Mkonline has introduced hydrological models for pricezones Norway+Sweden

The hydrological models at Mkonline have so far been based on Statnett-regions in Norway and four geographical regions in Sweden. The goal for Mkonline has for a while been to establish all our hydrological models on price-zone levels as we do for all other fundamental data. Continue reading Mkonline has introduced hydrological models for pricezones Norway+Sweden

Alpine snow and groundwater levels still below normal

During January we posted two blogs commenting the low hydrological situation in the Alps as precipitation in December came out at the driest level for several decades across CWE and the Alpine region. The precipitation deficit regarding energy meant nearly 13 TWh, so the snow package was extremely low by New Year. The situation did not improve during January which was icy and dry, and deficit in snow and groundwater was even more severe by the end of January.

All-time low Swiss hydro reservoirs

Critical levels can be reached this winter

In our blog of January 16th, we focused on the very low hydrological balance across the CWE region. The hydrological deficit is still about
20 TWh lower than normal which may result in nearly 5000 MW reduced hydropower (- 25%) during May-July.

In this blog post, we will focus on the hydropower situation in Switzerland. Continue reading All-time low Swiss hydro reservoirs

Spiking SEE spot prices and extremely low hydropower levels

Spot prices are currently increasing heavily in the SEE area as the hydropower situation is getting extremely scarce these days. The weather outlooks are dry too, so this situation will at least persist towards the first part of February. We already published a blog story of the situation and focused on hydrology/hydropower and market prices (Spot/FWD). Continue reading Spiking SEE spot prices and extremely low hydropower levels

Outlooks for CWE hydropower production 2017 strongly reduced due to low snowlevels

In our blog of Dec 16th, we focused on the extremely low snow levels in the Alps. In some locations, it has been observed close to all-time low snow levels the past 80-100 years. There was a similar situation in December 2015, but during January and February, the situation improved a lot due to torrential rains- and snowfall across the Alpine region. Current outlooks for 2017 are different, there has so been no improvement in the snow situation and present cold outlook results in strongly reduced hydro-reservoirs as well.

Extremely low snow levels in the Alps

 4th lowest level in 80 years observed

The snow levels are low in most parts of the Alpine region these days according to snow curves at MKonline. In Switzerland, there has been made an observation at a 2400m altitude that confirms the 4th lowest in the past 80 years!

The snow levels across the CWE-region are currently 12 – 13 TWh lower than normal, see snow curves from MKonline below. The snow levels were very low last year too, but the situation improved strongly during Q1-16. The question is, will this happen again?

Updated hydropower models for Bulgaria

We are pleased to inform that we have updated our hydropower models for Bulgaria (BG). The implementation includes a new Run-of-River and Total production model and a revised Inflow model. The improvements are obtained from applying actual data from ENTSO-E and new river flow data for the inflow calculations.

Actual hydropower data for CEE now available

We are pleased to inform that actual hydropower data for all countries in the CEE region have been added to MKonline. This marks the first step towards our goal of introducing hydrological models for the region. We expect this work to be started next year.

All countries in the CEE area (Poland, Czech Republic, Hungary, Slovakia) include Run-of-River, Reservoir and Total production. Pumping production is represented for all countries, except Hungary. Pumping consumption is only available for Czech Republic. The data are based on ENTSO-E numbers.

Data from Czech Republic have been available for some time at MKonline, however these data have been adjusted. The new implementation revealed that our previous estimate for Run-of-River production was erroneous and in fact was closer to the current total production.

Please contact us if have any questions to the updated numbers on support@mkonline.com.

Updated hydropower models for RO and SI

We are pleased to inform you that our Run-of-River (RoR) and Total hydro production models for Romania and Slovenia have been upgraded and revised. The most significant improvement is the use of actual data from ENTSO-E for the daily RoR production.

The previous model concept used riverflow data scaled to monthly UCTE numbers to estimate the daily RoR (see the chart from the short term hydrology pages on MKonline below).

Slovenia-OldROR

The new concept apply ENTSO-E data scaled to monthly UCTE numbers, which in example for Slovenia this means about10% higher values than indicated by raw ENTSO-E numbers. The forecast methods have only had minor revisions (see the chart from the short term hydrology pages on MKonline below). The other countries in the SEE area are left unchanged.
