Boni Tunnel Energy-Efficiency Lighting System Project
PNOC Renewables Corporation provided 128 units of 50 Watt-peak solar photovoltaic (PV) modules to the Department of Energy as part of its contribution to the Boni Tunnel Solar-Powered LED Lighting Project. The project is an initiative of the Department of Energy (DOE) and the Department of Public Works and Highways (DPWH) towards reducing the energy consumption in metro tunnels that required 24/7 lighting.
The Boni Tunnel, a 280-meter long tunnel that traverses EDSA in Mandaluyong City along Boni Avenue, was known to be the most dimly-lit tunnel in Metro Manila. Its old lighting system consists of a mix of tubular fluorescent lights and high pressure sodium lamps with a total power demand of 6.6 kW resulting to an average utility cost of about Php 570,000 per year.
With the installation of LEDs, the total power requirement is down to 4.1 kW, a 40% reduction. This equates to a utility cost of about Php 360,000 per annum. However with the solar energy supply, only an average of 3.4 kW will be sourced from the grid thus further reducing the electricity cost to about Php 300,000 a month or almost 50%.
The Project was inaugurated on 15th May 2012, a year after the signing of the Memorandum of Agreement among the participants:
- Department of Energy as the overall coordinator for this joint undertaking;
- Department of Public Works and Highways for the design and construction of appropriate infrastructure;
- Metropolitan Manila Development Authority which provided manpower and equipment, and traffic management during the installation of the LEDs and the solar power facility;
- Mandaluyong City Government, as the beneficiary of the Project, shall operate, maintain and secure the entire installation;
- Philips Electronics and Lighting, Inc. which provided the appropriate lighting design solution and lighting products (LEDs);
- Asian Development Bank which provided the lithium ion batteries and other peripherals needed for the solar power system; and of course
- PNOC Renewables Corporation for the solar PV modules.
As Mayor Abalos said, “This is a historic project, combining LED lighting with solar power.” Indeed, it is the first of its kind in combining not only renewable energy and energy-efficient technologies but public and private strengths as well.
