Extent: E+W+S

In this Part of this Schedule—
“additional costs” means any costs incurred by the licensee in carrying out decommissioning of the Johnston Assets which would not have been incurred had such decommissioning works been carried out prior to commencement of the undertaker’s works, and relating to any of the following—
