The construction of new nuclear reactors at Plant Vogtle in Georgia provides a real-world example to re-evaluate the costs associated with building nuclear power versus a combination of solar power and battery storage.

The Plant Vogtle expansion involved the construction of two new reactors, Units 3 and 4, which faced significant delays and cost overruns. Initially estimated to cost around $14 billion with an expected operational start in 2016, the project's expenses ballooned to over $30 billion, more than double the original estimate. This increase does not include an additional $3.68 billion paid by the original contractor, Westinghouse, to the owners after going bankrupt, which brings the total spending to more than $34 billion. The construction started in 2009, with Unit 3 reaching "initial criticality" in 2023, marking the beginning of a self-sustaining nuclear fission reaction. Unit 3 is expected to come into service in mid-2023, with Unit 4 following in late 2023 or early 2024 [1](https://www.gpb.org/news/2023/05/25/georgia-nuclear-rebirth-...)

- Nuclear (Vogtle): The total projected costs for the Vogtle expansion are nearing $35 billion for two reactors, providing a combined capacity of 2.2 GW. This translates to approximately $15.9 billion per GW.

- Solar + Megapack: As previously estimated, the capital cost for solar power is around $1 billion per GW. Adding battery storage to match the continuous output capability of nuclear plants significantly affects the total cost. Tesla Megapack costs vary, but an estimate of around $200 million for 1 GWh of storage was given. The exact cost for solar plus Megapack to achieve comparable 24/7 output capacity as nuclear would depend on the required storage duration to offset the variability of solar generation.

The Vogtle project's cost overruns and delays highlight the financial risks associated with large-scale nuclear projects. The actual cost of Vogtle significantly exceeds initial projections, emphasizing the challenge of managing complex nuclear construction projects within budget and timeline expectations. In contrast, solar and battery storage projects, such as those utilizing Tesla's Megapack, offer faster deployment times and have seen decreasing costs over time. However, to achieve a continuous power supply similar to a 1 GW nuclear plant, substantial investment in storage would be necessary, potentially narrowing the cost difference.

These insights from the Vogtle project's experience underline the importance of considering not only the upfront capital costs but also the risk of cost overruns and delays in large-scale energy projects. While nuclear power offers the advantage of continuous, low-carbon electricity generation, the financial and logistical challenges evident in the Vogtle expansion may prompt utilities and policymakers to favor the more predictable costs and scalability of renewable energy and storage solutions.

For future energy projects, this comparison underscores the necessity of rigorous project management, realistic budgeting, and the consideration of evolving energy technologies and market conditions.
