Appendix B: Proposed Heating and Cooling Caps


The proposed load limits are shown in the tables below. Note that for climate zones, such as Port Headland, where one of the heating or cooling load limits is between zero and five per cent of total load, separate load limits would not be applied. Note also that all climate zones are shown, even those not intended to be covered by the measure, for the information of the reader.
