MERALCO AND STMI INAUGURATE NEW SUBSTATION IN LAGUNA
ENERGIZING PARTNERSHIPS. One Meralco and STMI recently inaugurated the new La Mesa 115kV switching station and Gas-Insulated Switchgear (GIS) Substation in LISP 2, Calamba City, Laguna which will accommodate STMI’s projected increase in demand from 14MW to 20MW. Leading the inauguration were (in photo L-R) Meralco FVP and Chief Commercial Officer Ferdinand O. Geluz, STMI VP and General Manager Yong Suk Kwon, and Meralco SVP and Head of Networks, Ronnie L. Aperocho.
The Manila Electric Company (Meralco) together with STMicroelectronics Inc. (STMI), the largest European semiconductor contract manufacturing and design company in the country, recently inaugurated the new 115 kV Gas-Insulated Switchgear (GIS) substation located at Light Industry and Science Park 2 (LISP 2) in Calamba City, Laguna.
The new substation will facilitate the upgrading of STMI’s electric service from 34.5 kV to 115 kV and accommodate its growing demand, which is projected to increase to 20 megawatts (MW) by 2027 from 14MW last year.
The substation houses one (1) 115 kV High-Voltage Gas-Insulated Switchgear, two (2) 30 MVA Power Transformers, one (1) 4.16 kV Medium-Voltage Switchgear, two (2) 750 kVAr capacitor banks, and various protective devices.
Meralco also recently commissioned the new La Mesa 115 kV Switching Station, also within the LISP 2. This project, which will improve the system reliability and power quality in the area, consists of a gas circuit breaker, three (3) sets of disconnect switches, and standard connection and metering facilities for the Philippine office of STMI.
“These projects are expected to address not only the limited power supply of ST Calamba, which is one of our highest operational risks, but also our future power supply demand, our power quality, our carbon neutrality strategy, and will definitely improve our site power resilience,” STMI Vice President and General Manager Yong Suk Kwon said.

Meralco First Vice President and Chief Commercial Officer Ferdinand O. Geluz, meanwhile, urged companies to work closely with the power distributor for their various energy requirements.
“Through our dedicated relationship management teams, Meralco works hand-in-hand with its Enterprise customers to identify and tailor-fit solutions that will ensure reliable power for their operational requirements,” he said.
This is also testament to Meralco’s commitment to support industrial customers, which play an important role in the country’s economy, according to Meralco Senior Vice President and Head of Networks Ronnie L. Aperocho.
“This new STMI Substation along with our new La Mesa Switching Station is designed to support the growing power requirements of STMI’s Philippine office through the delivery of safe, adequate, reliable, and high-quality electricity service which is consistent with our commitment to our more than 7.6 million customers,” he said.
The timely energization of these electric distribution facilities was made possible by the collaboration of One Meralco through its subsidiaries MServ, one of the largest energy service companies in the Philippines, and MIESCOR, one of the country’s leading service providers of engineering, construction, and maintenance service.
