Entegrus Transmission Inc. (“ETI”), a wholly owned subsidiary of Entegrus Inc., was licenced by the Ontario Energy Board as a transmission company on May 26th, 2011 becoming one of Ontario’s seven licenced transmitters.  

Since incorporation ETI has been dedicated to the development and connection of renewable energy generation in Ontario and improving the overall reliability, safety and cost-effectiveness of electrical transmission in this province.

As part of our commitment to support the Province of Ontario’s 2013 Long Term Energy Plan : Achieving Balance, ETI has invested over $10 million in transmission related assets to enable renewable energy generation in Southwestern Ontario.  ETI’s success has been based on establishing large-scale partnerships that benefit generators, local communities and ratepayers.  To date ETI’s investments have facilitated the connection of 270 MW of wind generation in the Municipality of Chatham-Kent and have set the foundation to enable over 1000 MW of green energy in Southwestern Ontario.

With over 2000 MW of proposed generation projects in the region West of London, Ontario, ETI is developing plans for the construction of a double circuit 230 kV high voltage transmission line extending from West of St Thomas to the Municipality of Chatham-Kent.  In addition to meeting the Long Term Energy Plan’s goal of “Achieving Balance” additional benefits are derived from ETI’s proposed transmission as consolidation and sharing of infrastructure can be achieved.  Benefits that accrue to ratepayers, communities and developers include:

  • Meeting Ontario’s energy needs through a rational and cost effective expansion of Ontario’s transmission system
  • Lower environmental impacts as less transmission infrastructure is developed when generators share infrastructure
  • Energy cost savings generated when assets are optimized through regional planning
