The Antonio Guiteras thermoelectric power plant, which went offline from the National Electric System (SEN) on the morning of Tuesday, could be back online by the evening of the same October 7.
The news was announced on social media by journalist José Miguel Solís, citing engineer Jorge Gómez, deputy production director of the largest unit block on the island, as the source.
In a first post on Facebook, Solís indicated that it was a failure in the automatic control protection that caused the exit of the largest unit block this morning.
The official source specified that it was "a malfunction similar to the one recorded last September, which caused the SEN to fail", but emphasized that on this occasion they managed to avoid the collapse.
Finally, he concluded that "they expect to be online before ten at night."
In a more recent post, José Miguel Solís clarified that, once the issue was identified, the startup process has already begun.
"It may take between two to three hours to try to synchronize the SEN again. This was just confirmed by engineer Jorge Gómez, deputy director of production at the largest unit block on the island," he concluded.
The Antonio Guiteras thermoelectric power plant, the most important in the country, went offline from the National Electrical System (SEN) on the morning of this Tuesday, as reported by the Electric Union (UNE) in a brief post on social media.
The UNE only stated that the Guiteras went offline due to a "boiler failure." The malfunction occurred at 9:28 a.m. (local time).
The worst part is that a couple of hours before the departure of the Guiteras from SEN, the UNE had reported the departure at 6:55 a.m. (local time) of Unit 6 of Energás Jaruco.
In that case, the stated reason was the presence of "sargassum in the entrance channel of the BC-4705."
Before the two incidents, the forecast for power outages today was 1,740 MW.
According to UNE, the service was disrupted for 24 hours yesterday and remained affected throughout the early hours of today.
The maximum impact due to generation capacity deficit yesterday was 1,765 MW at 7:40 PM, exceeding the planned demand.
The energy production from the 32 new photovoltaic solar parks was 3,271 MWh, with a maximum output of 591 MW during peak hours for this generation source.
At 6:00 a.m., the availability of the National Electric System (SEN) was 1,680 MW, while the demand was 2,730 MW, resulting in a capacity deficit of 1,082 MW. During peak hours, it was estimated that the impact would be 1,150 MW.
Before the departure of the Guiteras and unit 6 of Energás Jaruco, they were outside the SEN:
Outage: Unit 2 of the Felton CTE, Unit 3 of Santa Cruz, Unit 8 of Mariel, and Units 3, 5, and 6 of the Renté CTE.
Maintenance: Units 1 and 2 of the Santa Cruz CTE and Unit 4 of the Carlos Manuel de Céspedes CTE in Cienfuegos.
There were 307 MW out of service due to thermal constraints.
Problems due to fuel shortages: 54 distributed generation plants with 270 MW and 229 MW unavailable due to a lack of lubricants, resulting in a total of 499 MW affected by this issue.
For the peak, the recovery of 50 MW is estimated from distributed generation engines that are offline due to fuel issues.
With this forecast during peak hours, a supply of 1,730 MW and a maximum demand of 3,400 MW are expected, resulting in a deficit of 1,670 MW. If the anticipated conditions persist, a shortfall of 1,740 MW is projected during this period.
