We consider longand medium-term production planning and hedging in a hydropower system under price and inflow uncertainty. The price uncertainty is modeled with a multidimensional forward curve model that considers time dependant spot volatility, the volatility curve’s maturity effect, and the forward curve’s correlation structure. We give a simple and intuitive parameterization for the optimal...

Using a system dynamics approach, an integrated water resources system model is developed for scenario analysis of the Saskatchewan portion of the transboundary Saskatchewan River Basin in western Canada. The water resources component is constructed by emulating an existing Water Resources Management Model. Enhancements include an irrigation sub-model to estimate dynamic irrigation demand, incl...

The world’s tenth largest river in terms of annual flow volume, the Mekong is comparatively undeveloped in terms of its exploitable water resources, so that its hydrological regime remains largely natural and unregulated. However, this is about to change given the scale of water resources schemes proposed over the next two decades. These include over 23 cubic kilometres of reservoir storage beh...

E nvironmentalists often go to great lengths to block the construction of new dams because dams interfere with fish migration, inundate terrestrial habitats, and interrupt natural flows that are necessary for critical ecosystem processes. However, few environmental issues are so simplistically black and white, and dams are no exception. Dams can be an important source of clean energy and for po...

The world is undergoing a transition to more sustainable energy sector dominated by renewable sources. This paper proposes an innovative solution that consists of catching water from streams at high altitudes fill storage containers and transport them down mountain, converting the potential into electricity with regenerative braking systems electric trucks storing it in truck's battery. stored ...

Today, technological innovation is often called upon to deliver solutions to the sustainable development challenges that the world faces. The integration of different technological systems is promoted as a main option for that goal. By integrating systems, waste from one system can be used as feedstock for another system, equipment can be usedmore efficiently by economies of scale, and/or the s...
