Power Sector Planning and Development: Lessons from Thailand’s and international experience Chuenchom Sangarasri Greacen 9 March 2013 WORKSHOP ON “ELECTRIC POWER DEVELOPMENT & CHALLENGES IN MYANMAR: SHARING EXPERIENCES OF THE MEKONG REGION” Tonga Puri Hotel, Nay Pyi Taw, Myanmar
2
The engine of sustainable economic & social development Environment People (peace, democracy, justice) Improved living standards & economic opportunity: -Wealth generation -Access to electricity -Education -Health Electricity
3
Power sector planning in a nutshell Mechanism: Assess needs, Source supply To meet objectives (e.g. reliability, job creation) At reasonable price Approaches to planning: Centralized (top-down) Decentralized (bottom-up) Approaches to electrification Off-grid/mini-grid Grid extension

Power sector planning in a nutshell Mechanism: Assess needs, Source supply To meet objectives (e.g. reliability, job creation) At reasonable price Approaches to planning: Centralized (top-down) Decentralized (bottom-up) Approaches to electrification Off-grid/mini-grid Grid extension There may not be a “one-size-fit-all” solution Diverse context and situation require diverse approaches What is the best approach for a country?
6
Large Plants Customers Small Power Producer Mini-Grid Customers Parallel approach: extending the grid and encouraging rural mini-grids National Grid Top-downBottom-up
7
Thailand’s approach Rural electrification = grid expansion + mini-grid – Community-scale power generation systems (e.g. microhydro) were forced to abandon their generation and mini-grids when grid electricity arrived Centralized, monopoly (single buyer) model with strong emphasis on large-scale generation Deterministic forecast, top-down planning process Little participation in decision-making and sector development
8
Planning of capacity additions (Total capacity requirement = peak demand + 15% reserve margin)
9
Demand forecast Demand treated as given Deterministic model – Main assumptions: GDP growth Energy elasticity (electricity growth/GDP growth) Population growth Econometric model with some end-use data (e.g. floor space for offices or appliance ownership and efficiency for residential sector) if available

11
Energy demand is 1.4 times higher than GDP growth Source : EIA,DOE, BP Statistic Review of World Energy, EGAT Energy Elasticity = ∆ t Energy Consumption/ ∆ t GDP Ave. Energy Elasticity 1.4 : 1.0 New Target 1 : 1 or lower Thailand The government used to assume a constant Energy Elasticity of 1.4 but the assumption did not hold.
12
Choice of supply options considered in the PDP by EGAT 700 MW Coal-fired power plant 700 MW gas-fired combined cycle plant 230 MW gas-fired open cycle plant 1,000 MW nuclear plant Hydro imports are politically negotiated outside of PDP process DSM/EE, RE, Distributed generation not integrated in the optimization process
13
EGAT (also MEA & PEA) became “Poster-child” of World Bank, other foreign aid institutions – Access to soft loans, technical assistance, etc. – Rapid growth of sector and electrification rates – Rapid economic growth and industrial development Outcome of Thai top-down, centralized, monopoly model

Thailand’s Fuel Mix for Power Generation
15
Many successes but there are also lessons learned… Over-projection of GDP and demand forecasts leading to cycle of over-investments Abandonment and discrimination of community- scale, decentralized energy systems High dependency on imports Impacts and conflicts Inequality Inefficiency Uncompetitive and debt-ridden economy

Past demand forecasts compared to actual peak demand (MW) Used in PDP2010 Actual demand
18
Over-projections of demand leads to… Over-expansion Cycles of over-investments and burden on ratepayers No incentive to promote energy efficiency and renewable energy Unnecessary social, environmental impacts – Conflicts, violence and inequality

26
Thailand’s power sector: sustainable economic development? Evident economic, material development… …but not sustainable – Needs to rely on ever-increasing energy imports – Vulnerability to supply disruptions due to high level of centralization Unproductive, inefficient consumption only made possible by borrowing from the past (plundering resources) and the future (debt to be repaid) – Government debt now >40% of GDP – Household debt at 20-23% of income, to rise to 40%

Not all energy demand/GDP $$$ are equal: some industries have high energy, environmental costs but low value to economy BOI investment privileges should take into account energy, economic value considerations High energy intensity Low value added Low competitiveness Iron smelter industry Demand for electricity is not a given. We can choose wisely what kind of industries or economic activities are worth supporting (e.g. given investment privileges) based on their energy, environmental costs and value to economy (local job creation, local content, value creation)
30
Government Policy Framework according to Energy Industry Act 2007 4 dimensions of energy security Energy Industry Act 2007Indicators Availability- Resource Adequacy - Min. dependency on imports - Diversification - Reserve margin ≥15% - % energy imports -Shares of fuels Affordability- Affordable cost of service - Min. exposure to price volatility - Electricity cost (B/mo.) - % exposure to oil price Efficiency- Energy & economic efficiency- Energy intensity (GWh/GDP) Environment- Min. environmental impacts- GHG emissions - SO2 emissions Need to make “energy security” and PDP accountable to government policy framework Need to make “energy security” and PDP accountable to government policy framework Framework for evaluating PDPs

Large Plants Customers Small Power Producer Mini-Grid Customers Parallel approach: extending the grid and encouraging rural mini-grids National Grid Top-downBottom-up
45
Special considerations for Myanmar “The last frontier” How to leverage external resources while maximizing benefits to the locals and without losing sovereign power How to generate income while having sufficient resources to sustainably meet growing domestic needs
46
Strategy for Myanmar’s power sector planning, policy and development Integrated economic and energy policy and planning – Minimize waste, maximize efficiency – Choose economic activities wisely: low energy & resource intensity, high economic value, high competitiveness – Maximize economic value for each energy investment: “getting the most bang (jobs, investments, purchasing) for the $$$ invested” Prioritize utilization of distributed renewable over non-renewable resources Empower participation by citizens, entrepreneurs and communities in power sector planning and development

Centralized energy is also more costly Thailand PDP 2007 requires 2 trillion baht to implement, comprising: million B generation 1,482,000 transmission 595,000 Transmission adds 40% to generation costs Decentralized generation brings down costs Ireland – retail costs for new capacity Source: World Alliance for Decentralized Energy, April 2005
52
ROIC = Net profit after tax Invested capital EGAT 6.4% MEA PEA 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 Incentive structure for utilities: the high their investment budget, the more profits 5.8% Result : EGAT favors capital-intensive investments (centralized plants) by its organization or subsidiary companies. Allowing more EE or RE generation hurts EGAT’s bottom line

Important conceptual framework Rural electrification ≠ grid expansion Rural electrification = off-/mini-grid + grid expansion Planning for domestic electricity demand (electrification) = Power Development Plan (PDP) process Planning for hydropower export should be treated separately, with consideration of other ways of generating income (e.g. tourism, agriculture, industrial development) as alternatives
63
Power sector development strategy Energy security – Ability to meet demand through sustainable and efficient utilization of resources at reasonable cost Alternative energy development Energy prices and safety Conservation and efficiency Environmental protection
64
Thailand’s experience Emphasis of top-down centralized model Treating demand as given Emphasis on expansion and unsustainable centralized technology options Lack of meaningful participation
65
Strategy Efficient, sustainable utilization of resources – Self-reliance Self-reliance – Efficiency (production and consumption) – Sustainable utilization of natural resources – Value to economy – Leveraging external resources – Role of private sector – Myanmar being “the last frontier”

ในความเป็นจริง มีความไม่แน่นอนจาก เหตุการณ์ “ ที่ไม่คาดหมาย ” การพยากรณ์ไฟฟ้าหรือเศรษฐกิจมักจะไม่ได้นำเหตุการณ์ “ ที่ไม่ คาดหมาย ” มาพิจารณาเพราะยากแก่การคาดหมาย – ตัวอย่างเช่น วิกฤตการเงินในปี 2540 การพุ่งสูงของราคาน้ำมันโลก ความรุนแรงทางการเมือง และอุทกภัยร้ายแรงในรอบ 50 ปี ในอนาคต ความไม่แน่นอนจากภาวะเศรษฐกิจโลก สถานการณ์ ด้านการเมืองในประเทศ และสภาพภูมิอากาศที่แปรปรวน คาด ว่าจะยังมีอยู่ต่อไป
