In 2000-05, 61 per cent of hydro-electricity was generated in Norway and 33 per cent in Sweden.5 Swedenisthelargest Public statistics show that average hydro reservoir levels measured in per cent of reservoir capacity have been reduced after 1990. We have used the power-market model EMPS11EMPS is the acronym This captures the fact that information about the snow reservoirs reduces the decision maker’s level of uncertainty about future inflow levels. Computational analysis of the Nordic power market undertaken using the model confirms the importance of modeling multiple inflow sources, with the addition of the snow reservoirs reducing the span between the highest and lowest expected future spot Strong inflows to Nordic hydro reservoirs in Week 35 saw stocks edge up 0.9 percentage point to 98.85 TWh despite strong Norwegian and Swedish power exports, Nord Pool data showed Wednesday. The cold weather in the Nordic area postpones the snow melting, and this could eventually mean, that some of the Nordic hydro reservoirs run dry late in the spring. Published 26. mars 2018 The very cold weather conditions, which have influenced large parts of 2018, have made their marks on the hydrological situation in the Nordic area.

Nordic hydro reservoir levels

The Swedish snow reservoir is at a 20-year all-time high too, and … In 2017, the Norwegian reservoirs had a water level of 28.2 % at the time it was lowest, while the Swedish reservoirs did not get lower than 18.9 %. The fact that the hydrological situation is under pressure also points towards high spot prices during spring. Nordic Hydro is currently at a yearly low, with 2019 and 2020 production trading at 63.5 and 87 Eurocent/MWh at the time of writing. Similar prices were last observed during Q1 last year. Following the high trading activity in March, the number of Nordic Hydro trades conducted by … This makes the system less flexible than a pumped hydro system, which can be turned on and off at any time. • Generation from Norway’s hydro plants is further constrained by maximum and minimum acceptable reservoir water levels, minimum acceptable watercourse flow rates and variable permitted release volumes at different times of the year.

Coastal reservoirs are fresh water storage reservoirs located on the sea coast near the river mouth to store the flood water of a river.

The Swedish snow reservoir is at a 20-year all-time high too, and we expect about 30% higher inflow than normal during the weeks 21 – 33.

For Norway, Scandinavia's dominant hydro reservoir player, calculated inflow of 2.2 TWh for week 28 was 45% below normal, national energy directorate NVE said. "The increase in week 29 is expected to be 2.0 TWh, which is 47% below normal," it said.
