Energy Management 2022
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
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
