Smart Energy improves the power distribution system on the two substations through the Smart Grid which has begun by burying the cables underground to ensure stability, efficiency, and energy safety, as well as, helping to improve the scenery in the area. Additionally, it has begun to develop a solar energy power generation system and a plan to test the installation of an energy storage system in the Suanluang-Samyan area. The system will consist of two substation buildings, namely the Pathumwan and Samyan Station, thus ensuring that the area will have enough electrical power to meet the future growing demand.


  • SOLAR ENERGY power generation 10.3 MW

The renewable energy generation system was established with the objective to reduce environmental and social impacts that may arise from the original form of energy use especially the use of energy that contributes towards greenhouse gas emissions, which is one of the major causes of urban pollution. It also expected to reduce costs associated with local energy use in the long run.


Solar energy production is targeted to produce electricity through the installation of roof top solar panels (PV cells) on high-rise buildings (rooftop solar PVs) to create PV shading, that will help provide electricity generation and prevent heat from entering into the building. Besides the building, the installation of solar panels on roof structures are also intended to provide shade for the parking lot. Currently, the total installed area can produce up to 10.3 MW of electricity.

The district cooling plant is to consolidate the production of cooling to one single location and supply cool air to various buildings instead of installing separate air conditioning systems for each building. As a result, the construction cost and installation area are reduced, thus freeing up more usable space, in addition to, reducing the cost of resource management in terms of materials, equipment, and manpower. The Property Management Office has established an idea to allow the private sector to submit proposals to manage the district cooling system of the ​​Chulalongkorn University’s commercial area, which will supply cooling to development projects in the Suanluang-Samyan area with a production capacity of 18,000 RT in 2040, as part of the area energy management system (AEMS) measures.

Burying power and communication cables underground

The current development of the area that is being implemented amidst a state of rapid economic growth is resulting in the construction of an infrastructure system to support the economic expansion and the number of people in the area that tends to increase steadily. As a result, there is an increased need for various utilities, such as electricity and internet access. Most of the laying of electrical and communication cables at present are made on standing poles due to its easy installation and maintenance and lower production cost. However, it has also resulted in a cluttered and disorganized look overshadowing the beautiful city scenery, coupled with the tree branches that line the columns, which may cause additional damages. In addition to directly affecting the city’s landscape, the power poles also reduce the sizes of the sidewalks affecting pedestrians and people with disabilities. The Property Management Office, has, therefore, established a policy to bury electrical and communication cables underground to improve the city’s landscape into becoming more orderly, attractive, and safe, in addition to, enhancing the sidewalks to enable pedestrians and people with disabilities to can use by increasing the pavement size without the need to reduce the size of the road itself.

Siam Square’s new “cable-less” look which is to bury communication and power cables underground in the central commercial district to produce a more attractive landscape and ensure safety, is a collaboration with the Metropolitan Electricity Authority and related telecommunication partners.
