How much money (estimated)was lost during this outage?

So you think there would be someone out there calculating the losses from the outage even while places continue to be out of power. And you think that person will have that figure within hours of the event....in this country. You really are quite dense.

What you jump on the man back for?

He asked a damn good question. You are a typical example of jumping on a horsie backwards. He never said anything about calculating during the blackout.

Calculating losses in an event like this is sorely needed in T&T. Problem is that the people who can do it will ask you to pass some serious change first.

The best we will get are guesstimates.

If memory serves, blackout was a term used in WW2 when people had to draw their curtains and out their lights so the enemy could not identify anything during air raids. If memory serves.

[bluefete]

Today is the day the PM said all public sector workers have to be vaccinated or else. I guess the message was sent.

T&TEC, TSTT (people with landline phones = no service with the 21st century wireless when electricity goes) and WASA - NO SERVICE.

Make it make sense.

Sis. Devi came here after 2013 or what?

This is the 1st nationwide blackout? Or is she operating from India?

Saharan dust brining eggs? Riiiggghhhttt.

[The_Honourable]

Sister Devi is a crackpot.

2013 blackout happened late at night so by the time people wake up from sleep, it was already resolved. That event had conspiracy theories also of who hear what and what Kamla was doing in powergen penal.

Utility companies need to figure out a strategy in dealing with a catastrophic loss of electricity supply. All it takes is for the Union Estate 220 KV line to be interfered with and virtually everything goes down.

Doesn't mean the same thing in this context.

Did Tobago also have a black out yesterday ?

No. They are served by Cove estate power plant now

Hearing talk about planned outages for 9-3 but cant verify.

This made my morning
Also why I feel like blackouts will happen again. This country about 24 hours from caveman society.

***Disclaimer:
I do not work for TTEC/TGU/Powergen nor have i ever been employed by any of them (it was once a dream of mine to work for them though) and I'm open to any correction of inaccuracy in my post.***

In any utility scale electrical network there is transmission and distribution.
Power is transmitted at higher voltage (220kV, 132kV in this case) to minimize (I^2)R losses.
From the transmission grid there are connected various distribution networks (33kV, 12kV that i know of). Power is then finally stepped down (via pole mount transformers) from the distribution network to 220v (split phase for domestic use and 3 phase for light industrial use).

I'm no engineer, however based on my limited understanding of TTEC's transmission network topology, the Pt. Lisas estate was in the past serviced by 132kV. Assuming no infrastructure changes (new step up transformers) at Powergen in Pt. Lisas i would believe that when power is generated at that facility it enters the network at 132kV.
In the past (pre-TGU) TTEC's Transmission network operated at 132kV. This means Powergen POS (now decommissioned), Penal, Pt.Lisas and Trinity (formerly inncogen) all connected to the transmission grid at 132kV.

TGU's website mentions it feeds into the transmission grid via three 220kV feeders at the switchyard for the plant (They supply 720MW or 54% of the country's total power demand).
If TGU is outputting at 220kV and other producers are outputting at 132kV then there has to be transformer/s to couple both networks.

The press release mentions two 220kV lines tripping. If TGU provides 54% of the country's demand and u suddenly lose 36% (2/3) of the total demand (without time to bring online idle/spare generating units at other facilities) i assume that would pose either a underfrequency or undervoltage condition (due to excessive demand) to the other power producers (powergen, trinity).

AFAIK there is a SCADA (Supervisory Control and Data Acquisition) system TTEC has at Mt. Hope, however im not aware of the exact level of control that would afford.
If i were to venture a guess i would assume it would provide the functionality of connecting/disconnecting producers to the transmission system and "loads" (consumers) to the distribution system (via either Vacuum breakers or SF6 switchgear). It may also provide an overview of the output parameters (Voltage, current, frequency, KVA) of each of the independent producers.


I Would really like to see the RCFA for this outage (just for knowledge sake), though i doubt it may be aired publicly.

Anyhow back to theorycrafting.

It just shows that after Trillions spent in past decades we are still governed by idiots on all sides that keep TnT in a 3rd world state. Vanity projects with no improvement to any of our Infrastucture

i feel sorry for those koi\pet fish ppl who lost their fishes, u seeing it all over fb, i was expecting this to happen after d 1st few hrs

honestly d blackout wasnt a big deal for me, it was a bit boring so i took a 2hrs nap & jes lay down rather than sit in d dark & watch nothing beside d full moon light

whatever will happen will happen during these rare occasions so u jes have to roll with it once u have have food & water, only real worries is if bandits try to break in ur house ...

Nope. Everything reconnected automatically once power was restored.

Kois are that sensitive that they can't live in a pond without the pump/filter/air setup for 12 hours?

Oxygen gets depleted very quickly in tanks if you have a few fish. For all fish.

People does have to use tubes and blow air into it manually when they run out of power.

I wish T&TEC well in their investigation to get to the root cause of this latest black-out.
Indications seem to have existed at least since late Dec. when we suffered a less severe national outage, that something in the distribution network was in need of attention.
Our key service providers which includes T&TEC, WASA, and telecommunications entities seem to be weak as far as risk management and preventative maintenance models presently and with our present financial challenges the outlook seems quite unfavourable.
The present minister whose portfolio requires oversight of many of the entities does appear quite committed to improving our circumstances , but he may find results difficult to achieve. I however hope he can get things moving in the right direction.

There are also battery powered air pumps

Had to do this same exact thing last night with my aquarium.Luckily,all the fishes are alive

Any disturbance that affects the TGU plant, will have a cascading effect on the grid. TGU supplies the grid with approximately half of the power demand. The plant was not designed to deliver that power to the grid, hence there are only 3 feeders. Recall that the plant was designed to power a smelter, with excess power supplying the grid. The grid required additional infrastructure to transport this power, so the Union, Gandhi and Debe substations were built. This limits the interconnectivity to the grid, so any disturbances at these substations or interconnecting transmission lines, will lead to similar outages.

Probably woefully overstocked tanks. Bio filtration should handle the load for a day or two, but if it terribly stocked and poorly maintained, they'll likely deal with an ammonia spike if waste isn't removed.

My tank was fine.

[Chimera]

People might have backups automatic backups to last them a 2 of 3 hours....

If you reach home 6 or 8 hours after current cut....all your fish dead

I have had 6 Kois (2" and less) in a 30 gallon tank and they have gone a full day with no filtration and aeration when my mother unpluged extension cords.

As Vexx say over population of fish (total inches of fish per gallon of water) probably is a prime cause

Hmmm Stuart, Hinds and Gonzales. Expect lots of words but nothing of substance
