EGAT revealed the progression of developing Thap Sakae District to be research and development center of renewable energy. The 5 MW solar power project and the other two research projects comprising the 250 kilowatt horizontal axis wind turbine project and the 500 kilowatt biogas power plant project using Napier grass as fuel are developed.

The 631.48 million baht solar project, which is now under installation process, has the commercial operation date in May 2015. It was approved by the Cabinet in 2013 as one of EGAT's renewable projects with an aim to reduce the use of fossil fuel and the CO2 emission that has an impact on the environment. The solar plant was designed to use 4 types of solar cells that are 1 MW Crystalline Silicon solar cell equipped with solar weight tracking system, 2 MW Amorphous Silicon, 1 MW Micro Crystalline Amorphous Silicon, and 1 MW Copper Indium Di-Selenide in order to compare their generation efficiency. Four companies namely Hydrochina International Engineering Co., Ltd., Ying Energy (Beijing) Co., Ltd., Hedei Electric Power Design & Research Institute, and Watanasuk Engineering Co., Ltd. were selected to implement the solar power plant project.
