5.1 The parties agree that it is important to maintain an appropriate balance between (i) on the one hand, ensuring the efficient use of Energy and minimising the level of emissions of greenhouse gases and other noxious substances caused by the use of Energy and (ii) on the other hand, minimising the monetary cost of Energy usage. There are set out in Section 7 of Part 8 of the Schedule110 (Thermal and energy efficiency testing procedure) the agreed proportions for usage of different types of Energy. In managing the usage of Energy at the Facilities Project Co shall wherever practicable ensure that these agreed proportions are followed.
5.2 To the extent that the proportions of different types of Energy actually consumed at the Facilities differ by more than 1% from the agreed proportions referred to in paragraph 5.1 (Usage of Different Types of Energy) above any resultant increase in the cost of purchasing Energy and/or Allowances shall be for Project Co's account and shall take effect by way of an amendment to the calculation of Average Unit Cost to reflect proportions of Energy not more than 1% different from those agreed.
5.3 Paragraph 5.2 (Usage of Different Types of Energy) above shall not apply to the extent that a change in the proportions of Energy actually consumed results from a Qualifying Variation, [or as a result of the factors listed in paragraph [ ] of the Schedule (Joint Operating Protocol)]111 or from an increase or decrease from time to time in the Board's requirements for usage of a particular type of energy, or has been subject to prior agreement by the Board's Representative, or are as a result of an interrupted supply of utility from a utility provider.
