Botswana seeks bids to build solar plants for mines

Botswana's government launched a bidding process on Tuesday to construct solar power plants near its huge Jwaneng diamond mine and for the nation's northwest, where copper assets are being developed. "This invitation ... is a request for expression of interest to construct, operate, maintain and decommission at the end of its economic life, a scalable solar power plant," the government said in a notice in the state-owned Daily News.
