Eight international lenders signed a Letter of Support on the sidelines of Cop31 in Antalya this week for two 1GW solar projects that Acwa is to develop in Turkey. The Sivas and Taşeli projects will have combined investment of around €1.6bn and are expected to begin operating in 2029. They are the first phase of a 5GW renewable energy program previously signed between Saudi Arabia and Turkey in February.
