When finished, the smooth concrete lining will allow for the uninterrupted flow of Niagara River water through the 10.2km tunnel to the Sir Adam Beck generating stations for the next 100 years.
Tunnel excavation, using the world’s largest hard-rock TBM, was completed last spring. When finished in 2013, the Niagara Tunnel – one of the largest renewable energy projects of its kind – will supply enough clean, renewable electricity to power 160,000 homes.
The project currently employs more than 400 people and has brought about $1B in economic benefits to the region.
Strengthening Ontario’s hydroelectric infrastructure is an important part of the Ontario Government’s plan to build a modern, clean, reliable electricity system to power homes, schools, hospitals and the economy.
