A strong activity & production outlook

Our activity and production outlook remains positive. We work closely with the government to achieve its ambition of becoming a regional power hub and delivering universal access to power by 2030.

We anticipate gas fired electricity to rise substantially in line with regional power demand. The current capacity of Mnazi Bay exceeds 100MMscf/d, which comfortably meets the current average daily demand. We reached 103 MMscf/day (gross) for five consecutive days during December 2020 and a record high of 103.36 MMscf/day was achieved on 15 December 2020.

As Tanzania develops its industrial economy, we are ideally positioned to provide additional supply to meet expected demand. We will also continue to work with the Tanzanian Government to supplement its hydropower capabilities and ensure we are fulfilling our own sustainability ambitions.

The Tanzanian Government’s target to increase the generation capacity within the country to 5,000MW by 2025 provides the framework for gas exploration and production companies to start planning and developing their investment strategies. With 3,000MW of this power to be generated from gas and 2,000MW from hydroelectricity — our long-term growth outlook is positive.

With our sustainability ambitions at the forefront, we work with stakeholders to find innovative ways to power Tanzania’s industrial and domestic electricity demand.
