Government says it was a knife switch which caused the general blackout
SD. Although there are diverse opinions regarding the justification or not as to whether the exit of a substation led to the complete collapse of the National Interconnected Electric System (SENI), the reality is that the blackout of last Saturday caused bother and desperation for a large part of the population.
Yesterday, the government offered a preliminary report on last Saturday’s general blackout, in which they establish that the origin was in a breakdown at Itabo Gas caused by the “detachment of a knife switch which made contact with the 138 kW bar.”
Roberto Rodriguez Marchena, the government spokesman, explained during a press conference the report sent by the executive vice president of the Dominican Corporation of State – owned Electricity Enterprises (CDEEE), in which he explains that with the grounding of the line the circuit breakers at the substations were triggered.
In the meantime the executive vice president of the Dominican Association of the Electricity Industry (ADIE), Milton Morrison, said that if there was a breakdown which caused the Itabo substation to exit the SENI there should have been a response that would shutdown circuits until the supply by the operating generation facilities could cover the demand.
“What should a robust electricity system, which had a safety and emergency system have done? It should have begun to apply what I have told you about reducing the load and begin to remove the demand in the same dimension as the generator which went off-line. Because if Itabo I and II were 250 MW, then at the same time they should begin to unload the demand in order to prohibit a total collapse,” he explained.
Joaquin Luciano, the president of the Consumer Rights Federation (Fundecom), said that the first thing they have to do (the government) is to tell the truth. This is first, because now there are two versions, one which says Itabo and the other which says the executive vice president of the CDEEE, then, for whatever reasons, an electricity system has to have energy in storage, backup energy, in reserve, for these cases.
The expert on energy issues, Bernardo Castellanos, said that this event should provide the authorities with a reason to undertake an exhaustive review of the protection and frequency regulation systems of the SENI, and determine what really happened regarding the blackout, which according to what he said, should not occur just because a substation goes off-line.
Yesterday they supplied 86% of demand
The government spokesman said that he talked with Bichara, and he was told that at midmorning yesterday they were supplying 86% of the demand for electricity in the country.
For his part, the director of the National Department of Investigations (DNI) Sigfrido Pared Perez, said yesterday that he did not have information regarding the cause of last Saturday’s blackout, and he said that it would be the technicians that determine what happened. After leaving the office of President Danilo Medina, he said that on principle they cannot speak of sabotage.
