2018 U.S. Utility-Scale Photovoltaics-Plus-Energy Storage System Costs Benchmark
National Laboratory of the U.S. Department of Energy (NREL)
Ran Fu, Timothy Remo & Robert Margolis
The recent rapid growth of utility-scale photovoltaic (PV) deployment and the declining costs of energy storage technologies have stimulated interest in combining PV with energy storage to
provide dispatchable energy (i.e., energy on demand) and reliable capacity (i.e., grid stability). In particular, the use of lithium-ion batteries in U.S. utility-scale applications has grown in recent years owing to the technology’s favorable cost and performance characteristics.
This study is the authors' first time to use bottom-up modeling to benchmark the installed costs of various standalone lithium-ion storage (with storage connected to the grid only) and PV-plus-storage (with storage connected to PV and the grid) system configurations.
