Construction The services include constructing procedures and activities for:

• Energy supply systems for remote applications such as: telecommunication systems, village energy supply, home industries, agriculture processing center, drinking water supply, and public health facilities utilizing locally available energy sources such as solar micro-hydro, wind, biomass, and combination of them (hybrid).
• Technical systems utilizing renewable energy sources for communication sectors (i.e. photovoltaic, micro-hydro), such as: base transceiver station (BTS), repeater station, radio communication (e.g. sea navigation, railway crossing, radio beacon, and highway information system), cathodic protection, traffic signaling (e.g. light house, buoy, barrier flasher).
• Decentralized power supply systems and rural electrification, such as: stand-alone photovoltaic, floating PV for coastal areas, micro-hydro power, biomass, wind energy converter, and hybrid power systems.
• Mechanical and electrical for private houses, real estates, commercial buildings, and industries.
• Lift, escalator, passenger conveyor, and other within-a-building transportation types.
• Biomass gasification to replace the use of fossil-fueled energy.
