About Essex Transmission
Essex Transmission LP is building an enhanced regional power system designed to deliver reliable, scalable, and cost-effective energy infrastructure. Our innovative model brings together Local Distribution Companies (LDCs), licensed transmission partners, and private equity investors to accelerate the development of critical power infrastructure faster and more affordably than traditional approaches.
By strengthening the regional grid, Essex Transmission is enabling long-term growth across the Essex region. Our infrastructure will support greenhouse growers, agricultural operations, and other energy-intensive industries that are essential to food production, economic development, and local employment.
Through strategic partnerships and private investment, we are connecting power to opportunity ensuring the region has the reliable energy foundation needed to grow, compete, and feed communities for generations to come.

Essex Transmission is initiating the Screening Process under the Class Environmental Assessment for Transmission Facilities (Class EA for TF) to support long-term electricity demand in the Windsor-Essex region, which is experiencing significant pressure related to expansion across the greenhouse, agri-food, automotive/electric vehicle, and advanced manufacturing sectors. Existing 27.6 kV infrastructure is currently operating under constrained conditions, limiting new customer connections and restricting broader economic development.
To address these challenges, Essex Power Transmission is proposing new transmission infrastructure that will increase system capacity and improve reliability.
230 kV Transmission Components including two new 230 kV transformer stations (TS-1A and TS-1B) connected by 230 kV transmission lines to Lakeshore TS to create network hubs, details as follow:
-
One new transformer station called TS-1A located west of Highway 77 and Mersea Road 10
-
One new 230 kV double-circuit line extending approximately 6.5 km south from the existing Hydro One Lakeshore transformer station (southeast of County Road 46 and Rochester Townline Road) to the TS-1A transformer station.
-
One new transformer station called TS-1B located south of Country Road 8 and east of Highway 77.
-
One new 230 kV double-circuit line extending approximately 6.3 km south from the existing Hydro One Lakeshore transformer station to the TS-1B transformer station.
Additional Transmission Network – additional facilities required to connect TS-1A to customer load centers including:
-
New 115 kV or 230 kV transmission circuits running south approximately 9.6 km from TS-1A to a proposed transmission station located north of Country Road 18 and east of Albuna Townline.
-
Transmission line taps located on private properties to connect new 115 kV or 230 kV transmission circuits to agricultural facilities.
-
New 115 kV or 230 kV transmission circuits running east approximately 3 km from proposed transmission station to an additional transmission station located North of Mersea Road 5 and east of Highway 77.
-
Additional transmission facilities to connect TS-1B to customer load centres will be developed in a later project phase to support regional growth, improve system flexibility, and maintain long-term reliability. Routing alternatives were assessed to identify technically feasible corridors while minimizing conflicts with existing Hydro One infrastructure, sensitive environmental features, and nearby residential and agricultural lands.
