New challenges for our (Brazilian) matrix
New challenges for our (Brazilian) matrix
A "slice" that has been growing systemically in our power matrix is associated with wind and solar sources.
To make them viable, the national integrated system needs to assume the load when these sources are not producing. For example solar at night.
It means that other consumers pay for the backup plants that are necessary so that those who would decide to contract solar have their supply serviced at any time.
And so extra costs are generated and transferred!
For countries that have - still - fundamentally thermal matrices - it may even be viable because the substitution of gas, coal or some other source potentially brings economic benefits.
But Brazil has hydraulics as its main source. So, in our reality, installing these "intermittent" sources bring significant additional costs.

The Energy Central Power Industry Network is based on one core idea - power industry professionals helping each other and advancing the industry by sharing and learning from each other.
If you have an experience or insight to share or have learned something from a conference or seminar, your peers and colleagues on Energy Central want to hear about it. It's also easy to share a link to an article you've liked or an industry resource that you think would be helpful.
