The hydropower industry has been a stalwart of renewable energy for over a century, with over 1,200 gigawatts of installed capacity globally. Yet, in 2020, a staggering 40% of this capacity remained idle, due to outdated technology and lack of maintenance. This is a shocking statistic, especially when one considers that hydropower is the largest source of renewable energy worldwide, accounting for 15% of global electricity generation.

The reality is that many of the world’s oldest and most iconic hydroelectric dams, built in the 1950s and 60s, are now in dire need of modernization. Aging infrastructure, inadequate maintenance, and the increasing demands of a rapidly changing energy landscape have left these behemoths struggling to keep up. The cost of upgrading these dams is estimated to be a staggering $10 billion annually, yet it’s an investment that could pay dividends for decades to come.
So, what exactly does hydropower modernization entail? In essence, it’s a comprehensive overhaul of the entire hydroelectric system, from the turbines to the transmission lines, and from the control systems to the water gates. By upgrading to modern, more efficient technologies, dams can increase their output, reduce energy losses, and even enhance their environmental performance.

One of the key drivers of this modernization push is the growing demand for renewable energy. As countries transition away from fossil fuels and towards cleaner, more sustainable sources, hydropower has emerged as a key player. However, the industry faces stiff competition from other forms of renewable energy, such as solar and wind power, which have become increasingly cost-competitive in recent years.
To stay ahead of the curve, many dam operators are turning to innovative technologies, such as advanced sensors and monitoring systems, to optimize their operations and improve their environmental impact. These smart technologies enable dam operators to predict and prevent power outages, reduce water pollution, and even create new revenue streams through innovative uses such as fish-friendly turbines.
Despite the many benefits of hydropower modernization, there are also significant challenges to overcome. One of the main hurdles is the high upfront cost of upgrading a dam, which can be prohibitively expensive for many operators. Additionally, there are often regulatory and permitting hurdles to navigate, which can slow down the modernization process.
Yet, the rewards are well worth the risks. By investing in hydropower modernization, dam operators can enjoy significant increases in energy output, reduced maintenance costs, and improved environmental performance. The industry estimates that a comprehensive modernization program can pay for itself in as little as 5-10 years, through the savings generated by improved efficiency and reduced energy losses.
As the world continues to transition towards a low-carbon future, hydropower modernization is poised to play a critical role. By reviving the past and empowering the future, this $10 billion industry has the potential to make a significant impact on our energy landscape – and the planet – for generations to come.
