Rethinking “energy security” and power
sector planning:
a case study of Thailand
18-19 January 2012
Chuenchom Sangarasri Greacen
Palang Thai
"Know Your Power“ International Conference
Towards a Participatory Approach
for Sustainable Power Development in the Mekong Region
Brief history of Thai power sector
• 1960s: decentralized coops in close competition with
centralized utilities as the model to electrify
Thailand.
• Centralized model chosen not by technical superiority but
rather by Cold War politics
• 1960s-90s: rapid expansion of power system by
state-owned utilities
• World Bank and aid agencies had major roles
• 1990s: neoliberal reforms
• Partial divestiture of EGAT’s generation assets (EGCO, RATCH)
• Small and Independent Power Producers (SPPs/IPPs)
• Role of private foreign capital
Brief history of Thai power sector (2)
• 2000s-present:
• Plan to create Power Pool abandoned
• Attempt to partially privatize (equitize) monopoly EGAT in
the stock market thwarted by civil society’s lawsuit
• But increasing financialization of electricity in the stock
market continued via EGAT’s subsidiaries, other Thai
energy companies and their joint ventures with foreign
capital
• Increasing roles of Thai listed non-energy companies (e.g.
construction) in power project investment
• Mushrooming power projects, domestic & trans-boundary
ISSUES AND TRENDS IN POWER SECTOR
PLANNING AND DEVELOPMENT
Changing role of electricity
• Electricity as public service  profitable
commodity
• Commons like rivers  trans-boundary
commodities
Changing role of policy makers:
Serving public or corporations?
Performance of high-level energy officials in
serving the government vs. PTT Plc. (Thai
gas/oil utility, the largest list company in Thailand)

Power projects and policies driven by
companies
• Power Development Plan (PDP) used to be the
master plan for capacity expansion
• Determines how many of which kind of plants get
built when
• But now some projects were on “fast track”
even before being listed in the PDP, e.g.
• 1,260 MW Xayaburi dam
• 4,000 MW coal-fired plants in Dawei
Energy policy and plans become tools to drive the
stock market and churn profits
• The coup-installed government announced its policy on
energy investment opportunities on 3 Oct 2006
• Energy policy, PDP approval and IPP bidding resulted in
significant windfall benefits for selected companies
• 1 year later, the share prices of companies benefiting from
the PDP jumped 66% (other companies had a 8.7% rise)

Investment disconnected actual need
for electricity
• Criteria for determining generation
requirement:
• Reserve margin (capacity in excess of peak demand) ≥ 15%
• Yet Thailand’s PDP2010 adds generation:
•
•
•
•
•
920 MW Nam Theun 2 when reserve margin > 28%
597 MW Nam Ngum 2 when reserve margin > 27%
660 MW Gheco1 when reserve margin > 27%
1600 MW SiamEnergy when reserve margin > 25%
and many more….
Planned new investments are so excessive
despite exaggerated “needs”
Used to justify NT2
5,800 MW
The year NT2 came online
Over-investment = unnecessary impacts,
burden on consumers
and economy
Thai power sector suffered from
“over-capacity worth 400 billion
Baht” (from total assets of 700 billion
Baht and annual turnover of 240
billion Baht)

- % energy imports
- Concentration (plant)
Affordability

- % exposure to oil price
Efficiency
- Energy & economic efficiency
- Energy intensity

New & improved PDPs
• New PDP based on more realistic demand
forecast = “PDP2012”
• Improved PDP based on PDP2010 forecast =
“PDP2010v2”
Methodology
– Maintain 15% minimum reserve margin
– Prioritize investment in energy efficiency (EE)/ demandside management (DSM) as a resource option
– Consider life extension (delayed retirement) of power
plants as a resource option
• Additional investment might be required but only done in cases
that are economic compared to building a new power plant.
– When additional capacity is needed, prioritize (highefficiency) cogeneration over (inefficient) centralized
generation
– New generation not already under construction may be
removed if not needed to maintain 15% reserve margin

• PDP2010 did acceptable job of including more

• RE projects also have impacts and face

Concluding remarks
• Worrying trend of commoditizing electricity
• “Energy security” and PDP process distorted to
generate profits for a few at the expense of
– Affected communities
– Consumers
- Environment
- Economy
• Need framework to hold “energy security” and PDP
accountable to Energy Industry Act & the public
• Need to reform PDP process to prioritize cheaper,
cleaner options to meeting demand
• Proposed PDP2012 better achieves energy security
without the need for new green-field centralized coal/
gas/dam/nuclear.
