• ERCOT reviews the Annual Reports, Official Statements, Plant Insurance policies, etc. provided by the NOIEs for confirmation.

For NOIEs that have long-term contractual commitments before Sep 1st 1999:

• ERCOT reviews the purchase contracts, sales agreements, wholesale power agreements, etc. provided by the NOIEs for confirmation.

• The MWs are confirmed by ERCOT through the RARF and the contracts provided by the NOIEs.

How does ERCOT use the Allocation Eligibility Form?

The Allocation Eligibility Forms serves two purposes:

1. It contains the PCRR eligibility information that was agreed on between ERCOT and relevant NOIE

2. It is used to populate the PCRR eligibility information file that is uploaded into the CRR system. This PCRR eligibility information includes:

• Maximum eligible MWs • Relevant sources and sinks

10CRR Team UpdateApril 2, 2008 10

When do NOIEs submit PCRR nominations?

During the first six monthly CRR auctions (only):

NOIEs must submit PCRR nominations (for the month) no later than 15 Business Days prior to the commencement of the CRR monthly auction for the one-month term which the CRRs being auctioned are effective.

During the balance-of-year CRR auction (only):

Protocols do not specify. Propose to continue with monthly auction timing.

After which, during every annual CRR Auction*:

NOIEs must submit PCRR nominations (for the 24-month or 12-month duration) no later than 30 Business Days prior to the commencement of the annual auction.

What if PCRR nominations were not fully allocated during annual CRR Auction?

If at the time of the annual PCRR allocation, ERCOT determines that PCRR nominations are not feasible, resulting in proportionally reduced PCRR allocations, then prior to each subsequent monthly CRR Auction, ERCOT shall re-evaluate the full nomination and allocate additional PCRRs, if feasible.

11CRR Team UpdateApril 2, 2008 11

What choices do NOIEs make when submitting PCRR nominations?

For NOIEs eligible for Baseload PCRRs, they can choose: – Ratio of Option vs. Obligation (“100%” means all Options; “0%” means all Obligations)– Nomination MW (equal to or less than “Eligible MW”)

For NOIEs eligible for Capacity or Refund PCRRs, they can choose:– EITHER Capacity or Refund type (per PCRR, per auction period)– Ratio of Option vs Obligation (“100%” means all Options; “0%” means all Obligations)– Nomination MW (equal to or less than “Eligible MW”)

Note: if “Capacity” type is chosen, Nomination MW <= 40% capacity factor per year

12CRR Team UpdateApril 2, 2008 12

How does ERCOT run PCRR allocations?

• ERCOT intends to use the same CRR Network Model for each month’s PCRR allocation, MCFRI allocation and CRR Auction.

– This means that any outages, contingencies, binding constraints, etc. included in the PCRR allocation will also be included in the subsequent MCFRI allocation and CRR auction.

• ERCOT shall conduct a simultaneous feasibility test (SFT) to determine whether the nominated PCRRs comply with network model constraints.

• PCRR allocations are evaluated using 100% of network capacity

• If the SFT evaluation indicates that the nominated PCRR amounts are not feasible, then ERCOT shall proportionately reduce the requested PCRRs by their Impact Ratio on violated constraints.

13CRR Team UpdateApril 2, 2008 13

What happens after ERCOT runs the PCRR allocation?

• PCRR allocation results must be available as part of the Auction Notice posting.– No less than 10 days before the monthly CRR Auction (20 days before the annual).

• Once allocated, NOIEs may offer their PCRRs in the subsequent CRR Auction (even before paying for those PCRRs).

• After CRR Auction has cleared, PCRRs are priced (according to auction clearing price and type of PCRR) and NOIEs will receive an invoice for those PCRRs. Only after payment is made, can NOIEs bilaterally trade those PCRRs.
