SEE hydrology and an exciting August?

Eylert Ellefsen - 7 August 2019 22:15

August can become an exciting month for traders in the SEE region. Recent precipitation forecasts have remained very dry. If these continue, there will be a further reduction in hydropower production and an additional upward pressure on spot-prices in the SEE-region. This is the conclusion gleaned from EQ’s new Pan European hydro model, which will be launched soon.

Large differences in Alpine hydro balances

Eylert Ellefsen - 3 August 2019 12:05

EQ's new hydrology models indicate that we enter August with large differences in hydrological balance across the Alpine area. Switzerland and Austria now have reservoir fillings of, respectively, 12% and 8% above their seasonal normal, whereas France and Italy are on their seasonal normal. High snow reservoirs and delayed melting during the spring, was followed by a heatwave end of June and start of July. This sparked melting, led to high inflow levels and ultimately rapidly increasing hydro reservoir levels in Switzerland and Austria.

Can it rain from the ground up?

Eylert Ellefsen - 3 July 2019 17:03

Of course not! However, during the last seven days of June 3,5 TWh worth of hydropower resources simply vanished in thin air in the CWE area. That is what our new model for energy precipitation in Germany, France, Austria, Switzerland and Italy, tells us. Another 1,4 TWh evaporated from some of the largest countries in the SEE area too. However the simulations clearly shows that the composition of the loss is mixed.

Precipitation energy SEE area

Eylert Ellefsen - 14 May 2019 12:15

As part of our ongoing hydrology project, EQ now provides energy precipitation forecasts, seasonal norms and historical data for countries in South-East Europe, covering around 50 TWh of annual hydropower production – or nearly 30% of total power supply in the region. See forecasts here.
