TGDC to acquire modern geothermal drilling plant

​​​​​​​TANZANIA Geothermal Development Company (TGDC) is set to acquire new drilling rig by June next year for geothermal exploration projects.

TGDC General Manager, Kato Kabaka.

Briefing the journalist in Dar es Salaam on the TGDC accomplishment report during the 60 years of Tanzania independence, TGDC General Manager, Kato Kabaka said that the company is in the process of procuring a geothermal drilling plant that will be able to drill wells up to 2000 meters deep.

“We’ve already signed the agreement for the purchase of the plant, which is to arrive in the country in June, 2022 and it will be used in drilling all planned projects,” said Kabaka.

According to him, the new drilling rig will mark a milestone in development of country’s geothermal resources.

“We will keep   exploring several geothermal sites for potential development, and mean while  continue to implement different  geothermal projects that we have at hand  as all necessary producers have been done starting with getting  an expert who will be responsible in overseeing drilling programs, all technical specification, as well as buying of  drilling materials,

starting with an approximately $144/-m  Ngozi  project  located in the Ngozi area in the Mbeya  region which will be focusing on  electricity generation by 70 megawatt(MW),” said Kabaka.

The implementation of this project including research and evaluation started in September 2015 and is expected to be completed by 2023, he said.

He further note that apart from that there is Songwe project located at Songwe Region is expected to start with 5 MW of electricity generation and other  geothermal direct use projects and the cost of this project is approximately $32 million  and its  implementation started in 2018 with finishing expectation to be 2023.

There is also Kiejo-Mbaka project also from Mbeya region is expected to start with 10MW of electricity generation and other geothermal direct use projects and the cost of this project is approximately $75 million and its implementation started in 2017 with finishing and expected to finish in 2024.

The project is currently in the process of verifying geothermal resources by using verification wells that will be drilled in the project area and will be done into two stages

The first step is the drilling of three shallow boreholes at 300/75 degrees Celsius each, with the aim of exposing the scientific information conducted by  STAMICO internal  contractor and second is drilling four excavation four boreholes 1500-1900 meters deep exploratory wells and then followed up by production wells and construction of power plan.

He further noted that there is also a Luhoi Coastal project is expected to start with 5MW of electricity generation and other geothermal direct use projects and also Natron Arusha project in Arusha region with 60Mw and other geothermal direct use project  and its  implementation started in 2019 and expected to finish in 2025.

''Geothermal is one of the most important and strategic resources in promoting and bringing about economic and social development in the country  and as well focus in  ensuring that this resource is developed faster so that it can contribute to economic growth and national development, create new jobs, eradicate poverty and improve the lives of citizens," he noted.
