Thailand is on the brink of a transformative shift in its energy landscape, projected to save an impressive $1.8 billion in power generation costs from 2026 to 2037. This could be achieved by exceeding the current targets of its revised Power Development Plan (RPDP) with significant upgrades in solar and battery storage capacity.
In an enlightening analysis, Ember has suggested that by boosting solar capacity by 89% and battery storage by 60% beyond the existing RPDP targets, Thailand can realize substantial savings, enhance energy security, and attract vital investments. Currently, the RPDP aims for 36 gigawatts (GW) of solar and 10.5 GW of battery storage by 2037.
Ember’s proposal includes an additional 32 GW of solar capacity and 6 GW, or 15 gigawatt-hours, of battery storage over the plan’s existing goals, coupled with a reduction of 2 GW in new gas-fired capacity. This proactive approach not only aims to prevent the construction of excessive fossil fuel infrastructure but also slashes natural gas consumption by 11% and avoids the use of 2.4 million tonnes of coal.
The analysis notes that while the total fixed expenditures for this cost-optimal pathway would reach $168 billion by 2037—higher than the RPDP’s estimate of $153 billion—the advantages of embracing solar and battery technology could lead to nearly $16 billion in avoided fossil fuel expenditure. As a result, net savings in power generation costs for Thailand would amount to $1.8 billion, including $0.8 billion saved in variable operation and maintenance costs.
Ember’s findings advocate for a robust deployment of solar and battery technologies as the most cost-effective strategy, recognizing the limited wind energy potential in Thailand. Yet, the interplay between wind and solar should not be overlooked, given the natural ebb and flow of solar generation.
“The energy transition of Thailand towards home-grown renewables could lower energy costs, cut emissions, and strengthen energy security by mitigating dependence on fossil fuel imports,” remarked Lam Pham, the report’s author and energy analyst for Asia at Ember. In short, it looks like Thailand isn’t just aiming for energy independence; it’s gearing up to create its own renewable energy empire.
What role will solar and battery storage play in Thailand’s energy future?
Solar and battery storage are set to significantly reduce reliance on fossil fuels, enhance energy security, and lead to considerable cost savings in power generation.
How much could Thailand save by exceeding its current energy targets?
By adding more solar and battery storage capacity, Thailand could save approximately $1.8 billion between 2026 and 2037.
What does the Ember report suggest about gas-fired power plants?
The report proposes reducing planned gas-fired capacity by 2 GW while increasing renewable capacity, indicating a strategic shift towards sustainability.
