Davao City to suffer five-hour rotational brownouts

DAVAO CITY (MindaNews / 09 April) – Consumers within the franchise area of Davao Light and Power Company (DLPC) will suffer rotational brownouts of up to five hours as the first 150-unit of the coal-fired Therma South Inc. was forced to undergo an emergency shutdown, the second this year, last Wednesday.

In its advisory Friday, the deficit in the power company’s franchise — Davao City, Brgy. Bincungan in Tagum City, and Carmen, Sto. Tomas and Braulio Dujali towns in Davao del Norte  — was still blamed on the reduced generating capacity of Agus and Pulangui Hydo Power Plants but worsened due to the shutdown of TSI 1.

The TSI 1 failed to boot up after a tree fell on Davao-Toril 138 KiloVolt (KV) transmission line 1 of the National Grid Corporation of the Philippines (NGCP) last Wednesday.

NGCP spokesperson for Mindanao Milfrance Capulong said the damaged transmission line was repaired on the same day.

The power firm placed the deficit at 103 MW, which translates to five hours of brownouts (20 MW supply lack is equivalent to one hour power outage).

From February 16 to 26, the TSI 1 was under a 10-day preventive maintenance shutdown to address the plant issues from recurring in the future while the TSI 2 underwent two shutdowns – the first an eight-day a corrective maintenance shutdown from January 26 to February 2 and the second on March 3 but went online on the same day.

DLPC has contracted 100 MW from the TSI 1 and TSI 2. The rest is delivered to more than 20 electric cooperatives and distribution utilities in Caraga, Cotabato, Sultan Kudarat, Sarangani, parts of Bukidnon, parts of Misamis and parts of Zamboanga Peninsula.

The average demand for DLPC’s franchise area averages 345 MW.

The DLPC’s contracted capacity with Therma Marine Inc. is 30 MW, Hedcor Sibulan with 38 MW, Hedcor Talomo with 3 MW and the WMPC with 15 MW.

The diesel-fed Bajada Power Plant supplies 26 MW while Interruptible Load Program, a measure wherein the industries and companies would de-load from the grid and run their own generator sets, saves 10 MW of power.  (Antonio L. Colina IV / MindaNews)
