WIRAB provided Advice to the WECC Board on the development of a Western Focused LTRA. Western utilities have been relying on market purchases (i.e., Front Office Transactions) to meet resource adequacy requirements. If multiple utilities rely on the same market supply for resource adequacy, then one or more utilities may be left short when supply and demand conditions are tight across the West. The NERC LTRA has contributed to the perception that there are significant surpluses of capacity in the Western Interconnection. Therefore, WIRAB provided four steps WECC can take to improve the assessment of regional resource adequacy in the West.
