Transmission Design

This document presents an analysis of the original expansion of conventional generation and the integration of wind generation in the Great Lakes region, assuming a 20% capacity value for wind. The EGEAS expansion identifies the regional generation needed for reliability, including LOLE and ELCC analysis. Webinar discussions clarify the pricing and quantity of sources and sinks determining transmission requirements across four scenarios. The year-to-year variability in ELCC is attributed to hourly load and wind profiles from 2004 to 2006, revealing insights into CO2 reduction strategies for 2024.

  7. Year to Year ELCC Variability • Year to Year variation in the ELCC results is due to • The different Hourly Load & Wind Profiles (2004, 2005 & 2006) • And where the wind is located in each of the different Scenarios • As can be seen in the results a shift • As more wind was located in the East (Scenario 3 & 4)The 2006 profile contained the higher ELCC • As more wind was located in the West (Scenario 1)The 2004 profile contained the higher ELCC
