Is Small Hydropower a Sustainable Solution for Clean Energy Generation?

Highlights:

• Introduction to small hydropower
• Latest government initiatives boosting hydropower plants
• Technological advances in the sector
• Notable acquisitions by key players in 2024

Small hydropower encompasses hydroelectric power plants with an installed capacity of less than 10 megawatts. These plants generate electrical energy by harnessing the gravitational force of falling or flowing water to drive turbines and generators. The process is part of the natural water cycle, where water is cycled through evaporation, wind, and rain, returning to its original height, thus making it a renewable energy source.

Small-scale hydropower plays an important role in electrifying isolated areas and supplementing national electrical production during peak demand periods. These systems provide a sustainable energy solution that benefits both communities and the environment by utilizing local water resources.

A look into promising government policies supporting the small hydropower industry

In the last few years, the rise in government policies and incentives has significantly fueled the growth and expansion of the small hydropower industry. These initiatives aim to lower financial obstacles, simplify regulatory procedures, and stimulate investment in renewable energy projects. Many governments provide subsidies and financial incentives to help reduce the initial capital expenses associated with small hydropower projects. These incentives take the form of direct grants, low-interest loans, and tax credits. For instance, in the United States, federal tax incentives such as the Renewable Electricity Production Tax Credit and the Investment Tax Credit significantly alleviate the financial burden on developers and investors.

Furthermore, Feed-in tariffs (FiTs) are policies that ensure a fixed price for electricity generated from renewable sources, such as small hydropower, providing a reliable revenue stream for project developers. For example, Germany has established FiTs that offer long-term contracts and favorable rates for electricity produced by small hydropower plants, thereby encouraging their development.

Moreover, Renewable Portfolio Standards require that a specific percentage of electricity be generated from renewable sources, thereby boosting the demand for renewable energy. In India, several states have established RPS targets aimed at increasing the proportion of renewable energy in their overall energy mix, which in turn promotes the development of small hydropower projects.

In addition, Governments also enact policies aimed at minimizing the environmental and social impacts of small hydropower projects. These regulations are designed to ensure that such projects are developed sustainably, with minimal ecological disruption. For instance, in Norway, laws mandate environmental impact assessments and require the implementation of protective measures for local ecosystems and communities.

Technological advances resulting in easy integration of small hydropower

Rapid technological advancements have transformed the landscape of small hydropower. Innovations in turbine design, which include advanced materials and streamlined shapes, have optimized energy extraction and lowered maintenance costs. Additionally, automation and smart monitoring systems have improved operational reliability and reduced downtime. Further, enhanced environmental impact assessments and mitigation technologies have remarkably addressed ecological concerns, thereby boosting regulatory support. Collectively, these developments indicate small hydropower as a sustainable and competitive energy solution for the future.

Moreover, integrating small hydropower systems into existing water management and irrigation infrastructure has offered a significant opportunity in this field. These systems produce clean energy with minimal environmental impact by utilizing water flows already used for agricultural purposes. This integration facilitates sustainable power generation and optimizes water resource management. Additionally, utilizing existing infrastructure lowers implementation costs and simplifies the adoption process, making it appealing to both public and private stakeholders.

Fortis Green joined hands with Rwaza Hydropower Plant to boost clean energy usage

In January 2024, Fortis Green Renewables, an investment manager providing flexible capital to small-scale renewable energy assets in Sub-Saharan Africa acquired Rwaza Hydropower Ltd. Plant, a hydropower plant in Rwanda. This acquisition has represented a significant step toward the development of the Green Fund, which offers access for investors to a stable and steady operational asset in the Rwandan market. Under this agreement, Fortis Green Renewables aims to promote the development and operation of clean and renewable energy for the African continent and the Rwaza Hydropower Plant.

ENERGO-PRO stepped into the Brazilian market with the acquisition of seven hydropower plants

In September 2024, ENERGO-PRO, a global player in the field of hydropower announced its acquisition of seven small hydropower plants in Brazil, which is managed by Brookfield Asset Management, a global investment firm. Through this acquisition, ENERGO-PRO aims to diversify its foreign portfolio by expanding its reach across Latin America. According to Petr Milev, the chief executive of ENERGO-PRO Group, through this acquisition, the company has entered a country with a large economy and long history of hydropower. He added that in the last few years, these seven plants have achieved an annual power generation above 400 GWh. In addition, this agreement has enabled the firm to strengthen its activities in the Black Sea region and Western Europe.

Wrapping up

Small hydropower has emerged as a sustainable and versatile energy solution that plays a major role in the promotion of clean energy generation, particularly in rural and remote areas. They provide reliable electricity by utilizing water flows, support local economies, and provide job opportunities to locals. Moreover, ongoing advancements in monitoring and diagnostic tools are expected to offer better management of plant performance, reducing downtime and improving overall energy output in the future.
