Hydropower has been the main source of renewable electrical energy for more than a hundred years, and will continue to be so far into the future. Though hydropower is a mature technology, there is still need for and room for technological improvements, in particular for adaptation to many new challenges: New market conditions, new environmental policies, the water-food-energy-ecosystem nexus, adapting to a changing climate with its impacts on water resources and for storage of electrical energy. Hydropower offers significant potential for carbon emission reductions. With an annual generation of 4000 TWh, 16% of world electricity generation, hydropower remains the largest source of renewable energy in the electricity sector. Still, there is a potential to double the global hydropower generation, up to 8000 TWh or even more.
Hydropower planning and operation is also a very important element in water resources management, and is in the center 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. Situated at the crossroads of two major issues for development, water and energy, hydro reservoirs are vital components that can deliver services also 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, voltage 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. Here, hydropower is often a perfect companion. Renewables are also serving as an incentive for novel technological developments and operational practices.
In this Special Issue, which is a continuation of the successful 2016 Special Issue on “Hydropower”, we would like to pay special attention to the grid integration of variable renewable energy, and the role of hydropower in this process. In this context, we invite authors to submit papers dealing with the joint operation of hydro and other renewable generation, multi-market scheduling of hydropower systems, extension of the stable operating range of hydropower turbines, decrease of hydropower turbines start-up time, ageing, fatigue and maintenance of the various power plant elements due to a more flexible operation, dedicated design of hydropower turbines and generators for variable speed and hydraulic short-circuit operation, new control strategies and systems for a more flexible operation, introduction of peaking and pumped-storage hydropower plants in older hydropower systems and upgrading of existing hydropower units to variable speed.
The scope of this Special Issue is, of course, not limited to the above-mentioned topics. We will be pleased to receive papers from the full value-chain of hydropower, including resource-mapping, planning, design, construction, maintenance and operation, interaction and integration with other uses of water, and the effects of 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 submissions that pass pre-check are 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 2200 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.
