The 29th United Nations Climate Change Conference (COP29), held in Baku from November 11–22, 2024, has underscored the critical role of Azerbaijan and Kazakhstan in advancing Caspian Sea regional energy transitions. Both countries leveraged their positions along the Middle Corridor to present ambitious renewable and nuclear energy strategies. Azerbaijan: Renewables and the Middle Corridor Azerbaijan, the host and chair of COP29, has positioned itself as a renewable energy connector between Central Asia and Europe. Its energy strategy reflects a pragmatic approach to transitioning from hydrocarbons, which accounted for 88% of government revenues in 2023, to a diversified portfolio incorporating solar, wind, and hydropower. Azerbaijan has prioritized key renewable energy projects to align with its goal of achieving a 30% renewable share in its electricity mix by 2030. Among these is the operational Garadagh Solar Power Plant, a 230-megawatt (MW) facility developed by the UAE's Masdar, which generates 500 million kilowatt-hours (kWh) annually. Complementing this is the planned Alat Solar Project, a 400-MW solar installation expected to be operational by 2027. These projects aim to bolster domestic electricity supply and expand Azerbaijan’s capacity to export renewable energy. The Caspian Offshore Wind Initiative, backed by the European Bank for Reconstruction and Development (EBRD), seeks to harness the Caspian Sea’s favorable wind conditions. A 1-gigawatt (GW) wind farm is under preliminary study, with construction anticipated to begin by 2026. This project could transform Azerbaijan into a renewable energy hub for the Middle Corridor, particularly as Europe reduces its dependency on Russian energy. Kazakhstan: Nuclear Ambitions and Renewable Diversification Kazakhstan’s energy strategy focuses on nuclear power and renewables, driven by the need to reduce coal dependency, which still accounts for two thirds of its electricity generation. The government’s approval of its first nuclear power plant, following a nationwide referendum in October 2024, is central to this strategy. The planned nuclear reactor, located near Lake Balkhash, will generate 1.2-GW of electricity, replacing approximately 20% of coal-fired generation. This initiative complements Kazakhstan’s status as the world’s largest uranium producer, supplying over 40% of global demand and generating $3.6 billion in export revenues in 2023. Potential consortium members for the project include South Korea’s KEPCO, France’s Orano and EDF, China’s CNNC, and Russia's Rosatom, although economic-sanctions issues complicate Russia’s involvement in the nuclear sector. Kazakhstan is simultaneously scaling up renewable energy projects, with several key initiatives underway. The Zhanatas Wind Farm, operational since 2022, produces 100-MW of power, and the Shelek Solar Park, a 200-MW solar facility near Almaty, is expected to come online in late 2025. Together, these projects aim to increase renewables to 15% of Kazakhstan’s electricity mix by 2030, quintupling the level from 2023. The Trans-Caspian Electricity Cable Project At the COP29 conference, Azerbaijan and Kazakhstan, along with Uzbekistan, announced an ambitious trans-Caspian electricity cable project through an underwater transmission system. This infrastructure initiative, estimated to cost $2.5 billion, seeks to establish an electricity corridor linking Central Asia with European markets, representing a significant step in regional energy integration.
