2019-2020 CIL/CEL Values
and Study Timeline
1
Updated
10/3/2018
• Purpose
• Inform stakeholders of Draft 2019-20
Capacity Import and Export Limits.
Key Takeaways (Limit changes)
• Limits have been impacted by the
FERC Locational filing changes
(MISO process change).
• Limits have been impacted by MISO
system changes including
transmission topology and generation
dispatch.
2
Purpose and Key Takeaways
Introduction
• Capacity Import and Export Limits (CIL and CEL) in this
presentation are calculated based on the FERC Locational
filing.
• The CIL and CEL results have been adjusted for exports to non-
MISO load.
• Coordinating Owner Resources and Border External Resources
are no longer treated as imports and instead treated as internal to
the zone which impacts base area interchange.
• CIL/ZIA for LRZs 1, 2, 3 and 4 along with CEL/ZEA for LRZs 4
and 5 have all been updated as of 10/03/18.

Limit: 2,122 MW
• A valid constraint was not found.
• Initially, Capacity Export Limit was determined as the sum of
the Base Area Interchange and the excess capacity in LRZ 5.
• This was discussed at the 9/11/18 LOLEWG and the 9/12/18
RASC meetings and it was agreed that without any major
changes from last year within LRZ 5, the previous limits would
be utilized.
