Karel Kraml, company director, chief of conceptual solutions, and hydraulics

Karel is an independent expert in hydropower with more than 15 years of experience.

As chief designer or project manager he has responsible for the completion of over 30 hydroelectric power plants in operation worldwide. As the managing director of Stream sro he focuses on hydropower development, realization & funding in Asia, South America and the European Union.

After graduating from CTU in Prague in 2003 where he studied Branch hydropower, his career started as a member of a team reconstructing 7 hydropower plants in Macedonia, under a contract with the Macedonian government. From 2006 - 2008 he worked as the project manager of a hydropower development in Vietnam and since 2009 has been team leader on a number of hydropower design and construction projects in southern America, Africa and across Europe. Notably, he served as chief designer on the LAC hydropower plant in Liberia, serving a rubber tree plantation on an island with a population of fifteen thousand. In 2016 he became the managing director of Stream s.r.o., a company that acts worldwide, focusing on hydropower design, management, construction, and funding. One example of a completed project is the new 15 MW Corani 5 hydropower project in Bolivia, where Stream was responsible for both designing the plant and overseeing its construction.   

Břetislav Heczko

Chief architect and civil engineer

Bretislav graduated from the faculty of architecture at Czech Technical University in Prague in 2007. He has worked as an architect and visualisation specialist on many industrial and public construction projects, and since 2011 he has participated in hydropower projects in Africa, Italy, and, of course, on Stream sro projects.

Some of his more interesting projects include producing construction animations for the LAC project in Liberia, and design of the Svijany hydropower plant in the Czech Republic, which was nominated for a number of architecture awards.

Jiří Příhoda

Chief structural engineer

Stanislav Mitrega

Project manager and drone photogrammetry expert

Stanislav graduated from the University of Technology in Brno in 2023 with a degree in Water Construction and Hydropower Engineering. He was awarded the Signum Prosperitatis award for excellent academic achievements and significant contributions to the university. Since 2016, he has been gaining experience as a designer of utility networks. In 2018, he started working as a designer of water structures at STREAM HYDROPOWER, where he gradually advanced to the position of project manager.

He is proficient in the use of the most advanced software from Autodesk Company and other advanced technologies for land surveys, potentially suitable for power plant projects. Such technologies include photogrammetry using drones.

Since 2020, he has led surveys in countries including the Czech Republic, Georgia, Malaysia, Indonesia, and Liberia, identifying sites beneficial for small hydropower projects. Stanislav has led or participated in the design of dozens of hydropower projects, managing them from inception to obtaining building permits and supervising subsequent construction.

Jakub Monsport

Water structures designer and hydraulics expert

Jacob has a strong commitment to environmental sustainability and ecological responsibility. He graduated from Brno University of Technology, specialising in Water Structures and Water Management, driven by his interest in mathematics, physics and nature. His final thesis focused on the hydraulics of the shaft spillway, where he studied flow stages (on both physical and numerical models) and proposed modifications to improve its capacity without reaching overpressure flow.

During his studies, he joined STREAM HYDROPOWER in 2020 as a part-time employee, working on pond designs, including one tested by a Q₁₀₀ flood, and later began to contribute to hydropower plant projects. After graduation, Jacob took on a full-time role, applying his analytical approach, knowledge of hydraulics, and experience with calculations.

Since then, he has designed and structurally assessed piles of anchor blocks, designed penstocks and intakes on projects in Georgia and Malaysia, and conducted various studies in these countries. Meanwhile, in his homeland, he worked on a small hydropower plant Upice.

He aims to bring efficiency to design processes by automation and advanced skills in tools such as MS Excel, QGIS and CIVIL3D.

Filip Mokrejš

Water structures designer

Water and its crucial role in nature and everyday life have always interested Filip, leading him to decide to study water resources management in high school. This interest was further pursued at Brno University of Technology, from which he graduated in 2023.

Filip gained his first practical experience with hydropower projects during his studies while working for STREAM HYDROPOWER, where he had the opportunity to contribute to projects in Georgia.

Later, he participated in surveys in Malaysia and Indonesia, focusing on identifying suitable locations for hydropower plants. His responsibilities included in-situ data collection as well as preparing feasibility studies for these projects. A significant professional milestone was his involvement in the Simolap hydropower plant project in Indonesia, where he was part of the engineering team and contributed to the detailed design of this project.

Filip is proficient in advanced software tools, such as CIVIL3D and QGIS, which facilitate effective analysis of terrain data and the design of solutions tailored to the specific needs of each location.
