Double E Pipeline Project

Double E Pipeline Project is an operating gas pipeline in the USA. It was initially proposed as an oil pipeline but cancelled in 2011.[1] However, in 2018 the project was re-proposed, with new owners and a reduced length and capacity, to carry gas instead of oil.[2]

Original Project

The original pipeline would have originated in Cushing, Oklahoma and terminated in Houston, Texas.

  • Commodity: Oil[1]
  • Operator: Enterprise GP Holdings, ETP Legacy LP[1]
  • Proposed capacity: 450,000 barrels per day[1]
  • Length: 584 miles[1]
  • Status: Cancelled[1]

Enterprise Products Partners L.P. (a subsidiary of Enterprise GP Holdings) and Energy Transfer Partners, L.P. (a subsidiary of ETP Legacy), formed a 50-50 joint venture and launched a binding open commitment period for available capacity on the pipeline in May 2011.[3] The 584-mile pipeline with a planned capacity of 450,000 barrels per day would have provided transport from the Cushing hub to refineries in the Gulf Coast when placed in-service, which was expected at the time to be the fourth quarter of 2012.[3] The pipeline project would have included converting 230 miles of existing natural gas pipeline owned by Energy Transfer to crude oil service.[3]

In August 2011, Enterprise announced it was withdrawing from the project.[4]


In 2011, Energy Transfer Partners L.P. filed a lawsuit against Enterprise Products Partners and Enbridge Inc. after the pipeline project was canceled.[5] Energy Transfer Partners alleged that Enterprise claimed the project was not economically viable, broke the terms of the joint venture by releasing a press release without ETP's consent stating that the Double E pipeline was canceled, and then announced a deal with Enbridge to build the Wrangler Pipeline.[5]

In March 2014, Energy Transfer Partners was awarded US$319 million in damages by a Texas jury when it determined that it had been wrongfully dropped from the partnership.[4] However, the jury did not find that Enterprise and Enbridge had conspired to remove Energy Transfer Partners from the partnership.[4]

The jury's verdict was described as a "landmark decision for Texas business lawyers and their corporate clients by clarifying what constitutes a business partnership under state law."[4] Significantly, the jury found that Energy Transfer Partners and Enterprise Products Partners had formed a partnership despite the fact that specific preconditions not being satisfied that would have created binding partnership obligations, a situation likened to a common law marriage.[6]

Re-proposed Project

The re-proposed pipeline will run from Eddy County in Southeastern New Mexico to Waha, Texas.[2]

  • Commodity: Gas[2]
  • Operator: Double E LLC
  • Owner: Summit Midstream (70%), ExxonMobil (30%)[2][7]
  • Capacity: 1,350 million standard cubic feet per day (MMscfd)[2] (230,000 barrels per day equivalent)[8]
  • Length: 217.6 kilometers / 135.2 miles[2]
  • Diameter: 30, 42 inches[8]
  • Status: Operating[9]
  • Start Year: 2021[2]
  • Cost: $450 million[8]
  • Financing: US$80 million equity investment from global alternative asset firm TPG Capital;[10][7] US$175 million in loans from three undisclosed commercial banks [11][7]

In 2018 the project was re-proposed with new owners, Summit Midstream (70%) and ExxonMobil (30%). The re-proposed pipeline will carry gas instead of oil, and will run for 135 miles through New Mexico and Texas, or about a quarter of the length of the original proposal and half the capacity.[2] It will interconnect with Kinder Morgan's Gulf Coast Express Pipeline and Permian Highway Pipeline and Energy Transfer's Trans-Pecos Gas Pipeline, allowing for increased delivery to downstream demand markets of Permian supplies.[12] It transits gas from Delware Basin to Waha Hub with 117 mile 42 inch trunkline running from Lane Processing Plant in Eddy county, NM, to Waha and a 17 mile 30 inch lateral running from Loving processing plants to trunkline.[8]

The project was submitted to the Federal Energy Regulatory Commission (FERC) in 2018. In March 2020, FERC issued its environmental assessment, finding that the proposed project posed “minimal” environmental impact to the surrounding area. Local and national environmental organizations opposed this finding, citing air quality concerns. WildEarth Guardians, along with the Sierra Club and Center for Biological Diversity issued a motion to intervene in the proceedings on April 23, 2020, aiming to include their concerns in the conversation as to whether the pipeline could be built. A member of WildEarth accused FERC of failing to include an analysis on the climate impact of the combustion of natural gas from the pipeline planned to have a capacity of about 1.3 billion cubic feet per day, while emitting 35.7 million metric tons of carbon dioxide (CO2) per year.[13]

The Western Environmental Law Center (WELC), which submitted comments critical of FERC's environmental assessment on behalf of the Center for Biological Diversity, Sierra Club and WildEarth Guardians, has pointed out other deficiencies in FERC's approach. WELC representatives have pointed out that the pipeline's air quality impacts will have disproportionate impacts on minority communities living within a one mile buffer along the pipeline route. Further, FERC failed to properly consider possible water quality and endangered species concerns likely to arise as the proposed pipeline route involves crossing the Pecos River.[14]

FERC approved the project in October 2020, following which Summit Midstream said it expected to receive a FERC notice to proceed with construction within three months. The company was also aiming to secure third party financing for the majority of the project's development in the same timeframe. FERC Commissioner Richard Glick dissented on the approval due to FERC's failure to acknowledge the project's contribution to climate climate through its greenhouse gas emissions which, he said, had been quantified for the project's construction and operation. According to Commissioner Glick, due to its "refusal to assess" the potential harm of the project’s contribution to climate change, FERC had "misleadingly" stated it would not significantly harm the environment.[15]

In January 2021, FERC gave the go-ahead for general construction of the project to begin in all areas except for about two miles of the planned route. FERC advised the project promoters that work on the remaining route will need to be requested and approved separately.[12]

The project broke ground in March 2021.[16] In November 2021, Summit Midstream announced that it had placed the pipeline into service.[9]

On October 04, 2022, Double E LLC requested FERC for extension of two years to complete additional facilities on the Double E pipeline. Double E began construction of the pipeline in January 12, 2021 and on November 18, 2021 completed and began operations, except for the Lobo Processing plant and Big Eddy plant receipt point meter stations. On October 15, 2022 FERC granted extension to October 15, 2024.[17]


In December 2019, the project's majority partner Summit Midstream received equity financing of US$80 million from the global investment firm TPG as initial financing for the pipeline. Summit Midstream intends to raise the bulk of its share of the financing for the project from commercial banks.[10] In September 2020, Summit Midstream struck a finance restructuring deal with a group of creditors which holds two thirds of the company's outstanding US$155.2 million debt on a 2017 loan. The deal enabled Summit Midstream to avoid bankruptcy court.[18]

In February 2021, Summit Midstream announced that it had secured US$175 million in commitments from three leading commercial banks to finance the development of the project. The identities of the banks were not disclosed by the company.[11]

Expansion Projects

Red Hills Lateral Project

In December 2022, Double E requested FERC authorization for constructing and operating a Red Hills Lateral project. The proposed project consisted of 20 miles of 24-inch lateral pipeline connecting its existing Poker Lake Meter station to the proposed Red Hill meter station located in Eddy and Lea Counties, New Mexico. As of March 2023, the construction of the project was expected to begin in June 2023 and complete by October 2023 to begin operations in December 2023.[19]
