這是有史以​​來最便宜的清潔電力，沒有之一。智利剛剛啟動了塞羅多米納多二號太陽能發電廠。Chile offers some of the world's cheapest solar energy, with recent 2026 reports indicating prices as low as 1.9 US cents per kilowatt-hour ($19/MWh) in the Atacama Desert. High solar irradiance and 24-hour molten salt storage capacity allow for consistent, low-cost baseload power.

這是有史以​​來最便宜的清潔電力，沒有之一。

智利剛剛啟動了塞羅多米納多二號太陽能發電廠。這座3500兆瓦的巨型太陽能發電廠坐落在阿塔卡馬沙漠高原2400公尺的高處。在如此高海拔地區，大氣稀薄，陽光幾乎不會散射。濕度接近零，因此太陽能電池板無需清潔。它將傳統的光伏電池板與巨大的熔鹽熱能核心結合，確保電網24小時不間斷供電。

智利現在生產的廉價能源如此之多，以至於他們將剩餘電力直接輸送到阿根廷、秘魯和玻利維亞。每度數1.9美分的價格，使得天然氣徹底過時。

Key Aspects of Chilean Solar Power

• Record Low Prices: Chile has consistently set global records for low-cost solar, dropping below $0.029 per kWh as early as 2019.
• Atacama Advantage: The Atacama Desert has the highest solar irradiation in the world, allowing for massive production efficiency.
• Major Projects: The 3,500-megawatt Cerro Dominador project in the Atacama serves as a key example of high-capacity storage, combining photovoltaics with thermal storage.
• Market Growth: By 2023, solar power accounted for 9.4% of Chile's total primary energy production, with solar generating 20% of the country's electricity.
• Export Potential: Due to high production and low costs, Chile is positioned as a key exporter of clean energy to neighboring countries like Argentina, Peru, and Bolivia. [1, 2, 3]

Factors Driving Low Costs

• High Irradiance & Elevation: The combination of high altitude and low cloud cover in the Atacama maximizes photovoltaic output.
• Auction Systems: Government-led competitive bidding for energy contracts has driven dramatic cost reductions, removing the need for subsidies.
• Storage Integration: The use of batteries in solar projects has become standard for balancing supply, strengthening the competitiveness of the sector. [1, 2, 3, 4]
