DAYS* program overview
Objective
Develop innovative technologies to enable
energy storage on the power grid with durations
of 10-100 hours
Performance Targets
‣ Levelized cost of storage of $0.05/kWh-cycle
‣ No siting constraints

Primarily technology-dependent parameters
• ηRTE – round-trip efficiency of storage (AC basis)
• ηD – discharge efficiency of storage (AC basis)
• O&M – fixed and variable operations and maintenance
cost (including component replacements)
• CE – installed marginal capital cost of energy in $/kWh
• CP – installed marginal capital cost of power in $/kW
Primarily application-dependent parameters
• PC – input electricity price in $/kWh
• d – duration of storage at rated power in hours
• nC – number of equivalent full cycles

Long-duration technologies and applications
Applications
‣ Provide extended backup power for
critical loads
‣ Optimize utilization of transmission
and distribution infrastructure
‣ Improve reliability and resiliency of
high-VRE grids
‣ Increase capacity value as VRE
and storage penetrations increase
