Oman's Al Batinah Power Co and Al Suwadi Power Co, which launched twin initial public share offers on Sunday and are owned by the same consortium, will double their profits from 2014 to 2018 as they pay off start-up costs, a top executive said. The firms, whose owners aim to raise a combined 62.7 million rials ($163 million) through the sale of 35 percent of each company, together provide just over a quarter of the electricity for Oman's main power grid - around the capital, Muscat. The companies were required to go public and list on the sultanate's bourse under the terms of their licences, having launched operations in April 2013.
