Facing possible electricity shortages, Gov. Gavin Newsom said the Diablo Canyon Power Plant might continue operating beyond its planned closing.
Even Gavin Newsom who is a psycho Greenie (presumably out of political expediency and not any real love for the position) has acknowledged that it would be a good thing to keep the Diablo Canyon nuclear power plants up and running.  They supply not quite 10% of California's electricity and work at night or when there is no wind.  Plus they are there already.  One of the units operating license will expire next year.  The other will go out in 2025.  The governor and the legislature have moved to extend the operation another ten to twenty years.  Both the NRC and PG&E say the plants will be safe to operate for that time.

However the Friends of the Earth isn't having it and are suing in federal court to shut them both down.  Back in 2016 Governor Jerry Brown, the state legislature and various regulatory agencies agreed to wind down Diablo Canyon.  FOTE is describing this as a legally binding contract.  That is apparently not necessarily the case.  PG&E points out that they are a regulated utility and will follow state policy whichever way it goes.  

Even the Biden administration has sort-of acknowledged that keeping existing power plants up and running might be a good thing and has jumped in to the tune of $6 billion.  It is believed that it will cost $1.4 billion to keep Diablo Canyon up and running beyond 2025.  

The FOTE lawsuit goes so far as to name various state labor unions in it's lawsuit as they were named in the original lawsuit back in 2016.
