Integrated Resource Planning (IRP) -- a tool for Lao power sector planning? Lessons from the USA Pacific Northwest Chris Greacen Vientiane, Lao 5 March 2013
Outline • A brief history of the power sector in Pacific Northwest of USA • Integrated Resource Planning (IRP) • What is it? • What steps are involved? • Example: IRP and energy efficiency in the Pacific Northwest
History of Integrated Resource Planning • Pre-1980, utilities used “straight-line” load forecasts (a ruler) to make resource decisions
Straight-line demand forecasting led to huge financial commitments to very large power plants
IRP History-con’t. • Utilities and regulators ask, “Is there a better way?” • 20 Years ago WUTC adopted rules to require investor-owned utilities to prepare a Least Cost Planning or “Integrated Resource Plan (IRP). • consider demand elasticity • consider demand side resources
As of 2011, 39 States Require IRP Source: Wilson & Pederson, 2011. A Brief Survey of State Integrated Resource Planning Rules and Requirements
What is Integrated Resource Planning (IRP)? Simply put, IRP means meeting power sector objectives at the lowest cost. • Consider a range of different options • Include all costs (generation, transmission, social & environmental costs) • Chose option the provides best benefit at lowest cost/risk profile
Objectives Defined IRP Flowchart ITERATION Data collection, systems analysis Demand forecast scenarios (by end use) Meeting electricity requirement: options T&D IMPROVEMENTS END-USE EFFICIENCY IMPROVEMENTS GENERATIONPLANTS UNIT COSTS OF ALTERNATIVES ($ / kWh) GWh YEAR B A C LEAST COST MIX $/kWh GWh Strategies Periodic Monitoring Source: D’Sa, A. (2005). "Integrated resource planning (IRP) and power sector reform in developing countries." Energy Policy 33(10): 1271-1285. Implementation
“Full Featured” IRP status • the state IRP process is required by law • the process is subject to public review; • regulators require integration of construction permit and utility ratemaking processes with the IRP process
Example: IRP and energy efficiency in the Pacific Northwest • IRP objective: minimize cost to meet growing electricity demand

Lessons Learned – Power System Planning • Energy Efficiency Reduces System Cost and Risk • Efficiency Resources Are A Low Cost (avg. 2.4 cents/kWh) Hedge Against Market Price Spikes • They’re Not Subject to Fuel Price Risk • They’re Not Subject to Carbon Control Risk • They Can Be Significant Enough In Size to delay “build decisions” on more expensive and higher risk generation • It takes REAL MONEY, DATA and ANALYSIS to properly size efficiency resources • Northwest invested about $14 per capita in 2005 acquiring efficiency, several other US states are spending more

Laos: Candidate IRP questions • What is quickest and/or most cost-effective way to provide basic electrical services to the people without electricity? • What is the most cost-effective way to meet current and growing needs for electricity in the country (industrial, commercial, residential)? • What is Laos’ optimum strategy for power export?
IRP-inspired group activity • Three tables • Rural electrification • Meeting domestic demand • Power export • ?
At each table… • Situation in a few sentences • Resources (demand and supply side) and costs • Scenarios • Indicators for monitoring whether objectives are being met
