What are the minimum requirements for an energy storage system (ESS) package?
This specification defines the minimum requirements for an Energy Storage System (ESS) Package which has Low Voltage (LV) primary output and is to be connected to a Horizon Power (HP) network or power station. This specification is relevant to the following ESS Packages: A Battery System or Energy Storage Medium. Power Conversion Equipment (PCE).
What is the design life of a battery system / energy storage medium?
The Design Life of the Battery System / Energy Storage Medium is the difference between the Beginning of Life (BOL) and the End of Life (EOL) of the Battery System. The Discharge Power of the ESS, measured at the Connection Point, accounting for all efficiency losses and parasitic loads.
What is an energy storage medium (ESS)?
ESS is a device or group of devices that is to convert electrical energy from power systems and store energy for later use when needed. An ESS is comprised of an Energy Storage Medium, a PCE, one or more enclosures housing the Energy Storage Medium and PCE, and an ESS Controller. The ESS Controller may be housed in an enclosure separate to the ESS.
