First reports from HYDRO 2017: Shaping the future of hydropower

HYDRO 2017 opened in Seville, Spain, on 9 October, with welcome and keynote messages from officers of UNIDO, ICOLD, the International Energy Agency, ENDESA, SPANCOLD, the World Bank and Itaipu Binacional; some pieces of music by Manuel de Falla were played by a chamber orchestra which had been founded by the composer.

More than 1250 delegates, representing 76 nations, assembled at the FIBES Congress Centre, where a major Technical Exhibition was also held alongside the conference. (More than 100 additional registered participants who could not receive visas to enter Spain will be sent the conference materials.)

The event, hosted by Aqua~Media International Ltd (publisher of Hydropower & Dams) had the theme ‘Shaping the Future of Hydropower’. In her welcome message outlining the mission of the conference and previewing the session themes, Alison Bartle reviewed some of the achievements around the world over the past year, referring to a number of long-awaited hydro schemes which had moved ahead or where commissioning had begun.

ICOLD President Prof Anton Schleiss, in his opening message, spoke of the continuing need for water infrastructure. He highlighted the role which dams and reservoirs could play in meeting the 16 UN Sustainable Development Goals, and also demonstrated the ‘security belt’ of large dams built around the world in areas which would otherwise be prone to water scarcity. Schleiss added that dams and reservoirs would continue to be vital in many areas, especially as a result of the new challenges presented by climate change.

Luciano Canale, Senior Hydropower Specialist at the World Bank, described in his keynote address the two main types of project-based guarantee schemes offered by the Bank: loan guarantees designed to provide risk mitigation to commercial lenders with respect to key government risks which were essential for the viability of the investment; and, payment guarantees, intended to provide risk mitigation to private entities with respect to payment default on non-loan related obligations by government. Canale gave examples of guarantees which had been applied to both public and private hydropower projects.

R. P. Singh, of the Renewable and Rural Energy Unit of UNIDO, spoke of UNIDO’s mandate to promote industrial and sustainable industrial development, and the role to be played by renewable energy. He described ways in which UNIDO could support developers of small-scale hydropower, in terms of technology transfer, capacity building, social mobilization and the management of demonstration schemes. He also drew attention to the ‘World Small Hydro Development Report’ which had recently been compiled and launched by UNIDO, based on reports from 160 countries.

Niels Nielsen, Secretary of IEA Hydro, gave details of IEA’s Cooperation Programme on Hydropower. He highlighted current and future activities in the fields of: small hydro; economic evaluation of energy and water management services provided by multipurpose hydro schemes; greenhouse gas emissions from hydro reservoirs; fish protection; modelling cascade developments; and decision-making for hydro plant renewals.

Francisco Arteaga, CEO of the Andalucía and Estremadura division of the Spanish utility ENDESA, described his company’s structure, mission and activities, stressing in particular its commitment to environmental protection and sustainability.

Dr José Polimón, President of the Spanish Committee of ICOLD, outlined trends in Spanish dam construction, and he also stressed the importance of capacity building and training, drawing attention to some examples of work in this field by his Committee.

Two side events had taken place on the day before the main conference began: Itaipu Binacional had organized a symposium on the operation of large hydro plants, where operational issues at plants such as Three Gorges and Itaipu had been discussed. Dr Rui J. Correa da Silva presented some of the outcomes during the plenary opening of HYDRO 2017.

The other co-located event was a workshop on small hydro, organized by Prof David Williams and Gordon Black, of Learning Hydro, UK. Around 45 participants worked in groups during the day under the guidance of the tutors, and by the end of the workshop had been able to design their own small hydro plant, based on data from a real project.

Over the three days of HYDRO 2017, a broad range of topics relating to hydropower planning, development, operation and maintenance were covered, in a total of 35 sessions, running in four parallel tracks. Much emphasis was placed this year on addressing challenges, from financial risk to natural hazards (for example relating to climate and unfavourable site conditions) and man-made hazards (such as requirements for cyber security, and working on hydro projects in conflict zones).

Safety was an underlying theme in sessions dealing with dams, powerplants, gateworks and spillways; one talk focused on the safety of construction workers on site.

Research and innovation in hydro machinery, the increasingly important role of pumped storage, and the importance of adequate maintenance and timely refurbishment were other key themes of the technical sessions.

In the environment session, speakers covered a broad range of topics, including wildlife management in Uganda, maintaining environmental flows and water quality monitoring. Chairman Markus Aufleger commented that environmental issues should not be regarded as a tiresome duty but rather as a key element in the implementation of a sustainable and successful hydro project.

In a session dedicated to fish protection, speakers covered a variety of cases, from large tropical rivers to cold water streams in the Alps. The audience was made aware of a wide field of research in this field, as well as some innovative solutions such as flexible electric fish fences. There were two talks about the Xayaburi scheme in Laos, the first run-of-river scheme on the Mekong for which a unique system of up- and downstream fish passage facilities has been developed.

On social aspects, presentations covered livelihood restoration programmes, long-term planning for social mitigation, and lessons learned from the Murum resettlement scheme in Sarawak, Malaysia.

As part of the session he led a panel discussion on the theme ‘When, how, what and where to maximize the full potential of hydro balancing in decarbonizing electricity markets’.

Dr George Annandale, Consultant, USA, who co-chaired a session on sedimentation management with Sultan Alam of France. He also gave a talk in the session on climate issues, on the subject of water supply in the context of climate change.

Dr Peter Mason, MWH Stantec, UK, who chaired the session on spillways and plunge pools. In his summary he commented that the continued safe operation of spillways could not be taken for granted, and he stressed the importance of regular monitoring and inspections.

Prof Luis Berga, Hon. President of ICOLD, Spain, who chaired the session on upgrading civil structures, and also presented some concluding remarks in the closing plenary session.

F. Lempérière, of Hydro Coop, France, who gave a talk in the dam safety session highlighting the increasing risk to construction workers, especially in the less developed countries. As construction processes had become more mechanized over the years, risks on site had increased, he felt. He drew attention to ICOLD Bulletin No. 80, published some 25 years ago, which had set out valuable guidelines and stressed that these were still valid today.

M.G. de Membrillero Ortuña of Ofiteco, Spain, putting forward some practical suggestions on dam safety training, during the session on capacity building.

Some of the speakers in the session on research for hydro machinery. From left: chairman Prof François Avellan, Director of the Laboratory of Hydraulic Machines at EPFL, Switzerland, Philipp Conrad of Voith Hydro, Germany; Prof Hermod Brekke, NTNU, Norway; Kai Shimokawa, Voith Fuji, Japan; and Marcelo Magnoli, Voith Hydro, Germany.

Session chairman John Gummer, shown left, and six of the speakers for the first half of the session of ‘Hydraulic machinery: Design and operation’. This session was as usual one of the busiest, with a total of 14 talks by speakers from the leading manufacturing companies, research laboratories and universities.

Bruno Trouille of Mott MacDonald, USA (shown right), who chaired the track of four sessions on pumped storage. Beside him is José Freitas, Head of Maintenance and Administration at EDP, Portugal, who co-chaired the first of the four sessions. Seven case studies were presented, from which valuable lessons could be drawn.

Daniel Paschini of EDF, France, making some opening comments during the session he chaired on operation and maintenance. The leading talk in his session gave details of new World Bank initiatives on operation and maintenance; there were also presentations on a new monitoring platform adopted by ENDESA, Spain, as well as several new ideas for inspections and surveillance systems.

Paulo Erbisti of Brazil, who chaired a session on gates and valves. Topics included improving the safety of existing power-operated gates, the commissioning of headgates in France, new intake gates for the Torán reservoir in Spain, enhancing the operating system at the spillway gates of Victoria dam in Sri Lanka, and an innovative design for inlet valves at an Austrian pumped-storage scheme.

R. Taherzadeh of Tractebel Engie, France, chairing the session on tunnels. He commented that the talks could be divided into two categories: technologies applied in tunnelling for hydro schemes; and, challenges faced in underground works, at the design phase, as well as during construction. There were contributions to the session from Germany, Italy, Switzerland, Bolivia, Bhutan and South Africa.

H. Irfan Aker of Dolsar Engineering, Turkey, introducing the session which he chaired, on project planning and implementation. Speakers covered a wide range of case studies, including projects in Chile, Myanmar, Malaysia, Angola, Cameroon and Ethiopia.

Dr Harald Kreuzer of Switzerland, chairing the session on dam safety. He felt the session had highlighted an interesting dichotomy in considering safety issues between large and small dams. On the one hand there had been advances in the use of risk assessment for large, well documented dams, he said, while on the other hand there was a tendency to neglect the safety of thousands of small dams, where the risks were considered to be less significant. He welcomed the fact that the safety of small dams was to be the subject of a question at the next ICOLD Congress.

Dr Andy Hughes, UK, who co-chaired (with Dr José Polimón of Spain) a panel discussion on ‘Planning for the next generation of hydro experts’. The first part of the session focused on talks by four trainee engineers, in their last year at University, who were participating in a summer programme organized by Multiconsult, Norway. This was giving them ‘hands-on’ experience, working as a multi-disciplinary team for a real client. This was followed by an open forum, which led to the conclusion that succession planning and knowledge transfer was not all about training, but was a complex issue involving many issues and stakeholders.

Vincent Denis, Director of Mhylab, Switzerland, who co-chaired one of two sessions on small hydro, with Prof B. Pelikan. Their session presented some case studies from around the world, and covered projects in Africa, Asia and Europe.

Luciano Canale of the World Bank presenting the outcomes of his session, and offering some general comments about the conference, which he described as the “leading event for the hydropower profession”.

John Gummer summarizing the presentations on hydraulic machinery, during the closing plenary session. He commended the speakers for covering a broad range of topics within a limited time, ranging from fish-friendly turbines to revolutionary designs for tidal powerplants. Such diversity, he felt, allowed for the presentation of many topics which some participants might not ever encounter elsewhere, and which would give them good insight into problems faced by others in the industry.
