Guangxi Gas Pipeline Network 广西天然气管网 is a pipeline network in Guangxi Autonomous Region, China, with segments that are proposed, in construction, and operating.

Network background

On December 30, 2012, Guangzhou-Nanning gas pipeline, a branch of West-East pipeline 2, began operating. [1]This is the first time a gas pipeline entering Guangxi and beginning to supply gas. Another source of gas is Sino-Myanmar Gas Pipeline, delivering gas from Kyaukryu, Myanmar. It entered Guangxi at Hechi and ended at Guigang. Sino-Myanmar gas pipeline began operating in 2013[2]. There are two LNG terminals in Guangxi. But only Guangxi LNG Terminal in Beihai transports gasified LNG through pipelines. It began operating in 2016. Based on these three gas sources, Guangxi established its gas pipeline network. The gas in Guangxi is mainly for household use.

By 2020, Guangxi has completed 2638 kilometers of gas pipeline, reaching 12 municipalities. It aims to add another 2600 kilometers of gas pipeline by 2025. [3]

In February 2021, Guangxi issued the Urban Gas Development Plan of Guangxi Zhuang Autonomous Region (2021–2030), 广西壮族自治区城镇燃气发展规划 (2021–2030年).[4][5]

As of June 2019, the plan noted that operating gas pipelines in the region reached 2282 kilometers with 9 pipelines. There were also dedicated shorter pipelines to reach various cities and counties totalling 402 kilometers (both operating and under construction).[4]

The development plan predicted that province-level gas consumption in 2025 would be 4x that of 2019. In order to meet and encourage such demand, the province intends to speed up gas development infrastructure, including LNG terminals and factories, gas storage, and gas pipelines.[4]

To promote this development and the province's aims to reach every county (县县通), the plan sketches new proposals in three stages:

  1. By 2022, the plan intends to build 16 county-level branch pipelines
  2. By 2025, the plan intends to build an additional 17 county-level branch pipelines
  3. By 2030, the province intends to build an additional 18 county-level pipelines (depending ultimately on the population's needs, and the natural gas market)

Location

The pipeline runs from Beihai, to Hechi, Guangxi, China.[6]

Project details

Guangxi LNG Terminal Transport Pipeline 广西LNG外输管线[7]

The source of the pipeline is the Beihai LNG Terminal. The pipeline contains one major pipeline and 6 branch lines.[8] The total length is 1332 kilometers. [9]

Due to the dynamic change of the market demand, the major pipeline segment Liuzhou-Hechi and four branches were cancelled. The trunk pipeline was shortened to 497 kilometers and the total length shrank to 731 kilometers.[9]

In July 2020, the ownership of the pipeline was transferred to PipeChina along with the Beihai LNG Terminal.[10]

  • Parent company: Sinopec[11]
  • Capacity: 4 bcm/year
  • Length: 684 km / 425.02 mi
  • Status: Operating
  • Start year: 2013, 2015[6], 2019

The pipeline is composed of multiple branches listed below.

Beihai-Maoming Branch 粤西支线 (北海-茂名)

Beihai–Maoming Branch, also known as Guangdong West Branch (粤西支线), was partially completed in 2019 with the Beihai–Zhanjiang segment.[12] The operating date of Zhanjiang-Maoming segment is unknown. By September 2020, the pipeline has passed the completion inspection.[13] The line was fully put into operation on August 8, 2020. The pipeline is an important natural gas energy channel that connects Guangdong and Guangxi and promotes the construction of the Guangdong-Hong Kong-Macao Greater Bay Area and the Hengqin Guangdong-Macao Deep Cooperation Zone.[14]
