Waterway are one of the most efficient means for transportation. It can be applied for energy storage demonstrating the potential of using these structures with renewable energy systems, here, through an analysis of energy alternatives. This paper analyzes two different solutions for energy supply, using the Locks of the Tucuruí powerplant, in Brazil. A photovoltaic power station is compared to a hybrid system composed by photovoltaic and pumped storage. The alternatives are discussed technically and economically. The energy costs of the scenarios are calculated based on the evolution of the expenses and the related payback time are found. The water resource is exploited responsibly, keeping balanced the pumped and turbined volumes of water. The grid works as an intermediate storage and allows the operations with a single pump-turbine conversion. Its location lowers down the initial investment in favor of the hybrid system as the more viable alternative. It was found that the locks could be used to handle up to 263 kW and 387 kW of electricity in turbine and pump mode, respectively. This paper gathers crucial data on the use of hydropower in waterways locks that support the integration of renewable energies surrounding the locks. In addition, the use of pumped storage plants to store energy from intermittent sources, present themselves as an innovative opportunity to, using the own head available at facility, improve the financial return of meeting the energy demand through an economically and environmentally responsible energy system, may be useful in similar facilities around the world.

水路是最有效的交通方式之一。通过对替代能源的分析，它可用于储能，证明在可再生能源系统中使用这些结构的潜力。本文使用巴西的Tucuruí发电厂的Locks分析了两种不同的能源供应解决方案。将光伏电站与由光伏和抽水蓄能组成的混合系统进行比较。在技​​术和经济上讨论了替代方案。方案的能源成本是根据费用的演变来计算的，并找到相关的投资回收期。负责任地开发水资源，使抽水和透平的水量保持平衡。网格用作中间存储，并允许通过单个泵-涡轮转换进行操作。它的位置降低了最初的投资，转而使用混合动力系统作为更可行的选择。结果发现，在涡轮机模式和泵模式下，这些锁分别可用于处理263 kW和387 kW的电力。本文收集了有关在水闸中使用水力发电的关键数据，这些数据支持闸中周围可再生能源的整合。此外，使用抽水蓄能电站来存储间歇性能源，这本身就是一次创新的机会，可以利用设施中可用的自有水头，通过对经济和环境负责任的能源系统来提高满足能源需求的财务回报，在世界各地的类似设施中可能有用。
