a) Line 15 Protection Packages 6-1 SERVICE AGREEMENT NO. 2720 The existing Line 15 protection is a POTT for the ‘A’ package and step distance for the ‘B’ package. The existing A package relay is a SEL-321 and will be reused and reset to accommodate the generation. However, the existing B package relay is a SEL-221 which cannot be reset to accommodate the generation and will be replaced with an ERLPhase LPro. DTT transmit and receive to the Xxxxx Solar Collector Station will be added. DTT will be sent to the Xxxxx Solar Collector Station for a line relay operation and R15 breaker failure. DTT for breaker failure will be received from the Xxxxx Solar Collector Station. The ‘A’ package line relay will be used for DTT receive supervision and will be used to trip and drive reclosing to lockout. The existing electromechanical reclosing relays shall be replaced with one (1) SEL351 6 relay to allow addition of drive to lockout (“DTL”) for DTT receive. A GARD8000 will be added for DTT to and from the Xxxxx Solar Collector Station.
Mohican Substation. All modifications shall be completed in the Mohican Substation yard and control house. The Connecting Transmission Owner’s Mohican rebuild firm project underway is expected to be complete prior to the In-Service Date for the Small Generating Facility. The SUFs identified in this section, assume that the rebuild has been completed. At the time the facilities study was performed, there is adequate space in the control enclosure to accommodate the additional facilities required for to accommodate the interconnection of the Small Generating Facility.

a) Protection The existing Line 15 ‘A’ package is a permissive overreaching transfer trip (“POTT”) scheme using an ABB RED670 relay and the ‘B’ package is step distance using a GE-L90 relay. Both ‘A’ and ‘B’ packages will be reused and reset to accommodate the Small Generating Facility. DTT transmit and receive will be added to the Xxxxxx Solar Collector Substation, which will require the addition of one (1) RFL GARDPro (or Connecting Transmission Owner approved equivalent). DTT will be sent to the Xxxxxx Solar Collector Substation for a line relay operation or R15 breaker failure and DTT for breaker failure will be received from the Xxxxxx Solar Collector Substation.
