On Power Outages in the Philippines

by Alan S. Cajes, PhD

It seems that everyone is asking the question why is it that brownouts are occurring now, especially in the provinces. Our training participants asked that question when we experienced power interruptions recently in a training facility in Nueva Ecija. Five years ago or so, I would have an easy response to such questions given my involvement in energy projects then. So I decided to update my understanding of this issue today, as we celebrate Earth Day, since I’m also interested to know the carbon footprint of our electricity consumption.

Our total dependable capacity as of 2021 is 23,855 megawatts (MW) distributed as follows: 16,541 MW in Luzon; 3,333 MW in Visayas; 3,981 MW in Mindanao.

What is dependable capacity? Dependable capacity means the maximum capacity of power generation plants to meet the electricity demand and avoid power outages.

Is this dependable capacity sufficient? The answer is no, if you are experiencing power interruptions even in the absence of calamities.

What are the factors that affect dependable electricity capacity? The 1st factor is availability of fuels for power plants, such as coal, oil and gas. No fuel, no power. Expensive fuel, high cost of electricity. The 2nd factor is weather conditions that will affect solar, wind and hydro power plants. Less rainfall, low hydro power output. No sunlight, no solar power. The 3rd factor is emergency repair & maintenance. Machines with moving parts require regular preventive maintenance or repair when damaged. The 4th factor is demand from consumers. There are months when consumers use more electricity compared to other months, such as during the months of March, April and May. Consumers who do not use energy efficient appliances and do not practice energy conservation also contribute to spikes in demand.
So, power interruptions occur when demand exceeds dependable capacity? Yes.
If Visayas and Mindanao experience low dependable capacity, can we transfer excess capacity from Luzon to affected regions or provinces? No, if your area is not connected to the national transmission lines.

Can we increase dependable capacity by building power plants? Yes. However, proposals to build power plants go through the usual bureaucratic processes and encounter various risks, like political risks (permits & clearances), financial risks (funding requirements, interest rates & payback period), as well as project implementation delays due to pandemic, unfavorable weather conditions, etc.

How can affected provinces increase their respective dependable capacity? Option 1, work with concerned government agencies on how to connect to the national transmission lines. Option 2, develop new & renewable energy sources. Option 3, support the local electric cooperatives in their long-term power supply agreements and efforts to ensure grid resilience. Option 4, implement energy efficiency & conservation programs.

What can individual consumers do to help? First, invest in small solar, hydro, wind or biomass projects to support your electricity requirements (any excess power can be sold to electric distributors). Second, practice energy efficiency & conservation. Third, pay electricity bills on time. Fourth, participate in demand side management and related programs. Fifth, invest in companies that build & operate renewable energy power plants.
By practicing energy efficiency & conservation, we can also help in reducing our electricity carbon footprint, which is 73.9 Metric ton of Carbon Dioxide equivalent as of 2021.

Why did Japan invade the Philippines? How did the Filipinos delay the Japanese expansionism?

by Alan S. Cajes, PhD

On the events that led to the Fall of Bataan or the Day of Valor (Araw ng Kagitingan): A review of literature and a chat with ChatGPT

In summary, the Empire of Japan occupied about 25% of China’s territory by 1937 to exploit natural resources for Japan’s growing industries. To stop Japanese expansionism, the United States imposed economic sanctions, including an oil embargo that represented about 88% of the total Japanese oil imports. As a response, Japan invaded Southeast Asian countries, including the Philippines, which was under American occupation, to secure oil, rubber and other natural resources. But as a prelude to such invasion, Japan attacked Pearl Harbor on 7 December 1941 to cripple the capacity of the US to take part in the war. This assumption was eventually proven wrong.

ASC: Let’s talk about the War in the Pacific during the second world

ChatGPT: Sure, I can help with that. The Pacific theater of World War II was a major theater of the war that primarily involved the Allied powers against the Empire of Japan. The war in the Pacific began on December 7, 1941, when the Japanese attacked the U.S. naval base at Pearl Harbor in Hawaii, and ended on September 2, 1945, with the formal surrender of Japan aboard the USS Missouri.

The war in the Pacific was characterized by brutal fighting in some of the harshest conditions on earth, from the dense jungles of Papua New Guinea to the tropical islands of the Philippines. It was fought primarily by the United States and its allies, including Australia, New Zealand, and the United Kingdom, against the Imperial Japanese Army and Navy.

The war saw major battles, such as the Battle of Midway, the Battle of Guadalcanal, the Battle of Leyte Gulf, and the Battle of Okinawa, which were fought in some of the most remote and inhospitable regions of the Pacific. It was also characterized by the extensive use of naval and air power, as well as the deployment of new technologies such as submarines, aircraft carriers, and long-range bombers.

The war in the Pacific was particularly brutal, with both sides suffering heavy losses in both personnel and equipment. The Japanese were known for their fierce resistance and their willingness to fight to the death, which made the battles in the Pacific particularly difficult and bloody.

Overall, the war in the Pacific was a significant part of World War II and had a profound impact on the history of the region. It was a long and hard-fought conflict, and it saw some of the most intense fighting and strategic maneuvers of the war.

ASC: Why did Japan attack Pearl Harbor?

ChatGPT: The attack on Pearl Harbor by the Imperial Japanese Navy on December 7, 1941, was a surprise military strike against the United States naval base in Hawaii. The attack was a major turning point in World War II and led to the entry of the United States into the war.

There were several factors that led to Japan's decision to attack Pearl Harbor. One of the main reasons was Japan's desire to expand its territory and gain control of resources in Southeast Asia. At the time, Japan was heavily dependent on imported oil and other resources, and it saw the United States as a major obstacle to its expansionist ambitions.

Japan also saw the United States as a potential threat to its empire-building efforts in Asia, and believed that a pre-emptive strike against the U.S. Pacific Fleet would neutralize its military capabilities and enable Japan to pursue its ambitions with less opposition.

Additionally, Japan had been negotiating with the United States for months before the attack, seeking a peaceful resolution to their differences, but these talks had broken down. Japan's leaders believed that war with the United States was inevitable, and they saw the attack on Pearl Harbor as a way to gain a tactical advantage in the opening stages of the conflict.

Overall, the decision to attack Pearl Harbor was a calculated risk on the part of Japan's leaders, who believed that it was necessary to achieve their strategic goals. However, the attack ultimately backfired, leading to Japan's entry into a protracted and devastating conflict that would ultimately end in its defeat.

ASC: Why did the US declare an oil embargo against Japan?

ChatGPT: The United States declared an oil embargo against Japan in 1941 as part of a broader effort to put pressure on Japan to halt its aggressive expansionist policies in Asia. At the time, Japan was heavily dependent on imported oil to fuel its economy and military, and the United States was one of its primary suppliers.

The oil embargo was a response to Japan's invasion of French Indochina (Vietnam) in July 1941, which the United States saw as a threat to American interests in the region. The embargo was designed to restrict Japan's access to oil and other critical resources, with the aim of forcing Japan to abandon its expansionist policies and come to the negotiating table.

The embargo had a significant impact on Japan's ability to conduct its military operations, as well as on its economy. It forced Japan to rely on its own limited oil reserves, which were insufficient to meet its needs, and led to a deterioration of its military capabilities over time.

The embargo was also a contributing factor in Japan's decision to attack Pearl Harbor, as Japan saw the embargo as a threat to its national security and a sign of American hostility. The attack was intended to neutralize the American military threat in the Pacific and secure Japan's access to critical resources.

Overall, the oil embargo was a key factor in the lead-up to the Pacific War and had a significant impact on the course of the conflict. While it was intended as a measure to prevent conflict, it ultimately contributed to the outbreak of war between the United States and Japan.

ASC: Why did Japan invade the Philippines?

ChatGPT: Japan invaded the Philippines during World War II for several strategic reasons. The Philippines was then a U.S. territory, and it was seen by Japan as a key target for its plans to expand its influence in the Pacific.

One of the primary reasons for Japan's invasion of the Philippines was its desire to cut off the United States from its colonial holdings in Southeast Asia. The Philippines was a key staging area for American military operations in the region, and Japan saw its occupation as a way to eliminate this strategic threat.

Another reason for the invasion was Japan's desire to gain access to the Philippines' natural resources, including oil, rubber, and minerals. Japan was heavily dependent on these resources, and the Philippines offered an opportunity to secure them without relying on foreign suppliers.

Japan also saw the Philippines as a potential site for military bases and as a key defensive position in the Pacific. By occupying the Philippines, Japan could establish a beachhead for future operations in the region, as well as provide a buffer against potential American counterattacks.

Overall, Japan's invasion of the Philippines was part of a broader strategy to expand its influence in the Pacific and eliminate the United States as a military threat in the region. While the invasion ultimately failed, it was a significant campaign in the Pacific War and had a profound impact on the history of the Philippines and the region as a whole.

ASC: How did the Filipinos help in stopping Japanese expansionism?

ChatGPT: The Filipinos played an important role in resisting Japanese expansionism during World War II. Despite being a U.S. territory at the time, the Philippines had a large population of Filipinos who actively participated in the resistance against the Japanese occupation.

One of the key ways that Filipinos resisted Japanese expansionism was through guerrilla warfare. Following the fall of the Philippines in 1942, many Filipinos took up arms and formed guerrilla units to fight against the Japanese occupation. These guerrilla groups carried out a range of operations, including sabotage, intelligence gathering, and attacks on Japanese military targets. They also provided support to American and Allied forces in the region, who were able to use guerrilla intelligence to plan their own military operations.

In addition to guerrilla warfare, Filipinos also played a critical role in the intelligence effort against Japan. Many Filipinos worked as spies and informants, providing valuable information on Japanese military operations and troop movements. This information was crucial in planning Allied military operations in the Pacific and in disrupting Japanese expansionist efforts.

Filipino civilians also contributed to the resistance effort, providing support to guerrilla fighters and engaging in acts of civil disobedience against the Japanese occupation. This included distributing anti-Japanese propaganda, providing food and shelter to resistance fighters, and organizing protests and strikes against Japanese policies.

Overall, the Filipinos played a crucial role in the resistance against Japanese expansionism in the Pacific. Their efforts were instrumental in helping to disrupt Japanese military operations and in paving the way for Allied victories in the region.

ASC: What can you say about the Day of Valor or the Fall of Bataan?

ChatGPT: The Day of Valor, also known as the Fall of Bataan, was a significant event during World War II in the Pacific. It marks the surrender of approximately 76,000 Filipino and American troops to the Japanese on April 9, 1942, after a grueling three-month-long battle in the Bataan peninsula in the Philippines.

The battle of Bataan was a pivotal moment in the war, as it marked one of the first major victories for Japan in the Pacific and forced the Allies to reevaluate their strategy in the region. The fighting was intense and grueling, with Filipino and American troops enduring extreme heat, disease, and starvation as they fought to hold off the Japanese advance.

Despite the valiant efforts of the Allied forces, they were ultimately overwhelmed by the Japanese, who had superior numbers, weapons, and supplies. Following the surrender, the prisoners of war were forced to undertake the infamous Bataan Death March, in which they were marched for miles without food, water, or rest. Many died along the way from exhaustion, dehydration, and outright brutality from their captors.

The Fall of Bataan was a significant event in the history of the Philippines and the Pacific War. It marked the beginning of a long and difficult period of Japanese occupation of the Philippines, during which Filipinos suffered greatly under Japanese rule. The day is commemorated every year in the Philippines as a national holiday, to honor the bravery and sacrifice of the Filipino and American troops who fought in the battle.
