What was the main event reported in this 8-K filing?

This 8-K filing reports on the decisions made by the Georgia Public Service Commission (PSC) on December 21, 2017, regarding the ongoing construction of Plant Vogtle Units 3 and 4. Key approvals included capital costs, continuation of construction, customer refunds, revised project timelines, and adjustments to cost recovery mechanisms.

How will the approved changes affect customer costs?

The Georgia PSC approved approximately $188 million in customer refunds to be paid during 2018. Additionally, while the revised capital cost forecast is not a cost cap, future retail base rates will be adjusted to include carrying costs on prudent capital costs once Unit 3 reaches commercial operation.

What are the new projected in-service dates for Plant Vogtle Units 3 and 4?

The Georgia PSC approved a revised schedule placing Unit 3 in service in November 2021 and Unit 4 in service in November 2022.

How does the PSC's decision impact the profitability of the Plant Vogtle project for Southern Company's subsidiary, Georgia Power?

The PSC's decision impacts profitability through several measures: the revised capital cost forecast for Georgia Power's share is $7.3 billion, customer refunds totaling $188 million will be issued, and crucially, the return on equity (ROE) used for calculating nuclear construction cost recovery and allowance for equity funds used during construction will be reduced in stages, which will lower the allowed returns during the construction period.
