| Electrical generation is a competitive market. It's the expected and even desirable outcome that only the most efficient producers will remain profitable. You're not just plugging in solar panels; you're competing with other companies to see who can plug in the solar panels more cheaply. And it's even plausible that ERCOT currently can't handle additional PV in whatever area the Roby parcel was in without adding BESS, although the person you're responding to has no idea if that's true or not, since neither they nor I knows where that is. The conclusion in the post: > Run five projects through the process simultaneously. Most will fail for reasons you cannot predict. With five, one might succeed. And switching to batteries instead of solar. Or at least solar plus storage. |

| ▲ | Dylan16807 17 hours ago | parent [-] | | I didn't even say profitable. He can't get the ability to just hook up all the panels. | | |
| ▲ | kragen 17 hours ago | parent [-] | | He did get that ability. They just won't let him produce over 3 megawatts, making the plant unprofitable. It's a total clusterfuck. | | |
| ▲ | Dylan16807 17 hours ago | parent [-] | | That's a really pedantic answer. He can't properly hook up the panels. | | |
| ▲ | kragen 17 hours ago | parent [-] | | That's a simply incorrect answer. BESS, simple curtailment at peak hours, or angle diversity would solve the problem. If he'd known the problem was coming 18 months ago, it wouldn't be a problem. | | |
| ▲ | Dylan16807 17 hours ago | parent [-] | | > That's a simply incorrect answer. Okay, how small of a connection would they have to restrict him to for me to be correct? > BESS, simple curtailment at peak hours, or angle diversity would solve the problem. That much extra curtailment is a major problem. That much extra angle diversity hurts output. Batteries are a workaround for not being able to properly hook up the panels. | | |
| ▲ | kragen 17 hours ago | parent [-] | | You'll have to do your own calculations based on your own site data. Onsite BESS permits you to not only get by with a smaller hookup but also sell your energy at times when people are willing to pay for it. | | |
| ▲ | Dylan16807 17 hours ago | parent [-] | | > You'll have to do your own calculations based on your own site data. I did my calculation already. It said that a 1/3 drop in hookup for panels that were already hookup-constrained is not a proper hookup. Straightforward math. | | |

| > Oh come on. He was doing it for the tax credits. Without the tax credits, this project wouldn't have come close to making sense. |
| |
| ▲ | Dylan16807 17 hours ago | parent [-] | | The tax credits aren't coming out of the grid somewhere else. The project is a negative to tax revenue, positive to the grid, and positive to CO2 levels. | | |
| ▲ | baking 15 hours ago | parent [-] | | He's using the tax credits to undersell projects with storage that would have been more positive for the grid. Solar without storage in Texas is coal to Newcastle. Subsidizing bare-bones solar is not good for the grid. | | |
| ▲ | zekrioca an hour ago | parent | next [-] | | Because they don’t want to upgrade the grid, don’t want to compromise even in flexible cases, and want to keep everything as is. | |
| ▲ | Dylan16807 14 hours ago | parent | prev | next [-] | | Projects with storage can take advantage of the cheaper solar power by shifting their balance, installing fewer panels and more storage. This leaves the grid better off overall. | | |
| ▲ | baking 3 hours ago | parent [-] | | Projects with storage can also take advantage of lower grid connection power limits because they are not forced to dump maximum power at peak supply times of the day. |
