  • Evaluating the Technical and Economic Performance of PV Plus Storage Power Plants by National Renewable Energy Laboratory

    Posted: August 31, 2017 - 11:20 / NREL / Reports

    The decreasing costs of both PV and energy storage technologies have raised interest in the creation of combined “PV plus storage” power plants. In this study, we examine the tradeoffs among various PV plus storage configurations and discuss an approach to quantify the impact of configuration on system net value.

  • Estimating the Value of Utility-Scale Solar Technologies in California Under a 40% Renewable Portfolio Standard

    Posted: June 11, 2014 - 01:02 / NREL / Reports

    With growing interest in renewable energy, the penetration of solar photovoltaics (PV) and wind generation is likely to rise. Accommodating the time-varying and uncertain output of these resources will be a challenging aspect of integrating large-scale renewable energy into the electric power system. Concentrating solar power (CSP) with thermal energy storage (TES) is a unique source of solar energy in that its output can be shifted over time and also controlled in response to system operator signals, allowing for provision of a wide range of grid services. The ability of CSP-TES to be a flexible source of renewable generation may be particularly valuable in regions with high overall penetration of solar energy, such as the state of California.

  • Active Power Controls from Wind Power: Bridging the Gaps

    NREL's Energy Storage Project is leading the charge on battery thermal management, modeling, and systems solutions to enhance the performance of fuel cell, hybrid electric, and electric vehicles (FCVs, HEVs, and EVs) for a cleaner, more secure transportation future. NREL's experts work closely with the U.S. Department of Energy (DOE), industry, and automotive manufacturers to improve energy storage devices, such as battery modules and ultracapacitors, by enhancing their thermal performance and life-cycle cost. Activities also involve modeling and simulation to evaluate technical targets and energy storage parameters, and investigating combinations of energy storage systems to increase vehicle efficiency.
