DOE investigate NGCP

The Northern Negros Electric Cooperative has sought the help of the Department of Energy to act on what it described as “deafening clamors” of its electric consumers in northern Negros against the failure of the National Grid Power Corporation to provide immediate solution to continued power fluctuations in northern Negros, caused by solar power generation interconnections to its 69KV power lines.

The NONECO area of coverage has the largest solar power generation facilities with most of them connecting through its 69KV lines, its manager, Danny Pondevilla, said.

In his letter to DOE Secretary Alfonso Cusi, Pondevilla said NONECO was flooded by public clamor and outrageous complaints from member-consumers that they immediately took into consideration, only to find out that the cause of emerging fluctuations is the solar power generations interconnected to the cooperative's 69KV lines.

Under the Distribution Code, Pondevilla said it is the obligation of the NGCP to deliver correct voltage and maintenance of its transmission lines. But up to this time, it has done nothing to correct the problem, he added.

NONECO member-consumers, especially in San Carlos City, that is hosting several solar power plants in Negros Occidental, and neighboring areas, were complaining about the damage and losses they suffered due to long blackouts and fluctuations of power involving millions of pesos.

As stipulated in the impact system study, Pondevilla said NGCP admitted to him that solar operation may trigger power fluctuations. Despite this, he added, it still remains to be addressed.

NONECO has been initially blamed by its electric consumers for the frequent power interruptions, that turned out to be the fault of NGCP, he added.

“Your intervention and possible immediate investigation on the matter is very much appreciated for the benefit of NONECO's member-consumers whose agony to this mess remain un-acted”, Pondevilla, added in his letter to Cusi.

As a temporary remedy, Pondevilla suggested to the system operator of NGCP to limit the production output of solar to the power lines. This will at least help minimize the power fluctuations, while a lasting solution is being looked into, he added.*GPB
