Throughout the West’s diverse energy resource portfolio, recent years have shown a shift away from large baseload resources (e.g., coal, nuclear) toward more renewable resources. This transition requires new methods of resource planning. In response, the Western Electricity Coordinating Council (WECC) developed a probabilistic tool for performing resource adequacy assessments, an interactive portal for viewing different future resource scenarios, and an interconnection-wide assessment of resource adequacy over the next 10 years. The assessment is called the Western Assessment of Resource Adequacy, or Western Assessment. Based on the findings of the Western Assessment, traditional resource planning will not be adequate due to increasing variability in the system. If we want to keep high levels of resource adequacy, resource planning methods and practices must change.
