initial decision to grant the certificate, including but not limited to, each
criterion that is outlined in this Section as a precondition for the granting
of a certificate and any changes in the energy plans for the utility and the
State.

(b) Whenever the Commission grants any certificate of public convenience
and necessity for the construction of a new electric generating facility,
the Commission shall design and establish all procedures necessary for it to

shall thereafter take all steps necessary to assure that construction is
