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.
In conjunction with the DOE's Energy Storage Systems (ESS) program, the Clean Energy States Alliance hosted a webinar December 19, 2011, entitled "Energy Storage in State RPSs."
The webinar explored the role of energy storage in state RPS, including the integration of an increasing penetration of renewables and the interpretation of energy storage as a generation resource. The topics included a review of state RPS that include energy storage while exploring the benefits of energy storage to an RPS portfolio and the challenges of integrating storage into RPS programs.
Peer Review is open to the entire energy storage industry and provides a valuable networking opportunity for those in the industry and related fields. Reports will be presented on all projects supported by the DOE Energy Storage Program. Participants will be briefed on the latest developments in a broad portfolio of storage technologies (e.g., advanced batteries, flywheels, electrochemical capacitors, CAES) for utility-scale and standalone applications. The Program's latest research in power electronics and the results of analytical studies on the economic benefits of storage will also be presented.
This year's Peer Review will be held in conjunction with the bi-annual Electrical Energy Storage and Technologies Conference (EESAT 2011). Download the full Peer Review meeting agenda (250KB PDF).

The DOE/EPRI 2013 Electricity Storage Handbook in Collaboration with NRECA (PDF, 12 mb) has been released and is available for download. It was jointly authored by the Department of Energy's Sandia National Laboratories, Electric Power Research Institute, National Rural Electric Cooperative Association, and AECOM Technical Services, Inc.
The Electricity Storage Handbook is a how-to guide for utility and rural cooperative engineers, planners, and decision makers to plan and implement energy storage projects. The Handbook also serves as an information resource for investors and venture capitalists, providing the latest developments in technologies and tools to guide their evaluations of energy storage opportunities. It includes a comprehensive database of the cost of current storage systems in a wide variety of electric utility and customer services, along with interconnection schematics. A list of significant past and present energy storage projects is provided for a practical perspective.
Sandia National Laboratories' Electric Power Systems Research Dept. and Pacific Northwest National Laboratory's Advanced Power and Energy Systems Group have released a jointly authored report that examines how grid-level electricity storage might benefit the operations of NV Energy in 2020, and assesses whether those benefits justify the cost of the storage system.
Titled "NV Energy Electricity Storage Valuation" (PDF, 933 kb), the report finds that grid-level storage adds the most value to the 2020 NV Energy system by providing regulating reserve, and that a grid-level storage facility in the 2020 NV Energy system may have a positive net present value at today's storage system prices, provided that regulating reserve from a fast ramp rate resource is valued more than that from a slow ramp rate resource.
The Dept. of Energy's Energy Storage Program website has a number of updates that may be of interest to members the energy storage community.
The ES-Select™ Storage Selection Tool developed by DNV-KEMA has been updated recently, including enhancements in cash flow and payback analyses. Also, the DOE International Energy Storage Database provides free, up-to-date information on grid-connected energy storage projects and relevant state and federal policies.
On the ESS Program's Publications page, a number of recent SAND Reports have become available for download. The most-recent titles include Performance Testing of Zinc-Bromine Flow Batteries for Remote Telecom Sites (SAND2013-2818C), New Wholesale Power Market Design Using Linked Forward Markets (SAND2013-2789), and Southern Company Energy Storage Study (SAND2013-2251).
An improved version of the ES-Select™ Storage Selection Tool developed by DNV-KEMA is available for download. The new version includes a number of enhancements in cash flow and payback analyses as well as ease of use. Users are greeted with a newly structured homepage that simplifies the use process and identifies early on, feasible storage options for the user's selected applications before the user may need to have a further dive into specifics. Besides the strengthened business analysis capabilities, ES-Select™ now offers more flexibility for users to enter their storage data and adjust other storage option parameters like costs that are subject to change as technology costs come down.
First-time users need to download and run the ES-Select™ installer, which includes its supporting library. Once ES-Select™ is installed, the update installer then should be downloaded and run. If an earlier version of ES-Select™ is installed already, only the latest ES-Select™ update installer is needed.
The latest versions of the ES-Select Tool Installer and Updates has been released and are available from the ES-Select website, providing a variety of improvements in functionality and usability. Existing users of ES-Select only need to download and install the Update utility, while new users should download and install the main installation utility.
The ES-Select™ Tool aims to improve the understanding of different electrical energy storage technologies and their feasibility for intended applications in a simple, visually comparative form. It treats the uncertainties in technical and financial parameters as statistical distributions.
ES-Select™ was developed by DNV-KEMA in collaboration with Sandia National Laboratories, and is licensed for public use.
A number of reports have been publicly released by the Sandia National Laboratories' ESS Program. These are available at the ESS Program's Publications page. The most-recent titles include the following:
An improved version of the ES-Select Storage Selection Tool developed by DNV-KEMA is available for download. The new version includes enhanced cash flow and payback analyses, as well as improved ease of use. The new homepage simplifies the use process and immediately identifies feasible storage options for the selected application. In addition to the strengthened business analysis capabilities, ES-Select offers more flexibility for users to enter storage data and adjust other storage option parameters, including costs that are subject to change as technology costs come down.
The program's improved energy storage feasibility scoring algorithm better identifies applicable storage options for the selected application. A new algorithm for bundling multiple grid applications helps users understand the realizable potential and value for a storage system to serve multiple applications simultaneously. These enhancements simplify the analysis process of bundled services and enable users who are unfamiliar with energy storage to evaluate a bundled business case.
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 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."
A beta version of the online DOE Energy Storage Database has been released for public use, providing free, up-to-date information on grid-connected energy storage projects and relevant state and federal policies.
Projects and policies can be searched based on a number of criteria, including power rating, ownership model, and grid interconnection. The information from the database can be exported to Excel or PDF.
All project and policy information in the database is vetted through third-party verification. The database was developed to contribute to the rapid development and deployment of energy storage technologies.
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.

ESS researcher Stan Atcitty was named a recipient of one of R&D Magazine's R&D100 Awards for 2011. The awards are presented to researchers who have been determined, by a selecting council, to have developed the year's top 100 outstanding achievements in applied technology. They focus on applied impact and reward awardees based on product design, development, testing, production, and applicability. Sandia National Labs won four such awards this year.
Stan Atcitty won for his entry on an Ultra-high-voltage Silicon Carbide Thyristor. This DOE Energy Storage Systems project, managed by Sandia in partnership with GeneSiC Semiconductor Inc., and the U.S. Army Armament Research, Development and Engineering Center (ARDEC), developed an ultra-high-voltage silicon carbide thyristor. The semiconductor device allows next-generation "smart grid" power electronics system to be built up to 10 times smaller and lighter than current silicon-based technologies. Their performance advantages are expected to spur innovations in utility-scale power electronics hardware and to increase the accessibility and use of distributed energy resources.
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.”
