Lusaka, Zambia — Kalahari GeoEnergy Ltd. plans to produce power from steam resources in Zambia to help end a shortfall of electricity in Africa’s biggest copper producer, Chief Executive Officer Peter Vivian-Neal said.
“We are looking at the sedimentary basin, which in the U.S. context might have the capacity of 100 to 1,000 megawatts,” he said. The Geothermal Energy Association says the U.S. produces 3,187 megawatts of capacity from this source. Kalahari drilled its first well in Zambia’s Southern province Aug. 12 and “interpretation should be complete by end of December,” according to Vivian-Neal.
Zambia, where Vedanta Resources Plc, Glencore Xstrata Plc and Barrick Gold Corp. operate mines, has a power deficit of 180 megawatts and electricity cuts are common as state-owned supplier Zesco Ltd. struggles to keep pace with growing demand. Zesco plans to spend about $5 billion to increase generation capacity and Nava Bharat Singapore Pte Ltd. is spending $750 million on a coal-fired plant in Southern Province.
The country has capacity to produce about 2,000 megawatts of power, almost all generated by hydro plants such as Kariba North, which lies on a dam on the border with Zimbabwe.
Kalahari, based in Lusaka, the capital, might proceed with deeper drilling to prove a geothermal resource in May, depending on the outcomes of preliminary drilling that’s under way, Vivian-Neal said.
If the results are positive, the company will probably build a power plant with a megawatt capacity as much as “the high teens,” he said. One megawatt is enough to power about 500 to 1,000 U.S. homes.
“You start with something really small and show people that it works and then you add incrementally,” he said.
Kalahari’s shareholders have funded works so far, and the company will look to raise money once it has the results of the preliminary drilling, said Vivian-Neal. The company will also consider an initial public offering in the future, he said.
“We’re in a strong position to raise funding given the interest in the east African geothermal industry,” said Vivian- Neal. “A company like this conceptually might be of interest to other industry operators.”
Kenya has an estimated untapped geothermal resource of as much as 10,000 megawatts, while Geothermal Power Tanzania Ltd. plans to spend as much as $350 million to produce electricity from steam wells in that country.
