Shumba Energy secured the first equity commitments to develop an $80 million solar project in Botswana as part of the coal company’s plan to shift to renewable energy. The company’s green energy unit, Shumba Renewables, received commitments of $950,000 from international investors, Shumba Energy’s MD Mashale Phumaphi said in an interview Tuesday, without disclosing the names. Full funding for the 100-megawatt solar project that will be the nation’s largest and situated in north-eastern Botswana is expected by the second quarter of next year, Phumaphi said.
