Costa Rica has been announced as the destination of the next World Hydropower Congress.

The World Hydropower Congress is the leading global event in sustainable hydropower development bringing together decision-makers, experts and innovators to set priorities for the sector.

The congress will be held in San José, Costa Rica, under the theme ‘Renewables working together in an interconnected world’ under the patronage of the President of Costa Rica.

The announcement was made today by Costa Rican Minister of Environment and Energy, Hon. Carlos Manuel Rodriguez, at a launch event at the UN climate conference (COP25) in Madrid, Spain.

Organised by the International Hydropower Association (IHA) and supported by Instituto Costarricense de Electricidad (ICE), the government run electricity services provider, the congress is a high-level, biennial meeting of governments, international organisations, financial institutions, research, non-governmental organisations, and industry.

Hon. Carlos Manuel Rodriguez said his government was delighted to bring the World Hydropower Congress to Costa Rica, a country which is powered by almost 100% renewable energy including around 80 per cent from hydroelectric generation.

“Costa Rica is a global leader in renewable electricity. Using hydro, wind, solar, geo and bio energy resources, Costa Rica has built a system that provides renewable electricity while ensuring social and human rights. These technologies will play a key role in the next phase of climate commitments under the UN Climate Convention. We are happy to share our experience with the region and the world, as we move away from fossil fuels and toward a net zero world by 2050,” the Minister said.

First held in Turkey in 2007, the World Hydropower Congress draws over 700 participants from more than 70 countries to agree priorities in delivering sustainable energy and water systems in the context of climate change. It represents a unique opportunity to share knowledge and insights on hydropower at the highest level.

Eddie Rich, Chief Executive of IHA, said: “With its strong commitment to hydropower and sustainable development, it’s hard to think of a better host for the 2021 World Hydropower Congress than Costa Rica. It seems fitting that they host the event that will put the focus on hydropower’s role in delivering a 100% renewable energy future in concert with other renewables.”

The last World Hydropower Congress was held in Paris, France, in May 2019, under the high patronage of President Emmanuel Macron. Delegates from 77 countries participated and the programme was organised in collaboration with some 50 partner organisations. The Report on the World Hydropower Congress is now available to download online.

Brigitte Collet, Ambassador for Climate for the Government of France, praised the commitment of Costa Rica to decarbonisation, as she formally handed over the mandate to host the World Hydropower Congress. “Costa Rica’s energy mix is truly remarkable. It is a real pleasure to hand over to your country. We believe the presidency of the World Hydropower Congress is in the best possible hands.”

Antoine Badinier from French hydropower operator EDF said his company was proud to have supported this year’s event in Paris. “The World Hydropower Congress that took place in May 2019 was a successful event for the global hydropower sector and a very special moment for EDF. On behalf of the company, I am glad to take part in this handing over ceremony to Costa Rica, and I look forward to participating in the 2021 World Hydropower Congress.”

A major new energy innovation project to demonstrate how smart hydropower technologies can deliver a low-carbon, reliable and resilient power system was launched today.

The €18 million initiative was announced by the European Commission and a consortium of 19 partners at the United Nations climate change conference (COP25) in Madrid, Spain. It will show how innovative and flexible hydropower systems can help countries across the world meet their renewable energy targets.

The XFLEX HYDRO (Hydropower Extending Power System Flexibility) project is a four-year initiative by leading utilities, equipment manufacturers, universities, research centres and consultancies. It will demonstrate how modern hydropower plants can provide the vital power grid services required by variable renewables such as wind and solar power.

The launch comes after a major UN Emissions Gap Report looking at ways to reduce global carbon emissions said that greater power system flexibility was “key” to integrating larger shares of variable renewable energy into the power supply.

The XFLEX HYDRO technologies to be tested are enhanced variable- and fixed-speed turbine systems, smart controls and a battery-turbine hybrid, each of which will be demonstrated at hydropower plant sites across Europe.

The project will conclude in 2023 by delivering a roadmap to increase adoption of the technologies across the hydropower fleet, with policy and market recommendations for governments, regulators and industry.

The initiative has received funding from the European Union’s Horizon 2020 research and innovation programme. It aims to help the EU achieve a target of achieving 32% of energy from renewable sources by 2030.

European Commission:

Mr Patrick Child, Deputy Director-General for the European Commission’s Directorate-General Research and Innovation, commented: “Combining the excellence and expertise of 19 partners from across Europe, the XFLEX HYDRO project will test innovative solutions based on renewable energy sources that will provide greater flexibility and sustainability to the energy system. The project aims to increase hydropower’s potential in terms of plant efficiency, thereby boosting electrical power systems and enabling plant and system operators to operate more successfully in electricity markets. This can make an impactful contribution to European renewable energy objectives and policies.”


Professor François Avellan of EPFL, the research institute and university leading the project, stated: “Across Europe countries are embracing large-scale electricity generation from renewables such as solar and wind power and shifting away from conventional fossil fuels for electricity generation. The growth in variable renewables is changing how power grids operate, with potential impacts on the stability and security on the whole power grid. This places unprecedented challenges on the hydropower sector to provide flexible and reliable services to the grid.

“The technologies demonstrated by the XFLEX HYDRO project will help hydropower to consolidate its critical role to support the integration of variable renewables into the power grid. This will ensure hydropower operators can maximise their performance and access future energy markets,” he added.

International Hydropower Association:

Eddie Rich, Chief Executive of the International Hydropower Association (IHA), which is responsible for XFLEX HYDRO project communications, said: “We need to decarbonise the power sector, and fast, if we are to limit the devastating impacts of climate change. Last month’s UN Emissions Gap Report is a stark reminder that we need hydropower to boost the contribution of variable renewables like wind and solar. The XFLEX HYDRO initiative represents a clear commitment by the European Commission, leading organisations from the hydropower sector and academia to invest in new and innovative hydropower technologies.”

As part of a series of interviews profiling leading Fellows of the International Hydropower Association (IHA), we meet Herbie Johnson, General Manager at Southern Company and former President of the National Hydropower Association (NHA).


Herbie Johnson is General Manager at Southern Company, where he oversees 32 hydroelectric projects with a capacity of more than 2,600 MW. In September 2019 he was elected to serve on IHA’s Board, after serving two years as President of the National Hydropower Association (NHA) in the U.S. from 2017 to 2019. He continues through, his various roles, to help shape the agenda for the industry.

Herbie says one of the highlights of his career was when, in his capacity as NHA President, he had a chance to testify before the U.S. Congress about the efficiency of the licensing process. It gave him the opportunity to share ideas on how to keep the process efficient for the next hundred years.

 “We work on legislation to keep the process of licencing and relicencing our hydroelectric plants, not only for Alabama Power Company [a subsidiary of Southern Company], but across the U.S., as efficient as possible, so it doesn’t impact ratepayers and our stakeholders in a negative manner,” says Herbie. The opportunity to work in Washington, D.C. and manage that process, as well as manage that organisation as the President, has been a dream come true for me.”

Having worked at Southern Company for more than 25 years, Herbie says it’s the “hundred-year plan” that he really enjoys about his job. “When I interact with our communities and our stakeholders, when I talk to our current employees or the young employee we’re going to hire, I want them to know our hydro plants are ‘forever assets’ and that we’ve got a plan for the next 100 years,” he says.

“Several of our dams are already over 100 years old. We want people to know that we’re already thinking about how we’re going to preserve these assets with sound engineering and innovation.”


Staff sergeant to hydrologist

Despite his success, Herbie admits he did not always envision a career in the hydropower industry. After graduating from high school, Herbie went into the military and served in the U.S. Air Force and the Alabama Air National Guard for six years. After achieving the rank of staff sergeant, Herbie sought a university education and ultimately decided on a degree in civil engineering at Auburn University.

“My father and grandfather built houses, so I always had an interest in construction,” Herbie says. “That ultimately led me to civil engineering.”

On the completion of his degree, Herbie started as a hydrologist in Alabama Power Company. “I went into the plants and learned how they operate and what it takes from a team of people to keep the plant running,” he says. “This included everything from dam safety to keeping the lights on, how to keep the water regulated, and how to make sure we meet state laws and regulations.”

Soon enough, Herbie had the chance to start managing a dam as a superintendent at Thurlow Dam in Tallassee. “From there, it just progressed. I managed other plants within our system and did some large construction projects, proving the ability to transfer my skills of civil and project management to large-scale projects,” he says. “That gave me the opportunity to come back into our hydro organisation as the General Manager and support the great team of people that keeps our hydro fleet running.”


Passing down “tribal” stories

He credits his mentors, Mike Akridge and Gene Allison, both ex-hydro general managers at Southern Company, as great influences throughout his career. Both helped him with knowledge transfer, lessons learned, and passed down “tribal” stories that were critical parts of the hydro industry and Southern Company. “The knowledge I gained from them are stepping stones for the leaders that will follow me,” Herbie says.

Knowledge-sharing is vital for Herbie and he feels honoured at the opportunity to serve on the IHA Board.

“The importance of IHA will continue to rise as the energy markets begin to value the robustness and flexibility of hydro resources,” Herbie says, adding that being a part of the Association offers many benefits.

“IHA members have access to tools, forums and subject matter experts that can open avenues for success as we integrate current and future hydro resources into the energy industry,” he says.

“The globalisation of the industry presents a unique set of challenges we didn’t face 20 years ago, and we need to work together to continue to have quality products that can be delivered in a timely manner to keep us competitive as a long-term asset in our energy markets of today and the future.”

Sarawak Energy has benefitted from a sustainability training programme which is helping the company achieve its vision to deliver reliable, renewable energy for the people of Sarawak, Malaysia.


 Pictured: IHA's Sustainability team with employees of Sarawak Energy

The state-owned energy development company and power utility is responsible for electricity generation, transmission and electricity generation, providing electricity to about three million Sarawakans in both urban and rural areas.

In the last ten years, Sarawak’s generation mix has reoriented towards renewable hydropower and away from thermal fossil fuels such as gas, coal and diesel. Its large hydropower plants include the 2,400 MW Bakun Hydroelectric Plant (HEP) and the 944 MW Murum HEP. Under development is the 1285 MW Baleh project as well as smaller hydropower projects such as the 10MW Kota 2 project.

“Hydropower generation has an important role that provides a foundation for Sarawak’s development by providing reliable, renewable and affordable energy, while meeting environmental and economic needs,” says Mohammad Irwan Aman, the company’s Senior Manager (Sustainability).

The company is committed to implementing and operating its hydropower projects in accordance with international good practice, he says, in order to “minimise any negative impacts and maximise positive impacts”.

To build understanding among its staff on how to incorporate sustainability principles into current and future project developments, Sarawak Energy recently enlisted IHA to provide advanced training on using the internationally recognised Hydropower Sustainability Tools to assess the social, environmental, technical and governance performance of its portfolio of hydropower projects.

The series of training workshops held in Kuching, Sarawak, explored how the suite of tools – including the Hydropower Sustainable Assessment Protocol (HSAP), Hydropower Sustainability ESG Gap Analysis Tool (HESG) and Hydropower Sustainability Guidelines on Good International Industry Practice (HGIIP) - can be used to enhance company practices.

Irwan says the company engaged IHA because of its ability to deliver a tailored training package. This training was divided into two categories for certified users and official accredited assessors.

“The Certified User Training was attended by our new batch of internal assessors, along with other staff who are directly or indirectly involved in hydropower development and operation, to introduce them to sustainable hydropower,” he says.

‘Training was an eye opener’

One of the trainees was Iswandy Sureia, a senior civil engineer for the Kota 2 Mini Hydro Project, who participated in the three-day Certified User Training. Despite nearly a decade’s experience with hydropower projects, he says the training was of great benefit to him.

“My primary role is to coordinate and control all phases of project execution and administration, cost, schedule and qualities of deliveries and changes of scope,” he says. “Based on my past experience, huge challenges and hurdles have been encountered from local stakeholders as there were no proper tools or guidelines to refer to. I believe with the tools in place in the business system and processes, all the problems can be minimised or eliminated.”

Iswandy adds the training was an “eye opener” for those directly involved in hydropower development as the Hydropower Sustainability Tools cover all aspects of a project’s life cycle.

“The tools can guide the team and the business entity in developing the hydropower project in a sustainable manner,” he says. “The team can also assess their performance against international good practice, areas for improvement and subsequently the recommended action to be taken.”

The course included 20 participants and eight observers from Sarawak Energy’s senior management.

‘Engaging and easy to understand’

Dayang Zanariah, a civil engineer, was one of 11 participants on the Official Accredited Assessor Training, a more comprehensive course. She learned about the various ways in which the Hydropower Sustainability Tools can be applied, ranging from decision-making to capacity building.

“The training was really engaging and further reinforced my understanding, especially in the interpretation of the statements for each of the [sustainability] topics,” she says. “The training structure was developed in a way that was easy to understand.”

Since the training course was completed in July 2019, Irwan says his team has been able to identify new ways to improve and incorporate the recently gained knowledge and lessons learned into their day-to-day responsibilities.

“In-depth understanding on sustainable hydropower and its application enables Sarawak Energy to strengthen its efforts in embedding sustainable practice into the business system by introducing and implementing new processes,” he says.
