  20. (Constraint) A local limitation in the transmission capacity of the grid required to maintain grid security or power quality.
  21. (Constraint) A resource or condition that potentially limits transmission line routes, including areas that are closed by regulations (e.g. municipal airports) or where impacts would be very difficult or impossible to mitigate due to resource protection and other legal requirements.
