Energy Management
Energy management is key to ensuring that EGCO Group can efficiently utilize existing energy resources while meeting our goals to protect the environment in all operational areas and support the transition to a decarbonized society. The Company has defined the Energy Conservation Policy as a framework to drive efficient energy management and ensure that energy conservation initiatives are being continuously implemented across our power plants. The Khanom Power Plant and EGCO Cogen Power Plant, for example, have both implemented targeted initiatives to promote energy conservation. At the same time, EGCO Group is committed to the development, research, and investment of innovative renewable energy solutions to reduce organizational carbon emissions, and prioritizes employee training to make certain that our people understand the importance of energy conservation and are equipped with the knowledge to implement energy conservation measures in the organization.
Energy Conservation Initiatives in EGCO Group’s Power Plants: Optimizing Inlet Guide Vane (IGV) Efficiency
KEGCO unit 4 has implemented an energy conservation initiative that improves the efficiency of its gas turbine.
In 2022, a digital inlet guide vane (IGV) optimization system was installed. The system helps control the rate of air entering the IGV at part loads in order to optimize efficiency. Through increasing exhaust temperature and heat energy, the system ultimately minimizes natural gas consumption and carbon dioxide emissions.
Benefits of the Project
- Increased electricity generation efficiency.
- Reduced fuel consumption.
- Reduced pollution.
Implementation Approach
- Install the digital system (modify logic control) to control the opening and closing of inlet guide vanes.
2022 Performance
Reduced natural gas consumption by 2,799 MMBTU
Generated additional revenues equivalent to 150 – 3,700 baht per hour through increasing inlet guide vane (IGV) efficiency
Avoided 148.10 ton CO2e of greenhouse gas emissionss
Installation of Solar-Powered Street Lamps at EGCO Cogeneration Power Plant
To support the Company’s policy to reduce energy consumption and to promote employee safety, EGCO Cogeneration Power Plant has installed solar-powered street lamps within its operational area, focusing especially on areas with limited lighting. In total, the Company installed 10 solar-powered street lamps, alongside batteries, that will generate and store electricity during the day and provide lighting in the selected areas during nighttime.
Benefits of the Project
- Reduced energy consumption within the power plant.
- Reduced greenhouse gas emissions.
- Increased employee safety within EGCO Cogeneration Power Plant.
Implementation Approach
- Install solar-powered street lamps with batteries to provide better lighting during nighttime.
2022 Performance
Reduced non-renewable energy consumption by 4,380 kilowatts
Avoided 10.95 ton CO2e of greenhouse gas emissions
Energy Conservation at Kaeng Khoi 2 Power Plant
In 2022, the Kaeng Khoi 2 Power Plant implemented initiatives to reduce energy consumption in the power plant, listed below.
- 22 400-watt high bay light bulbs were replaced with 200-watt high bay light bulbs.
- 16 250-watt street lamps were replaced with 20-watt LED street lamps.
- 35 air conditioners were replaced.
The Kaeng Khoi 2 Power Plant has continuously implemented energy conservation initiatives to increase energy efficiency in its operations every year.
Benefits of the Project
- Reduced energy consumption and production costs.
- Electrical appliances are maintained as fitting with their service life and can operate at the most efficient levels.
Implementation Approach
- Complete light bulb replacements within the power plant and in surrounding streets.
- Complete replacements for air conditioners within the power plant.
2022 Performance
Reduced energy consumption by 139,152.60 kilowatts through replacing high bay light bulbs and street lamps
Reduced electricity costs within the power plant by 537,129.04 baht through replacing high bay light bulbs and street lamps
Energy Conservation at the Quezon Power Plant (QPL) and the San Buenaventura Power Plant (SBPL)
In 2022, the Quezon Power Plant and San Buenaventura Power Plant worked to reduce energy consumption in their operations by replacing light bulbs within the Power plant with LED light bulbs. By switching to LED light bulbs, both power plants reduced their electricity costs and lessen environmental impacts caused by greenhouse gas emissions and mercury contamination from the light bulbs.
Benefits of the Project
- Reduced energy consumption and production costs.
- Reduced greenhouse gas emissions.
- Mercury contamination associated with the use of lightbulbs is reduced.
Implementation Approach
- Replace light bulbs within the power plant with LED light bulbs.
2022 Performance
Reduced energy consumption by 82,917.63 kilowatts through replacing light bulbs in the Quezon Power Plant and San Buenaventura Power Plant with LED light bulbs
Avoided 59.06 ton CO2e of greenhouse gas emissions through replacing light bulbs within the Quezon Power Plant and San Buenaventura Power Plant
Reduced electricity costs by 501,758.54 baht by replacing light bulbs in the Quezon Power Plant and San Buenaventura Power Plant
Installation of Solar Panels at Quezon Power Plant (QPL)
In 2022, the Quezon Power Plant (QPL) installed solar panels to provide lighting in areas lacking electricity in order to reduce energy consumption and improve lighting within the power plant.
Benefits of the Project
- Reduced energy consumption and production costs.
- Reduced greenhouse gas emissions.
Implementation Approach
- Install solar panels to improve lighting.
2022 Performance
Reduced energy consumption by 18,096.36 kilowatts
Avoided 12.89 ton CO2e of greenhouse gas emissions
Reduced electricity costs by 109,421.68 baht
Year 2021
Energy Conservation Project of EGCO Group’s Power Plants
Changing light bulbs to LED bulbs
Klong Luang (KLU) Power Plant, a subsidiary of EGCO Group, has set up energy conservation measures for electricity measures. In 2021, the power plant can replace streetlamps (250 watts) with LED bulbs (150 watts) to reduce energy consumption, avoid generating electricity and avoid Hazardous waste containing mercury. The total amount of 27 lamps that were replaced. The Energy consumption from LED bulbs was 4.05 kWh per year, a 50% reduction compared to pre-improvement power consumption and reduced expenses by 68,561.24 baht per year.
Quezon Power Plant Philippines, a subsidiary of EGCO Group, has established an energy conservation measure by replacing light bulbs with LED bulbs. As of December 2021, 74.83% of the light bulbs can be replaced, saving approximately 12,581.99 kWh and 123,017.87 PhP equivalent.
The lamp replacement project was able to avoid CO2 emissions by approximately 8.96 M TonCO2e.
Energy and Power Cost Saving from LED Lights Installation
Solar panels and/or windmills for lighting are installed whenever there are lighting needs at a remote location, areas with no power supply, or wherever possible.
Aside from generating savings in power cost, it contributes to avoiding CO2 emissions. As of December 2021, a total of 19,813.80 kWh with an estimated equivalent amount of PhP 193,725.47 were saved from the use of existing solar panels and windmills in lighting. The total power saved is also equivalent to avoiding the release of 14.11 M TonCO2e.
