“Using sulphur hexafluoride in electrical switchgear

“44A Application of regulations 44B and 44C

• A person must comply with regulations 44B and 44C if the person, in any year, is a participant under section 54(1)(a) of the Act in respect of the activity in subpart 2 of Part 4 of Schedule 3 of the Act of operating electrical switchgear that uses sulphur hexafluoride.

“44B Collection and recording of information for calculating emissions from use of sulphur hexafluoride in pre-charged equipment

• “(1) The person must collect and record information in relation to electrical switchgear that uses sulphur hexafluoride and that is operated by the person in the year.

  “(2) The information is—

  • “(a) the total amount (in kilograms) of sulphur hexafluoride that is added into the electrical switchgear in the year; and

  • “(b) the capacity for sulphur hexafluoride (in kilograms) of the electrical switchgear; and

  • “(c) in relation to electrical switchgear that is installed in the year, the total amount (in kilograms) of sulphur hexafluoride in the electrical switchgear immediately before it is installed; and

  • “(d) in relation to electrical switchgear that ceases to be operated in the year, the total amount of sulphur hexafluoride (in kilograms) in the electrical switchgear immediately after it ceases to be operated.

  “(3) If the person is required to collect and record information under this regulation in the year beginning on 1 January 2013 and ending with the close of 31 December 2013, the information must relate to that period.

“44C Method of calculating emissions from use of sulphur hexafluoride

• Emissions in relation to an item of electrical switchgear that uses sulphur hexafluoride and is operated by the person in the year must be calculated in accordance with the following formula:

  TE =		GWP × [(A – (Σ (B – C)) + (Σ (D – E))]
  		1000

  where—

  A

  is the total number of kilograms of sulphur hexafluoride that is added into the electrical switchgear after it is installed in the year as recorded under regulation 44B

  B

  is,—

  • (a)  if the item of electrical switchgear was installed in the year, the capacity of the item; or

  • (b) otherwise, zero

  C

  is,—

  • (a) if the item of electrical switchgear was installed in the year, the total number of kilograms of sulphur hexafluoride in the item immediately before it is installed; or

  • (b) otherwise, zero

  D

  is,—

  • (a) if the item of electrical switchgear ceases to be operated in the year, the capacity of the item; or

  • (b) otherwise, zero

  E

  is,—

  • (a) if the item of electrical switchgear ceases to be operated by the person in the year, the total number of kilograms of sulphur hexafluoride in the item immediately after it ceases to be operated; or

  • (b) otherwise, zero

  GWP

  is the GWP figure for sulphur hexafluoride in table 1 of Schedule 2A

  TE

  is the total emissions in tonnes for operating electrical switchgear.
