South America Renewable Energy Market Trends and Insights

Renewable-Energy Auction Programs Accelerating Project Pipeline

Competitive tenders replaced feed-in tariffs after 2023. Brazil, Chile, and Colombia jointly awarded 8.5 GW in 2024-2025, and penalty clauses now force bidders to secure equipment and grid permits before signing, which cuts speculation and speeds build schedules. Brazil’s 2024 reserve auction cleared 3.1 GW at USD 28 per MWh, a record low that showed solar-plus-storage can compete with gas peakers. Chile’s 2025 2.5 GW call mandates four-hour batteries, ensuring a firm evening supply. Colombia’s 2.2 GW award in 2024 reopened its stalled market, while Argentina’s provinces tendered 800 MW of wind to bypass federal budget limits. These rules give investors confidence that contracted assets will connect on time and earn revenue from day one.

Declining LCOE for Solar PV and Onshore Wind

Utility-scale solar averaged USD 29 per MWh in 2024 as bifacial modules and single-axis trackers boosted yields by up to 20%. Onshore wind fell to USD 35 per MWh, helped by 120-meter hub heights that catch steadier flows in Brazil’s northeast. Chile’s Atacama solar parks signed sub-USD 20 PPAs in 2024, prompting early retirement of 1.2 GW of coal. Wind farms in Bahia logged more than 50% capacity factors in 2024, shrinking payback periods to under seven years. Cost parity against fossil assets has ended the need for subsidies, letting corporate buyers sign direct PPAs at tariffs 10-15% below retail rates.

Transmission Bottlenecks and Interconnection Delays

Brazil’s Bahia queue reached 5.4 GW in late 2024, stretching average wait times to 18 months as new substations lag project completion. Chile’s Atacama backlog stranded 3 GW and caused 1.8 TWh of curtailment in 2024. Patagonia wind projects face a 24-month delay because high-voltage links to Buenos Aires remain unfunded. Long queues raise development costs 10-15% and erode tariff margins, pushing sponsors to demand grid-access guarantees before closing debt.

Other drivers and restraints analyzed in the detailed report include:

• Green-Hydrogen Export Ambitions Driving Utility-Scale Additions
• Mining-Sector Corporate PPAs for Off-Grid Decarbonization
• Local-Content Rules Increasing OEM Capex

Segment Analysis

Hydropower held 52.98% of 2025 capacity, yet environmental permitting and variable rainfall slow new builds. Solar will grow at an 18.30% CAGR, the fastest of any technology, propelled by sub-USD 30 per MWh economics and modular designs that skirt transmission bottlenecks. Wind adds about 4.5 GW annually, boosted by 50% capacity factors in Brazil’s northeast. Bioenergy contributes 12 GW through bagasse-fired cogeneration, anchored by Brazil’s RenovaBio targets. Emerging niches include pumped-storage hydropower such as Brazil’s 401 MW Sinop project, which delivers eight-hour discharge capability. Offshore wind development is taking shape with a 16 GW Brazilian pipeline aiming for first turbines in 2027.

Solar’s rapid buildout is shifting the power mix, yet higher variable output requires storage for evening peaks. Concentrated solar power remains marginal beyond Chile’s 110 MW Cerro Dominador plant due to USD 6,000-per-kW costs. Geothermal holds 48 MW at Cerro Pabellón, though Enel is exploring another 200 MW in the Andes. Ocean energy is still confined to pilot projects with capital costs above USD 10,000 per kW. The South America renewable energy market size allocated to solar and wind will therefore expand faster than hydro until 2031, provided that storage and grid upgrades keep pace.
