TSE’s vision statement is to become a world-class regional leader in providing renewable energy through reliable technologies to serve both commercial and social societies. Its mission statement is to establish a solid footprint in Thailand in the solar power industry and expand into other renewable energies as well as developing an international solar power business focusing in Asia and the Oceania regions.

Out of the many company milestones in its ten years of existence, several stand out. One of them is how TSE started relatively small to become a company with 11 solar plants, totaling 85 MW, from 2011 to 2014. TSE also succeeded in securing a loan to finance a USD200 million solar farm project from Bangkok Bank Public Company Limited, a leading financial institution in Thailand. Besides that, TSE succeeded in bringing in a company like Global Power Synergy (GPSC) as a strategic partner of the company in 2013. GPSC is the electricity and utility flagship of the PTT Public Company Limited, a Thai state-owned oil and gas company listed on the Stock Exchange of Thailand (SET). TSE itself was listed on the SET in late 2014 with a market capitalisation of over USD200 million. Lastly, in Japan, the company has secured over 200 MW solar energy in 2017 only after four years of entering into the Japan market.
