中企改造非洲首座地热电站全部机组并网：奥尔卡里亚一期装机45兆瓦升至63兆瓦
新华社 11 月 11 日自肯尼亚内罗毕报道，非洲第一座地热电站、位于肯尼亚纳库鲁郡「地狱之门」国家公园的奥尔卡里亚一期地热电站，经中国企业升级改造后，三台机组已全部并网发电。在地下蒸汽总量保持不变的情况下，电站总装机容量从 45 兆瓦提升至 63 兆瓦。
这座电站于 20 世纪 80 年代投运，已有 40 多年历史。升级改造项目由中国电建集团山东电建三公司承建，2023 年 8 月开工，在老厂房与既有设施约束下完成三台机组的更新，并引入冷凝器、循环水泵、冷却塔等中国制造设备替换老化机器。肯尼亚发电公司电气专业经理 Maurice Awuor 表示，改造后电站的装机约占肯尼亚全国总装机容量的 2%，这是肯尼亚近三年来唯一一个投运并新增装机的地热改造项目。
肯尼亚地处东非大裂谷，地热资源丰富。据肯尼亚能源和石油监管局数据，地热发电量常年占该国总发电量的 40% 左右，是第一大电力来源。按肯尼亚国家能源契约 2025 至 2030 年的目标，该国计划到 2030 年把地热装机提升至 1,681 兆瓦，并实现电力 100% 清洁化。
Chinese-Built Upgrade of Africa's First Geothermal Plant Fully Connected: Olkaria I Capacity Rises From 45 MW to 63 MW
Xinhua reported from Nairobi on November 11 that all three generating units of Olkaria I, Africa's first geothermal power station, have been connected to the grid following an upgrade built by a Chinese company. Located in Hell's Gate National Park in Nakuru County, Kenya, the plant's total installed capacity has risen from 45 megawatts to 63 megawatts using the same total supply of underground steam.
Commissioned in the 1980s, the plant is more than four decades old. The rehabilitation, carried out by SEPCOIII Electric Power Construction Co., a subsidiary of Power Construction Corporation of China, began in August 2023 and renewed all three units within the constraints of the old plant, introducing Chinese-made equipment including condensers, circulating water pumps and cooling towers to replace ageing machinery. Maurice Awuor, an electrical engineering manager at the Kenya Electricity Generating Company (KenGen), said the upgraded plant accounts for about 2 percent of Kenya's total installed generation capacity and is the only geothermal rehabilitation project in the country in the past three years to be commissioned and add capacity.
Kenya sits on the East African Rift and is rich in geothermal resources. According to the country's Energy and Petroleum Regulatory Authority, geothermal power consistently supplies about 40 percent of Kenya's electricity, its largest single source. Under the Kenya National Energy Compact 2025-2030, the country aims to raise geothermal capacity to 1,681 megawatts by 2030 and reach 100 percent clean electricity generation.
