## 400 MVA Substation Expansion for Industrial Electrification

The Chatham-to-Lakeshore corridor represents a critical pillar of the Independent Electricity System Operator’s (IESO) regional grid expansion in Southwestern Ontario. The project introduces two new 230/115 kV 200 MVA power transformers at the Lakeshore Transformer Station, expanding local step-down capability.

The installation incorporates advanced 230 kV sulfur-hexafluoride-insulated breakers, optical ground wire (OPGW) differential protection relaying, and acoustic noise enclosures tailored to proximity with surrounding agricultural communities.

## Meeting Exponential Industrial Power Demand by Late 2027

Regional electricity demand in Windsor-Essex is projected to quadruple by 2030, driven by automotive battery gigafactories and indoor automated vertical farming facilities.

Hydro One’s fast-tracked schedule targets energization of the first 230 kV circuit by the third quarter of 2027, establishing high-reliability power corridors backed by modern digital SCADA infrastructure.
