Overview

Meralco launched a program on the modernization of its streetlights in the Metro Manila service area in 1996.

This is part of the company's thrust to significantly improve its services to customers within world class standards. The importance placed on street lighting also reflects the company's continuing commitment to community service as a vital role in the improvement of motorist and pedestrian safety, peace and order, economic activities, and tourism activities.

The modernization program involves the conversion of the company's mercury vapor streetlights to the more effective type of high-pressure sodium, which is now predominantly utilized in most countries worldwide. The company created a Streetlight Office to manage the program. From mid-1996 to December 2000, some 78,263 streetlights were modernized in Metro Manila. The localities covered were Manila. Quezon City, Caloocan, Paraaque, Pasay, Marikina, Las Pias, Muntinlupa, San Juan, Mandaluyong, Makati, Pasig, Taguig, Navotas, Malabon and Pateros. The last nine localities were already saturated with sodium streetlights.
