Feature Batteries: An Integrated Solution Jennifer A. Eirich, Marketing Manager,ODYSSEY Battery, Specialty and Rail, EnerSys George Brendahl, Marketing Manager, Utility and Nuclear, EnerSys According to the US Department of Energy (DOE), growth in peak demand for electricity in the US has exceeded transmission growth by almost 25 percent every year since 1982.1 Today's utilities are now being challenged to manage increasing consumption with an aging and already compromised infrastructure, congested transmission lines and greater reliance on renewable resources. The US Energy Information Administration (EIA) states 51 percent of all generating capacity (530 GW) is at least 30 years old.2 This is especially surprising when compared to the telecom industry. For example, just think of the strides that have been made in telecommunications in the past three decades, from portable and cellular technology to smart phones, tablets and more. Meanwhile, with hundreds of thousands of high-voltage transmission lines connecting the US, only 668 additional miles of interstate transmission have been built since year 2000.1 At the same time, utilities are struggling to incorporate new, renewable sources of energy. According to the EIA, renewable energy will account for about one-third of new electricity generation added to the US grid over the next three years. Yet, despite all of these challenges, spending on research and development is among the lowest of all industries. The result is power outages and interruptions that cost American businesses more than $100 billion each year. Even single incidences can have a significant impact.1 Energy storage works to address these power concerns, especially those striving to incorporate renewable energy sources. Energy is a "just-in-time asset" where generation must be matched to the demand in order to maintain reliability and stability. Wind and sun are intermittent by nature, leaving gaps in the utility's ability to provide constant power. Energy storage helps to bridge this gap by allowing energy to be stored for those times when it is in greatest demand. Energy storage not only helps to prevent service interruptions and downtime, but it also allows for distributed service, placing the energy source closer to the process and equipment that will use it. It also helps utilities postpone and possibly avoid costly expansions or upgrades as demand grows and renewable generation increases. The Role of Energy Storage Increasingly, energy storage is being regarded as a way to balance the grid. The Energy Storage Association (ESA), has stated that energy storage can "ease the market introduction of renewables, accelerate the decarbonization of the electricity grid, improve the security and efficiency of electric transmission and distribution (reduce unplanned loop flows, grid congestion, voltage and frequency), stabilize market prices for electricity, while also ensuring a higher security of energy supply.3 Electric utilities already are among the largest owners and users of electrochemical battery systems,4 and the global energy storage market is expected to grow 71 percent per year in terms of capacity from 2014 to 2023, according to a recent study by Navigant Research.5 This increased demand for grid-scale storage has opened the door for many new technologies as suppliers compete to fill this need. Utilities must weigh their options carefully to find the optimum solution. Often, traditional technologies offer the most sensible solution. As energy demand continues to increase, today's utility leaders need to find the right solution and the right partner. Matching the Right Solution to Your Application While some forecasters assume that the growth in energy storage will be in newer energy storage technologies, the Electric Power Research Institute (EPRI) holds that "no single storage system can meet all of the application needs of the power grid, and a wide variety of storage technology options are being proposed for utility-scale storage uses."6 The key is matching the application with the right storage solution. To do this, the utility must develop a clear profile of the application by addressing several key decision-making factors. 6 Battery Power * Spring 2015
