Challenges

There's serious competition for the use of water. Water-resource and power-system operators need to consider and improve how they manage this valuable resource, always bearing in mind and balancing the constraints imposed by power generation; flood control; management of drought risks, recreation, maintaining water quality, irrigation, domestic and industrial users, the fishing industry, and more.

In addition, waterpower-systems operators and hydroelectric utilities need to identify the best scenarios for maximizing revenues in the electricity market, using long-term contracts and spot-energy market transactions. Ancillary service requirements must be considered, too. Finding the best ways to manage operations is particularly challenging for utilities that must coordinate multiple generation sources in addition to hydro, such as wind, solar, and thermal generation.

Given the growing evidence for global climate change and the declining snow pack in recent decades, better inflow forecasting tools are required. A significant amount of hydrological data has been compiled. It can be overwhelming unless it's managed well, with the best, most up-to-date tools and analytics.

Solutions

Vista DSS™ suite

This leading software is regarded by many as the world’s premiere commercial system. It's a toolbox used by system operators, dispatchers, and engineering-operations staff to help determine long-term storage planning and management, short-term (hourly time resolution) scheduling, and real-time dispatch. Vista DSS™ is what you need to help achieve the maximum value for your water resource and generation systems

Why your power plant needs the right LTSA

Herbert Lam

Long-term service agreements can be lifelines for owners of gas turbine and combined-cycle power plants. But be sure you know what these complex contracts can and cannot do.
