• f energy, as well as to develop and

support the production and use of alternative energy to enhance sustainable energy security.  Thus, current and ongoing government policies and actions shall comply with this Section.  Set up biomass quality and pricing standard and develop market  Initiate database of biomass producer  Study/develop technology to transform biomass feedstock for value added  Encourage firm contract for biomass power plant PPA  Recently, Ministry of Energy has informed that there could be adjustment to the PDP 2018 where renewable portion could increase even further.  A professor from Thailand’s leading institution has proposed an opinion

• f increasing the renewable portion

up to 40%.

Constitution of the Kingdom of Thailand, 20 years National Strategy, Country Reformation and Government Commitment to Support Renewable Energy

According to Constitution of the Kingdom of Thailand, Section 6 Number 5: Thailand will develop and support the production and usage of renewable energy for the security and sustainability of the future of Thai energy

• Government will develop

and support the creation of Bio-Circular Green

• Economy. Allowing

communities and farmers to partake in the creation

• f power and electricity.
• Develop a middle platform

for buying and selling of electricity (P2P).

• Decrease CO2 emission
• Solve PM 2.5 problem at

the source

• Support systematic,

hygienic, and proper management of Municipal Solid Waste (MSW).

• Develop and support the

growth of fuel crops in Thai agriculture.

• Develop contract farming

for fuel crops.  Increase in megawatts from Biomass and Biogas power plants.  ACE can sell left over capacity directly to user.  Biomass power plant is the solution to PM 2.5 problem by buying agricultural waste from farmers and therefore prevents the farmers from burning the waste in their fields.  ACE is a model and leader in the operation of MSW power plant in Thailand with the ability to process 80% moisture content waste as well as being the

• nly zero discharge MSW

power plant in Thailand.  Official support from governments mean more fuel in the market for ACE.

Biomass Powerplant MSW Powerplant Contribute to the Paris Agreement Decreasing Greenhouse Gas Emission. Future Potential To provide base-load to grid instead of conventional energy

• Saves government’s spending on putting down forest fires and farm fires
• Saves government’s spending on PM 2.5 related health problems such as respiratory

complications, masks distributions, water spraying in cities, etc.

• Prevents economic loss from the decrease in tourism due to PM 2.5 problem

Solves PM 2.5 problem at the root

• Additional income to farmers
• Stabilize income for farmers under market uncertainty → reduce empty subsidies that government

have to give out

• Stabilize electricity price preventing electricity price from increasing in the future
• Distribution of revenue to grassroots : Shift from expensive LNG imports to purchasing fuel from
