> “On their face, they’re less than a third the price of building a new coal or natural gas power plant,” Ramez Naam, an energy expert and lecturer at Singularity University, told Earther in an email. “In fact, building these plants is cheaper than just operating an existing coal or natural gas plant.”

> There’s a 30 percent federal investment tax credit for solar projects that helps drive down the cost of this and other solar projects. But Naam said even if you take away that credit, “these bids, un-subsidized, are still cheaper than any new coal or gas plants, and possibly cheaper than operating existing plants.”

I'm assuming that's without factoring in the health cost externalities.

Yes, this is solely for cost of power. The healthcare savings and quality of life improvements are an additional bonus on top of very cheap power.

Does anyone have data on typical wholesale power costs?

Various data here: https://www.eia.gov/electricity/wholesale/

From my brief browsing, $23.76 is <70% of the average $/MWh price across the available data.

that is about $2 cents on kwh! Sounds about right for wholesale price.

This is truly good news, but is it really worth calling out that a record was broken when it's been trending down regularly over time?

Key milestone awareness is important. The more people who know the raw economics, the better choices that can be made.

The record being broken is just the headline of the article. The body is about the trend. The first sentence makes that perfectly clear.
