Accounts Receivable, after Allowance for Credit Loss [Abstract] |
Accounts Receivable, Net | The table below summarizes the types and amounts of TVA's accounts receivable:
Accounts Receivable, Net
| At March 31, 2021 |  | At September 30, 2020
Power receivables | $ | 1,204 |  |  | $ | 1,401 |
Other receivables | 80 |  |  | 128 |
Accounts receivable, net(1) | $ | 1,284 |  |  | $ | 1,529 |
Note (1) Allowance for uncollectible accounts was less than $1 million at March 31, 2021, and September 30, 2020, and therefore is not represented in the table above. The allowance at March 31, 2021 includes the impact from adopting CECL on October 1, 2020. In response to the COVID-19 pandemic, the TVA Board approved the Public Power Support and Stabilization Program in 2020. Through this program, TVA offered up to $1.0 billion of credit support to local power company customers ("LPCs") that demonstrated the need for temporary financial relief, through the deferral of a portion of LPCs' wholesale power payments owed to TVA. The program ended on December 31, 2020, with a total of $1 million of credit support approved under the program. As of March 31, 2021, the $1 million had been fully repaid.
