Constellation Energy plans to reopen the Three Mile Island nuclear plant in Pennsylvania

9/23/24 9:03AM

On Friday, Constellation Energy said that it has plans to reopen the Three Mile Island nuclear plant in Pennsylvania, the site of a nuclear meltdown that destroyed the second reactor at the power station in 1979.

The plant, which continued to operate safely for years after the accident, was eventually closed down in 2019 for economic reasons. But the conditions that led to its shutdown no longer hold, as demand for clean electricity soars thanks to growing demand for data centers. That has made boring old utilities stocks the best performers in the S&P 500 Index this year (chart), with Constellation Energy shares contributing significantly to that trend, having gained more than 120% in 2024.

But where are America’s nuclear power plants? We’ve mapped out the location of all 54, according to data from the Energy Information Administration.

Once operational, Three Mile Island would be the fifth nuclear power plant in Pennsylvania. Only Illinois, which has 6 nuclear plants, would have more. The rest are predominantly in eastern states, although the country’s largest is Palo Verde Station in Arizona, which has a total capacity of 3,937 megawatts — enough to power some 4 million homes.

For decades, America’s nuclear output plateaued, with new reactors in Georgia the first to be built from scratch in the US for more than 30 years. If demand for electricity to power the AI wave continues to boom, they won’t be the last.

On Wednesday, Google CEO Sundar Pichai said in a blog post that AI is now writing 75% of new code at the company. This is up from 50% last fall. Pichai said all code is “approved by engineers.”

Google announced new TPU 8 chips today at its annual Cloud Next event. Pichai wrote:

“We’re now shifting to truly agentic workflows. Our engineers are orchestrating fully autonomous digital task forces, firing off agents and accomplishing incredible things.”

Tesla just opened the door to 50,000 government buyers

Tesla signed a deal that lets more than 50,000 public agencies — including police departments and school districts — buy its vehicles without the usual slow bidding process, making it much easier to compete in a market long dominated by Ford and General Motors. The public sector currently represents less than 1% of Tesla’s sales.

The move doesn’t guarantee orders, but it removes a major barrier at a time when Tesla is looking for new demand to bolster its main source of revenues. Tesla’s Q1 deliveries fell short of analyst expectations and annual sales have declined for two years in a row. The public sector also represents a large pool of buyers who are beyond Elon Musk’s other companies.

How Elon Musk has shifted SpaceX’s goals ahead of its IPO

The New York Times took a close look at how Elon Musk is reshaping SpaceX’s priorities ahead of its highly anticipated, potentially record-breaking IPO — and what that could mean for the company and its investors.

As the NYT’s Ryan Mac noted in the article, “Shifting aims before an I.P.O. would be unthinkable for most corporate leaders, who tend to focus on their core businesses and try to project steadiness to potential investors.”

But Musk, who is also the ever-unpredictable CEO of Tesla, doesn’t follow typical playbooks. Here’s a quick look at how SpaceX’s goals have changed:

SpaceX seals right to buy coding startup Cursor for $60 billion

SpaceX said today that it’s “working closely together” with fast-growing coding startup Cursor “to create the world’s best coding and knowledge work AI.” The post also said SpaceX would have the right to acquire Cursor later this year or make the startup “pay $10 billion for our work together.” The New York Times, citing people familiar with the matter, previously reported that the companies had agreed to an acquisition.

The news comes as SpaceX prepares for a blockbuster IPO and doubles down on AI, with a growing — if still fully aspirational — focus on space-based data infrastructure and computing.

Last month, when SpaceX hired two senior leaders from Cursor, CEO Elon Musk noted that xAI, which SpaceX acquired earlier this year, “was not built right first time around, so is being rebuilt from the foundations up.”
