Pursuant to 10 CFR 50.75(f)(1), each power reactor licensee is required to report to the NRC on a calendar year basis, beginning on March 31, 1999, and every two years thereafter, on the status of its decommissioning funding for each reactor or share of reactor it owns. The requested information is provided below.

1. Minimum decommissioning fund estimate Total Required: $53,393,601 pursuant to 10 CFR 50.75(b) and (c)1:
2. Amount accumulated at the end of the calendar Amount Accumulated2: $86,973,803 year preceding the date of the report for items included in 10 CFR 50.75(b) and (c):
3. Schedule of the annual amounts remaining to be Amount Remaining3: $0 collected for items in 10 CFR 50.75(b) and (c):

Number of Years to Collect: 26.65

4. Assumptions used regarding escalation in Escalation Rate4: 2.540%

decommissioning cost, rates of earnings on decommissioning funds, and rates of other Earnings Rate: 3.628%

factors used in funding projections:

5. Contracts upon which the licensee is relying None pursuant to 10 CFR 50.75(e)(1)(v):
6. Modifications to a licensees current method of None providing financial assurance occurring since the last submitted report:
7. Material changes to trust agreements: None
1. The NRC formulas in section 10 CFR 50.75(c) include only those decommissioning costs incurred by licensees to remove a facility or site safely from service and reduce residual radioactivity to levels that permit: (1) release of the property for unrestricted use and termination of the license or (2) release of the property under restricted conditions and termination of the license.
2. By Order dated October 10, 2008, in PUCT Docket No. 35772, NRG South Texas was granted approval to establish a separate spent nuclear fuel management (SNF) subaccount. By Order dated July 13, 2009, in PUCT Docket No.

36796, NRG South Texas was granted approval to establish a separate subaccount for the pre-shutdown disposal of large components. By Order dated October 7, 2013, NRG South Texas was granted approval to establish a separate subaccount for amounts recovered pursuant to a litigation settlement agreement with the United States government for certain onsite spent fuel storage and management expenses it has incurred and will incur as a result of the failure of the Department of Energy to provide for the offsite disposal of spent nuclear fuel. The amounts allocable to the subaccounts are not included in the reported amount. The reported amount includes funds accumulated based upon a site-specific study that includes license termination and other costs.

3. NRG estimates that the Trust is currently fully funded, based on the 2018 decommissioning cost study and updated escalation rates. Additional contributions ended December 31, 2008. If future estimates indicate that further funding may be required, NRG would be able to apply to the PUCT to seek further funding for NRC license termination costs through cost-of-service recovery authorized by Texas law.
4. Escalation and earnings rates were established by the PUCT in PUCT Tariff Control No. 41970.
