The push toward enhanced grid resilience, reliability, and remote diagnostics also fuels preference for GIS over traditional AIS in 61% of retrofit projects.

RESTRAINT

"High upfront capital and technical complexity"

High acquisition and technical complexity limit GIS adoption in around 37% of utilities, particularly in emerging economies. GIS capital intensity can be 3× that of air-insulated substations for the same ratings, deterring smaller utilities. Skilled labor is required for assembly, testing, and maintenance, with over 45% of grid operators citing technician training as a major hurdle. In retrofit scenarios, adapting existing infrastructure to GIS can require up to 22 weeks of additional civil and electrical rework, further delaying timelines.

OPPORTUNITY

"Modular GIS and greening initiatives"

Modular GIS packages represent 29% of new deployments, indicating opportunity for reduced installation time (by up to 50%), space savings (footprint reduced 80% compared to AIS), and minimized on-site labor.
