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
