The story of Thailand’s centralized power sector
Palang Thai Chuenchom Sangarasri Greacen 5 October 2009 MeeNet, Thailand
2
1. The origin
3
Bangkok’s first paved road (New Road)
Electricity was introduced by King Rama V. Electric tram in Bangkok (powered by a wood-fired steam engine) in 1884.
4
Late 1800s – early 1960s Initially electricity served mainly the elites With series of wars and coups, not much happened in terms of spreading electricity By early 1960s, only 2% of Thais had electricity No consensus on form of ownership: private or state or coop model Diverse forms of ownership: over 200 separate small cooperative, municipal or privately owned utilities
5
At a cross road: centralized or decentralized model?
Like the US Bonneville Power Authority, Thai National Energy Authority (NEA) was created to regulate hundreds of small utilities and built early power plants. Also served as the MRC secretariat and pushed large dam projects on the Mekong. With WB advocating central planning, fragmented state-owned enterprises Metropolitan Electricity Authority, Yanhee Electricity Authority, Northeast Electricity Authority, and the Lignite Authority
6
Decentralized Micro-hydro technology
Micro-hydropower harnesses energy from falling water. Typcially some water is diverted from a stream using a weir. Water is then transported by a channel or pipes to a powerhouse downstream where the pressurized water spins a turbine, generating electricity. Source: Inversin, A. R. (1986). Micro-Hydropower Sourcebook. 6

Centralized generation
High voltage transmission Transformer Centralized generation Medium voltage distribution
8
Deciding factor: Cold War politics
USAID poured in billions of dollars to Thailand, seen as a regional power to be courted in containing communism USAID advisors considered micro-hydroelectricity but dismissed the option for large central generation with transmission and distribution In contrast to China’s extensive adoption of community-owned village-scale micro-hydro The USAID pre-feasibility study adopted verbatim as Thailand’s rural electrification master plan Electricity used to win the hearts & minds in “red/pink areas”
9
The birth of centralized utilities
Creation of Electricity Generating Authority of Thailand (EGAT) By merging 3 SOEs With Metropolitan Electricity Authority (MEA) & Provincial Electricity Authority (PEA) in charge of distribution
10
Moral of the story… Centralized grid: in many cases, makes economic and technical sense, however… Control of a central grid need not be monopolized by one group Structure of centralized control determined by Cold War politics, not technical superiority Electricity played a political role
11
2. The Evolution
12
1970s – 1980s Centralized structure and control facilitated rapid expansion of grid, rural electrification Monopoly status with state power to provide essential public service Generous support from WB in particular Cost-plus structure State-owned utilities also grew in size and political power
13
1990s – Neo-liberal agenda With rise in global private capital, WB & IMF pushed privatization agenda Sale of EGAT’s assets: EGCO, Ratchaburi Giving “concessions” to private power producers (IPPs, SPPs) to generate & sell power Plan to create “Power Pool” and privatize the 3 utilities
14
2000s – National champion EGAT resisted neoliberal reforms
Power Pool plan aborted EGAT aspired to be partially privatized “National Champion” but effort thwarted by civil action Still an SOE, EGAT has monopoly and public rights but with profit-seeking aspirations Use of profit-seeking subsidiaries to expand and pursue commercial interests Large capital and captive consumer base allows EGAT/its subsidiaries to invest abroad in competition w/ other transnationals
15
Power Grid & Pipelines are analogous to a giant’s arms reaching to grab resources to feed its endless appetite.
16
Changing role of electricity
Electricity changes from a public service to a profit-making commodity With cross-border grid extension or regional grid, “Energy commons” (e.g. rivers w/ hydroelectric potential, natural gas) in countries surrounding Thailand are become a transnational commodity
17
3. The Character
18
Unchecked centralized power
“A minority must sacrifice for the greater good” “out of sight, out of mind” Results: Structural violence Inequality waste

4. The driver
28
Cycle of (over-)expansion under the centralized monopoly system
Deterministic planning based on demand forecast leads to over-investment in capital-intensive power projects Power demand (over-)projections 1 2 Utilities’ Profits 3 Tariff structure that allows pass-through of unnecessary investments
29
Incentive structure for utilities: the more expansion, the more profits
Financial criteria for utilities link profits to investments Thailand uses outdated return-based regulation WB’s promoted financial criteria such as self financing ratio (SFR) also have similar effects ROIC (Return on Invested Capital means: the more you invest, the more profits ROIC = Net profit after tax Invested capital EGAT 8.4% MEA PEA 4.8% Result : Demand forecast have systemic bias toward over-projections Too many expensive power projects get built

Power demand projection Sep 2007 (PDP 2007 revision 1)

Power Demand: Projections vs
Power Demand: Projections vs. Actual 1992 – 2008 If no systemic bias, the chance of over-projecting demand 12 times in a row should be 1/4096!! MW
32
Why assume exponential growth? Linear vs. exponential extrapolation
31 power plants
33
Planning of capacity additions
(Total capacity requirement = peak demand + 15% reserve margin)
34
Many questions for PDP 2007 Why only 1700 MW of distributed generation allowed? Why 4000 MW of nuclear in all options? Why DSM/energy efficiency not considered as an option? New capacity added to the PDP 2007 L = low case B = base case H = high case 1=“lowest cost” 2=“as much coal as acceptable” 3=“LNG + imports”

Lack of accountability in demand over-projection and over-investment made of possible by guaranteed rate of return for utilities ROIC = Net profit after tax Invested capital EGAT 8.4% MEA PEA ROIC (Return on Invested Capital means: the more you invest, the more profits 4.8% Guaranteed rate of return means central planners are rewarded, not held accountable, for their repeated errors in demand forecast
