Background
| Status: | Approved |
|---|---|
| Date Posted: | Sep 28, 2012 |
| Sponsor: | Luminant Energy Company, LLC |
| Urgent: | No |
| Sections: | 7.5.5.3, 9.9, 9.9.1, 9.9.2, 16.11.4.5 |
| Description: | This Nodal Protocol Revision Request (NPRR) replaces the Congestion Revenue Right (CRR) Auction credit calculations with path-specific exposure calculations based on Day-Ahead Market (DAM) clearing prices over a rolling period and revises the Future Credit Exposure (FCE) calculations for CRR Account Holders; which results in a modification to the payment schedule for CRRs. |
| Reason: | The current credit calculations collateralize in a uniform manner and do not recognize that different congestion paths have various levels of risk. This can lead to under-collateralization of the riskiest paths, leaving the market exposed, or significant over-collateralization, therefore increasing the cost of participation for many Market Participants. In addition, this proposal allows Market Participants to post collateral in lieu of pre-paying for forward awarded CRRs. |
