In a stunning revelation, a recent report by the International Hydropower Association (IHA) estimates that the global hydropower industry is sitting on a $1.3 trillion untapped opportunity in modernization, which could be the key to meeting the world’s growing energy demands while reducing carbon emissions. This staggering figure is a wake-up call for governments, investors, and utilities to accelerate efforts in modernizing existing hydropower plants and harnessing new technologies to unlock the full potential of this renewable energy source.

Hydropower, which accounts for about 60% of the world’s renewable energy capacity, has been a cornerstone of the global energy mix for decades. However, many existing hydropower plants are aging, with some dating back to the 1950s and 60s. These legacy plants are often inefficient, with low generation capacity factors and high maintenance costs. Moreover, they are not equipped to handle the increasing variability of renewable energy sources, such as solar and wind power, which are changing the way the grid operates.
The modernization of hydropower plants is no longer just about upgrading equipment and increasing efficiency; it’s about integrating them into a modern, smart grid that can respond to changing energy demands and incorporate a range of energy sources. This requires a holistic approach that involves upgrading turbines, generators, and control systems, as well as implementing advanced monitoring and control technologies.
One of the key drivers of modernization is the growing demand for flexibility and resilience in the grid. As renewable energy sources become a larger share of the energy mix, they bring variability and unpredictability to the grid. Hydropower plants, with their ability to store energy and respond quickly to changes in demand, are uniquely positioned to provide this flexibility. Modernized hydropower plants can be designed to operate in a range of modes, from peaking power to long-duration energy storage, making them an essential component of a modern grid.
The benefits of hydropower modernization are numerous. In addition to reducing greenhouse gas emissions and improving air quality, modernized hydropower plants can create jobs, stimulate local economies, and provide a reliable source of energy that is less susceptible to price volatility. Moreover, modernization can help to reduce the environmental impacts of hydropower, such as fish passage and water quality concerns, by incorporating more efficient and sustainable technologies.
Despite the vast opportunities presented by hydropower modernization, there are significant challenges to overcome. One of the main hurdles is the high upfront cost of modernization, which can be a significant barrier for many utilities and governments. Additionally, there are concerns about the availability of skilled workers and the need for significant investment in infrastructure and training.
However, the benefits of hydropower modernization far outweigh the costs. As the world continues to transition towards a low-carbon economy, hydropower will play an increasingly important role in meeting energy demands and reducing greenhouse gas emissions. The $1.3 trillion opportunity in modernization is a wake-up call for governments, investors, and utilities to work together to unlock the full potential of hydropower and create a more sustainable, resilient, and efficient energy future.
