“Severe blow to the SEN”: Cienfuegos Thermoelectric Plant will take three months to incorporate

SLP, Mexico.- The two units of the Carlos Manuel de Céspedes Thermoelectric Power Plant (CTE)from Cienfuegos, which left the National Electric System (SEN) last December for “intensive maintenance”, it will take at least three months to generate electricity again.

This is a “severe blow to the SEN,” according to the regime’s official press, since units three and four generate a total of 316 megawatts.

José Osvaldo González Rodríguez, general director of the CTE, explained to Granma that several elements of the turbine have been “intervened.” “That is a very complex job and it takes time. We estimate that part of it should be completed by the end of January; and in mid-February, the other,” he said.

Afterwards, they will begin to assemble the turbinewhich the manager described as “the critical route for Unit No. 3” and the process is expected to conclude in the first half of April.

“The fundamental objective is that Unit 3, when it synchronizes, with its 158 MW, which is its nominal power, can regulate the SEN frequency, and have the reliability that the System blocks have always had,” he contributed.

However, the other unit in maintenancenumber four, has damage to the boiler and would take longer to reconnect to the SEN.

When leaving the system, the superheater and reheater were misaligned, which had caused pipe failures. “The magnitude of the work is enormous.”

In unit four they plan to replace the exchangers associated with that failure, which could lead to “having a boiler in much better condition.”

After getting the pipes ready, maintenance will be carried out on the auxiliary equipment: the block transformers, the generator and the turbine, and the unit would finally be reincorporated into the SEN in the first half of June.

The two units of the CTE of Cienfuegos had not left the system since the general fall of the SEN on October 20.

When reporting the disconnection of the units in December, the directors of the thermoelectric plant announced that they aspired to first complete the repair of Unit 3, which would go through a process of cleaning ducts and eliminating sediments and mussels that affected the flow of water. of sea for cooling.

In Unit 4, on the other hand, there would be a more in-depth repair, they announced then. Maintenance would be carried out on the economizer, exchangers and turbine.

With these blocks not providing electricity, plus units 2 and 3 of the CTE Santa Cruz outside the SEN, as well as unit 5 of the CTE Renté and with a limitation in thermal generation of 214 MW, the electro-energy reality of Cuba is critical.

For this Friday, the Unión Eléctrica forecasts an availability of 2,165 MW compared to a maximum demand of 2,900 MW, which will generate an impact of 805 MW during peak hours.
