Programme highlights

Once again, we will have a full and varied programme for our annual conference in April, covering a range of practical topics, and including some new session topics. While some papers are still being reviewed, we present below highlights from the planned sessions. Regular programme updates will be posted in the coming weeks on our website. Registration is now live!

    • In the light of the success of our recent SOLAR-HYDRO 2021 virtual conference held in July, which brought together solar PV experts with hydro and dam engineers, to discuss practical aspects of floating solar PV on hydro/dam reservoirs, we are introducing this topic to HYDRO 2022 with a track of sessions. The number of questions, and amount of discussion at the recent event clearly indicated that more time is needed on this important and rapidly emerging technology, which has a major future role to play in so many parts of the world.

     

    • Another session will deal with hybridization of renewable energy systems, and the role of pumped-storage working in synergy with intermittent renewables. One paper will deal with a hydro-solar simulation tool for pumped-storage powerplants. Another will discuss an economic model for revenues of hybridized pumped-storage plants. One author will look at how the licensing of offshore wind in the North Sea is bringing new initiatives for pumped-storage schemes.

     

    • Continuing on pumped-storage, there will be a talk on model studies to look at pressure pulsations and compensation measures in the case of a 1500 m head single-stage storage pump; a case study featuring the first direct MMC converter for variable speed pumped hydro storage; and, a description of the first underground pumped-hydro scheme (500 MW) moving ahead in Estonia.

     

    • As usual, hydropower technology will form an important part of the programme, with at least two sessions on hydraulic machinery. Subjects will range from the pitfalls of specifying turbine parameters for bidding, to technical issues such as: waterhammer analysis in Francis units; field measurements compared with model tests and CFD for large Kaplan machines; methods for diagnosing cavitation; robotics for the underwater inspection of turbine runners, to reduce costs, risks and outage time; and, air admission systems to enhance flexible operation of Francis units.

     

    • One of our new sessions this year will focus on innovative remote systems for gaining reliable data, for planning, designing and monitoring. This will coincide with the commercial launch of the HyPOS (Hydro Power Suite) EU Horizon 2020-funded research project, aimed at water resources and sedimentation management. Topics will include: Earth observations; the use of Drones/UAVs; geospatial tools; remote sensing; and remote supervision

     

    • Small hydro is once again a popular topic this year, and two sessions will be devoted to technical advances, innovation and case studies. Examples will include: exploring the efficiency of low and ultra-low head small hydro plants; optimizing cross-flow turbine operation; a double regulated mixed flow turbine for SHP applications; a new micro hydro turbine for in-pipe installations; design concept and operational feedback on a small hydro plant on the Rhône; and, lessons learnt from small Pelton projects, regarding cavitation and bearing damage.

     

    • One of the two sessions on finance will be entitled: ‘The Good, the Bad and the Ugly? – three key financing approaches for hydropower’.  After some introductory talks, the session will consist of a panel discussion considering the three main trends in financing for large hydropower, and assessing the relative merits of each for low-income countries looking to develop their infrastructure.  The session will begin with a summary of three projects in Uganda, each with a different financing structure, and panellists will compare and contrast this with experience from elsewhere in the world.

     

    • Among the many topics to be presented on sedimentation will be: an innovative sediment pre-assessment study to facilitate sediment removal activities; optimising the use of dredged sediment for use in the building industry; recent advances in hydraulic modelling, and in sedimentation modelling; Web-based sediment analysis using satellite, modelling and in situ data; and, enhancing the design of desanding facilities

     

    • Hydro plant safety, upgrading and refurbishment will be another important subject to be tackled, with upgrade studies presented from Malawi, Khazakhstan, Croatia and Austria; and a talk on asset management during the pandemic. One speaker will address hydro efficiency upgrades for the ‘EU Green Deal’, and another will outline operational problems and their solutions, at Indian hydro plants.

     

    • Our track of sessions on civil engineering will focus on developments in design and construction, dam monitoring and safety, remedial work, materials for civil works, challenging sites, as well as drilling and tunnelling work. Innovative hi-tech monitoring systems will be described, and there will be safety-related case studies or research reports from India, Myanmar, Israel, China, Germany, France and Switzerland.

     

    • On spillways and gates there will be talks on the hydraulics of a large stepped spillway, case studies of spillway upgrades, modelling to optimise operation of spillways, and the new intake gates for the Chivor extension project in Colombia.

     

    • Our session on the hazards facing hydro projects either at sites with challenging physical conditions, or in areas prone to extreme climatic events will again highlight key aspects threatening the safety of water infrastructure. An expert on geohazards will discuss lessons learned from the Chamoli disaster in India, and there will also be presentations on the risks posed by GLOFs, geotechnical challenges, earthquakes and floods. In the light of catastrophic flooding which occurred this year in parts of Asia and Western Europe, a special session will be devoted to flood management.

     

    • Innovative systems for fish protection, including new developments in both passes and deterrents, as well as turbine designs to ease fish passage will be the subject of a number of papers within the session on Environment. New developments from Austria, Finland and Brazil will be presented, as well as on-going research in Greece, the USA and China. One speaker will present research on rapid construction technology for a long fishway at a high dam in a steep canyon, another will discuss biodiversity in boreal reservoirs, based on 20 years of experience in Québec, Canada.

     

    • Cross-border projects will be the theme of another set of presentations, following the great success of the session on this topic last year. There will be discussion on transboundary schemes in Africa, Asia and Europe, highlighting the regional benefits of these projects, and drawing on some case studies.

     

    • A special session will discuss opportunities for the European industry to support chances for small hydro development in Africa and Latin America. The findings of the EU-supported research project HYPOSO (Hydropower Solutions) will be presented with particular emphasis on the HYPOSO Platform and the promotion opportunities it provides for the European small hydropower industry and stakeholders from five target countries: Uganda, Cameroon, Colombia, Ecuador and Bolivia. The project advancement includes progress towards identification of potential small hydro sites in the target countries and the development of the HYPOSO Map, as well as the results of the analysis of the small hydro framework conditions there. Selected case studies for each country will be presented, and challenges in their development will be discussed. Experts will also elaborate on the idea of knowledge and capacity development in the hydropower sector for the developing and emerging countries. The session will help bring together European hydropower industry representatives with stakeholders from the target countries, resulting in opportunities for collaboration between them and increasing the chances for small hydro projects in Africa and Latin America.

     

    • IEA hydro logoAs usual, two sessions are being organized by the International Energy Agency, one on the studies being carried out globally on both the future of hydropower and research initiatives to support this growth, with the other a general session on the work of the Hydropower TCP.  Topics in the first session will cover IEA’s Renewable Energy Market Report with a special focus on hydropower; the US DoE Research Program on Hydropower; the Norwegian HydroCen Research Program on Hydropower; and, IEA Hydropower Technical Collaboration Programme (TCP). In the session on the work of the TCP, there will be reports from some of the Annexes, including Annex XVI, Hidden and Untapped Hydro Opportunities; and, Annex IX/XII; Valuing Hydropower Services and Hydropower and the Environment. The latter will include presentations on ‘Hydropower enabling integration of variable renewables’ and ‘The benefits and value of flood control and drought management from hydropower. There will also be a talk on Annex XIII; Hydropower and Fish.
