Solar power plummets in Alberta at suppertime

1. What’s going on at Travers TVS1 wind farm? AESOP reporting net generation in excess of max nameplate. Never happen.

   1. It’s not really much in excess of nameplate (466 vs 465). I did note that today Travers Solar today dropped from 465 MW at 14:09 to 38 MW at 14:40 so it lost 92% of capacity in the space of 1/2 hour. Not good and an example of just how volatile this kind of generation is. Travers has had some bad days lately looking at the data (Aug 5, 9 and today). Actually all the solar generation in SE Alberta has been behaving badly today. I think some of this erratic solar generation is why they are doing unusual things with the battery banks. Normally they just spike up and right back down to solve some frequency issue, but I’ve seen them lately running for 15 minutes or 1/2 hour at steady output, not their full output though, or they’d probably catch fire.

2. Correction – Travers Solar.

3. They’re less effective at night too.

   1. Yee of little faith.

4. This in summer. Imagine how effective it would be in winter.

5. See, Jenn? Over and over and over again. Just like you said.

   Did you use any electricity around suppertime last night? You can thank coal & natural gas for that.

6. More jibba jabba from the resident troll.

7. Just a reminder that solar panels lose efficiency and can be damaged in “hot” weather.

   Even the WEF knows this. Solar panels lose efficiency at the rate of 0.5% for each degree in temperature. Solar panel ratings are tested at a max temp. of 77 deg. F. Hahahaha ha ha ha … so your solar panel loses at least 10% efficiency if the temp. is 97 deg. F … a rather common summertime temp. throughout the inhabited world (no, it’s NOT “extreme weather”). So … good luck with those solar panels getting damaged and losing efficiency in the summertime sunshine. Oh! And they’ll become effectively USELESS after 10-20 years of service … speaking of “renewable” energy.

8. I miss John Cross – at least he made an effort when he trolled.

9. Just wait till Bill Gates start dimming the sun. My guess for the unintended consequences of this if it actually works will be less wind in addition to less sun. Lose lose.

10. Meh. Just eat supper early and problem solved. Mind you, in winter suppertime would be around 12 noon (assuming cloudless days – otherwise go hungry).

11. Pure projection, Demo.

12. “You are completely “in the dark” when it comes to how solar systems are managed. ”

    Go look at how badly these solar systems are all doing today. Note my example above of Travers (the big one) going from 100% of capacity to 8% in 1/2 hour. This raises serious issues for the grid when you lose 430MW in 1/2 hour. Worse yet are some of the small solar stations. Clydesdale1 went from 100% to 0% in the period 10:17 to 10:21 or 4 minutes. Luckily it’s a small solar plant (40MW) but it should never go to zero that fast indicating that these rapid changes cloud cover are causing issues with the inverters. Between 14:40 and 15:05 Clydesdale 2 went from 34MW to 2MW, so a loss of 94% of capacity in less than 1/2 hour.

    As they say not good, and the real problem is we have on the books gigawatts more of solar, meaning it’ll have the capacity to wreak complete havoc on the grid.

    Thankyou Daniel Smith for putting a pause on this craziness.

    1. Hmm, Amazon supposedly bought all the Travers generation. How’s that working for them?
       Ask the Washington Post?

13. You are as dumb as a bag of rocks and less useful.
