The Visayas grid received a significant boost on Friday, May 8, 2026, with the energization of the MGEN Toledo Battery Energy Storage System (BESS) in Cebu. This development supports the government's push for enhanced energy security and grid reliability.
First-of-its-Kind Facility in Visayas
Developed by Meralco PowerGen Corp. (MGEN) through its thermal subsidiary, Toledo Energy Development Corp., the facility is the first in the Visayas capable of delivering continuous rated output for two hours before recharging. The project's Phase 1 operations can deliver 25 megawatts and 56.44 megawatt-hours using advanced lithium-ion technology. This technology stores electricity from both renewable and conventional power sources through the Wholesale Electricity Spot Market.
Critical Role in Grid Stability
MGEN Thermal president and CEO Felino Bernardo stated, "The MGEN Toledo BESS is expected to play a critical role in supporting the stability of the Visayas grid and in advancing the energy transition. By helping manage fluctuations during peak and off-peak hours, the facility will contribute to maintaining reliable power delivery and improving overall grid resilience."
Government Encouragement for Storage Systems
The Department of Energy has been encouraging the development of battery energy storage systems and requires variable renewable energy plants with at least 10-megawatt capacity to integrate storage facilities. This requirement helps ensure grid stability and reliability as more renewable sources come online.
Call for Public-Private Cooperation
During the launch, MGEN officials highlighted the need for stronger public-private cooperation in achieving energy security and accelerating the transition to renewable energy. MGEN president and CEO Emmanuel Rubio emphasized that Cebu remains a key demand center in the Visayas and an important part of the company's portfolio.
"The energization of the Toledo BESS marks an important milestone for the Visayas grid and reflects MGEN's continuing commitment to support a more reliable, resilient, and sustainable energy system. We view this as a meaningful step forward for the region's energy system, and MGEN is proud to support Cebu's continued growth while helping power a better tomorrow," Rubio said.
