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.
