What Power solution Technologies does

Power Solution Technologies Public Company Limited (PSTC) is a Thai publicly-listed energy infrastructure company originally founded in 2001 and listed on the Stock Exchange of Thailand (SET) under ticker PSTC. The company operates four integrated business segments: (1) Power Supply Solutions covering backup power systems, environmental monitoring, and energy-saving systems for industrial and commercial facilities; (2) Renewable Power Generation including solar (rooftop, farm, and floating installations), biomass, and biogas power plants with power purchase agreements (PPAs); (3) Petroleum Product Distribution through its 100%-owned BIGGAS subsidiary covering LPG, NGV, and LNG (LNG distribution authorized by PTT); and (4) Oil Pipeline Transportation via its TPN subsidiary operating a 342 km pipeline from Saraburi to Khon Kaen in Northeast Thailand.

PSTC serves a primarily B2B customer base spanning government agencies (Ministry of Energy), state enterprises (PEA, EGAT, PTT), industrial and manufacturing facilities, agricultural cooperatives, and rural telecommunications infrastructure under the USO program. The company demonstrated 70 MW of renewable PPAs with a published target of 200 MW by 2025 and projected annual oil throughput of 3,500 million liters per year through the Northeast pipeline. Revenue is generated through negotiated EPC contracts, long-term PPA tariffs, petroleum distribution margins, and pipeline transportation fees.

Major strategic actions include the 2019 acquisition of the remaining 49% of BIGGAS for 4,260 million THB, the EIA approval and CPP-contracted construction of the 9,200 million THB Northeast oil pipeline, and the planned upgrade from mai to SET main board. Ownership is concentrated among founders (~35%) and BGTH former shareholders (~35%), with institutional co-investors EGCO (44.6% in TPN) and GL Energy Solutions (7-8% in TPN) backing the pipeline venture.
