project was abandoned in July 2017, 4 years after it began, due to Westinghouse's recent bankruptcy, major cost overruns, significant delays, and other issues. The project's primary shareholder (SCANA) initially favored a plan to abandon development of Unit 3, while completing Unit 2. The plan was dependent on approval of a minority shareholder (Santee Cooper). Santee Cooper's board voted to cease all construction resulting in termination of the entire project. All four reactors were identical and the two projects ran in parallel, with the first two reactors (Vogtle 3 and Summer 2) planned to be commissioned in 2019 and the remaining two (Vogtle 4 and Summer 3) in 2020. After Westinghouse filed for bankruptcy protection on March 29, 2017, the construction has stalled. On April 9, 2008, Georgia Power Company reached a contract agreement with Westinghouse and Shaw for two AP1000 reactors to be built at Vogtle. The contract represents the first agreement for new nuclear development since the Three Mile Island accident in 1979. The license request for the Vogtle site is based on revision 18 of the AP1000 design. On February 16, 2010, President Obama announced $8.33 billion in federal loan guarantees to construct the two AP1000 units at the Vogtle plant. The cost of building the two reactors is expected to be $14 billion. Georgia Power, which owns 45.7% of Vogtle, delayed the projected in-service dates to between the fourth quarter of 2022 and first quarter of 2023 for Unit 3 and between the third and fourth quarters of 2023 for Unit 4. Environmental groups opposed to the licensing of the two new AP1000 reactors to be built at Vogtle filed a new petition in April 2011 asking the Nuclear Regulatory Commission's commission to suspend the licensing process until more is known about the evolving Fukushima I nuclear accidents. In February 2012, nine environmental groups filed a collective challenge to the certification of the Vogtle reactor design and in March they filed a challenge to the Vogtle license. In May 2013, the U.S. Court of Appeals ruled in favor of the Nuclear Regulatory Commission (NRC). In February 2012, the US Nuclear Regulatory Commission approved the two proposed reactors at the Vogtle plant. For VC Summer, a delay of at least one year and extra costs of $1.2 billion were announced in October 2014, largely due to fabrication delays. Unit 2 was then expected to be substantially complete
