TransCanada, looking to begin construction on the additional 1600 km crude oil extension of the Energy East Pipeline, has signed a provisional multimillion - dollar order with ABB Canada for the development of 22 electrical houses (e-houses) along the pipeline route which would supply electricity to the pipeline's pumping stations.

The $15.7-billion Energy East pipeline would carry a million barrels a day of western crude as far east as Saint John to serve domestic refineries and international customers.

Opposition to Energy East is mounting among nearby mayors on environmental grounds. The National Energy Board – and ultimately federal cabinet – has the authority to approve Energy East. But as witnessed in British Columbia, strong opposition from provincial and local governments can erect significant hurdles for crude pipeline projects.

If the government gives its ok, TransCanada has said it could begin construction by 2018. The pipeline would be ready for use by 2020.
