Notices

Please be advised of the following notices.

Due to the ongoing COVID-19 pandemic response there may be delays in processing physical copies of documentation. Please use the contact details above for the Interconnection Engineer to determine suitable submission arrangements.

Due to ongoing development discussions and engineering studies, the Transmission System Network Upgrades identified as part of Transmission Service Request #411 will not be included in the System Impact Study (SIS) Analysis for Generator Interconnection Procedures (GIP) Study Groups #32 and #33. GIP Study Group #32 and #33 analysis will be limited to the 2022 Transmission System configuration plus any material Network Upgrades identified in higher queued projects.

Due to the expected increase in inverter-based generation resources in Nova Scotia and the anticipated decrease in synchronous generation related to the requirement to phase-out of coal fired generation by 2030, GIP System Impact Study analyses are being expanded to include Electromagnetic Transient (EMT) Analysis in addition to Load Flow and Dynamic Analysis. To accommodate this change, Interconnection Customers are required to provide the System Operator with the appropriate PSCADTM models for their generators in addition to the PSS®E generator models required in the Generator Interconnection Procedures. A separate report will be issued for the Electromagnetic Transient Analysis.

Section 7.6.7 of the Transmission System Interconnection Requirement (TSIR) is currently under review. The review outcome will be posted on OASIS at a later date.
