The licensee shall have the right at any time, on giving to the Board prior notice in writing expiring at the end of any year of account, to purchase from the Board at the Grid Tariff the whole of the electricity supplied to him by the Board thereafter:-

Provided that the Board in those circumstances may make it a condition that the licensee shall, until the date on which the scheduled effective capacity of the station becomes nil, pay to the Board in respect of each month in addition to the Grid Tariff one-twelfth of such proportion as the Board may fix of the annual charges by way of interest and depreciation which would have been payable to the Board in respect of the year of account had the said notice not been given:-

Provided further that in assessing the scheduled effective capacity for the purposes of the first proviso all units of plant or works which may have been under this Schedule declared or deemed to be surplus to the requirements of the licensee at the date of expiration of the said notice and all additional units of plant or works shall after that date always be deemed to be surplus to the requirements of the licensee:-

Provided further that after the expiration of the said notice the licensee shall not be entitled any time to purchase electricity from the Board at the price ascertained under Para. XIII.
