Fuel Lighting Optimization for Safety & Efficiency
In 2026, Uni Power Tech (UPT) Power Plant implemented a lighting improvement project in its fuel storage building by replacing the existing lights with more energy-efficient alternatives. The initiative aims to improve electricity efficiency while providing a more suitable and well-lit working environment.
The new lights consume less power per unit while delivering higher luminous output than the previous lights. Their improved lighting efficiency also reduces the number of lights required to illuminate the area, supporting more efficient electricity consumption while enhancing workplace visibility, particularly in areas with insufficient lighting or limited natural light.
Project Implementation
The company replaced the existing lights, which had a power rating of 276 watts per unit, with new lights rated at only 150 watts per unit. A comparison of their performance is presented below.
| Existing Lights | New Lights | |
|---|---|---|
| Wattage | 276 W | 150 W |
| Luminous Flux | 15,120 lm | 28,500 lm |
| Luminous Efficiency | 54.8 lm/W | 190 lm/W |
The comparison shows that the new lights consume approximately 45.65% less power per unit while providing approximately 88.49% higher luminous output than the existing lights. Their higher luminous efficacy also enables greater illumination with fewer lighting units.
Project Results
To date, the company has installed 16 new lights. The lighting system upgrade has reduced electricity demand by approximately 2.02 kW, equivalent to a 20.32% reduction, and is expected to save approximately 17,660.16 kWh of electricity annually. These results demonstrate improved energy efficiency and reduced electricity consumption in the company's operations.
In addition to energy savings, the upgraded lighting system provides better illumination and visibility throughout the fuel storage building, enabling employees to see their surroundings and potential obstacles more clearly. This improves working convenience and helps reduce risks associated with inadequate lighting, contributing to a safer working environment.
Future Direction
The company will continue monitoring and evaluating the upgraded lighting system in terms of energy consumption and lighting adequacy within the working area. The results will support the evaluation of project performance and consideration of similar improvements in other areas, where appropriate, with a continued focus on energy efficiency and workplace safety.
