PSC 119.02 (5) “Category 2” means a DG facility with an export capacity of greater than 20 kW and not more than 200 kW. The nameplate rating shall be used instead of the export capacity for this definition if the non-exporting energy storage system is larger than 20 kW.
Section 3. PSC 119.02 (6) is amended to read:
PSC 119.02 (6) “Category 3” means a DG facility with an export capacity of greater than 200 kW and not more than 1 MW. The nameplate rating shall be used instead of the export capacity for this definition if the non-exporting energy storage system is larger than 200 kW.

PSC 119.02 (16d) “Energy storage system” means a device or devices that capture energy produced at one time, store that energy for a period of time, and deliver that energy as electricity for use at a future time.
Section 6. PSC 119.02 (16h) and (Note) are created to read:
PSC 119.02 (16h) “Energy storage system max continuous output kW in alternating current” means the maximum rated continuous power output of the energy storage system.
PSC 119.02 (16h) (Note): This defined term should be used when completing the standard application form, PSC Form 6031.
Section 7. PSC 119.02 (16p) and (Note) are created to read:
PSC 119.02 (16p) “Energy storage system max usable energy kWh in alternating current” means the maximum rated amount of energy stored in the energy storage system.
PSC 119.02 (16p) (Note): This defined term should be used when completing the standard application form, PSC Form 6031.
Section 8. PSC 119.02 (16t) and (Note) are created to read:
PSC 119.02 (16t) “Energy storage system peak output kW in alternating current” means while grid interactive, the maximum short duration rated output power of the energy storage system to the distribution system.
PSC 119.02 (16t) (Note): This defined term should be used when completing the standard application form, PSC Form 6031.
Section 9. PSC 119.02 (17m) is created to read:
PSC 119.02 (17m) “Export capacity kW in alternating current” means the amount of power that can be transferred from the DG facility to the distribution system. Export capacity is the lesser of the following:
(1)
the nameplate rating.(2)
if limited using any approved means, that limited amount.Section 10. PSC 119.02 (25) is amended to read:
PSC 119.02 (25) “kW” means kilowatt. Unless otherwise specified, the definition references units in alternating current.
Section 11. PSC 119.02 (27) is amended to read:
PSC 119.02 (27) “MW” means megawatt. Unless otherwise specified, the definition references units in alternating current.
Section 12. PSC 119.02 (27m) is created to read:
PSC 119.02 (27m) “Nameplate rating alternating current” means the sum total of maximum continuous rated power (kW) output while grid connected of all of a DG facility’s constituent generating units or energy storage systems, or both, as identified on the manufacturer nameplate, regardless of whether it is limited by any approved means.
Section 13. PSC 119.02 (32) is amended to read:
PSC 119.02 (32) “Point of common coupling” means the point where the electrical conductors of the distribution system are connected to the customer’s conductors and where any transfer of electric power between the customer and the distribution system takes place power system of the applicant seeking to interconnect a DG facility is electrically connected to the distribution system. The point of common coupling is equivalent, in most cases, to the service point as specified by the public utility and described in the National Electric Code and National Electrical Safety Code.
