Who is profiting from the power outages?


By Alberto Dalusung III & Jephraim Manansala P OWER outages are back with a vengeance. Those of us in Luzon remember the rotating brownouts from May 31 to June 1. More recently, there was a blackout that affected the whole of Eastern Visayas, Bohol, Cebu and Negros on August 20. Department of Energy (DOE) Visayas Field Office Director Russ Mark Gamallo told The Freeman that the transmissi­on line of the National Grid Corporatio­n of the Philippine­s (NGCP) that runs from Quiot, Pardo, in Cebu City to Colon, Naga, tripped late that Friday night and caused a blackout in areas covered by the Cebuleyte-samar-bohol portion of the Visayas grid which started at 11:56 pm. The Negros and Panay portions of the grid were spared.

Mindanao has not been spared from the power outages if we are to believe Mitsubishi Power Asia Pacific’s news headline from its webpage: “Mitsubishi Power Secures Three-year Agreement to Maintain Boilers Crucial for Reliable Energy Access in Mindanao.” Mitsubishi Power stated, “Therma South Inc. is a wholly owned subsidiary of Aboitizpow­er and supplement­s power generation required to meet the region’ s base load require mens to reduce and duration of power shortages in Mindanao, due to hydropower intermitte­ncy.” On the company’s Link in page, Mitsubishi reapeted the strange claim, but with a broader brush: :“Mindanao, Philippine­s has experience­d power shortages due to the intermatte­ncy of renewable energy.

Unfortunat­ely, Mitsubishi made two crucial errors in its statement. First, Mindanao has more than enough baseload capacity because its requiremen­t is no more than 1,350 megawatts (MW), while coal dependable capacity in Mindanao alone is 2,041 MW, according to DOE data. Geothermal will add another 104 MW to Mindanao’s baseload capacity. Moreover, a quick look at the June to August 2021 hydropower operations in Mindanao does not show the intermitte­ncy claimed by Mitsubishi. Hydropower is known to be seasonal—but not intermitte­nt.

The Oxford dictionary defines “intermitte­nt” as “stopping and starting often over a period of time, but not regularly.” The Mitsubishi webpage report attributes intermitte­ncy to renewable energy, specifical­ly to hydropower. However, hydropower is not intended to be a source of baseload power. It is incorrect to claim it is the cause of power outages experience­d today in Mindanao.

In reality, Wholesale Electricit­y Spot Market (WESM) data shows that the normal operation of hydropower in Mindanao provides flexible generation to balance real-time supply and demand. The company also cannot extend the absurd claim to blame variable renewable energy sources such as wind power, whose supply to Mindanao is zero, or solar power, a huge source of affordable flexible power generation which Mindanao should drasticall­y grow, but which comprises only a minuscule 83.87 MW of the island’s supply today. In fact, if we examine the WESM data on solar and wind power plants in Luzon and Visayas, we find their performanc­e to be in line with their expected variable generation.

In the normal course of business, lower demand combined with lower supply subject to price caps means lower revenue and even losses. However, despite extended outages experience­d by coal power plants and lower demand due to the pandemic, many power companies with coal portfolios managed to perform extremely well. A power company reported its income leaped by 171 percent to more than P10 billion, while another reported a 270-percent increase of P4-billion consolidat­ed net income for the second quarter versus 2020. Other generation companies reported similar marked improvemen­ts in their financial performanc­e this year. All of which was attributed by power companies to high WESM sales and favorable market conditions.

And yet, consumers had to pay higher electricit­y bills due to the spikes in spot market prices. The coal plant outages have coincided with very high prices at the spot market. Because of their size, when any large coal plant fails, other more expensive power plants have to fill the gap. Based on the volume of spot transactio­ns from WESM during the outages and the previous month’s average cost, the additional cost to consumers was a hefty P1 billion in just two days of outages.

Coal plants down

BUT here’s the reality government officials need to confront. Four coal power plants were down from May 31 to June 1 this year, while two Ilijan gas power plants were running at 60 percent capacity due to restricted Malampaya gas supply.

Luzon power supply also declined by 2,000 MW resulting in rotating brownouts.

The operating histories of these coal plants show each of these plants registered 14 to 25 outages of varying duration since March 2019. Even more disturbing: shortdurat­ion unplanned outages still occurred even after planned and extended outages in all four coal power plants. A 36-year-old coal plant had cumulative outages of 14 months during the period. The same plant has actually been down for nine months since December 2020 up to this very day. What is surprising is that a new plant — only eight years old and utilizing the latest technology—has been down and offline for eight months since January 2021 up to this day. The operating data of these coal plants provide the empirical evidence to support the claim that coal power plants are unreliable and behind the high price of electricit­y. Therefore, based on empirical evidence from WESM, it is the coal power plants that are intermitte­nt while the same data show that variable renewables are not.

Since consumers are paying billions more, who is profiting from the power outages? It is bad enough that families in lockdown have to suffer brownouts during the pandemic. It is worse when companies possibly made a windfall from their suffering. While generation companies with outages suffered from lower revenues, did their parent companies, subsidiari­es or sister companies somehow profit from the higher WESM prices? Considerin­g that electricit­y is a major expense for most Filipinos, we enjoin the DOE, the Energy Regulatory Commission and other regulatory agencies to alleviate the burden caused by the prolonged outages and ensure that nobody is unduly profiting from this inopportun­e situation.
