5.1 Potential New Facilities As of late June 2010, NSPI's interconnection request queue includes 1,382 MW of proposed generation projects at various stages of interconnection study. Sponsors of these projects have requested either Network...

AI summary As of late June 2010, NSPI has 1,382 MW of proposed generation projects in its interconnection request queue, with sponsors requesting either Network Resource Interconnection Service (NRIS) or Energy Resource Interconnection Service (ERIS). These requests involve firm capacity and potential transmission reinforcement.

ERIS - Energy Resource Interconnection Service NRIS - Network Resource Interconnection Service N/A - Not Applicable Included in this interconnection queue is 165 MW of wind energy projects which are part of NSPI's Renewable Energy Standard...

AI summary The interconnection queue includes 165 MW of wind energy projects under NSPI's RES commitment, along with other projects at various stages of development. Table 7 provides details on the locations and sizes of these planned generating facilities.

6.1 Operating Reserve Criteria As a member of the Maritimes Area of the Northeast Power Coordinating Council (NPCC), NSPI meets the operating reserve requirements as outlined in NPCC Document A-6, Operating Reserve Criteria . This criteria...

AI summary NSPI adheres to NPCC's operating reserve criteria, sharing ten-minute reserves with NBSO via a load-ratio share and maintaining 171 MW of ten-minute reserves. It anticipates increased regulating reserves due to wind generation and conducts biannual 18-month resource adequacy assessments. The Interconnection Agreement outlines shared reserve responsibilities.

7.2 Transmission Design Criteria NSPI, consistent with good utility practice, utilizes a set of deterministic criteria for its interconnected transmission system that combines protection performance specifications with system dynamics and...

AI summary NSPI employs deterministic criteria for transmission system design, ensuring reliability through single contingency standards and Special Protection Systems (SPS). It adheres to NPCC guidelines for interconnected systems and leverages SPS within SCADA to manage stability and prevent overloads.

7.5 NSPI/NB Interconnection Overview The power systems of Nova Scotia and New Brunswick are interconnected via three overhead transmission lines; one 345kV line from Onslow, Nova Scotia to Memramcook, New Brunswick, and two 138kV lines fro...

AI summary Nova Scotia and New Brunswick's power systems are interconnected via three transmission lines, with the 345kV line carrying 80% of total power. The interconnection ensures system reliability, with import/export limits set at 350MW export and 300MW import to manage single contingency losses. Flow on 138kV lines is influenced by regional loads.

Export Import Number of thermal units armed for NS system load level (Import less than generation rejection (maximum two) 22% of total system load) Reactive Power Support level in the Halifax Regional Municipality Percentage of dispatchabl...

AI summary The document discusses the potential risks to the NSPI system if it becomes separated from New Brunswick during export, leading to increased system frequency. To mitigate this, NSPI employs fast-acting Special Protection Systems to reject generation and stabilize the system.

1. 2010 - Work will begin on the construction of additional transmission to the Western Valley area. This will include the construction of a 138 kV circuit between Canaan Road and Tremont, a 138 kV termination at Canaan Road and the additi...

AI summary The 2010 document outlines transmission infrastructure upgrades, including new 138 kV circuits, transformer installations, and reliability improvements. Projects aim to prevent outages, replace aging equipment, and integrate renewable energy sources like wind farms. Key initiatives include insulator replacement, switchgear upgrades, and grid expansions to enhance system reliability and accommodate renewable generation.

f) Cape Breton Wind generation (150MW -250MW) development scenario An existing 230 kV circuit would be uprated to 345 kV to provide a 345 kV transmission connection between Onslow and Brushy Hill and reactive power compensation would be in...

AI summary The Cape Breton Wind generation scenario outlines infrastructure upgrades including uprating a 230 kV circuit to 345 kV, establishing new 345 kV substations at Port Hastings and Spider Lake, constructing 345 kV transmission lines to Woodbine and Spider Lake, a new Canso crossing, and adding 100 MVAR reactive compensation in the Dartmouth area.

b) Metro Large Natural Gas Generator Scenario Development of a 138 kV substation at Spider Lake to terminate two existing Dartmouth 138 kV circuits along with increasing the conductor size on two existing Dartmouth circuits. A new 138 kV c...

AI summary The Metro Large Natural Gas Generator Scenario outlines infrastructure upgrades including a new 138 kV substation at Spider Lake, conductor size increases on Dartmouth circuits, new 138 kV circuits to Sackville, and a high-capacity line between Tufts Cove and Brushy Hill, alongside substation modifications at Tufts Cove and Brushy Hill.
