Seasonal Outlook SERC’s 2020 Summer Outlook identifies, assesses, and reports on areas of concern regarding the reliability of the SERC Region for the upcoming summer season. In addition, this assessment presents peak electricity demand and supply changes, and highlights any unique subregional challenges or expected conditions that might affect the BPS. The reliability assessment process is a coordinated reliability evaluation between the RRS, the subregions, and SERC staff. This report reflects SERC’s independent assessment; its intent is to inform industry leaders, planners, operators, and regulatory bodies so they are better prepared to take necessary actions to ensure Bulk Power System reliability. The report also provides an opportunity for the industry to discuss their plans and preparations to ensure reliability for the upcoming summer period. The assessment indicates that each of the SERC subregions have a plan to address resource adequacy risk during the peak conditions, even when Planning Reserve Margins exceed Reference Margin Levels. The reasons can be similar: generator scheduled maintenance; forced outages due to normal and more extreme weather conditions and loads; and low-likelihood conditions that affect generation resource performance or unit availability, including constrained fuel supplies. The Regional Assessment Dashboards section in the NERC Summer Reliability Assessment includes a seasonal risk scenario for each area that illustrates variables in resources and load, and where appropriate, the potential effects that operating actions can have to mitigate shortfalls in operating reserves.
