Here is the percentage of the combined wind + Solar + Nuclear + Hydroelectric on some grids in the East & Midwest, along with their instantaneous direction of growth/decline at 5PM CST on 3/11/2022:

  ERCOT  57.3 \ Electric Reliability Council of Texas
  MISO   41.9 - Midwest Independent System Operator
  NYIS   50.6 \ New York Independent System Operator
  SPP    44.4 \ SouthWest Power Pool
  PJM    42.4 ↗ PJM Interconnection (PA, NJ, MD, OH, IN, DE & Chicago)

...and at 6PM CST:

  ERCOT  48.7 \ Electric Reliability Council of Texas
  MISO   40.7 \ Midwest Independent System Operator
  NYIS   50.1 - New York Independent System Operator
  SPP    37.5 \ SouthWest Power Pool
  PJM    41.5 - PJM Interconnection (PA, NJ, MD, OH, IN, DE & Chicago)

So you can see, that, particularly in wind-blow Texas and middle of the U.S. (SPP includes Oklahoma, Kansas and Nebraska), the penetration of renewables + Nuclear is quite dynamic.
