Ghana’s producing offshore gas fields are located on its Western border with Côte d'Ivoire, while its capital Accra and its industrial suburb Tema are located in the East. As a result, investments had to be made both in processing gas domestically, but also in making it available across the coastline to the power enclaves of Takoradi (West) and Tema (East).
To process domestic gas, state-owned GhanaGas commissioned the 150 MMscf/d Atuabo Gas Processing Plant in 2015, connecting to a national gas grid running to Takoradi and Prestea. The plant processes gas from Tullow Oil’s Jubilee and TEN fields. In 2017, Eni commissioned Sanzule’s 405 MMscf/d Onshore Receiving Facilities (ORF) to process its own gas from Sankofa Gye-Nyame before injecting it into GhanaGas’ network. Availability of domestic supply enabled the Takoradi power enclave to decarbonize and grow as a stable electricity supply base.
To make gas available in the West, Ghana established in 2019 a reverse flow on the existing West African Gas Pipeline. The project ensures that imported gas can flow from Nigeria to Tema and Takoradi but also enables domestic gas to flow back from Takoradi to Tema.
In anticipation future gas supply gaps, Ghana is now planning an additional onshore gas pipeline from Tema to Takoradi, thereby reinforcing flow capacity between its western and eastern industrial and power hubs.
