# The Greenhouse Gas Emissions Trading Scheme Order 2020, Paragraph 19D: Capacity increases: net change in installed capacity at installation since reference date


(1) The net change in installed capacity at the installation since the reference date must be calculated as follows.
Step 1
Calculate the following for each relevant sub-installation—
the net change in installed capacity at the relevant sub-installation since the reference date x the benchmark for the sub-installation.
Step 2
Add up all calculations done under Step 1.
The net change in installed capacity at the installation since the reference date is the result of Step 2.
(2) For the purposes of sub-paragraph (1)—
(a) the net change in installed capacity at a relevant sub-installation must be determined by taking into account only capacity increases and capacity decreases (other than capacity decreases that are temporary) that relate to the sub-installation since the reference date;
(b) where capacity decreases exceed capacity increases at a sub-installation, the net change in installed capacity must be a negative value;
(c) in calculating the net change in installed capacity at a district heating sub-installation or a heat benchmark sub-installation of an installation that consumes or exports measurable heat produced outside the installation, any capacity increase or capacity decrease that relates to the sub-installation must not be taken into account unless it is solely associated with measurable heat produced at the installation.
(3) In this paragraph, “relevant sub-installation” means—
(a) the sub-installation to which the capacity increase relates;
(b) any other sub-installation to which a capacity decrease at the installation since the reference date relates.
