Karpowership, the world’s biggest supplier of floating gas-fired power plants, said it’s committed to delivering what would be its biggest ever project as South African activists mounted a fresh legal challenge against the company’s plans. The Organisation Undoing Tax Abuse said on Thursday it sued the National Energy Regulator of South Africa for granting generation permits to the Turkish company in September saying the country’s best interests weren’t taken into account regarding the cost of contracts and the impact on the climate.
