Hydropower has been the main source of renewable electrical energy for more than a hundred years, and will continue to be equally, or even more, important in the future, certainly for another 100 years. Though the hydropower of today is a mature technology, there is still room for technological improvements and a need for adaptation to many new challenges: New market conditions, new environmental policies, the water-food-energy-ecosystem nexus, and how to adapt to a changing climate with its impacts on water resources. Hydropower offers significant potential for carbon emission reductions. With 16% of worldwide electricity generation, hydropower today remains the largest source of renewable energy in the electricity sector, and, still, there is a potential to increase global hydropower generation by 200%–300%.
Hydropower planning and operation are closely linked to water resources management, and is in the centre of the “Water-Energy-Food-Ecosystem Nexus”. During hydropower development, one nearly always needs to consider many other users and uses of water, making both planning and operation much more challenging than for other renewables. The sustainability issue is becoming increasingly important, and today it is hardly possible to develop hydropower resources without a thorough discussion and documentation of its long-term sustainability. Situated at the crossroads of two major issues for development, water and energy, hydro reservoirs can often deliver services beyond electricity supply, such as flood control, transport, recreation, and water supply for irrigation, municipal consumption, and industry.
In addition to providing energy and capacity, hydropower offers several other advantages to the grid, such as supporting frequency control, “black start” capability, energy storage, and the capability to balance demand and generation at timescales from seconds to weeks. The rapid development of other renewables, like wind and solar, is creating an increasing demand for energy storage and load balancing, and, here, hydropower is often a perfect companion. We invite papers dealing with the integration of renewables in the grid, and, in particular, the role of hydropower in this process. We would also like to see papers discussing how the existing and ageing hydropower system could be refurbished and extended, for example, by new pumped-storage plants, in order to maximize energy, capacity, and other ancillary services.
To summarize, in this Special Issue on hydropower, we invite authors to submit papers from the full value-chain of hydropower, including resource-mapping, planning, construction, maintenance, and operation. We would like to see papers on novel technology development, use of new materials, new or improved methods for planning including sustainability analysis, the role of hydropower storage and capacity in a grid with increasing share of highly variable generation from wind and solar plants, and on how to develop and operate hydropower plants optimally under the uncertainty brought by climate change.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Energies is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
