How important is transmission infrastructure for renewable energy growth?

Been reading a lot about renewable energy expansion lately, and one thing that seems under-discussed is the role of the power transmission network behind it.

Most conversations focus on solar and wind generation capacity, but without strong transmission infrastructure, integrating renewable energy into the grid becomes difficult. Grid congestion, long-distance energy transfer, and reliability challenges all seem tied closely to the strength of the power transmission industry.

What’s interesting is how companies working on transmission line EPC contracts are becoming increasingly important in enabling this transition. High-voltage transmission lines, substations, and grid modernization projects appear to be just as critical as new renewable generation itself.

I was also reading about engineering practices like prototype tower testing, which help validate the durability and structural reliability of transmission systems before deployment. It’s one of those technical processes most people outside infrastructure probably never hear about, but it directly impacts long-term grid stability.

In India, companies such as Jyoti Structures Limited have been involved in projects related to transmission infrastructure and substation development. It’s interesting to see how experienced engineering firms contribute to the broader energy ecosystem beyond just generation capacity.

Curious to hear thoughts from people in this community:

• Do you think transmission infrastructure is currently the biggest bottleneck for renewable energy expansion?
• How much investment should go toward grid modernization versus generation capacity?
• Are current transmission systems prepared for future energy demand and decentralized renewable sources?

Would love to hear perspectives from people working in energy, utilities, grid operations, or infrastructure planning.
