This increase was primarily due to the new pump station on the Nipisi Pipeline which enabled throughput above contracted volumes since being brought on-stream in the second quarter of 2013.
The 2014 full-year increase was primarily due to greater interruptible volumes on the Nipisi Pipeline and the incremental revenue from the Nipisi to Trans Mountain Pipeline connection as discussed above.
Pipeline Corporation Financial Performance In 2014, Oil Sands & Heavy Oil revenue was $204 million, an increase from 2013 revenue of $195 million, largely due to higher interruptible volumes on the Nipisi Pipeline and revenue generated by the Nipisi to Trans Mountain Pipeline connection.
During the first half of the year, capital expenditures within the Oil Sands & Heavy Oil business totalled $25 million and were primarily related to the potential Cornerstone Pipeline System, discussed below, and to complete the connection of the Nipisi Pipeline to the Trans Mountain pipeline.
Year-to-date revenue in 2014 was $100 million compared to $94 million for the first half of 2013 largely due to higher volumes transported on the Nipisi Pipeline during 2014 arising from the addition of a new pump station, which was placed into service in the second quarter of 2013.
