Thailand Power System Flexibility Study
With the growing share of renewable energy and emerging technologies, establishing
and maintaining adequate flexibility is an important part of Thailand’s power system
development and modernisation, and the country’s clean energy transition. Power system
flexibility is crucial for ensuring security of supply. Thailand’s power sector has
two main avenues to enhance its flexibility. One is to enhance the technical flexibility
of the system. The other is to change or reform commercial and contractual structures.
This study examines flexibility from both the technical and contractual angle, and
their interactions, using the current context of Thailand’s power system. For technical
flexibility, the report analyses the flexibility requirements and assesses the value
of technical flexibility options, including flexible power plants, pumped storage
hydro and battery energy storage systems. For contractual flexibility, the report
analyses the impacts of existing power purchase agreement and fuel supply contract
structures on system flexibility. This report provides recommendations for the system
to be able to use the full range of flexibility options in the most cost-effective
and secure way.
