In conjunction with the combined companys other oil transportation assets, this pipeline will provide
Energy Transfers customers with best-in-class access to the Houston Ship Channel, the Gulf Coast refinery complex and St. James markets.
In addition, Energy Transfers vast network of pipelines, which handles over 4 million barrels per day, will allow customers the flexibility to
access its previously announced VLCC project planned from its Nederland terminal. Were advancing discussions on this project and as this project gets closer to FID, we will provide more specifics.
Before going into a more detailed discussion around third quarter earnings, growth CapEx and liquidity update, I want to provide an update regarding the
latest developments on other growth projects.
Lets start with the Bakken Pipeline capacity optimization. As we have mentioned, the Bakken Pipeline
received sufficient market interest during the December 2018 open season for us to move forward with plans to further optimize the system capacity. More recently, in July, we announced a binding supplemental open season to solicit additional shipper
commitments for transportation services. As a result of increased interest, as well as the SemGroup acquisition announcement and the Ted Collins Pipeline project, we have extended and modified the current supplemental open season to include HFOTCO
as a destination for shippers.
The initial phase of the Bakken Pipeline optimization above its current capacity of 570,000 barrels per day will be based
on commitments made by shippers that we have already received, as well as commitments made during the current open season. This capacity to serve the commitments received is expected to be in service in early 2021.
In the meantime, and upon completion of the permitting phase, we expect to provide up to approximately 30,000 barrels per day of incremental capacity by mid-2020 utilizing our current system configuration. And as Bakken volumes and customer demand continue to grow in the future we will be in position to efficiently increase the system capacity up to 1.1 million
barrels per day over time.
Now looking at PE1, 2 and 3 Pipelines, which are part of our Permian Express joint venture with ExxonMobil, we continue to
operate at capacity during the third quarter. And the PE4 expansion, which added an additional 120,000 barrels per day of capacity to our Permian Express Pipeline system from Colorado City to Nederland, Texas, went into full service on October 1st and is operating at full capacity as well.
Now looking at our Mariner East system, as a reminder, we
placed the initial capacity of ME2 into service December 29, 2018, and volumes continue to ramp up in the third quarter of this year. In October, we completed modifications to ME1 and Marcus Hook to enhance the reliability of the system and
allow for improved flows through the facility. Consistent with the second quarter, volumes during the third quarter remained strong across the Mariner system, reaching as much as 300,000 barrels per day of NGLs through the Marcus Hook Industrial
Complex.
Additional inbound transportation modes, including trucking and rail, remain heavily utilized during the third quarter as well. We recently
completed two local connections for delivery of propane and ethane to new facilities, including to a new power plant in Cambria County in western Pennsylvania and to the Sinking Spring area. We expect more connections like this to be made in the
future. We have also executed an additional agreement for butane transportation with a local NGL distribution facility in Pennsylvania. International LPG arbitrage economics remain strong in the third quarter demonstrating the strength of this
terminal in efficiently reaching the best markets for our customers. Our further expansion efforts at Marcus Hook are underway and progressing nicely with increased facility capacity expected for fall of 2020.
Due to the permit bar, ME2X is now expected to be completed in mid-2020. Even with the delayed in service date, we
will still be able to meet our contractual commitments. The next tranche of volume ramp-ups on the Mariner East system are expected to occur in the spring coinciding with the startup of the Northeast NGL
season which drives increased customer demand. However, because of modifications we recently completed, we do expect to ramp up additional ethane volumes this winter.
Looking at the Lone Star assets, as a reminder, the 150,000 barrels per day Frac VI went into service in mid-February
and has been full since March. On Fracs VII and VIII, both of which will be 150,000 barrels per day, we continue to expect them to be in service in the first quarter of 2020 and the second quarter of 2021, respectively. We anticipate both fracs will
ramp up to full capacity very quickly. Upon completion of Fracs VII and VIII, our total frac capacity at Mont Belvieu will be over 1 million barrels per day.
And on our 24-inch, 352-mile Lone Star Express expansion, well add over
400,000 barrels per day of NGL pipeline capacity from the Permian Basin to the Lone Star Express 30-inch pipeline south of Fort Worth, Texas. We continue to expect to be in service by or before our original
estimate of the fourth quarter of 2020. In addition, we continue to further develop our storage capabilities at Mont Belvieu.
