytes, known as MetILs, that could lead to batteries able to cost-effectively store three times more energy than today's batteries. The research, published in Dalton Transactions, might lead to devices that can help economically and reliably incorporate large-scale intermittent renewable energy sources, like solar and wind, into the nation's electric grid.

The grid was designed for steady power sources, making fluctuating electricity from intermittent renewable energy difficult to accommodate. Better energy storage techniques help even out the flow of such fluctuating sources, and Sandia researchers are studying new ways to develop a more flexible, cost-effective and reliable electric grid with improved energy storage.

Comments Requested

DOE seeks comments on the newly released draft of the Power Electronics and Development Program Planning Document.

“The electric grid is a complex system that has been built over the last century as demand for power has grown and now has more than 180,000 miles of transmission lines, 14,000 transmission substations, and more than 100 million distributed loads. There are over 3,000 electric utilities involved with the generation, transmission, and distribution of electricity. This system is the backbone of the nation’s economy, and it is imperative that the electric delivery system is modernized to meet the nation’s energy future...

To revolutionize the grid, power flow control and energy storage needs to be achieved—however, there are many barriers to realizing this vision. Advances in power electronics devices and modules, including materials development, high temperature packaging, and control systems are needed to increase their reliability and efficiency while at the same time decreasing their installation and operating costs.”
