Partial eclipse of the sun will be visible in Portugal in the morning. Strong drop in energy production gives rise to “challenges”.
Os Portuguese will be able to watch a eclipse parcial do Sol on the morning of this SaturdayMarch 29. A Moon will cover about 30% of the sun.
The phenomenon will be seen in the northern hemisphere, so It will be possible to see it throughout the territory of Portugal; the best site for observation will be in Azores.
The eclipse should be Between 9:30 am and 9:45 amreaching your maximum by 10h40. Must end up close to 11:30, thus lasting about Two hours.
José Augusto Matos, from the Department of Physics of the University of Aveiro, recalls that it is better to use “Proper equipment”, like “one dark glass ” or “some special glasses to see eclipses. ”
On the radio, the expert comments that the eclipse can also be seen the naked eyeBut it is necessary to “be very careful with solar observation because the sun is very bright and can easily cause eye damage.”
Effects on Energy Production
The partial solar eclipse will cause a 23% reduction in the production of the national electrical system Scheduled for that time, Ren-National Energy Networks said this Friday.
“The phenomenon will cause an estimated 560 MW generation loss [megawatts]which represents about 8.5% of consumption and 23% of the production of the national electrical system scheduled for this time, ”said REN, in a statement.
The company said that it has been in collaboration with the other European electric transport network operators, prepare The National Electric System (SEN) for the purposes of the eclipse that will occur on Saturday.
During the eclipse, REN estimates a Loss of 10 MW per minute and a recovery at the rate of 22 MW per minute“What will cause challenges Operational related to the balance between generation and consumption in Sen and with control of the deviation in the interconnection with Spain ”.
Thus, he explained, it will be necessary to allocate Additional reserves with water and/or thermal generation.
These estimated values do not consider solar production associated with some production units for self -consumption, which will also have an effect on increased consumption, stressed REN.
“This effect is also being estimated by REN and duly foreseen in consumer predictions for that day, in order to reduce and mitigate, in real time, the unexpected effects,” he said.
Among the “unexpected effects” are blackout or Supply Disturbances. It reminds you that, to avoid this, the power grid needs to deliver exactly the same energy that is being consumed.
REN is aware that times will emerge when solar energy production will fall rapidly, but soon after there will be a quick recovery of the energy sent to the network.
