“20. Any hotel which consumes in excess of 3,200,000 kWh in a year, is a large hotel. Clearly, until it has exceeded that figure, it is not possible to say that it has done or will do so but it must, at that point, be a large hotel because it has consumed 3,200,000 kWh or more per annum. It cannot be read as a future right earned by past performance. The definition is clear and does not allow such an application. Once it consumes 3,200,000 kWh in a year, it is a large hotel for the year in which that was the consumption. As the Regulations refer to a maximum charge for electricity supplies to premises of that description, it cannot be charged above that rate for electricity consumed in the year during which it was a large hotel. 21. Nowhere have I been shown any provision in the relevant law for a different rate during the time the threshold is being reached. Once the consumption has crossed the threshold of the annual consumption, the hotel is in that category and is shown, by its consumption, to have been for the year preceding its crossing of the threshold.”
“11. It is common ground that that expression establishes a 12 month qualifying period, but that is all that it is. It is not a billing period. A hotel becomes a large hotel at the point when it passes the threshold during any given period of 12 months, but that does not constitute it a large hotel retrospectively for the whole of that period. It is not a large hotel at any point until it reaches the threshold, and to hold otherwise is to strain at the literal meaning of the definition. 12. On the other hand, it seems to us that once the threshold is reached in any twelve month period, irrespective at what point in the billing cycle, PPC is thereafter obliged to charge for each subsequent unit at the discounted rate. It cannot wait until the next billing period to apply that rate.”
