User reviews
Extremely informative and easy to understand!
Great app
It does its job and tells us how much capacity is there
Nice responsive app as long as you have a good network connection. No annoying notifications (yet?)
I have used this app for a very short time but so far, it's very helpful and informative to try to understand what is happening with the management of our power grid and planned power shutdowns. I have recommended it to others.
Very helpful app. Great way to monitor potential for rolling outages during heatwaves.
