StorageTechnology

Package: PowerInvestmentsOpenAPIModels · Source: Investments/Technologies/StorageTechnology.json

Candidate storage technology in a region. Charge capacity, discharge capacity, and energy capacity are added independently, each with its own capital cost, unit size, and capacity limits; charge and discharge efficiency, self-discharge losses, and limits on the ratio of energy to discharge capacity complete the description.

Properties

Property	Type	Required	Unit	Description
