Effects of Short-Term Regulation by Power Plants on Erosion and Water Quality of a River

  • Erkki Alasaarela
  • Markku Virtanen


The demand for electricity varies with time of year, week and day. Electricity cannot be stored in Finland, so the output must be adjusted to meet the demand. Short-term regulation of regional hydropower plants is important. They generally account for 30–50% of the value of the annual production of power plants (Lehtonen 1985).
