Philippines counting on 14.2-GW new power supply by 2030

Over 14,200 megawatts (MW) of new capacity are set to come online by 2030 to strengthen the country’s power supply, according to the Department of Energy.

Latest DOE data showed that renewable energy accounted for the bulk of committed projects between 2025 and 2030, totaling 11,625.32 MW.

Some 2,620.74 MW of new capacity, meanwhile, will come from conventional sources like coal, oil and natural gas.

Committed projects refer to those that have secured firm financial closure, are already under construction or have been awarded through the government’s green energy auction rounds.

For renewables, solar projects dominated the list with an aggregate capacity of 8,431.19 MW, followed by wind (2,233.24 MW), hydropower (836.38 MW), geothermal (74.22 MW) and biomass (50.28 MW).

These projects are aligned with the Marcos administration’s target of expanding the share of renewables in the energy pie to 35 percent by 2030 from the current 22 percent.

Among conventional sources, coal projects remained at the forefront, with a total capacity of 1,570 MW. Natural gas and oil-based projects are poised to contribute 880 MW and 170.74 MW of new capacity, respectively.

The Philippines is still heavily dependent on coal for power generation despite the government’s moratorium on new Greenfield facilities.

In fact, coal accounted for 62 percent of the country’s power generation mix last year, according to a 2024 report by the International Energy Agency.

While there is a strong push to deploy more renewables, the IEA noted that coal’s share in the energy mix is likely to only marginally decrease to 60 percent by 2027.

Aside from power generation assets, the government is also expecting reinforcements from committed battery energy storage system (BESS) projects totaling 594 MW.

A BESS facility stores electricity from power plants or the grid for various applications such as grid stability, energy efficiency and renewable power integration.

The DOE is counting on these projects to augment the country’s power supply amid rising energy demand.

Under the Philippine energy scenario, peak demand is expected to grow by around 5.3 percent annually until 2028.

Reinventing the Waterwheel

In the foothills of the Himalayas, a group of villagers hauled a sturdy metal waterwheel into place. Its horizontal blades soon caught the rushing water of the stream directly below it. The machine began to spin, and electricity began to flow.

The roughly 2-metre-tall waterwheel, installed in a village in Kashmir, India, was the result of years of design work and development by researchers at the Technical University of Munich (TUM) and partners.

“You have this continuous power flow,” said Michael Erhart, the chair of renewable and sustainable energy systems at TUM. “It’s not intermittent like the radiation of the sun or wind power.”

Waterwheels have been around for thousands of years. Formerly used to drive mechanical processes such as milling or hammering, they were a crucial component in the industrial revolution. Today, waterwheels connected to generators can produce zero-carbon electricity as they spin.

An Archimedes screw-style waterwheel was installed along the River Wandle in London in 2012. The 8.5kW system generates enough electricity to power 18 homes.

Some experts argue that greater adoption of electricity-generating waterwheels could help to decarbonise energy systems. For the Kashmiri villagers, their new waterwheel offered energy independence. It was installed alongside other renewable energy resources, including a microgrid, between 2022 and 2024.

Erhart’s colleagues had previously supported the deployment of a similar waterwheel in Nepal, as well as a demonstration prototype in Tegernsee, southern Germany.

Before the new waterwheel arrived, the community in Kashmir had to rely on a centralised electricity grid that often let them down. “They had power cuts of weeks or even months,” said Erhart. The renewable energy kit meant the village could now survive off-grid.

The climate crisis and bouts of extreme weather are putting additional strain on power grids in India and Nepal. Decentralised microgrids connected to a mix of renewables including solar and waterwheel devices could, in theory, help remote communities to become energy self-sufficient.

The generating capacity of such wheels ranges from about 300W to 1kW, according to Erhart, depending on the flow of water. During flooding, it is possible to set up the wheel so that torrents of water can bypass it, meaning electricity generation may continue uninterrupted.

Erhart’s instructions for building the waterwheel are freely available online. The cost of assembling one could come to as little as $1,000 (£819), he estimated.

Separately, another kind of electricity-generating waterwheel was set up in Northern Ireland recently. The historic waterwheel attached to an old mill in Co Fermanagh was fully restored and now provides electricity to a restaurant within the building.

The Tully Mill restaurant’s waterwheel outputs roughly 1.5kW, according to Patrick Drumm, group treasurer of the Killesher Community Development Association. The wheel powers about 10 strong outdoor lights at the restaurant, though Drumm added that the cost of installing the system was significant at about £49,000. The project was made possible thanks to funding from the National Lottery.

It would be advantageous to use waterwheels even more widely, said Gerald Müller at the University of Southampton. Müller said a handful of companies in Germany currently restore or build waterwheels for electricity generation. “I was talking to the owner of one [of those companies] the other day and he was saying his books are pretty much full for the next three years – interest has increased because of the rise in electricity prices,” he added.

Müller’s research indicates that the efficiency of waterwheels, in terms of converting water power into electricity, can be as high as about 85%, .

One possible downside of waterwheels is the risk they might pose to aquatic life. However, research indicates they have a minimal impact on fish, for example.

Müller said that besides supplying private homes and buildings such as restaurants or hotels, waterwheels could also power pumps designed to move water up hills and irrigate fields on mountainsides.

DOE: P72 billion needed for full Philippine electrification by 2028

The Department of Energy (DoE) said it is seeking P72 billion for its total electrification program, and estimated the economic benefit of providing power to the entire country at P315 billion.

On the first day of the US Embassy’s 16th Media Seminar on Monday, Energy Undersecretary Rowena Cristina L. Guevara said that the estimate for the funds needed to achieve total electrification covers the period to 2028.

“A portion of that budget will be taken out of a loan because we already have a budget allocated for total electrification — around P3 billion to P5 billion per year,” Ms. Guevara said.

“So that’s around P25 billion, and we need P72 billion … so we might need to borrow because we have a deficit and the budget cannot increase suddenly,” she added.

She said that the DoE is in talks with the World Bank and the Asian Development Bank (ADB) for the loan. The program will seek to build distribution lines, electrify remote barangays and sitios, and install home solar systems.

Ms. Guevara said that the department presented the program and its economic benefits to the National Economic and Development Authority and the Department of Finance last week.

“We presented to them our request, and they seem to be happy about the numbers that came out of our study, particularly the economic benefits,” she said.

“Nobody reported (the estimated economic benefits) to them before. So, because of that, we’re thinking of a possible loan from ADB or the World Bank and thinking of government appropriations through the Department of Budget Management (DBM),” she added.

According to the study, giving low-income families access to up to eight hours of electricity a day will boost their income by 17.9%, while their expenditure is expected to increase by 17%.

If access to electricity were increased to eight hours to 16 hours per day, income and expenditure are expected to increase by 33.3% and 33%, respectively.

If low-income families are given access to electricity for 16 to 24 hours a day, their income and expenditure are projected to increase by 49.4% and 52.2%, respectively.

“If we are able to do total electrification, the economic benefit (of) P315 billion… (is equivalent to) 1.8% of our gross domestic product (GDP),” Ms. Guevara said.

“And the total electrification program is just P72 billion. If you invest that but get P315 billion back, wouldn’t that be a win?” she added.

According to Ms. Guevara, more than 2 million households currently have no access to electricity.

The DoE estimates the current household electrification rate at 93.12% at the end of March, while the target for this year is 94.83%.

President Ferdinand R. Marcos, Jr. said in his State of the Nation Address last year that the target is to achieve full household electrification by the end of his term.
