Substation Expansion for Client Facilities

Schluter Systems received a substation expansion pricing package to support the energy needs of their new facility in Plattsburgh, NY.
The challenge lay in the opaque cost breakdown, clarity in design efficiency, equipment selection—particularly the 34.5kV extension from Kent Falls Substation—and system reliability under peak loads.
A thorough validation was needed to ensure alignment with long-term operational goals and to identify any overlooked cost-effective alternatives.

Conducted a detailed analysis of the substation expansion proposal, focusing on:

34.5kV feeder extension design and load-handling capacity.
Equipment specifications: transformers, breakers, capacitor banks, and switches.
System reliability under peak load and contingency conditions.
Assessed transformer loading profiles to validate operational efficiency.
Identified potential overdesign in protection and control schemes.
Provided a structured engineering review report with cost-optimization recommendations.

Identified cost savings through targeted design optimizations.
Recommended strategic adjustments in equipment selection (e.g., optimized breaker ratings, dual-secondary transformer configuration).
Improved system reliability and efficiency based on IEEE 1366 & NESC C2-2023 standards.
Provided technical validation to support informed decision- making.
Ensured infrastructure alignment with long-term operational and scalability requirements.
