Annual General Meeting of Shareholders of 2015 on 29 April 2015 at 10:00 a.m., at Thai Army Club, Makawan Room, Zone C

Thai Solar Energy Public Company Limited, or TSE, started its securities trading in MAI for the first time on Oct 30st, 2014, being confident on positive investors’ responses backed by the company’s business potentials after it saw significant demand at the subscription price of 3.90 Bath/share. Executives emphasized on strengthening TSE, aiming for another government-sponsored solar energy project. Bualuang Securities PCL., TSE’s financial advisor, suggested a bright future for energy sector, supported by Thai government’s plan to generate additional solar power production of 3,000 MW by 2021.

Dr. Cathleen Maleenont, President and Chief Executive Officer of Thai Solar Energy PCL (TSE), a Thai solar-based power producer that supplies electricity to the government following the policy of Energy Policy and Planning Office, Ministry of Energy to encourage production and consumption of renewable energy, and distributes electricity to Provincial Electricity Authority (PEA) and Metropolitan Electricity Authority (MEA) revealed that the TSE stock will begin trading in MAI for the first time on October 30th, 2014 using the symbol “TSE” after it completed IPO for its 450 million shares with the par value of 1 Bath/share and the subscription price of 3.90 Bath/share between October 21st-24th, 2014, having confidence that TSE share will be warmly welcomed by the investors.

TSE’s vision is to be the leader of renewable energy with emphasis on solar power plants using the right technology on the proper location to ensure high and sustainable returns. It also aims to expand into other types of renewable energy, such as wind power, biomass, biogas, and waste-to-energy, and expand its investment in solar power plants to other regional countries in the forms of solar farms and solar rooftops in order to put itself at the forefront of renewable energy business both in Thailand and Asia region.

Currently, TSE is a solar-based electricity producer and distributor with 25 projects in operation, totaling 98.5 MW. The projects are divided into 2 categories: solar thermal energy (STE) plants and photovoltaic (PV) plants. One STE plant, with its electricity production capacity and sale volume of 4.5 MW, has commercially operated. For PV plants, the company co-invested with Global Power Synergy Co., Ltd. (GSPC), a company specialized in electricity production in the PTT Group, to construct 10 PV projects with total capacity of 80 MW in Kanchanaburi province and Suphanburi province. All 10 projects have now commercially operated. Furthermore, TSE also co-developed 14 commercial rooftop PV solar projects with its business alliances, HomePro Group and The Mall Group. The projects, each producing 1 MW and totaling 14 MW of electricity generated, have started to commercially operate and are expected to reach CODs within this year. This results in the company being the biggest solar rooftop producer and distributor in Thailand.

“We are highly confident in the growth potentials of our company. Our capability to expand in solar power business following the government policy will place us at the top of renewable energy industry both in Thailand and Asia.”, stated Dr Cathleen.

The capital raised from IPO at around 1,755 MB will be used to expand TSE’s business both in Thailand and abroad, such as investment in solar power plants and other renewable energy plants and EPC business for solar power plants. Part of the funds will also be used to repay TSE’s existing long-term debts and to support the company’s working capital needs.

Mr. Pichet Sithi-Amnuai, President of Bualuang Securities PCL and TSE’s financial advisor and underwriter, stated that renewable energy business in Thailand is looking at a bright future supported by Thai government’s policy to encourage participation from private sector in the production of renewable energy. Thai government increased the production target of renewable energy in its Alternative Energy Development Plan 2012-2021 to 25% of total electricity generation, and recently gave approval to increase the production target of renewable energy in 2021 by 4,726 MW to 13,927 MW. This will benefit solar-based electricity sector, which currently has target production of 3,000 MW by 2021, as it is expected that the government may raise its solar electricity purchase from private producers.

TSE’s solid foundation in solar power business in Thailand and its plan to expand into Asia region clearly reflect its unmatched potential and unequivocal determination to seize the leading position in renewable energy business both in Thailand and Asia. This will secure investors’ trust and assurance towards the company’s business direction, performance and future growth.
