Presentation on Cogeneration and District Cooling Plant MAKHOSTIA SDN BHD. KLIA Presentation on Cogeneration and District Cooling Plant (Kuala Lumpur International Airport)

MAKHOSTIA SDN BHD. KLIA INTRODUCTION The DCS Project at KLIA was secured through a bidding exercise in which 12 international consortium have participated. The construction of DCS Plant at KLIA was completed in April 1997. The initial capacity of the DCS Plant is 22,500 RT. The plant capacity is expected to be expanded to 35,000 RT in the year 2012. GDC(KLIA) was awarded a 20-year Concession on a BOT basis by the Malaysian Government. The DCS Plant has the capacity to produce both chilled water and electricity for sales.

DEFINITION OF DISTRICT COOLING SYSTEM MAKHOSTIA SDN BHD. KLIA DEFINITION OF DISTRICT COOLING SYSTEM A system for distributing heat generated in a centralized location for residential and commercial heating requirements. The heat is often obtained from a cogeneration plant, although dedicated facilities called heat-only boiler stations are also used. A district heating plant can provide higher efficiencies and better pollution control than localized boilers.

DEFINITION OF COGENERATION MAKHOSTIA SDN BHD. KLIA DEFINITION OF COGENERATION Is a process that converts a fuel into both thermal and electrical energy. The thermal energy may be in the form of steam, hot water, or hot air, or any combination of the three.

GDC/COGEN PLANT DESIGN OBJECTIVES MAKHOSTIA SDN BHD. KLIA GDC/COGEN PLANT DESIGN OBJECTIVES Reduce peak load demand of electricity in the country. Improve energy efficiency using natural gas in the country. Reliable chilled water supply. Adaptation of proven cogen plant technology for a long-term operational reliability. Adaptation of environmental friendly system thru the usage of non-CFC refrigerant for chillers and DeNox system for GTGs.

ADVANTAGES OF COGENERATION MAKHOSTIA SDN BHD. KLIA ADVANTAGES OF COGENERATION Savings in Capital Investment to Building Owners Save on cost for chillers and cooling towers Minimise number of spare equipment Savings in operating cost to Building Owners Save on operating and maintenance cost, through reduced electricity and manpower costs Optimisation of building space by building owners Alternative use for plant space to generate more revenue, either rent or sell

ADVANTAGES OF COGENERATION MAKHOSTIA SDN BHD. KLIA ADVANTAGES OF COGENERATION Higher System Reliability Higher degree of reliable power and chilled water supply as two power supply sources are available; internal generation and back up from power grid. Enhanced building aesthetics Wider choice for building design, could enhance property value

ADVANTAGES OF COGENERATION MAKHOSTIA SDN BHD. KLIA ADVANTAGES OF COGENERATION Higher Energy Efficiency Cogeneration system efficiency of up to 70% against 50-60% for combine-cycle power plant. Environment-friendly Clean natural gas as fuel, thereby minimising SOx and NOx emission. Absorption chillers uses non-CFC based refrigerant.

ADVANTAGES OF COGENERATION MAKHOSTIA SDN BHD. KLIA ADVANTAGES OF COGENERATION TOTAL USABLE ENERGY : 70 % FUEL ENERGY INPUT : 100% ELECTRICAL ENERGY : 30 % USABLE HEAT : 40 % WASTE HEAT : 30 %
