Yes, it's actually pretty common. See comparisons across generating technologies in "An international comparative assessment of construction cost overruns for electricity infrastructure" [1].
Here's what the researchers found for solar (section 3.4):
Thirty-nine solar PV and CSP power plants, representing 2374 MW of installed capacity and $16.5 billion worth of investment, were analyzed. (These are utility-scale infrastructure projects, thus they do not include the familiar rooftop solar collectors on buildings or residential configurations.) These projects as a class actually came in $4.2 million less than budgeted, or $200,000 less than expected per project. These solar systems had the lowest
average cost escalation per reference class (1.3 percent), the least time overruns (an average of 2 months ahead of schedule), and the lowest standard deviation for amount of overruns and time overruns. They also had the largest total amount of cost underruns, with the entire class of projects costing $163.9 million less than budgeted, though some of this may be explained by dramatic reductions in cost over the past 4 years. As Table 5 indicates, only 3 facilities had overruns greater than $50 million and only 3 facilities had cost overruns greater than 30%, all of which were CSP facilities rather than large-scale solar PV apparatuses.
Here are a few solar projects that outperformed in recent years:
O'Brien solar farm in Wisconsin, completed in 2021 on time and under budget:
1) None of these are grid scale.
2) All of them are heavily subsidized.
The closest I see in that list is Mount Signal 3, which comes in at about 1/3 the capacity of a typical grid-scale generating station (1/6 if you account for the fact that it's producing zero power half the time, on average). It also chews up nearly 2,000 acres of land.
Hillston is 120 megawatts. Sun Streams 2 is 200 megawatts. Mount Signal 3 is 328 megawatts. The coal fired generating plants that retired in the US in the past decade were often smaller than that.
The table above shows that the coal generators that retired between 2009 and 2011 had an average size of 59 megawatts (MW). By contrast, the average size of a coal-fired plant planned for retirement between 2012 and 2015 is 154 MW, more than twice the average size of the units retired during the 2009-2011 period.
In 2022, coal fired generators had a capacity factor of ~48% in the United States:
As a rough guide you can estimate that an American solar farm will generate about as much electricity annually as an American coal plant with half the nameplate capacity. Mount Signal 3 would roughly match a 164 megawatt coal fired generator for annual generation.
We were comparing nuclear and solar, not coal and solar.
164 megawatts (328 / 2, to account for the fact that solar plants are offline a minimum of half the time) is not anywhere in the same league as nuclear power plant, which are typically in the 2-3 gigawatt range, with modern large-scale plants producing 6-8 gigawatts.
The Mount Signal 3 plant also used up 2,000 acres (800 hectares of Imperial Valley farm land.
Which grid-scale solar projects have gone into production on schedule and under budget? Are there any?
