WalterMart, one of the Philippines’ most recognizable retail groups, has taken another bold step toward a low-carbon future. The company has expanded its clean energy partnership with First Gen Corporation, securing 47 megawatts of geothermal power to supply 47 WalterMart malls, retail outlets, and hotels across Metro Manila, Central Luzon, and Southern Luzon.

Through this agreement, WalterMart reinforces its position as a retail leader embracing renewable energy at scale—sending a strong signal to other major chains that the shift toward green power is no longer optional, but strategic.

A Retail Giant Powered by Geothermal Energy

The 47-MW supply will come from the Unified Leyte Geothermal Power Plant, operated by Energy Development Corporation (EDC), First Gen’s geothermal subsidiary and one of the world’s largest producers of geothermal energy.

WalterMart Chairman Abraham Uypeckcuat emphasized that the partnership supports the company’s long-term sustainability framework:

“The commitment to clean power enables our malls to operate responsibly and efficiently, reducing our carbon footprint while creating a greener future for the communities we serve.”

The agreement covers a wide range of WalterMart-associated establishments, including:

First Gen President Giles Puno reaffirmed the company’s commitment to support WalterMart’s growth with reliable renewable energy.

“We are happy to support the WalterMart journey to power their community malls with 100% RE,” he said.

Solar + Geothermal: A Dual-Renewable Strategy

This is not WalterMart’s first step toward sustainability. The company began rolling out solar systems in its community malls in 2019. By the end of 2025, 25 out of 45 WalterMart malls will host rooftop solar installations totaling 27 MWp, helping the chain meet its target of sourcing 20% of its energy from solar.

Now, with geothermal added to its energy mix, WalterMart is adopting a dual-renewable approach that ensures:

  • 24/7 baseload power from geothermal
  • Peak-daytime generation from solar
  • Significant reduction in carbon emissions
  • Lower exposure to volatile fossil fuel prices

This model could become a blueprint for other Philippine retailers aiming for energy security and sustainability.

First Gen’s Expanding Renewable Portfolio

First Gen and its parent company, First Philippine Holdings Corporation, continue to scale their renewable portfolio. With more than 1,700 MW of geothermal, hydro, wind, and solar assets, First Gen remains one of the country’s foremost renewable energy providers.

Its subsidiary Pi Energy also supports commercial partners through:

  • On-site solar systems
  • Remote monitoring technology
  • Energy efficiency solutions

The WalterMart–First Gen partnership aligns with the Philippines’ accelerated push toward a clean energy economy—showing how private sector leadership can fast-track the country’s renewable transition.

Will Other Retail Chains Follow?

WalterMart’s decisive shift toward geothermal and solar sends a powerful message across the Philippine retail landscape.

Major retail groups like SM, Robinsons, Puregold, and Ayala-owned stores may soon feel greater pressure to mirror these sustainability commitments, especially as consumers increasingly gravitate toward brands that demonstrate environmental responsibility.

Whether for brand reputation, long-term cost stability, or corporate ESG compliance, the trend is clear: renewable-powered retail spaces are becoming the new standard.

Geothermal energy, in particular, offers a competitive advantage—providing reliable, climate-resilient, baseload power that supports 24/7 retail operations without the fluctuations of wind or solar.

Not the quiet of peace, but the quiet of pressure . It’s the silence of teams racing to commercialize before competitors arrive. The silence of founders balancing mission and survival. The silence of a clean energy industry that desperately needs success stories… but is still learning how to measure them. In this one-on-one interview, we explore what it really takes to build a geothermal-driven clean energy company in today’s market, from strategic decisions and funding discipline to leadership, ethics, and the painful sacrifices behind growth. 1)  Vision & Strategy: “Speed Is Everything” Q:   Teverra  has grown rapidly, but co...

Geothermal Power Play: Well Engineering Partners Takes Over Operations as Sproule ERCE Sharpens Advisory Focus

The geothermal energy sector is heating up literally and figuratively and a recent strategic move is set to accelerate progress in sustainable energy production. By: Robert Buluma Effective January 1, 2026, Well Engineering Partners (WEP) acquired the operational and production-focused geothermal activities from Sproule ERC (formerly associated with Veegeo). This acquisition marks a smart realignment of strengths in the booming geothermal market, where clean, reliable baseload energy is increasingly vital for the global energy transition. Imagine harnessing the Earth's natural heat to power homes, industries, and cities without the intermittency of solar or wind. Geothermal energy does exactly that, providing constant output from deep underground reservoirs. But turning that potential into reality requires specialized expertise from initial resource assessment to long-term well maintenance. That's where this deal shines: it allows each company to double down on what they do b...

The Billion-Dollar Gamble Beneath Our Feet: Why Geothermal Exploration Is the Industry’s Greatest Risk

Exploration Risk: The Billion-Dollar Gamble Beneath Our Feet By:  Robert Buluma Image credit: Kane Watikson on LinkedIn  Geothermal energy is often described as the sleeping giant of the clean energy transition  constant, weather-independent, capable of delivering 24/7 baseload power without the intermittency that defines solar and wind. Yet despite this extraordinary promise, geothermal remains underdeveloped in most parts of the world. The reason is not lack of heat. It is not lack of demand. It is not even lack of technology and not even  FINANCE ,  Whilst many will throw that policy card, but Alphaxioms is already future proofing that .  The real barrier lies several kilometers beneath our feet  in uncertainty. Exploration risk is the defining challenge of geothermal energy. Unlike wind turbines that can measure wind speeds before construction, or solar farms that can predict output from sunlight data, geothermal developers must make multimillion-d...

ORC and Next-Gen: Advantages and Opportunities in Design and Execution

ORC and Next-Gen: Advantages and Opportunities in Design and Execution By:  Robert Buluma In the rapidly evolving landscape of renewable energy, the Organic Rankine Cycle (ORC) stands out as a versatile and efficient technology for harnessing low-grade heat sources, particularly in geothermal applications. Unlike traditional steam-based Rankine cycles, ORC uses organic fluids with lower boiling points, enabling power generation from temperatures as low as 80-150°C. This makes it ideal for geothermal energy, waste heat recovery, and even solar thermal systems. As we push toward a net-zero future in late 2025, next-generation enhancements to ORC systems are unlocking new advantages in design and execution. These innovations address key challenges like fluctuating energy demands, resource variability, and scalability, paving the way for more reliable and cost-effective clean energy solutions. This article explores the advantages and opportunities in ORC and next-gen technologies. We'l...

7,000 Feet Deep, 338°F: The Game-Changing Sensor Revolutionizing Enhanced Geothermal Systems

Breakthrough in Geothermal Monitoring: Berkeley Lab's High-Temperature Seismometer Powers the Future of Enhanced Geothermal Systems By: Robert Buluma Image: Cape Station, Fervo Owned Geothermal Station  Geothermal energy has long been valued as a reliable, clean, and renewable source of power. It draws heat from deep within the Earth to generate electricity with virtually no greenhouse gas emissions during operation. Traditional geothermal plants rely on naturally occurring hot water or steam reservoirs, which restricts development to specific volcanic or tectonically active regions. Enhanced Geothermal Systems (EGS), however, represent a game-changing evolution. EGS engineers artificial reservoirs in hot, otherwise impermeable rock formations found almost anywhere with sufficient subsurface heat. By injecting fluid under pressure to create and propagate fractures, EGS dramatically expands the geographic reach and scalability of geothermal power, offering the potential for 24/7, c...
