The Penetration Problem. Part II: Will the Inflation Reduction Act Cause a Blackout?

The “green” provisions of the poorly named Inflation Reduction Act are sweeping and it appears they may do more harm than good. The philosophy behind the inflation Reduction Act seems to reflect the belief that if you can get the ball rolling, adding additional wind and solar will get easier. However, as Part 1 discussed, the compounding problems associated with increasing the penetration level of wind and solar generation are extreme.
Replacing conventional synchronous generating resources, which have been the foundation of the power system, with asynchronous intermittent resources will degrade the reliability of the grid and contribute to blackout risk. The power system is the largest, most complicated wonderful machine ever made. At any given time, it must deal with multiple problems and remain stable. No resources are perfect; in a large system you will regularly find numerous problems occurring across the system. Generally, a power system can handle multiple problems and continue to provide reliable service. However, when a system lacks supportive generation sources, it becomes much more likely it will not be able function reliably when problems occur.
Just as a pile of dry wood and flammable material can be sparked from many potential sources, or a very unhealthy person could succumb to many different threats, a weakened power system is more vulnerable to many conditions than a robust one. In this post I discussed responsibility for the Texas winter blackout. Many things went wrong that day in Texas. But often many things do go wrong – the real problem was that the Texas market did not provide incentives for standby resources. In Texas there were not enough committed resources to provide for the system load levels and potential contingencies. Texas relied on an energy market designed to favor wind and solar resources and it failed them. However, many analyses of the Texas blackout focused on the proximate conditions (problems of the sort that are common) ignoring or denying the major underlying problem.
