南非启动最大抽水蓄能项目伙伴资格预审：1.5吉瓦 Tubatse 电站遴选战略合作伙伴
约翰内斯堡——据南非国家电力公司 Eskom 官网 10 月 13 日发布的新闻稿，Eskom 旗下可再生能源业务 Eskom Green 已发布资格预审文件（编号 RFQ No. E3611GXR），公开遴选战略合作伙伴，参与 Tubatse 抽水蓄能项目的开发、融资与交付。这是该项目采购流程的第一阶段，通过资格预审的投标方将进入后续的建议书征集（RFP）阶段。
Tubatse 项目位于林波波省 Roossenekal 附近的 Elias Motsoaledi 地方市辖区，依托 De Hoop 大坝作为水源。项目规划装机 1.5 吉瓦，配置 4 台单机 375 兆瓦的可逆式水泵水轮机组，储能容量约 21 吉瓦时，满负荷发电可持续约 14 小时。项目建成后，将超过现役 Ingula 抽水蓄能电站的 1,332 兆瓦，成为南非最大的抽水蓄能电站。
Eskom 表示，项目拟采用公私合作（PPP）模式，装入独立的特殊目的公司（SPV）推进；目前项目用地已经落实，环境许可已经获批。Tubatse 被列入南非公正能源转型计划，并获 Infrastructure South Africa 列为战略综合项目（SIP 20d）。
这一项目酝酿已久：2007 年，项目更名为 Tubatse，装机规模提升至 1.5 吉瓦；2009 年项目一度搁置；2024 年 11 月，法国开发署签署 650 万欧元赠款，支持项目前期开发工作。抽水蓄能利用上下水库之间的落差，在电力富余时抽水储能、在用电高峰时放水发电，是支撑风电与光伏并网、提供长时电网调节的重要储能形式。（据 Eskom 官网新闻稿与南非《Business Day》10 月 14 日报道）
South Africa Opens Partner Prequalification for 1.5GW Tubatse Pumped Storage Scheme, Its Largest Ever
JOHANNESBURG — Eskom Green, the renewables arm of South Africa's state utility Eskom, has issued a request for qualifications (RFQ No. E3611GXR) to select a strategic partner for the development, financing and delivery of the Tubatse pumped storage scheme, according to an Eskom statement dated October 13. The prequalification is the first stage of the procurement process, and qualifying bidders will advance to a request-for-proposals (RFP) stage.
The project is located near Roossenekal in Limpopo province, within the Elias Motsoaledi Local Municipality, and relies on the De Hoop Dam as its water source. It is planned at 1.5 gigawatts, with four reversible pump-turbine units of 375 megawatts each and energy storage of about 21 gigawatt-hours — enough for roughly 14 hours of generation at full output. Once completed, it would overtake the operating Ingula pumped storage station (1,332 megawatts) as South Africa's largest pumped storage plant.
Eskom said the project is to be structured as a public-private partnership housed in a separate special-purpose vehicle; the land has been secured and environmental authorisation is in place. Tubatse forms part of South Africa's Just Energy Transition programme and has been designated a Strategic Integrated Project (SIP 20d) by Infrastructure South Africa.
The scheme has been decades in the making. It was renamed Tubatse in 2007, with capacity raised to 1.5 GW; it was shelved in 2009; and in November 2024 the French Development Agency signed a €6.5 million grant to support early-stage development. Pumped storage uses the elevation difference between upper and lower reservoirs — pumping water uphill when electricity is plentiful and releasing it through turbines at peak demand — and is a key long-duration storage technology for integrating wind and solar power into the grid.
