OHL / UGL
Overhead transmission lines (OHL) have been the preferred system for power transmission due to cost, flexibility, and ability to transmit bulk power over long distances. Underground transmission lines (UGL) have been mainly used in urban areas and to cross bodies of water.
HVDC (High Voltage Direct Current) / MVDC (Medium Voltage Direct Current) can expand power grid transmission networks, making them more stable. HVDC / MVDC is more environmentally friendly than "Alternating Current" (AC), providing more energy per square meter, more efficiently than AC systems, as well as lower losses and less space requirements.
;)
SUBSTATION
A substation is part of an electrical generation, transmission, and distribution system. Substations transform voltage from high to low, or the reverse.
We are addressing the need for infrastructure networks to support the changing energy landscape and growth in the renewable and utility energy sectors. We provide high voltage transmission (500/275/132kV) & medium-low voltage distribution (33/11kV/.415kV) of electricity supply to connect people and businesses to the energy they need.
;)
protection, control & automation
The Protection, Control & Automation of a power supply system is the engineering entity that specializes in developing solutions for control and protection for electrical substations, datacenter, distribution networks, microgrids, smart grids and renewable generations.
We provide customized (i.e. SCADA/DA/RTU/FTU) solutions to automate grid operations and improve security & reliability of electricity supply.
;)

Rooftop Solar PV for Residential, Commercial & Industrial Buildings
For a residential building, homeowners could benefit from generating their own electricity with solar PV system and save up to 90% of the electricity bill for 25 years. With the Net Energy Metering (NEM) program, excess solar electricity could be exported and stored in the grid, thereby providing an attractive return on investment.
For commercial & industrial buildings; electricity bills are one of the significant utility expenses and the unpredictable trend of rising electricity costs is a financial threat to any organization. Implementing solar energy will effectively reduce imported electricity consumption and potentially reduce maximum demand charges while minimizing carbon footprint. Companies and organizations who qualify for green investment tax allowance could enjoy corporate tax incentives from the government.
;)
Building Integrated Solar PV Structures
Building-integrated photovoltaics (BIPV) are photovoltaic materials that are used to replace conventional building materials in parts of commercial and industrial buildings such as the roof, skylights or facades.
Solar BIPV carpark solutions is an ideal example for outdoor parking structures, as it is an increasingly popular way to lower electricity costs while providing a comforting environment to park your car and display commitment towards environmental sustainability.
;)
Utility Scale / Large Scale Solar (LSS)
Large scale solar (LSS) also known as a solar farm / plant, which is essentially a large-scale application of solar photovoltaic (PV) systems in a contained area so that electricity (ranging from thousands of kilowatts to thousands of megawatts) can be generated for use. The overreaching benefit for LSS farms is that it ultimately increases the clean energy supply and consumption of renewable energy (RE).
Hasilwan have developed & invested in more than 100 MWp of large scale solar projects under government RE initiatives such as the LSS, Net Energy Metering (NEM) & self consumption (SELCO) programs.
;)
Off-gird Hybrid Solutions + Energy Storage Systems
Being off-grid refers to not being connected to a power grid, especially in a remote or rural area. In order to provide the same energy security and reliability (similar to a grid connected system), a customized hybrid power supply & microgrid system is required to meet a specific electrical demand pattern.
To build a more sustainable and green energy ecosystem; an energy storage medium (i.e. battery, hydrogen, etc.) is essential for storing energy produced by intermittent sources of renewable energy (i.e. solar PV, wind etc.) for primary consumption & secondary storage utilization.
Energy Efficiency
Energy Efficiency (EE) is the process of using less energy to support the same process of providing products and services. Improvements in EE are generally achieved through Energy Saving Measures (ESM) by adopting a more efficient technology, process or application to reduce energy losses & inefficiencies. For commercial & industrial clients, Hasilwan offers various integrated EE solutions such as Energy Audit, government EE grant / incentive application, Energy Monitoring & Energy Saving Measures (ESM) - see ESM options below.
