What is a primary advantage of underground substations?

The primary advantage of underground substations is that they occupy less surface land. This benefit is particularly significant in urban environments where land is limited and expensive. By placing substations underground, the surface area can be utilized for other purposes, such as parks, buildings, or roads, thereby maximizing the use of available space.

In addition, underground substations can help reduce visual clutter and noise pollution, as they are not seen or heard above ground. While aesthetics may be a factor in evaluating underground installations, the most substantial and practical advantage revolves around land use efficiency.

Other considerations, such as maintenance and equipment requirements, may be influenced by the underground nature of the installation, but the most direct and impactful benefit is the reduced footprint on the surface, making it a crucial factor in the planning and development of substations.
