“…Variable costs have traditionally been reported in cents/kWh, and ranged from 0.4-0.7 cents/kWh, where kWh is the cumulative energy out of the battery (Lamont 2004, Schoenung et al 1996. The variable O&M cost for NaS systems for various applications ranged from $2.6-13.4/kW-year (Gyuk and Eckroad 2003).…”

This report addresses several key questions in the broader discussion on the integration of renewable energy resources in the Pacific Northwest power grid. Specifically, it addresses the following questions: a) what will be the future balancing requirement to accommodate a simulated expansion of wind energy resources from 3.3 GW in 2008 to 14.4 GW in 2019 in the Northwest Power Pool (NWPP), and b) what are the most cost effective technological solutions for meeting the balancing requirements in the Northwest Power Pool (NWPP). A life-cycle analysis was performed to assess the least-cost technology option for meeting the new balancing requirement. The technologies considered in this study include conventional turbines (CT), sodium sulfur (NaS) batteries, Lithium Ion (Li-ion) batteries, pumped-hydro energy storage (PH), and demand response (DR). Hybrid concepts that combine 2 or more of the technologies above are also evaluated. The report also discusses the value of pumped hydro storage systems in the Bonneville Power Administration's footprint as an energy arbitrage instrument. This analysis was performed with collaboration by the Bonneville Power Administration and funded by the Energy Storage Systems Program of the U.S. Department of Energy. v SummaryStationary energy storage for power system application has recently attracted significant interest and attention as an enabling technology for integrating the growing capacity of variable renewable energy resources into the electric grid. Energy storage systems are likely to become an essential contributor to grid modernization investments that will transition the North American power system to a modern grid that meets the future needs under low carbon emissions constraints. In the Pacific Northwest as well as in other U.S. regions, the electricity production from wind technology has increased significantly to meet the renewable portfolio standards targets imposed by 24 U.S. States and the District of Columbia.For the Bonneville Power Administration (BPA) as the major grid operator in the Pacific Northwest, the growing wind generation poses some challenges to generation scheduling and the provision of ancillary services. To study the impacts of the variability in the wind generation on the regional grid operation and the role that energy storage may play to mitigate these grid impacts, Pacific Northwest National Laboratory (PNNL) collaborated with BPA to addresses the following key questions: c. Can energy storage be cost-effectively employed for arbitrage opportunities?Pacific Northwest National Laboratory applied a stochastic approach to assess the total balancing requirements for the NWPP for the high wind penetration in 2019. A simplifying assumption was applied that reduced the entire NWPP footprint into one single balancing area. With this assumption, the total balancing-up capacity requirements (generation increment) is approximately 3900 MW. The balancingdown capacity (generation decrement) is estimated to be about -3700 MW. These figures are based...

This report describes the results of a study on stationary energy storage technologies for a range of applications that were categorized according to storage duration (discharge time): long or short. The study was funded by the U.S. Department of Energy through the Energy Storage Systems Program. A wide variety of storage technologies were analyzed according to performance capabilities, cost projects, and readiness to serve these many applications, and the advantages and disadvantages of each are presented. AcknowledgmentThe author and Sandia National Laboratories wish to acknowledge the U.S. Department of Energy and specifically the Energy Storage Systems Program for support of this project. Some conclusions from this study include:− Flywheels are a good match for a range of shortterm applications up to a size of several MW. − Batteries currently have the broadest overall range of applications. − Fuel cells should be applicable and cost effective in a very broad range of applications in the future. − Hydrogen -fueled combustion engines are a currently available technology for short-term applications including distributed utility applications, renewables matching, and spinning reserve. − CAES and pumped hydro are best for load management when geology is available and response time in the order of minutes is acceptable. − SMES is a niche technology for power quality and especially high power distribution or transmission networks. Projected costs for bulk storage, however, show it to be expensive.
