  1. Clean Energy Project Analysis Course Clean Energy Project Analysiswith RETScreen® Software © Minister of Natural Resources Canada 2001 – 2004.

  2. Objectives • Illustrate role of preliminaryfeasibility studies • Demonstrate how the RETScreen® Software works • Show how RETScreen® makes it easier to help identify & assess potential projects © Minister of Natural Resources Canada 2001 – 2004.

  3. Energy Project Implementation Process Pre-feasibility Analysis Feasibility Analysis Development & Engineering Significant barrier Clean Energy projects not being routinely considered up-front! Construction & Commissioning © Minister of Natural Resources Canada 2001 – 2004.

  4. Questions • What is an acceptable level of accuracy for project cost estimates? • How much do these studies typically cost? © Minister of Natural Resources Canada 2001 – 2004.

  5. $100 to $1,000,000! Accuracy vs. Investment Cost Dilemma

  6. Pre-feasibility Analysis Feasibility Analysis Preliminary feasibility studies When should clean energy technologiesbe assessed? • Need for energy system • New construction or planned renovation • High conventional energy costs • Interest by key stakeholders • Approvals possible • Funding & financing accessible • Good local clean energy resource, etc. © Minister of Natural Resources Canada 2001 – 2004.

  7. Project Viability (Wind Example)Depends on Several Factors • Energy resource available at project site (e.g. wind speed) • Equipment performance (e.g. wind turbine power curve) • Initial project costs (e.g. wind turbines, towers, engineering) • “Base case” credits (e.g. diesel generators for remote sites) • On-going and periodic project costs (e.g. cleaning of wind turbine blades) Wind Turbine & Tower © Minister of Natural Resources Canada 2001 – 2004.

  8. Project Viability (Wind Example)Depends on Several Factors - cont. • Avoided cost of energy (e.g. wholesale electricity price) • Financing (e.g. debt ratio & length, interest rate) • Taxes on equipment & income(or savings) • Environmental characteristics of energy displaced (e.g. coal, natural gas, oil, large hydro, nuclear) • Environmental credits and/or subsidies (e.g. greenpower rates, GHG credits, grants) • Decision-maker’s definition of cost-effective (e.g. payback period, IRR, NPV, Energy production costs) Wind Energy Photo Credit: Middelgrunden Wind Turbine Co-operative © Minister of Natural Resources Canada 2001 – 2004.

  9. Why Use RETScreen®? • Simplifies preliminary evaluations • Requires relatively little user input • Calculates key technical and financial viability indicators automatically • Costs 1/10th the amount of other assessment methods • Standardized procedures allow objective comparisons • Increases potential for successful clean energy project implementation © Minister of Natural Resources Canada 2001 – 2004.

  10. Comparing PV Energy Production Calculated by RETScreen and HOMER RETScreen® Validation- Examples • All models validated by comparison with monitored and manufacturer’s data… 100% Manufacturer 80% RETScreen 60% Efficiency (%) 40% Hydro Turbine Efficiency Curves: 20% RETScreen vs. Manufacturer 0% 0% 20% 40% 60% 80% 100% Percent of Rated Flow • … and/or by comparison with hourly simulation tools. © Minister of Natural Resources Canada 2001 – 2004.
