In recent weeks, in Spain it has rained so much that the swamps of the peninsular center are so full that they will have to unwind. A news that will directly influence the electricity bill, but for good.
With which we never count. When we talk about generation and renewable capacity, the two sources that come to mind are usually solar and wind. However, there are more renewables that provide energy to the electrical system such as hydroelectric plants. This year, in addition, the rains have arrived as a gift because wind energy has failed in its contribution, which has made the hydroelectric take more prominence.
How will it affect our light bill? In this situation of incessant rainfall throughout the Spanish territory, which also will lengthen throughout the month of Marchhydroelectric plants have already generated more than 9,000 GWh, which represents a 18.4% of energy mix. In addition, the generation and storage capacity of hydroelectric plants He has reached The 5,599 MW, which represents 20.65% of the total system structure. This contribution is very important to see in the coming months a decrease in light prices.
The rain, an ally. This phenomenon will help lengthen the low price period, which is important for homes and companies that fear the increase in rates. Compared to the previous years, and taking into account that this year wind energy He has been failing In their contribution, the rains have become great allies.
It can warm up. If we talk about hydroelectric plants, we have to talk about their storage of energy: swamps. Currently, reservoirs in Spain are in Very good situation thanks to the stormwith a generation capacity of 60.90%. In other words, reservoirs have A large amount of energy storedaccording to Miteco data we would be talking about a Total capacity of more than 17,000 MW.
To see it with data, the reservoirs have increased their volume by 296 HM³ (1.7% more). In the case of the Alcántara reservoir, One of the great batteries of Tajohas accumulated 257 hm³ of water in a week, which is equivalent to 454 GWh of electricity.
Conflict of interest. Although there is an increase in hydroelectric generation due to rains, there is a problem with the Reservoir management. Hydroelectric plants have an economic interest in maximizing their production, which can lead them to make decisions about water unworthy. These cases have even occurred when water reserves should have been used for another use, such as Agricultural irrigation. It will remain to see how companies They store and release water.
Forecasts In these days of intense rain and with the arrival of spring we will have to add the thaw of the mountains, so the reservoirs are expected to continue filling. This situation will ensure an even greater hydroelectric production capacity in the coming weeks, prolonging the low price phase. Hopefully enough to be extended, while in the European Commission they solve the issue of Down 5% to VAT In the light invoice.
