Implementation of Solar Rooftop Photovoltaic Systems
on PEA Buildings Nationwide (2018 - 2024)

The Provincial Electricity Authority (PEA) has implemented the installation of solar rooftop photovoltaic (PV) systems on office buildings and substations across the country. The installed capacity for each site ranges from 5 to 50 kilowatts-peak (kWp), with a total of 815 installations nationwide, amounting to an aggregate installed capacity of approximately 10.83 megawatts-peak (MWp).

The primary objective of this initiative is to generate electricity for self-consumption within PEA’s facilities, thereby reducing the buildings' electricity expenditures and enhancing overall energy efficiency. This effort reflects PEA’s commitment to sustainable energy practices and aligns with Thailand’s broader energy transition and carbon reduction goals.

The system is capable of generating no less than 15.81 million kilowatt-hours (kWh) of electricity per year

This is equivalent to a reduction of no less than 7,900 tonnes of carbon dioxide equivalent (tCO₂eq) per year

This results in an annual reduction in electricity expenses of no less than 71.07 million Thai Baht

Implementation of Solar Rooftop Photovoltaic Systems
on PEA Buildings Nationwide (2025)

The Provincial Electricity Authority (PEA) is currently expanding its initiative to install solar rooftop photovoltaic systems on PEA buildings nationwide, totaling 259 locations.

The system is capable of generating no less than 6 million kilowatt-hours (kWh) of electricity per year

This is equivalent to a reduction of no less than 3,000 tonnes of carbon dioxide equivalent (tCO₂eq) per year

This results in an annual reduction in electricity expenses of no less than 27 million Thai Baht

STATUS: Currently, in 2025, PEA is currently expanding its initiative to install solar rooftop photovoltaic systems on PEA buildings nationwide.
