Technical regulations:
• Allowable voltage,
frequency, THD
variations
• Protective relays
• Communication
channels
Commercial regulations:
• Definitions of
renewable energy, and
efficient cogeneration
• Cost allocation
• Standardized tariff
determination
• Invoicing and payment
arrangements
• Arbitration
+ Standardized Power Purchase Agreement (PPA)
Access to
grid
Small Power Producer (SPP) regulations:
• Started 1992
• Fossil-fuel cogeneration and renewable energy
up to 90 MW (export to grid)
• Low tariff offered for “non-firm” generators
made it difficult for most renewables.
Bangkok Cogen, Rayong, 115 MW
Laem Chabang, Chonburi 100 MW
4494 MW online + 4152 MW with signed PPAs... 75% fossil fuel
Map Ta Phut Olefins, Rayong, 70 MW
Pluak Daeng, Rayong 70 MW
(over 1,000 rai = 160 hectares)
• Signed PPAs for 767 MW of PV (SPP + VSPP)
Lopburi solar PV – 73 MW

Feed-in
tariffs
Evolution of Thai VSPP regulations
• 2002
– VSPP regulations drafted, approved by Cabinet
– Up to 1 MW export, renewables only
– Tariffs set at utility’s avoided cost
• 2006
– Up to 10 MW export, renewables + cogeneration
– Feed-in tariff “adder”
• 2009
– Tariff adder increase, more for projects that offset diesel

investment in:
• Energy efficiency improvement projects
• Renewable energy development and utilization projects
11 local financial institutions have participated.
Max loan amount: 50 MB
Max. interest rate: 4%
Max. loan period: 7 years
January 2003 – present

Tax Incentives
Thailand’s Board of Investment (BOI)’s tax incentives for
renewable energy projects:
• Corporate income tax holidays up to 8 yrs. Additional 50%
reductions of corporate income tax for 5 yrs
• Import duty reductions or exemptions on equipment and raw
materials

Korat Waste to Energy – biogas
… an early Thai VSPP project
• Uses waste water from cassava
to make methane
• Produces gas for all factory heat
(30 MW thermal) + 3 MW of
electricity
• 3 x 1 MW gas generators

Problems
• “Managing committee” set up after solar “gold rush” to be
additional gate keeper. Non-transparent, not clear why some
projects proceed and others are denied.
• Biomass: many projects unprofitable because high cost of
biomass.
• Communities protesting some biomass power plants.
– Now no EIS required if <10 MW  Many 9.9 MW plants.
– EIS should be required for smaller plants too if pollution is a concern.
• Mainly huge projects (e.g. solar farms, not rooftop PV), which
may have more concentrated impacts. Redesign feed-in tariff
to incentivize small projects.
Evolution of Tanzania SPP regulations
• Approved by regulator August 2009
• Up to 10 MW export, renewables &
cogeneration
• SPP Tariffs at average of LRMC and SRMC
– Grid-connected SPP tariff (2012): $0.096/kWh
– In rural mini-grid areas offsetting diesel (2012):
$0.243/kWh
• 4 SPPs in operation, 12+ in pipeline by
December 2012
