The best possible knowledge of available water in the power system is needed to calculate the price trend in the electricity market on the short and longer term. For price forecasts and overall production planning at the regional and regional levels, it is desirable to have ongoing information on magazine volume in both representative individual magazines and total water content aggregated across regions or regions. For long-term planning, some multi-year magazines are dominant, while knowledge of the situation in magazines with short useful lives is important for price assessments and marginal situations. For traders and market analysts, it is important to have up-to-date and rapid information on the volume changes in magazines that are most relevant to their price analyzes and market assessments.
The problem today is that information about the water content of single reservoirs is not released continuously, but only as aggregated information covering a region. Most power companies treat single reservoir data as critical information that is not published. Therefore, simulations of power price developments are often based on estimates and inaccurate data for individual magazines or more general information about the water situation. In a highly competitive power market, it is also crucial to the quality of planning that the information used is up-to-date and as accessible as possible.
The space-borne analytics company EDI has developed a service for continuously updating the water situation in lakes and power plant reservoirs based on satellite data. The service is based on continuous analysis of satellite measurements combined with AI-based modeling of water level variations. Based on level measurements, the service consists of various products such as magazine water level, magazine volume, filling degree and energy potential for specified magazines. EDI receives satellite data continuously and the products can be updated weekly. Products can be tailored to the individual user depending on which areas and magazines are important to the user, as well as what refresh rate is desired. The information can be updated and disseminated on different platforms depending on the user’s needs and routines – from e-mail to web-based visualization.
