Export requirements for energy storage equipment

cient and effective interconnection process for ESS. Energy storage export and import can provide beneficial service to the end-use customer as well as the electric grid. These capabilities can, for example, balance power flows within system hosting capacity limits, reduce grid operational costs, and enable a

import limits within distribution system constraints. Storage could also use PCS to enable it to comply with net energy metering requirements, typically when set for export only to ensure that a battery is charged entirely from solar or import only t

Export4.10.4.3.1 Certified Power Control SystemsDER m y use certified Power Control Systems to limit export. DER utilizing this option must use a Power Control System and inverter certified per UL 1741 by a nationally recognized testing laboratory (NRTL) with a maximum open loop response time

Export ControlsA. Introduction and Problem StatementStorage systems have unique capabilities, such as the bility to control export to, or import from, the grid. There are multiple different methods by which ESS can manage export, including the use of traditional relays as well as Power Control Systems t

via configuration (known as Configured Power Rating). This optional feature can be tested with the IEEE 1547.1-2020 test procedures.30 While limiting power via configuration settings does limit export power, it would also generally limit the ability to serve any onsite load when this limit affects the power
