Tanzania has significant geothermal potential and is working to develop 200MW of geothermal power by 2025. The Tanzania Geothermal Development Company is spearheading development efforts and currently has 5 priority projects at various stages. Ngozi and Songwe have completed surface studies and are ready for test drilling. Developing local capacity and securing funding from the government, Green Climate Fund, and other partners are keys to realizing Tanzania's geothermal ambitions.

16. 8. Local Capacity building for geothermal development
a) Human skill development
• Good cooperation with local and international academic institutions
(UNU-GTP, AGCE/UNEP, Japan, local institutions, etc.,)
• Developing organizational & institutional capacity (geosciences,
engineering, compliance, project management, drilling, direct uses,
etc.)
b) Essential equipment and tools
• Acquisition of basic exploration equipment e.g.., MT, TEM, etc.
• Processes for procurement of small drilling rig is on going

17. 1. Target is develop 200 MW from geothermal by 2025.
2. Projects consider both power generation and direct uses
3. Formulation of geothermal law on going
4. Development of local capacity for geothermal projects
5. Ngozi and Songwe projects are ready for test drilling
6. Mobilization of funds (GoT, GRMF, SREP, and other partners) to
support geothermal development ongoing
