Philippines accelerates push to light up rural homes

Over a million households in the Philippines remain without electricity, a gap the government aims to close within the next three years.

Energy Secretary Sharon S. Garin said the Department of Energy (DoE) and National Electrification Administration (NEA) are deploying a mix of strategies to speed up household energization, including microgrid systems, solarized homes, and streamlined grid connections.

“Just a little more and we’ll be close to 100%,” she said in a speech last year. “For every one peso the government spends on electrification, we get four pesos in return. So, it’s an investment for us and for our children.”

During his fourth State of the Nation Address in July 2025, President Ferdinand R. Marcos, Jr. directed the DoE and NEA to accelerate efforts to fully electrify the country before the end of his term in 2028.

As of June 2025, about 28.27 million households have been energized, accounting for 94.77% of the projected households from the 2020 Philippine Statistics Authority census.

Luzon posted the highest electrification rate at 98.53%, followed by the Visayas at 95.78%, while Mindanao continues to trail at 83.81%, highlighting the difficulty of reaching last-mile communities.

Under the 2024-2028 National Electrification Roadmap, the government was targeting a 96.51% electrification rate by the end of 2025.

The DoE’s Electric Power Industry Management Bureau (EPIMB) said achieving full electrification by 2028 will require an estimated P80.9 billion, with around P68.26 billion expected from government financing and P12.64 billion from private investments.

The funds will cover household connections to existing grids, distribution line extensions, stand-alone home systems, and microgrid projects.

NEA Administrator Antonio Mariano C. Almeda said the agency expected rural electrification to reach 91.7% by the end of 2025, aiming for 94% by the end of 2026 with higher subsidies from Congress.

“With the increase in the budget, it requires an increase in engineers to validate, inspect, liquidate, and issue certificates of final inspection,” he said during a briefing in December, noting that the issue is being discussed with the Commission on Audit.

EPIMB said insufficient funding and subsidies make grid extension and off-grid projects difficult, particularly in areas where electrification is not commercially viable.

“Because rural electrification is often not profitable, private companies are hesitant to invest. The regulatory and institutional frameworks—tariffs, subsidies, and incentives—may not sufficiently offset risk,” the bureau said.

Much of the work of electrifying last-mile communities has fallen to electric cooperatives and private utilities operating on the ground.

The Philippine Rural Electric Cooperatives Association, Inc. (PHILRECA), which represents cooperatives nationwide, said it is aligning its programs to support the government’s 2028 electrification goal.

“We are aligning all available mechanisms, projects, and assistance to ECs (electric cooperatives) in ensuring the attainment of total electrification by 2028,” PHILRECA Executive Director and General Manager Janeene Depay-Colingan said in a statement.

She noted that ECs face obstacles, including difficult terrain, limited infrastructure, high project costs, and logistical constraints, which require innovative and coordinated approaches.

PHILRECA said it is strengthening partnerships with government agencies, optimizing funding mechanisms, deploying modular and renewable energy solutions in off-grid areas, and enhancing the technical capacities of cooperatives.

MICROGRIDS, RENEWABLES

Manila Electric Co. (Meralco), which serves about 3% of the country’s land area, has also expressed support for the national agenda.

“The government’s target of achieving full electrification nationwide by 2028 is ambitious and critical for inclusive development — and Meralco is fully committed to supporting this agenda,” Meralco Executive Vice-President and Chief Operating Officer Ronnie L. Aperocho said.

Meralco is expanding its role in off-grid electrification through microgrid projects. The company targets to energize more than 1,000 homes and businesses on Cagbalete Island in Mauban, Quezon, with a solar-plus-battery microgrid system and backup diesel generation.

“With the launch of the Cagbalete Microgrid, we reaffirm Meralco’s commitment to power progress with sustainable energy solutions, ensuring that no one is left in the dark,” Mr. Aperocho said.

Renewable energy and microgrids are seen as cost-effective solutions for off-grid areas. Many households in remote communities rely on diesel generators or kerosene lamps, which often incur higher and more volatile costs.

“It offers a way to step back from traditional grid extension, reduce reliance on diesel and imported fuels, improve resilience — especially given the country’s exposure to natural disasters — and support inclusive development,” EPIMB said.

Albert R. Dalusung III, energy transition adviser at the Institute for Climate and Sustainable Cities, said that renewable energy can help lower electricity costs for local communities.

He cautioned that efforts should focus not only on expanding coverage but also on delivering reliable power that enables economic activity.

“I think what is important is not just to target full electrification because it may be ‘full electrification,’ but you’re only delivering eight hours or less of electricity,” he said.

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.
