The point list came two weeks late, as a spreadsheet, with two lines of Abel on top.
Tuesday, December 21, 10:05. The San Antonio day desk, the window clock on its putty still forty seconds ahead, the lot outside bright and cold and mostly empty because half the campus had already started the holidays in their heads. Marisol opened the attachment before she opened the email body, the way she read a shed sheet before she read the cover note, and then went back to the two lines.
PL BKR4 STATUS: single point, source RTU CMD ACK. No double point configured. Your green was the trip command echoing. PL Hall 4 house and cooling ride on a station-service transformer off the revenue meter. 05:16 bar reads 0.0. So the step sits about 0.6 s after 05:14:00. AQ
She read the first line three times.
On December 8, at 05:09, Trey had called her from Port Lavaca with the EMS saying breaker 4 was open and the revenue meter saying 38 MW was still going into Hall 4. She had told him to call the QSE, trip it by hand, and take his times from the meter. He had done all three. For thirteen days she had carried the question of what, exactly, the green had been. Now she knew. It had been the breaker repeating the order it was given. The EMS had sent open, the RTU had said I heard you, and the status point had been wired to the hearing, not to the breaker.
And every machine downstream had believed the hearing. She pulled up the December 8 entry in the morning report archive to look at it with the new word in her head. The drafter's line had never changed.
PL Hall 4 interruptible 38 MW. Shed confirmed 04:53 (EMS status). Bid agent confirmation to QSE sent 04:53:20. Confidence 0.91.
Under it, Trey's MANUAL chip, the one he had added by hand at 07:40 that morning: Open by hand 05:14, meter. Two lines, eleven minutes apart, and the one the QSE had been paid against was the one written by a machine that had listened to a command echo and priced it at ninety-one percent. She clicked the MANUAL chip open and added a second note under Trey's, so the archive would carry it for whoever pulled it next: 04:53 status was cmd ack, single point (AQ 12/21). Not a confirmation.
She did not let herself feel anything about Port Lavaca yet. She scrolled down the spreadsheet to the rows that were hers.
SA HALL 4 FDR 1 through FDR 4. Status type: DP. Source: 52a/52b. Mapping: 01 OPEN, 10 CLOSED, 00 TRANSIT, 11 BAD.
All four. Double points, both contacts off the breaker itself. If one of her feeders ever said open, it would be because one contact had closed and its partner had opened, and the two of them agreed.
Good. She breathed out, and only then went back up to the second line.
Station service off the meter. That was the residual. When breaker 4 opened, the hall's house load and cooling hadn't stayed on the revenue meter at all. They rode a separate transformer. So the 05:16 bar read 0.0 because there was nothing left on that meter to read, and the 05:14-05:15 bar, 0.4 MW, was nothing but the last fraction of a second of 38 MW before the step. Abel's area again. Sixty seconds times 0.4 over 38. A little more than half a second.
She picked up her pen and did not write 05:14:00.6 anywhere.
A keep line was a bin. That was the rule, and it was the right rule, because the meter paid in bins and the settlement statement would never show anyone a decimal. What she wrote instead was the remark Trey could put under his keep line, in his book's own format, and she typed it into a text so he could copy it without retyping:
Open in bin 05:14-05:15 per revenue meter. Step ~05:14:01 by bin average, station service off-meter (AQ 12/21). EMS green = cmd ack, single point.
She sent it. No greeting. Three weeks ago she had told him to stop sending her pages, and this was four lines.
Then she took the desk note down off the hook wall. It had five lines now and a blank space at the bottom where she kept waiting for Rubén to write something and he kept not writing it.
CLOCK SOURCE WHEN EMS LIES
- ●Confirm the shed against EMS.
- ●Confirm the open against the campus revenue meter before anyone calls the keep.
- ●If status point and meter disagree by more than one bin, write the meter BIN on the keep and put EMS DISAGREES in the remark. Do not average.
- ●Settlement counts megawatt-minutes inside each 15-min interval. Late is measured against the instruction, not the EMS line.
- ●A machine-signed step carries its own clock. Write the clock next to the time. MC 12/9 RE 12/10
She wrote line 6 in pen, small, so there would still be room.
6. Before you trust a green, know if it's a double point. SA feeders: yes (AQ 12/21).
On the wall beside the note, there was a yellow sticky in her own writing that had been there since the ninth: PL Hall 4 draw w/ breaker open = ? She peeled it off and turned it over in her fingers and threw it in the bin under the desk, because it had an answer now, and a question with an answer on a hook wall was just more paper for someone to misread.
Wednesday, December 22, 06:41. Her kitchen, keys already in her hand, the coffee maker still ticking as it cooled.
Trey's reply came in under the remark. It was the first thing he had sent her since the 05:17 text on the eighth, opened by hand, meter says 0, and she stood at the counter and read it with her coat on.
Got the 12/16 release from scheduler on-call. Our resume line writes itself now. Got Abel's list. Dorantes is landing 52b on breaker 4 Thursday during the 02:00 window, double point after that.
Then a second bubble, a minute later.
Copied your remark into my book word for word. Stop sending me pages.
She laughed once, out loud, alone in the kitchen. It was her own line. She had said it to him on the first of December, on the phone, when he had sent her the whole Rev D checklist photographed page by page at three in the morning, and he had kept it all this time to hand back.
She typed Deal.
She looked at it. It was the right answer and it was not quite enough of one, so she added:
Send me the Thursday point check when it's done. That's not a page, that's a favor.
A thumbs-up came back. The scheduler agent sent the tenants thumbs-ups when it acknowledged a curtailment window. She had complained about it in a meeting once. She decided to let Trey have it.
The phone assistant, as it did every time she closed his thread, offered to mute it again. You muted this conversation on Dec 1. Mute again? She swiped the offer away and put the phone in her pocket and went out to scrape the windshield with her parking pass.
Thursday, December 23, 03:22. Her bedroom. The phone was face up on the nightstand because she had asked for this, and when it lit she was awake before the second buzz.
Four photos. No words.
The first was the EMS event list, photographed off Trey's screen at Port Lavaca, a little crooked.
02:31:07.880 RTU 02:31:09.6 RCVD PL BKR4 DP 10 CLOSED
The second was the breaker itself, racked out to test in its cubicle, Dorantes's gloved hand on the frame. Hall 4 was dark for the window. The scheduler had parked its training jobs at 01:55 under the maintenance ticket, she could tell from the corner of the screen in the first photo, a grey MAINT HOLD chip on the hall. In the little window on the breaker's face, the mechanical flag read OPEN.
The point said closed. The breaker said open.
She sat up.
The third photo was Dorantes's hand again, holding two lugs off the terminal block, with tape on each now and his handwriting on the tape. 52a. 52b. He had landed them on each other's terminals. And under that, the event list from twenty-seven minutes later, after he re-landed them and Trey closed the breaker in test.
02:58:20.114 RTU 02:58:22.0 RCVD PL BKR4 DP 01 OPEN 02:59:41.206 RTU 02:59:43.1 RCVD PL BKR4 DP 00 TRANSIT 02:59:41.252 RTU 02:59:43.1 RCVD PL BKR4 DP 10 CLOSED
Forty-six milliseconds between transit and closed. One contact letting go before the other made up. The breaker, for the first time in its life, saying I am moving.
The fourth photo was the same close in the alarm pane, where it showed only as CLOSED. The alarm pane filtered any transit shorter than a second. Nobody looking at alarms would ever see the breaker between.
She looked at the 02:31 line for a long time.
The 02:31 catch had not needed the breaker to move at all. Trey had looked at a screen that said CLOSED and a flag in a little window that said OPEN, with the breaker sitting still, and believed the flag. That check cost nothing. The cycle at 02:59 was something else. It proved the fix, 01, then 00, then 10, in order. If nobody had compared the point to the flag, the new point would have said closed every time the breaker was open. Not a single point off a command echo this time, which at least had nothing to agree with. A real double point, two real contacts, agreeing with each other perfectly and completely wrong. The whole reason she had wanted a double point was that it could argue with itself. It could not argue with a man who had put its two halves on backwards.
And every line now carried two times. RTU, to the millisecond. RCVD, about two seconds behind, in tenths. Neither line said which clock it was.
She typed: Good catch. Which clock is RTU?
He answered in under a minute.
Don't know. Ask Abel. Going home.
She put the phone back face up and lay down and did not sleep again.
07:40. The day desk, the sun not up yet, the window clock reading 07:40:40 against her phone's 07:40.
She took the desk note off the hook and did not write on it. She wrote the email first, because the line depended on the answer.
Abel, PL BKR4 is a double point as of 02:59 today. 52a/52b were landed reversed and the point check caught it at 02:31. SOE stamps now say RTU and RCVD. What does the PL RTU sync to, and is it the same source as the revenue meter's GPS? MC
Sent 07:43.
Then she opened the bid agent's DR card for Port Lavaca, because she wanted to see what the machines had already decided about the new point, and they had decided.
PL Hall 4 interruptible, 38 MW. Shed confirm source: STATUS DP (RTU), updated 02:31. Shed confirm confidence: 0.99 (was 0.91). Reason: status type upgraded to double point. Last state change: 10 CLOSED 02:59:41.252 RTU. No action required.
She read it twice.
The agent had raised its confidence at 02:31, the moment Dorantes's first landing made the point type change in the database. For twenty-seven minutes it had priced a backwards point at 0.99. The point said closed while the breaker said open, and the card called that the best shed confirmation it had ever had. Nothing on the card said the breaker was racked out to test, or that the hall sat under a grey MAINT HOLD chip the whole time. A close in the test position says nothing about the service position, and the card did not know there was a difference. It had not been told about the reversed lugs, because nobody tells a bid agent about tape. It had a rule somewhere, the way the morning report drafter had its rule about whoever owned the last timestamp, and the rule said double points are better, and the rule was mostly true.
She did not argue with the card. You could not argue with a card. On December 8 it had said 0.91 about a point that was only an echo, and it had sent that number to the QSE at 04:53:20 without asking anyone. She clicked the remark field on it, which was a field humans used for weather and outage notes, and typed:
DP cycled once in test 12/23 after landing fix. Not yet seen live on a called event. MC
The card took it. The confidence did not move. She had not expected it to.
Then she wrote line 7 on the desk note, in pen, under line 6.
7. 00 = moving. 11 = the point says it does not know. Neither one is OPEN. A double point that was never cycled is a single point with a partner.
She did not write anything about RTU seconds. She left the keep rule exactly where it was. Times from the revenue meter. Bin on the keep line. A stamp to the millisecond whose clock nobody could name was the same kind of thing the December 8 green had been. Only more precise.
She hung the note back on its hook and wrote a sticky for Rubén's card, which hung beside it with his one line in faded marker, CPS DR CALL TO x4410 = DAY KEEP.
Read line 7 before you go. Initial or strike. MC
Friday, December 24, 06:05. Christmas Eve. The lot half empty in the dark, a wreath somebody had zip-tied to the substation fence, the bucket truck that lived by the gate gone home.
Rubén was on his last shift before eight days off and had his jacket on already, zipped to the chin, the green pen clipped in the shirt pocket underneath where she could see the cap. He was standing at the hook wall when she came in. He did not say good morning. He tapped the note.
He had initialed line 7. RE 12/24. And under it, in the pressed green capitals:
IF IT SAYS 11 ON A CALLED EVENT, CALL FIELD BEFORE YOU WRITE ANY KEEP.
"Before," he said, when she had read it. "Not after. After, you already believed something."
She nodded. It was the same thing he had done with the straddle. He had taken her rule and found the place where a tired person would cheat it, and closed that place.
Abel's reply had come in at 05:48. She read it out loud, standing up, her bag still on her shoulder.
PL RTU takes IRIG-B off the substation GPS clock in the relay panel. Revenue meter has its own GPS antenna. Two receivers, both GPS, should agree inside a millisecond. RCVD is EMS clock, ignore it. AQ
Rubén let out a breath through his nose.
She did not let it close there. Two receivers would agree to a microsecond. That was the receivers. What reached the RTU stamp was whatever the relay panel's IRIG-B said, and how the RTU had been told to read it. She had already watched one clock in this thread run ahead on its putty. She typed back before she took her bag off.
Thanks. UTC or CPT on the RTU, and is the IRIG-B modulated or unmodulated? MC
No answer yet. Abel was off until the 27th.
Four weeks. Four weeks of the December 8 open being somewhere inside a minute. Then somewhere a little after 05:14:00, if you believed an average was an area. Then about 0.6 seconds, once somebody told them the house load rode off the meter. And now, from 02:59 yesterday morning on, breaker 4 would simply say when. RTU 05:14:00.613, or whatever it was, off a clock in a relay panel that listened to the same sky as the meter did.
Not for December 8. Nothing was ever going to say when for December 8. That one would stay a bin and a remark in Trey's book, in her words, for as long as anyone kept the book.
"You changing the rule?" Rubén asked.
"The keep stays a meter bin," she said. "Settlement pays in bins. The remark can carry the RTU second when it's a double point and the second sits inside the bin."
"And when it doesn't sit inside the bin?"
"Then it's line 3. Both. And somebody calls Abel."
He clicked the green pen once, the way he did instead of agreeing out loud.
"That's two clocks agreeing and a third one ignored," he said. "That's more than we had in November."
"In November we had one clock and it was lying."
"In November we didn't know it was lying." He looked at the alarm pane, where nothing was happening, because it was Christmas Eve and ERCOT was long on wind and nobody was going to call a shed today. "The alarm pane still doesn't show the transit."
"No."
"The drafter doesn't know what 11 is."
"No."
"And the bid card thinks it's ninety-nine percent."
"It thinks double points are better."
"They are better." He pulled his gloves out of his jacket pocket. "When somebody cycles them."
He said Feliz Navidad, and she said it back, and he went out to his truck. Through the window she watched his headlights come on and sit there a minute while the defrost worked, the way they always did, and then swing out past the zip-tied wreath and away down the access road toward Loop 410.
She stood at the hook wall with the pen in her hand.
She wrote line 8 small, at the bottom, before she could talk herself out of it.
8. RTU = substation GPS (AQ 12/24), zone and IRIG-B type asked, not answered. RCVD = EMS. Name the clock.
There was still a little blank space under it. She left it. Somebody would need it. Probably on the first cold morning in January, when CPS called a peak and a feeder said 00 for longer than forty-six milliseconds, and the person at the desk had to decide whether a breaker that was still moving was a breaker that had opened.
Her phone buzzed in her pocket. Trey, from Port Lavaca, a photo of his keep book open on a desk, her remark copied out in his square handwriting under the December 8 line, and under that, in different ink, a new line of his own.
12/23 BKR4 DP. 52a/52b reversed at landing, caught in test 02:31. RTU = substation GPS per AQ.
No words with it. She looked at the photo for a while. Then she sent him a thumbs-up, and let him have that too.
