History of Thailand’sVSPP Program
EPPO
• 2002 » VSPP Regulation introduced
» Applicable to renewable and co-generation facilities
» up to 1MW contracted capacity
• 2006» contracted capacity extended from 1 MW to 10
MW» Feed-in Tariffs (“ADDER”) introduced
• 2009» Adder rates adjusted
» Some rules and regulations adjusted (bid bond, , dispatch, and rooftop solar)

Recent Changes and Lessons Learned
EPPO
Some Recent Changes, Lessons Learned, and the
Way Forward1. VSPP’s simplified application process has been
updated to discourage speculators2. Rooftop solar systems now receive adder based
on total kWh generated, not on net-metered kWh
3. Financial measures not enough4. Technical regulations subject to revision5. “ADDER” rates set to balance investment
against other public policy objectives6. Certain benefits of RE have yet to be quantified
and integrated into long-term power supply adequacy plan
EPPO
1. Simplified rules updated• VSPP regulation was previously designed to
simplify the application process in order to encourage small-scale RE systems to develop
– Previously designed for up to 1 MW contracted capacity– Previously designed before ADDER was introduced
• In 2009, some modifications to the rules have been made to discourage speculators:
Bid bond 200 Baht/kW sale except system sized <100 kW No adder will be given if the project cannot start selling power within 1 year after the SCOD (applicable to proposals without PPAs after Aug 2009)

2. Rooftop Solar Systems• Residential rooftop solar systems previously received adder based on the net-metered kWh
• As of Aug 2009, rooftop solar energy systems can receive adder based on total kWh generated
some controversies regarding “residential rooftop” definition
Official definition: residential rooftop systems belong to those systems that subscribe to residential meters
Implementation? Abuse?
EPPO
3. ADDER as one of the supporting measures for RE
• Other financial measures and non-financial measures are needed to accelerate RE development

4. Technical Regulations Subject to Revision
• Interconnection limits:– 8 MW ceiling for 22 kV feeder– 10 MW ceiling for 33 kV feeder
-Technically acceptable level of RE may vary from feeder to feeder
- Technical regulation based on “passive integration” rather than “active integration”
Benefits of RE for each feeder not taken into account
Benefits: line loss reduction, voltage regulation, peak cutting.
EPPO
5. ADDER Rates Subject to Revision
• In response to changing market conditions, technological change, and
remaining RE potential
Benefits of increased in RE investment are balanced against:
BENEFITS COSTS
-reduction of energy imports
-increase in FDI
-potential job creation and new business models
-potential local innovation
-reduction of GHGs and air pollution
-technical benefits to power systems
-pass-through to ratepayers
-trade deficits
-loss of agricultural land
-local air pollution ( systems <10 MW not subject to EIA)
