South America Medium Voltage Switchgear Market Trends and Insights

Surging Grid-Reinforcement Programs in Brazil’s Northeast

Brazil’s northeast corridor is executing the largest retrofit wave in two decades. ANEEL cleared 687 reinforcement works worth BRL 1.05 billion in January 2026, followed by BRL 572.6 million in March for 100 additional upgrades. Projects focus on 230 kV and 138 kV substations that need compact GIS bays to squeeze into energized yards, minimizing outages. The upcoming BRL 5.8 billion auction adds 4,800 MVA and 888 km of new lines, extending a multi-year tailwind for the South America medium voltage switchgear market.

Accelerating Renewables-Driven Sub-Transmission Projects

Renewable curtailment above 10% has pushed Chile and Brazil to commission 220 kV and 132 kV collector systems. Chile’s 1,346 km Kimal-Lo Aguirre HVDC link broke ground in 2025, employing 7,000 workers and integrating 2.5 GW of wind with 1.3 GW under development. Colombia’s UPME tenders for Corzo and Nueva Lorica substations include 25-year concessions with commissioning slated for 2027-2031. Sub-transmission collectors demand 40-50 kA-rated switchgear with IEC 61850 compliance, driving procurement of digital GIS in the South America medium voltage switchgear market.

Currency Volatility Inflating Imported GIS Costs

Brazil’s 7.2%-20% import duties and a weak real widened GIS landing costs by up to 25%, while Argentina’s peso slide forced utilities toward lower-cost AIS retrofits. Domestic makers quoting in local currency gain share, altering price points in the South America medium voltage switchgear market.

Other drivers and restraints analyzed in the detailed report include:

• Utility Digital-Substation Modernization Mandates
• Electrification of Mining Operations in the Andean Belt
• Project Delays from Political Regime Changes

Segment Analysis

Gas-insulated switchgear will outpace the South America medium voltage switchgear market average at a 7.2% CAGR, yet AIS retains price leadership especially for 33 kV mining feeders. Siemens’ ARS 75 billion clean-air GIS in Córdoba sets a regional benchmark, halving footprint and eliminating greenhouse-gas insulation. Chile’s USD 79.6 million BESS-linked substations further confirm GIS as the urban default. Lifecycle savings, rising land prices, and environmental pressure ensure that GIS penetration will keep climbing within the South America medium voltage switchgear market.

AIS remains dominant in cost-sensitive applications with 58.7% 2025 share. In rural Brazil, greenfield 138 kV yards cost 30-40% less with AIS panels and allow quick spares interchange. The South America medium voltage switchgear market size for AIS will still grow in absolute terms, but its share will erode as regulators tighten SF₆ caps and urban projects migrate to compact bays.

DC switchgear’s 7.7% CAGR through 2031 reflects mounting solar output, BESS coupling, and the regional roll-out of CCS2 fast chargers. Brazil’s projected 600,000 EVs in 2026 require clustered chargers tied to MV feeders, spurring orders for bidirectional protection panels. FPSO electrification projects also specify DC fault-limiters to secure offshore grids.

AC switchgear remains ubiquitous above 138 kV and in industrial motors. With 85.1% 2025 share, incremental growth follows GDP and utility reinforcement plans. Hybrid yards combining AC main transformers and DC battery strings will emerge, creating cross-over opportunities in the South America medium voltage switchgear market.
