The energy landscape in the Philippines is changing fast. With growing awareness about sustainability, energy efficiency, and cost control, more businesses are exploring Retail Electricity Supply (RES) as a smarter energy option.
If you’ve ever wondered whether now is the right time to switch, 2025 is shaping up to be the perfect year. Here are the top 5 reasons to switch to RES in 2025 to help your business reach its full potential.
Retail Electricity Supply (RES) allows eligible businesses to choose their electricity supplier, much like selecting your internet or mobile plan. It’s part of the Electric Power Industry Reform Act (EPIRA), which was created to open the electricity market to competition.
In simple terms, RES lets you shop for electricity from different suppliers instead of being tied to a single utility. These suppliers, called Retail Electricity Suppliers, compete to offer better rates, flexible plans, and improved customer service.
However, it’s important to note that the actual electricity still comes from the power plants or energy generators that supply traditional Distribution Utilities (DUs).
What changes under RES is who you buy your electricity from. Instead of purchasing through your local DU, you buy directly through a different supplier that sources energy from a mix of generators.
This setup creates a more competitive market, giving businesses greater choice, transparency, and control, while ensuring the same reliable power flows through the existing grid.
Under the Philippine energy plan, Retail Electricity Supply (RES) operates through the Contestable Market, where qualified businesses can buy electricity directly from licensed suppliers.
The Retail Competition and Open Access (RCOA) law states that larger power users — those consuming at least 500 kW monthly — can already choose their preferred Retail Electricity Supplier (RES).
However, through the Retail Aggregation Program (RAP), smaller power users can also combine their electricity demand with other businesses in the same distribution area to qualify together and enjoy the benefits of open access.
Together, RAP and RCOA promote fair pricing, transparency, and energy efficiency across industries, helping drive progress and innovation in the Philippine energy sector.
One of the biggest advantages of switching to RES is cost savings. Since multiple suppliers compete for customers, prices are naturally more competitive. Businesses gain flexibility to negotiate contracts and manage electricity consumption strategically.
Energy efficiency is a national priority under the Energy Efficiency and Conservation Act. Through RES, companies can partner with suppliers who offer energy-saving technologies and data-driven insights. It’s not just about lowering your bills, it’s about building a culture of energy mindfulness across the Philippines.
One of the biggest advantages of switching to a Retail Electricity Supplier (RES) is the level of service and attention your business receives.
Unlike traditional Distribution Utilities (DUs), which serve large captive markets with little competition, RES providers actively compete for customers, and that means they go the extra mile to earn your trust and keep your business.
With a RES, you’re not just a number on a bill. You’ll have direct access to dedicated account support, faster response times, and clearer communication whenever you have questions or need adjustments.
From explaining your billing to helping you understand your energy usage, a good supplier ensures that you always have the information and assistance you need.
A customer-focused RES will always make things simple and transparent. Expect clear breakdowns of charges, straightforward contract terms, and no hidden costs, so you know exactly what you’re paying for. This clarity helps businesses make informed decisions and plan budgets confidently.
If you’re thinking about switching, look for a RES that offers support and open communication throughout your contract. The right partner won’t just supply power, they’ll help you power your growth.
Every company has its own rhythm, factories run around the clock, offices operate during the day, and logistics hubs peak at night. Retail Electricity Suppliers (RES) understand these differences and offer flexible contract options designed to match your energy use and financial goals.
You can choose between fixed-rate plans for stable, predictable costs, or market-based options that adjust with electricity prices and can yield bigger savings when rates are low. Some RES providers even offer mixed setups — a combination of both — to balance predictability and opportunity.
This flexibility gives businesses the power to design an energy plan that works for them, instead of being tied to a one-size-fits-all rate.
As your operations expand or your energy needs evolve, a flexible RES can help you adapt your plan, adding new sites, adjusting capacities, or revising your consumption targets without disrupting service.
The best suppliers act like true partners, helping you make informed choices and align your energy plan with your business strategy. Whether you’re scaling up or streamlining, flexibility means your power supply grows right alongside your success.
The Philippine Energy Plan (PEP) 2023–2050 serves as the Department of Energy’s roadmap for building a secure, affordable, and modern energy future. It focuses on three key pillars — energy security, accessibility, and affordability — while promoting the use of diverse energy sources and more efficient systems.
Part of this effort includes encouraging competition and innovation through programs like the Retail Competition and Open Access (RCOA) and the Retail Aggregation Program (RAP).
These initiatives allow businesses to choose how they buy electricity, supporting a more dynamic, transparent, and customer-driven energy market in the Philippines.
By switching to a Retail Electricity Supplier (RES), your business becomes an active participant in the country’s energy modernization efforts. You help drive the shift from a single-utility system to a competitive market that rewards efficiency and accountability.
This isn’t just about compliance, it’s about being part of a smarter, more responsive energy system. Every business that makes the switch contributes to shaping a market where customers have real choices, suppliers deliver better service, and the entire industry becomes more resilient.
In short, choosing a Retail Electricity Supplier isn’t only a strategic move for your company, it’s also a meaningful step toward a stronger, more efficient Philippine energy sector.
The future of energy in the Philippines is digital. Smart meters, automated energy tracking, and data-driven decision-making are reshaping how companies use electricity. RES providers are leading this evolution by integrating innovative tools for smarter management.
Beyond savings and flexibility, RES offers transparency and empowerment. By choosing the right provider, your business gains an energy partner, one that grows with you toward a more efficient future.
RES stands for Retail Electricity Supply, which allows contestable customers to choose their electricity provider.
Typically, businesses with high electricity usage (above the threshold set by the DOE) are eligible, though expansion to smaller users is also possible through the RAP.
By introducing competition, RES encourages suppliers to innovate, offering more efficient, renewable-based power solutions.
The country’s main energy sources include coal, natural gas, geothermal, hydro, and solar, diversely distributed across Luzon, Visayas, and Mindanao.
RES supports the government’s goal of energy independence, diversification, and renewable energy growth.
