UK-based engineering consultant Penspen is on track to complete a feasibility study update for the Trans-Saharan Gas Pipeline (TSGP) before the end of September, according to industry sources.

The contract was awarded to Penspen in March of this year, with a completion period of six months, and is proceeding on schedule, sources say.

The pipeline project is estimated to be worth $13bn-$25bn.

In March, Penspen said that the pipeline was “a landmark infrastructure project with the potential to transform African energy dynamics, enhance economic integration and bolster global energy security”.

The pipeline, which spans more than 4,000 kilometres from Nigeria to Algeria, is jointly sponsored by Nigerian National Petroleum Company, Algeria’s Sonatrach and Niger’s Sonidep.

The planned project will facilitate the transportation of up to 30 billion cubic metres of natural gas across West and North Africa annually, ultimately linking to European markets.

Penspen said: “This ambitious initiative is poised to unlock new economic opportunities for transit countries, foster regional cooperation and support Africa’s growing energy demand.”

The TSGP project was initiated in 2002 by the collaborative efforts of Nigeria and Algeria, with Niger admitted as a co-sponsor in 2008.

Penspen delivered the original feasibility study for the project in 2006, finding the pipeline to be technically and economically feasible and reliable.

Penspen was engaged to revalidate and update its feasibility study, considering earlier route options.

The project is being delivered from Penspen’s offices in the UK and Middle East, with support from fellow Sidara brand Dar, which is established and active in the three countries.

The study covers an analysis of the regional gas market. It also includes environmental and social evaluations, economic and financial analysis, cost estimation, legislation and consultation reviews, risk analysis, and the development of the scope of work for the front-end engineering and design work.
