Everything is caused by regulation in one way or another. But your statements don't represent the reality of the report that was released:

Key notes:
"... overall, the North American bulk power system (BPS) remains highly reliable and resilient. However, extreme weather events continue to pose the greatest risk to its reliability and stability"
"Today’s BPS transmission system is continuing to show improvements in reliability and resilience, despite more common and extreme weather trends. However, higher overall outage rates for coal and gas generation, as well as some utility-scale solar generation not operating as necessary for reliability, indicate that there is still significant work to be accomplished"
"In 2022, conventional generation experienced its highest level of unavailability (8.5%) overall since NERC began gathering GADS data in 2013 as measured by the weighted equivalent forced outage rate. Figure 3 shows consistently increasing outage rates for coal over the observed five years, correlating with higher numbers of startups and maintenance outages."
Yes, there are issues to contend with when implementing new power sources. But those issues are nothing compared to the lack of investment in infrastructure more generally.
