This Case Study focuses on a cooperation mechanism developed in Costa Rica between La Esperanza Hydropower Project (downstream water user) and the Monteverde Conservation League, a conservation NGO that owns most of the hydropower plant's upper catchment. The objective of the mechanism is to ensure the conservation of forest cover where it already exists, since forests are perceived to provide ...

Pressure Reducing Valves (PRV) are being used for decreasing the existing extra pressure in the water distribution network. however, they dissipate a considerable amount of energy. Therefore, the idea of application of Soft Pressure Reducing Systems (SPRS) is proposed, where a PRV is replaced by a hydropower station. The heart of An SPRS is the turbo-generator. One of the advantages of this typ...

Since large part of electricity is generated by using fossil based resources, energy is an important agenda for countries. In this context, renewable energy sources are alternative to conventional sources due to the depletion of fossil resources, increasing awareness of climate change and global warming concerns. Solar, wind and hydropower energy are the main renewable energy sources. Among of ...

A hybrid hydropower power plant is a conventional Hydro-Power Plant (HPP) augmented with Battery Energy Storage System (BESS) to decrease the wear of sensitive mechanical components and improve reliability regulation performance plant. central task controlling HPP determining how total setpoint split between BESS hydraulic turbine (power splitting). This paper describes Model Predictive Control...

Water supply is a core service on which civilised society depends. It involves considerable energy consumption and, as a result, CO2 emissions (in water treatment, pumping and monitoring) and economic costs. Treated water is most commonly supplied from a central storage reservoir by gravity throughout a catchment and this water must be supplied within satisfactory pressure bands. Where the pres...

Sediment erosion not only reduces efficiency and life of hydropower turbines but also causes problems in operation and maintenance. Several factors are responsible for this erosion in hydro turbine components. This paper presents the sediment erosion types in hydraulic turbines and their components based upon an extensive literature review and the field observation at Cahua hydropower plant, Pe...

Mozambique is doing well in its implementation of renewable energies (green energies), and this a positive move as it sees to the protection environment, reduction emission greenhouse gases, country’s reliance on foreign fuels which are expensive an economic burden country with extremely high poverty index Africa. Green like hydropower, solar energy biomass already use leading, followed by hydr...
