Tanzania Opens International Tender for Kiejo-Mbaka Geothermal Consultancy — What It Means for East Africa’s Drilling Frontier By Alphaxioms | Geothermal Intelligence & Deal Facilitation | May 2026 Tanzania is quietly accelerating its geothermal agenda. The Tanzania Geothermal Development Company Limited (TGDC) has issued an international tender inviting qualified firms to provide consultancy services for the Kiejo-Mbaka Geothermal Project in Rungwe District, Mbeya Region. The tender closes on 5 June 2026 and represents one of the most strategically important geothermal procurement milestones in East Africa this year. This is not routine procurement. It is a critical step in transitioning Kiejo-Mbaka from exploration confirmation into structured, bankable development. What the Tender Covers The scope of the assignment is technically intensive and strategically important. TGDC is seeking a consultancy firm to deliver: Planning, design, supervision, and management of a d...
Exploring Geothermal Energy: Hawaii's Renewable Energy Frontier
By : Robert Buluma
In a bold move towards achieving its goal of 100% renewable energy by 2045, Hawaii is venturing into the realm of geothermal energy. With abundant sunshine and wind being intermittent resources, the state is now turning its attention to tapping into geothermal sources to bolster its energy portfolio.
The Hawaii State’s Energy Office, led by Chief Energy Officer Mark Glick, is spearheading this initiative. Glick emphasizes the importance of understanding the potential of geothermal energy, stating, "For me, it’s a real priority for this office to better understand how far we can go with geothermal."
To kickstart this endeavor, $5 million from COVID federal relief funds have been allocated for conducting slim hole drilling to explore geothermal reservoirs. The focus of this exploration will initially be on Maui, with promising signs indicating the presence of viable geothermal sources along the rift zone of the island.
Currently, the Puna Geothermal Venture stands as the sole commercial geothermal power plant in Hawaii. Despite facing challenges, including a temporary shutdown following the 2018 volcanic eruption, the plant has recently received approval to increase its energy output to 46 megawatts, a significant boost from its current capacity.
Mike Kaleikini, the Hawaii Affairs Director at Puna Geothermal Venture, explains that this increase in production will be facilitated by the replacement of older power-generating units with modern, more efficient ones. This upgrade aims to not only enhance energy output but also mitigate potential environmental impacts and improve community relations.
Acknowledging past concerns about environmental impact and safety, Kaleikini underscores the importance of proactive outreach and communication with the community. He assures that steps have been taken to address past issues and regain public trust.
Looking ahead, the focus remains on expanding Hawaii's geothermal energy capacity. The identification of potential drilling sites on Maui signifies a step forward in this journey. While specific locations have not yet been disclosed, the narrowing down of options indicates progress towards harnessing the untapped potential of geothermal energy in the state.

As Hawaii continues its transition towards a sustainable energy future, the exploration of geothermal resources represents a crucial milestone. By diversifying its renewable energy sources, the state not only moves closer to its ambitious renewable energy goals but also sets an example for others to follow in the global fight against climate change.
