Kenon's Subsidiary OPC Energy Announces Plan for Construction of Power Plant in Hadera

Singapore, August 11, 2025. Kenon Holdings Ltd.'s (NYSE: KEN, TASE: KEN) subsidiary OPC Energy Ltd. ("OPC") had previously announced that it was authorized by the Israeli Government to seek authority for zoning of the land for a natural gas-fired power plant ("Hadera 2") on land owned near OPC's Hadera power plant. In April 2024, the Israeli Government rejected the plan (the "Plan") to construct a power plant on such land, following which Hadera 2 filed a petition with the Israeli High Court of Justice to overturn the Israeli Government's rejection of the Plan.

OPC today announced that it has become aware that the Israeli Government has resolved to approve the Plan, although the government decision has not yet been published.

Accordingly, OPC is preparing for the construction of Hadera 2 with an estimated capacity of approximately 850 MW (the "Project").

According to OPC's preliminary assessment, the cost of construction for the Project would be approximately NIS 4.5 billion to NIS 5 billion (approximately \$1.3 billion to \$1.5 billion).

For further information on Hadera 2 and the Plan and related proceedings, see Kenon's Reports on Form 6-K furnished with the U.S. Securities and Exchange Commission (the "SEC") on March 12, 2025 and May 21, 2025, and Kenon's Annual Report on Form 20-F for the year ended December 31, 2024 filed with the SEC on April 2, 2025.
