  1. Energy storage technologies: Transforming America’s Intelligent Electrical Infrastructure Turner Cotterman Clemson University IEEE, WISE Intern 31 July 2013

  2. In This Presentation • Background of energy issues • Complexity of our nation’s system • Relevant legislation • What is energy storage? • Advantages of storage • Types of storage • Conclusions • Policy recommendations

  3. Background • Issues • Global populations are increasing • Nonrenewable energy resources (e.g. coal, oil, natural gas) are being used up • Growing demand for energy (digitization) • Climate change occurring at an alarming rate • Approaching energy crisis? • Solutions • Shift dependence to renewable energy resources (e.g. wind, solar, hydropower) • Reinvent lifestyles and technologies to be more efficient • Improve and strengthen our electrical infrastructure • Energy storage technologies will have a strong part to play

  4. Complexity of Current U.S. Electrical Grid Source: FEMA

  5. Legislation • Energy Independence and Security Act (2007) • Awareness of storage technologies, electricity infrastructure • American Recovery and Reinvestment Act (2009) • Funding, further awareness • FERC: Orders 890, 755 • California AB 2514 (2010) • One of the first state examples • STORAGE Act (2013)

  6. Overview of Energy Storage • Technology to store generated electricity in order to perform useful operation at a later time • Supportive of generation systems • Increases adoption & profitability of renewable energy • Energy storage can: • Improve efficiency of existing systems • Defer costly upgrades to transmission/distribution infrastructure • Helps utilities meet peak load demands • Supports the smart grid • Provides resiliency to the grid • Energy reserves for natural disasters, power outages

  7. Traditional Power System Source: Eos Energy Storage

  8. Wind and Solar Generation • Without smoothing abilities, fluctuations could pose serious problems for dependable power needs Source: CAISO

  16. Conclusions • Choosing specific energy storage system is both location- and application-specific • Cost is major prohibitive consideration in implementation of these systems • Combination of government assistance, private industry involvement, public support

  17. Policy recommendations • Pass pending federal legislation and develop state-level proposals for energy storage • Federal and state governments must use their abilities to encourage financial investment by private industry • Streamline and simplify regulatory requirements for energy storage developments • Increase public awareness of the need to adopt energy storage and smart grid technologies • Continue to advance private and public research of storage technologies • Promote the development and implementation of international standards for energy storage
