Solar Power Undercuts Coal as Renewable Energy Costs Hit Record Low Across Asia Pacific

The cost of generating electricity from renewable sources has plummeted to an all-time low across the Asia Pacific region, marking a pivotal shift in the global energy landscape. According to Wood Mackenzie’s latest analysis, renewable energy has become increasingly competitive with conventional coal power, driven by a dramatic reduction in capital costs.

The levelized cost of electricity (LCOE) for renewables declined significantly in 2023, making clean energy sources more economically attractive than ever before. Consequently, renewable energy costs now sit 13% cheaper than conventional coal power. Furthermore, projections indicate this gap will widen substantially, with renewables expected to be 32% cheaper than coal by 2030.

Solar Emerges as the Region’s Most Affordable Power Source

Utility-scale solar photovoltaic (PV) power has emerged as the clear winner in the race for cost-competitive energy. In 2023, utility PV became the cheapest power source in 11 out of 15 countries across the Asia Pacific region. This remarkable achievement follows the end of two years of supply chain disruptions and inflation that had temporarily stalled the sector’s progress.

“Utility PV solar has emerged in 2023 as the cheapest power source in the region, while onshore wind is expected to become cheaper than coal after 2025,” stated Alex Whitworth, Vice President and Head of Asia Pacific Power Research at Wood Mackenzie.

Solar PV power costs experienced a 23% decline in 2023, driven primarily by a 29% drop in capital costs. This steep reduction has fundamentally altered the economic equation for power generation across the region. Moreover, the trajectory suggests continued cost reductions ahead, with new-build solar project costs projected to fall another 20% by 2030.

China Leads the Renewable Cost Revolution

China has established itself as the undisputed leader in lowering renewable energy costs. The country’s utility PV, onshore wind, and offshore wind installations operate at costs 40-70% cheaper compared to other Asia Pacific markets. This massive cost advantage stems from China’s dominant manufacturing capacity and economies of scale.

Additionally, China’s competitive edge appears sustainable over the long term. The analysis indicates that China will maintain a 50% cost advantage for renewables extending out to 2050. As a result, the country is positioned to maintain its leadership in renewable energy deployments for decades to come.

The decline in solar technology costs during 2023-24 has created intense competitive pressure on traditional coal and gas power generation. Falling module prices and increasing oversupply from China continue to drive costs downward, fundamentally reshaping regional energy markets.

Wind Power Poised to Join the Cost Competition

While solar has captured headlines with its dramatic cost reductions, onshore wind power is not far behind. According to Wood Mackenzie’s projections, onshore wind is expected to become cheaper than coal after 2025. This milestone will further accelerate the transition away from fossil fuels across the region.

“Renewables firmed with battery storage is becoming competitive with gas power today but will struggle to compete with coal before 2030,” Whitworth added, highlighting the nuanced competitive dynamics at play.

However, the integration of battery storage with renewable sources presents both opportunities and challenges. While renewable energy paired with storage solutions is increasingly competitive with gas-fired power generation, competing directly with coal’s economics remains difficult in the near term.

Implications for Regional Energy Markets

Sooraj Narayan, Senior Research Analyst for APAC Power & Renewables at Wood Mackenzie, emphasized the transformative nature of these developments. The convergence of falling costs, technological improvements, and manufacturing scale has created unprecedented momentum for renewable energy adoption across the Asia Pacific.

The economic case for new coal power plants has weakened considerably as renewable costs continue their downward trajectory. In contrast, utility-scale solar projects now offer superior economics in the majority of regional markets. This shift has profound implications for future infrastructure investments and energy policy decisions across the region.

Furthermore, the continued decline in capital costs for renewable power projects enhances their attractiveness to investors and utilities. The 13% cost advantage that renewables currently hold over coal represents merely the beginning of a widening economic gap that will reshape energy markets throughout the coming decade.

Looking Ahead to 2030 and Beyond

The trajectory for renewable energy costs appears firmly established. With solar project costs expected to drop an additional 20% by the end of this decade, the economic advantages of clean energy will only strengthen. Meanwhile, onshore wind’s anticipated cost parity with coal after 2025 will create additional competitive pressure on fossil fuel generation.

The structural advantages that China has built in renewable energy manufacturing and deployment suggest the country will continue shaping regional and global energy markets. Its ability to produce renewable energy technology at significantly lower costs than competitors creates powerful economic incentives for continued expansion.

As renewable energy costs in the Asia Pacific region continue declining, the economic rationale for transitioning away from fossil fuels strengthens across multiple dimensions. The combination of environmental benefits, energy security considerations, and superior economics positions renewable energy as the dominant power source for the region’s future. Consequently, the energy landscape across Asia Pacific is undergoing a fundamental transformation that will accelerate throughout the remainder of this decade.
