[T]he report's executive summary certainly gets to the heart of their findings.

"The rhetoric from small modular reactor (SMR) advocates is loud and persistent: This time will be different because the cost overruns and schedule delays that have plagued large reactor construction projects will not be repeated with the new designs," says the report. "But the few SMRs that have been built (or have been started) paint a different picture – one that looks startlingly similar to the past. Significant construction delays are still the norm and costs have continued to climb."

It's interesting watching how the 30minute electricy price has shifted patterns in the UK. 3-4 years ago there was no doubt that the cheapest time was 1am - 4am. These days the overnight dip isn't anywhere near as significant as it was, and it's now equally likely for 1pm-4pm to be the cheapest time of day.

All I can assume is that so many have moved usage to overnight due to "time of use" tariffs that now the demand curve has evened out a bit, and now the extra supply from solar during the day pushes the afternoon price down.
