Seven opportunities in Thailand’s Solar Energy 2020

Walking on sunshine: Foreign investments in Thailand’s solar gold rush

Private energy investments: Thailand’s electricity generating sector is considered to be one of the most secure businesses in Thailand for private operators given the long-term power purchase agreement with the three state utilities EGAT (Electricity Generating Authority of Thailand), MEA (Metropolitan Electricity Authority and PEA (Provincial Electricity Authority). Renewable power plant businesses are traditionally promoted to reduce the heavy reliance on fossil fuel in Thailand, especially for gas, and to reduce the environmental impact. While the whole value chain from generation to transmission and distribution is and will remain largely a state-controlled industry, ongoing liberalization opens the door to new business opportunities for foreign companies, technologies, and concepts.

Solar milestones – from 3 GW to 3.4 GW at the end of 2019: At the end of 2019, Thailand looks back to nine tumultuous years of mostly favorable solar energy developments and a few failures. While 2010 saw the first significant installations of solar panels, the year 2017 marked the achievement of a significant milestone, a total of 3 GW of solar installations in the land of smile. This amounts to 50% of the 2036 target under the current 20-year roadmap (AEDP 2015). The total solar power capacity of roughly 3,500 MW can be predicted for the end of 2019.



An increase of renewable energy: Thailand’s >3 GW share exceeds 60% of total installed capacity in the ASEAN region, followed by the Philippines, Malaysia, and Singapore. To put this into perspective, Shady Germany installed already 40+ GW solar power. Thailand’s renewable energy quota (solar, wind, biomass) will be increased to 30% by 2030. Solar power from households will be the main source of power under the AEDP (Alternative Energy Development Plan).

Regulations, reports, roadmaps: Thailand is continuing its integrated energy blueprint, consisting of a gas plan, oil plan, the Energy Efficiency Plan (EEP), the Alternative Energy Development Plan (AEDP) and the Power Development Plan (PDP) with the Smart Grid Plan (SGP). The “IRENA” report, published on November 2017 by the International Renewable Energy Agency in cooperation with the Thai Ministry of Energy, showed new plans for expansions and further developments. According to the IRENA report, the share of renewable energy should increase from 12% in 2017 to 37%. Under such a new roadmap (REmap 2036), solar power alone would reach in 2036 a total capacity of 17 GW instead of the previously targeted 6 GW. Such a new target could be easily achieved taken into consideration the decreased solar panel costs, almost grid-parity conditions, and Thailands abundant solar energy resource potential. The average solar radiation in Thailand is 5 kWh/m2/year.

A brief history of Thailand’s solar energy

The overall development of Thailand’s legislation and governmental policy can be summarized at fast-forward speed as follows:

1993: Solar off-grid program for rural non-electrified areas for villages, schools, health care clinics and water pumping. 100% governmental support with regular maintenance, 30 MWp in total.

2007: Introducing of “Adder (Feed-in Premium)” policy for the VSPP and SPP for all renewable energy generation up to 90MWp. (Solar PV target: 500 MWp, Adder: 8 baht/kWh for 10 years)

2009: Under a 15-year plan (REDP) the solar target has been set to a capacity of 500 WM by 2022

2010: Solar PV target: 2,000 MWp. Since there were a huge amount of applications, the Adder decreased to 6.5 baht/kWh (or 18.6 US cent/kWh) for 10 years and an application moratorium had been introduced since June 2010.

2011: Under a 10-year plan (AEDP) the solar target has been set to a capacity of 2 GW till 2021. 2011 marks the policy change from the Adder scheme to the FIT scheme.

2013: Under a regulation of the Energy Regulation Commission, solar rooftop energy of up to 10 MW can be sold to the governmental utilities PEA and MEA. The regulation defines the criteria, procedures, and conditions of power purchase. The allowed total capacity of 200MW has commenced commercial operation. The solar PV target increased to 3,000 MWp. Solar farm: 2,000 MWp with Adder for 10 years. Solar Rooftop: 200 MWp with FiT 6-6.84 baht/kWh for 25 years. Solar for community 800 MWp with decreasing FiT for 25 years

2014: Solar PV target increased to 3,800 MWp. Solar farm 1,800 MWp with Adder for 10 years, solar farm 1,000MWp-applied before June 2010, changed from Adder for 10 years to FiT 5.66 baht/kWh for 25 years, solar rooftop 200 MWp with FiT 6-6.84 baht/kWh for 25 years and solar for community 800 MWp – changed to solar for governmental agencies and agricultural cooperatives – with FiT 5.66 baht/kWh for 25 years

2015: Phase 1 of the Agency and Agricultural Cooperatives Program (Agro-Solar). Under the AEDP 2015 plan, the target solar capacity has been set to 6 GW till 2035.

2016: Pilot project for Solar PV rooftop (for self-consumption) of 100 MWp and phase 2 of the solar for government agencies and agricultural cooperatives. 67 projects have won the right to sell a combined 281.32 megawatts (MW) of solar power to the national electricity grid for 25 years. Under the 2016 pilot project, the Energy Policy Management Committee divided in a resolution as of February 24, 2016, the 100 MW into 10 MWp for households (below 10 kWp) and 40 MWp for commercial use for EGAT and PEA each.

2017: Semi-firm and non-firm PPAs have been introduced which require hybrid renewable energy facilities. The new roadmap increases the 2036 target from 6 GW to 17 GW. The first “SPP hybrid firm” tender, launched in 2017, has a combined power-generating capacity of 300 MW with a FIT of THB 3.66 for the whole 20 year period. The ERC announced that they received applications from 85 firms with a combined capacity of 2,464 MW and that most shortlisted firms offered a FIT below THB 2.50. An overview of new solar rooftop developments gives the article “Seven Questions: Thailand’s new solar rooftop legislation”

January 2018: Announcement of a public tender for solar farms of totaling 269 MW, based on semi-firm power purchase agreements. This project has been abandoned.

March/April 2018: Thailand country report “The sunny prospects and hazy risks of Thailand’s next stage of solar growth” Also, Thailand Solar Energy Profile is featured in the March 2019 issue of the Solar Magazine.

June 2018: Statement by Thailand’s Minister of Energy

  • B2G: Private, as well as commercial and industrial rooftops, have to be “accepted” (licensed?) to sell solar power to the grid.
  • FIT: The FIT will be “up to” 2.44 THB/kWh. This FIT is explained by the fact that the costs to develop rooftop solar photovoltaic panels have declined.
  • B2B: According to the Ministry of Energy, “households are allowed to participate in the power generation from their own rooftops and to receive revenue from selling the surplus electricity.” Whether this includes private PPAs for solar panels installed on foreign rooftops and selling 100% of the generated energy has not yet been explicitly declared.
  • Timeframe: Details such as business model, investment budget, power tariff, net metering system, supporting region and capacity from each building are still under development. The investment conditions are expected to be concluded this year.
  • 2036: The government aims to increase the country’s total renewable energy power generation from now 10% to 30% in 2036. Current policies may be accelerated to increase the proportion of renewable energy and meet the target sooner than projected.

July 2018: Thailand’s Ministry of Energy aims to introduce nonsubsidized solar rooftop power, which does not rely on the Thai feed-in tariff (FIT) regime. Under such economics, electricity will be sold at a discount to the price of electricity purchased from the fossil fuel-dominated national grid, thereby achieving solar power production at parity with the grid.

May 2019: The pilot program for 100 MW of household solar rooftops has been launched. It requires a power generation capacity of 5-10 kW, which results in installation costs of THB 350,000-400,000. 15,000 participants are expected by the Energy Ministry until the end of 2019, selling up to 100 MW this year at a FIT of THB 1.68 per kilowatt-hour. The scheme can be joined online via the websites of MEA at spv.mea.or.th and PEA at ppim.pea.co.th. Power capacity under the scheme starts at 100 MW per year during 2019-27 for households and increases solar power generation to 1,000MW per year from 2028 on, ultimately reaching 10,000 MW by 2037.

July 2019: Thailand’s Ministry of Energy has amended its Alternative Energy Development Plan (AEDP) 2018. Under the 2019 version of the AEDP 2018, electricity generated from renewable energy sources will be fed into the national power grid as follows:

  • solar power generating 15,574 MW,
  • biomass generating 5,786 MW,
  • wind turbines generating 2,989 MW,
  • hydroelectric power from domestic generators and from Laos generating 3,000 MW, and
  • waste to energy generating from previously 500 MW to now 900 MW.

These renewable power sources will contribute a total of 29,358 MW or 33 percent of the national electricity generating capacity. The cost of electricity generated from renewable energy will be approximately THB 2.44 per unit. The Ministry of Energy expects that this will not affect the general public’s electricity bills.

October 2019: Due to lack of acceptance of the 100 MW household solar rooftop scheme, the program is announced to be converted in December into the community-owned power project „Energy for All“ as a hybrid power scheme utilizing both waste and solar resources.

Seven business opportunities for solar projects in 2019: From new solar farm biddings to the blockchain-driven Internet of Energy

Opportunity #1 – New land-based solar farms: Under the current legislative framework, governmental utilities have the monopoly to buy electricity. Therefore, a governmental power purchase agreement with EGAT, MEA, or PEA would be required to develop new land-based solar energy farms. This sector of renewable energy is typically subject to a public tender procedure. It has to follow pre-defined steps and offers a certain degree of transparency and fairness.

Tender procedures might request a firm or semi-firm PPA with the legal obligation to supply electricity to the governmental utility even during peak hours. This requires the combination of solar panels with biomass, biogas or similar energy generating facility backup, which results in its classification as a hybrid. Typical quota are (i) 100% output at peak time +/- 2% and (ii) 65% output at off-peak. While “firm” means throughout the year, the “semi-firm” is defined as “firm” for six months of the year (including March till June) and non-firm for the remaining six months. Underperformance might require the power producer to pay (liquidated?) damages. Future public tender procedures will have further regulatory requirements concerning location, capacity, PPA conditions, and overall feasibility.

Currently announced projects: None (This section will be updated, depending on future developments).

Opportunity #2 – Off-market solar farms: It is not a secret that several solar energy projects are realized off-market and outside of a formal public tender process. Foreign investors will need a close connection and cooperation with a Thai partner and may have to adjust their business policies to local standards. As a general aspect of investments in Thailand, the political risk of a (retrospective) cancellation of renewable energy incentives is small, but not non-existing. Section 44 of the Interim Constitution (“S44IC”) will be still in place till the elections in 2019+ and gives the army manned NCPO (National Committee for Peace and Order) full and uncontrolled authority to reshape the energy legislation and regulatory framework without grandfathering, loss compensation, legal or court protection.

Opportunity #3 – Acquisition of existing solar farms: While the last few years saw a pretty flourishing trade of electricity production licenses and power purchase agreements, several semi-finished or already established and electricity-producing solar farms are for sale. Such projects can be acquired through an asset acquisition or the transfer of the shares in the solar farm company.

Opportunity #4 – Self-consumption schemes: As a cost-effective way to leverage solar energy, commercial and industrial property owners are allowed to install solar panels onto their own roofs and to produce electricity “behind-the-meter” for self-consumption. Such investments can be delivered, financed and maintained by third parties under EPC (Engineering, Procurement, and Construction), O&M (Operating & Maintenance) and finance agreements.

Opportunity #5 – Solar rooftop investments: Under international solar rooftop legislation, (foreign) investors and developers are allowed (i) to cooperate with commercial and industrial rooftop owners, (ii) to generate electricity, (iii) to sell the electricity to the grid (net metering) and (iv) to enter into power purchase agreements with commercial and industrial parties (C&I PPA). Meanwhile, Thailand’s regulatory framework lacks these full scope of opportunities. Details can be found at “Thailand’s new solar rooftop developments.

Opportunity #6 – Floating solar farms: As the Third Way, the development of floating solar arrays (floatovoltaics) should be the next big thing. Nine new projects are on the way and details can be found at “Floating solar farms in Thailand“.

Opportunity #7 – Thailand’s power grid: The revised version of the power development plan (PDP) for 2018-37 is focused on new investments in renewable power by opening private participation and investment with local communities in order to share profit and revenue with locals. This new regulatory framework opens new business opportunities for foreign solar companies in a peer-to-peer (P2P) power trading model to decentralize the power generation system in the land of smile. This will require to set-up a Thai company to enter into a joint-venture with small communities.

P2P power trading will include biomass, biogas, waste and solar energy, depending on the potential in each province. Existing and new power-distributing infrastructure and transmission lines will be the key factor when designing the venture. Thailand’s new Energy Minister is quoted in the local press “The project will be open for participation from businesses of all sizes that are interested in the electricity value chain, so peer-to-peer power trade can combine blockchain, smart power meters and a new sandbox for the power business.”

Internet of Energy (IoE) means the implementation of the Internet of Things (IoT) technology with distributed energy systems to optimize the efficiency of the generation, transmission, and utilization of electricity. As soon as Thailand and its regulatory framework are ready for a peer-to-peer energy trading community, every person can trade their energy directly, using blockchain technology without any middleman.
