“…A wide range of costs has been reported for redox flow batteries, with unit costs varying based on the power to energy ratio (Eckroad 2007;Gyuk 2003;Corey 2002). A comprehensive review of the vanadium redox flow battery systems deployment and cost analysis was recently published (Kear et al 2011).…”

PHASE I WECC PHASE II EIC + ERCOT v 2. What are the most cost-effective technology options for providing additional balancing requirements today and in 2020 assuming technological progress? Our analysis includes the following technologies: i. Combustion turbine as a base case technology ii. Na-S (Sodium Sulfur) batteries iii. Li-ion (Lithium-ion batteries) iv. Flywheel v. CAES (Compressed Air Energy Storage) vi. Redox Flow batteries vii. Pumped Hydroelectric (PHES) Storage viii. Demand Response ix. Hybrid energy storage systems (configurations of various above mentioned storage technologies) 3. What is the market size (quantified in MW and MWh) for energy storage and its respective cost targets (expressed in $/kWh) for balancing and energy arbitrage applications by regions? Key Outcomes Pacific Northwest National Laboratory (PNNL) analyzed a hypothetical 2020 grid scenario in which additional wind power is assumed to be built to meet WECC's 20% renewable energy portfolio standard target. Several models were used to address the three questions, including a stochastic model for estimating the balancing requirements using current and future wind statistics and the statistics of forecasting errors. A detailed engineering model was used to analyze the dispatch of energy storage and fast-ramping generation devices for estimating capacity requirements of energy storage and generation that meet the new balancing requirements. Financial models estimated the life-cycle cost (LCC) of storage and generation systems and included optimal sizing of energy storage and generation to minimize LCC. Finally, a complex utility-grade production cost model was used to perform security constrained unit commitment and optimal power flow for the WECC. Outcome 1: Total Balancing Market in the WECC is Estimated to be 6.32 GW Assuming about 24 GW of Installed Wind Capacity in 2020 The total amount of power capacity for a 20% RPS scenario in the WECC for 2020 would require a total intra-hour balancing capacity of approximately ~6.32 GW. The total market size was estimated for the WECC by NERC sub-regions based on the potential for energy storage in the high-value balancing market. The energy capacity, if provided by energy storage, would be approximately 2.0 GWh, or a storage that could provide power at rated capacity for about 20 minutes. The additional intra-hour balancing capacity that is required to accommodate the variability due to capacity addition in wind technology and load growth from 2011-2020 was estimated to be 1.53 GW. If these additional balancing services were provided by new energy storage technology, the energy capacity would be about 0.58 GWh, or a storage capable of providing electricity at the rated power capacity for about 20 minutes. vi The regional distribution of balancing requirements within the WECC is driven by load forecasting wind prediction errors. Because of the non-homogeneous distribution of the loads and wind across the WECC region, the balancing requirements increase with load and wind capacity. NWPP and Ca...

This report extends an earlier characterization of long-duration and short-duration energy storage technologies to include life-cycle cost analysis. Energy storage technologies were examined for three application categories-bulk energy storage, distributed generation, and power quality-with significant variations in discharge time and storage capacity. More than 20 different technologies were considered and figures of merit were investigated including capital cost, operation and maintenance, efficiency, parasitic losses, and replacement costs. Results are presented in terms of levelized annual cost, $/kW-yr. The cost of delivered energy, cents/kWh, is also presented for some cases. The major study variable was the duration of storage available for discharge.

“…Hence, attention is now focused on more advanced systems, sodium/sulfur, zinc/bromine, vanadium flow batteries and the Regenesys flow battery (polysulfide/bromine) and such technology has been piloted on a scale ranging from 100 kW to several MW. 3,4 The flow batteries do not yet have all the performance requirements nor meet their cost targets but scale-up is much less an issue than with the traditional batteries.…”
