Global Gas Insulated Transformer Market Growth

A gas-insulated transformer, also known as gas-insulated switchgear, utilises a gas, typically sulphur hexachloride (SF6), as an insulation medium to protect the components of the transformer. Its components are sealed in a metal enclosure, which is filled with insulation gas to reduce any environmental hazard and risk.

The gas insulated transformer market dynamics and trends are influenced by the increasing need for compact transformers in densely populated urban areas. Additionally, gas-insulated transformers are ideal for installation in challenging environments, such as mountainous, underground, or extreme weather areas, due to their resilience to harsh conditions.

Africa’s renewable energy landscape also expanded, with total capacity rising from 56,123 MW to 58,796 MW, marking a 4.8% increase. Egypt maintained its leadership with a slight rise to 6,322 MW from 6,258 MW, while Ethiopia demonstrated significant growth with a 17.4% increase, reaching 5,589 MW from 4,759 MW, driven largely by hydropower projects. Angola and Kenya continued to expand their capacities, with increases to 4,066 MW and 2,649 MW, respectively. Notably, smaller nations like Benin, and Burkina Faso also made significant progress, with Benin jumping from 3 MW to 28 MW, and Burkina Faso’s capacity rose to 122 MW from 92 MW. Morocco’s capacity rose to 3,725 MW up from 3,638 MW. In contrast, some countries like Cameroon and Djibouti showed stable capacities at 827 MW and 20 MW indicating a potential focus on maintaining existing infrastructure. This increase in renewable energy capacity bolsters the growth of gas insulated transformer industry revenue, as gas-insulated transformers are preferred in renewable energy projects due to their compact design and high efficiency.

As per BP Energy, in 2019, electricity generation in Austria rose to 74.2 terawatt-hours (TWh) in 2019, reflecting a slight increase from 68.6 TWh in 2018. Belgium also showed an increase, generating 93.7 TWh in 2019, up from 75.1 TWh in 2018. Italy maintained its substantial role in Europe's electricity production, generating 293.9 TWh in 2019, up slightly from 289.7 TWh in 2018. The rise in electricity generation across Europe boosts the demand for reliable and efficient gas-insulated transformers, driving the gas insulated transformer industry revenue. This supports market growth as countries aim to upgrade power infrastructure and address rising energy needs.

Gas-insulated transformers (GITs) offer a smaller footprint compared to conventional transformers, making them ideal for space-constrained environments.

They are highly reliable with minimal maintenance needs due to their sealed construction, which protects against environmental factors.

The initial cost of GITs is higher than traditional transformers, which can be a barrier to adoption.

• Their advanced technology and construction can lead to complex installation and servicing requirements.

GITs may offer less flexibility in terms of customization and modifications compared to conventional transformers.

Increasing urbanisation and space constraints create a demand for compact and efficient GIT solutions.

• The expansion of renewable energy sources necessitates reliable and space-efficient transformer solutions like GITs.
• Ongoing advancements in gas insulation technology could enhance performance and reduce costs, driving the gas insulated transformer industry growth.

Economic downturns can impact investment in infrastructure projects, affecting GIT demand.

• Stringent regulations and standards related to gas handling and safety may pose challenges for manufacturers.
• Intense competition from alternative transformer technologies and manufacturers may impact gas insulated transformer market opportunities.
