Technology and asset parameters

Technical concepts that define the performance, limitations, degradation and operating profile of an energy asset.

Augmentation

Augmentation means adding or replacing battery capacity over time to maintain the required usable capacity or performance.

Battery chemistry describes the electrochemical technology of the cells and its impact on performance, degradation, safety and cost.

Co-location means placing an energy storage asset together with another generation source, such as PV or wind, at one site or connection point.

Battery degradation is the gradual loss of battery capacity and performance resulting from use, time and operating conditions.

FEC, or Full Equivalent Cycle, is a measure of battery use expressed as equivalent full charge and discharge cycles.

LTSA, or Long-Term Service Agreement, is a long-term service contract covering maintenance, performance obligations and support for an asset.

A performance warranty is a contractual commitment that the asset will maintain defined performance parameters over time.

RTE, or Round-Trip Efficiency, measures how much energy is discharged compared with the energy charged into the storage system.

SoH, or State of Health, describes the technical condition of a battery compared with its original capacity or performance.

Throughput is the total amount of energy charged into or discharged from a battery over a defined period.
