Exhibit 99.1

Kenon’s Subsidiary OPC Energy Ltd. Announces that CPV, a subsidiary of OPC, is in

Negotiations to Increase Holdings in Two Power Plants in its Energy Transition Business

Singapore, July 14, 2024. Kenon Holdings Ltd.’s (NYSE: KEN, TASE: KEN) subsidiary OPC Energy Ltd. (“OPC”) has announced that CPV Group LP (“CPV”), a 70%-owned subsidiary of OPC, is in negotiations with two parties to acquire their ownership interests in two natural gas-fired power plants in the PJM market in which CPV already has an interest (the “Projects”), thereby increasing CPV’s ownership interests in the Projects.

If both acquisitions are completed, OPC expects the total investment to be in the range of approximately $210 million to $240 million, depending on the final terms of the agreements, which are under discussion between CPV and the sellers of the Projects. OPC further expects that, to the extent each acquisition is completed, CPV’s interest in each of the Projects will increase significantly, but CPV would not acquire full ownership of the Projects. If agreements are reached with the sellers, OPC expects completion to occur in the second half of 2024.
