SCHEDULE 3-DISTRIBUTED ENERGY RESOURCES INTERCONNECTION PROCESS 3.3. Simplified Process An application to interconnect a certified', inverter-based DER system no larger than 20 kilowatts (kW) shall be evaluated under the Simplified Process. A common form of DER inverter certification is UL 1741. Proposed DER systems that require Area EPS system modifications to accommodate the interconnection do not qualify for the Simplified Process. A transformer change, fusing upgrades or line extensions are common examples of Area EPS system modification. Simplified Process eligibility does not imply or indicate the Interconnection Application will pass the initial review screens. Failure to pass the screens will route the Interconnection Application to the Fast Track Process. 3.4. Fast Track Process An application to interconnect a DER shall be evaluated under the Fast Track Process if the eligibility requirements are not exceeded in Table 3.2 and the application does not qualify for the Simplified Process. Fast Track eligibility for DERs is determined based upon the generator type, the size of the generator, voltage of the line, and the location and type of line at the Point of Common Coupling, (PCC). All synchronous and induction machines must be no larger than 2 MW to be eligible for Fast Track Process consideration. Table 3.2.

'Additional information regarding certified equipment is found in Sections 14 and 15. 2 Synchronous and induction machine eligibility is limited to no more than 2 MW even when line voltage is greater than 15 kV. 3 For purposes of this table,a Mainline is the three-phase backbone of a circuit. It will typically constitute lines with wire sizes of 4/0 American wire gauge,266 kcmil, 336.4 kcmil, 397.5 kcmil,477 kcmil and 795 kcmil. 4 An Interconnection Customer can determine this information about its proposed interconnection location in advance by requesting a pre-application report described in Section 5. 5 140
