Cambodia’s Utility-Scale Solar Surpasses Planned Targets for 2030 and 2035

Why It Matters

The rapid utility‑scale rollout accelerates Cambodia’s 70‑80% renewable‑energy goal and lowers reliance on fossil fuels, but persistent rooftop barriers risk underutilizing low‑cost clean power for industrial consumers.

Key Takeaways

• Installed utility‑scale solar hits 1.5 GW, exceeding 2030 target
• Projected 2026 additions could push capacity near 2 GW
• Zero import tax cuts solar project costs by up to 30%
• Rooftop PV limited by 30 MW quota and high compensation tariffs

Pulse Analysis

Cambodia’s solar surge reflects a broader Southeast Asian shift toward utility‑scale renewables. By the end of 2026, the nation is expected to host close to 2 GW of solar, driven largely by large‑scale projects such as the 930 MW Chheu Tom complex and a steady flow of Chinese panel imports. The government’s decision to eliminate the 15% import duty on solar and storage equipment, effective April 1, is projected to reduce overall project expenditures by roughly 7.4%, making new builds financially attractive and positioning Cambodia ahead of its Power Development Master Plan benchmarks for 2030 and 2035.

Despite the utility‑scale momentum, distributed solar remains stunted. A statutory rooftop quota of just 30 MW, coupled with a compensation tariff that far exceeds the actual grid impact cost, extends payback periods for commercial and industrial users by nearly two years. Grid‑stability concerns from state‑owned Electricité du Cambodge and the utility’s fragile balance sheet have entrenched these restrictions, limiting manufacturers’ access to cheaper, low‑carbon electricity even as the country pursues a 70‑80% renewable share by 2030.

Looking forward, the looming LNG‑to‑power plant slated for 2027 could raise electricity tariffs and increase carbon intensity, potentially eroding the gains from solar expansion. Removing rooftop barriers and allowing the utility to purchase surplus rooftop generation would diversify supply, lower costs for high‑tariff consumers, and reinforce Cambodia’s commitment to the Fossil Fuel Treaty Initiative. The country’s experience underscores the importance of aligning policy, grid management, and financing to fully harness renewable potential in emerging markets.
