Gas-Insulated Substation Market Size

Gas-Insulated Substation Market size was valued at USD 33.85 billion in 2024 and is likely to cross USD 112.78 billion by 2037, registering more than 9.7% CAGR during the forecast period i.e., between 2025-2037. In the year 2025, the industry size of gas-insulated substation is assessed at USD 36.48 billion. The growth of this market can be attributed to the growing demand for compact, low-maintenance power systems by the end of 2035. Gas-insulated substations are generally more reliable and efficient than air-insulated substations. Increasing per-hectare land values is also expected to provide lucrative growth opportunities for the market as the gas-insulated substation consumes space as compared to its equivalents. This substation consumes up to 90% less space than a typical power plant this factor is expected to drive the growth of this market in the forecast period. The main advantage of GIS is that it takes only 10% area of normal substations.

Moreover, rise in the renewable power generation, increasing funds for distribution and transmission infrastructure, the growth in energy demand and restriction of space availability in densely populated urban areas, and also government programs towards electricity accessibility are a few significant factors anticipated to propel the growth of market in the forecast period. The growing investment by the government has also led to the increasing construction of gas-insulated substations globally. ABB was awarded a contract for over USD 100 million in 2021 to provide a substation for the UK's transmission network to incorporate electricity from the Hinkley Point C nuclear power facility. Gas-insulated switchgear will be used in the substation to ensure excellent reliability and efficiency.
