Part 5: Independent System Operator and Planner Section 162: Designation etc
Section 162 empowers the Secretary of State to designate a person (likely a company) by notice as the ISOP and sets out that a notice designating a person as the ISOP must state when it comes into effect. The Secretary of State must ensure that, once the first ISOP has been designated, there is always one (and only one) person designated as the ISOP at any given time. This section also empowers the Secretary of State to revoke the ISOP designation by notice (again, stating when the notice comes into effect). The Secretary of State must publish any designation or revocation notice.
