AI summary A redacted table entry referencing '92H-331 Double Circuit Peggy's Cove Rd.' with a date of March 13, 2026 and reference number CI C0080102. The content is heavily redacted, limiting details about the proceeding or matter.
5.1.1 92H Transformer Overload The transformer 92H‑T61 would have recorded a peak load of 20.5 MVA in 2025 without embedded hydro generation, exceeding 164% of its 12.5 MVA top nameplate rating. Historical loading on this transformer has i...
AI summary Transformer 92H-T61 is overloaded, exceeding 164% of its 12.5 MVA rating without hydro generation. Winter peaks surpass planning criteria, and mobile transformers installed in 2026 are not viable long-term solutions. Hydro generation was used in 2025 but is unreliable due to drought, necessitating permanent corrective action.
Scope of this alternative: - Construct a new feeder at 131H Lucasville. - Extend the new feeder 13.3 km from Lucasville to Stillwater Lake. - Build a second additional feeder from Lucasville and extend 1.8 km to Bryanston Road to provide c...
AI summary The proposed alternative involves constructing and extending new power feeders, transferring lines between circuits, and building a new substation in Stillwater Lake by 2029 to improve grid reliability and capacity.
7.4.1 Hammonds Plains Alternative A: Stillwater Lake Substation Construction of a new substation in the Stillwater Lake area provides the most effective solution for the identified capacity concerns. This alternative introduces a new distr...
AI summary Construction of a new Stillwater Lake substation addresses capacity concerns by reducing feeder lengths, improving voltage performance, and lowering outage risks. It transfers load from existing feeders, reduces transformer loading, and accommodates future growth with low capital costs and existing land acquisition. This alternative is deemed the preferred solution due to its efficiency and long-term viability.
8.0 RECOMMENDATIONS This study identified immediate and long-term capacity constraints affecting the 92H-Tidewater and 137H-Hammonds Plains substations. These include transformer overloads, feeder loading violations, voltage concerns, and...
AI summary The study recommends immediate upgrades to 92H-Tidewater and 137H-Hammonds Plains substations to address transformer overloads, feeder loading violations, and insufficient contingency capacity. Immediate actions include replacing transformers, constructing new feeders, and building the Stillwater Lake substation. Long-term plans involve voltage upgrades and future substation expansions by 2037.
Tidewater and Hammonds Plains Area Review Proposed T Proposed Tidewater Area Area/Planning Study Metro Regio n POWER An Emera Company Prep. By: BH June 28, 2024 1 Page 1 of 2 An Emera Company Project The purpose of this purpose of this pur...
AI summary The document discusses a planning study for the Tidewater and Hammonds Plains area, highlighting the need for infrastructure upgrades due to transformer overloading and insufficient capacity. Key issues include the transformer 92H-T61 reaching 170% loading, overloaded feeders, and the need for a new 25 kV source to address long-term capacity needs.
NON-CONFIDENTIAL The typical planning limit for distribution feeders is 325 A, unless a lower limit applies due to feeder-specific thermal or protection-coordination constraints. This planning limit is intended to keep standard equipment w...
AI summary The text discusses distribution feeder planning limits (325A), SCADA upgrades planned for 2026, and overload issues on feeder 92H-331. NS Power addresses customer complaints about power quality through feeder balancing and regulator repairs, citing a specific Board file (M12730). Overloads occur during winter peak loads, prompting infrastructure improvements.
NON-CONFIDENTIAL 1 Request IR-11: 28 system to the coastal area and to transfer the growing Hubley load to a new 25 kV source 29 from Stillwater Lake. The Hubley portion of 92H-332 is therefore the portion identified for 30 conversion and...
AI summary The text discusses the conversion of the 92H-332 system to address capacity issues, noting that a full conversion would be costly and impractical. It highlights the need for upstream 25 kV capacity and mentions the approximate cost of a full conversion as exceeding $22.5 million.
