EGAT is finalising the new 20-year Power Development Plan (PDP). It appears that coal is being prioritised to ensure long-term power security and affordability. With the depleting piped gas reserves and the projected role of high cost LNG, increasing the share of gas in the fuel mix will directly translate into higher power tariffs. To maintain the tariffs at current levels in real terms, we forecast that the contribution of coal in the plant capacity mix should top 20% by 2025 and 30% by 2030.
