(2) Subsection (1) does not apply if this determination specifies otherwise.
Part 2—Aggregated small energy users projects
9 Aggregated small energy users projects
(1) For paragraph 106(1)(a) of the Act, this determination applies to an offsets project that satisfies the following:
(a) the project involves targeting treatment to small energy users within a population;
(b) the project involves using a control group within the population to test whether, and by how much, emissions of greenhouse gas have been reduced in a treatment group within the population;
(c) each good or service in the treatment could reasonably be expected to result in eligible carbon abatement.
Note: Treatment may involve directly providing goods or services, or may involve promoting or providing information to encourage small energy users to take up particular goods or services: see section 7. The treatment offered may vary between sites in a population.
(2) A project covered by subsection (1) is an aggregated small energy users project.
Part 3—Project requirements
Division 1—Operation of this Part
10 Operation of this Part
For paragraph 106(1)(b) of the Act, this Part sets out requirements that must be met for an aggregated small energy users project to be an eligible offsets project.
Division 2—General requirements
11 Information to be included in application for declaration
The application under section 22 of the Act in relation to the project must include a description of:
(a) the goods or services to be offered as treatment under the project; and
(b) the sites or types of sites that are or will be included in the populations in the project.
12 Legal right to access and use data about energy consumption
If the project proponent for the project uses data, about energy consumption for a site in a population in the project, to calculate the carbon dioxide equivalent net abatement amount for the project in accordance with Part 4, the project proponent must have a legal right to:
(a) access the data; and
(b) use the data for that purpose.
Note: If there is more than one project proponent for a project, it is not necessary for each project proponent to have a legal right to access and use the data. A project proponent is required to have that legal right only if the project proponent will access and use the data to calculate the carbon dioxide equivalent net abatement amount for the project.
13 Project proponent not to be actively involved in decision‑making
(1) The project proponent for the project must not be in a position to make decisions about the following:
(a) how much energy is consumed at a site in a population in the project;
(b) the installation, replacement or removal of energy‑consuming equipment at the site;
(c) changes to the shell of a building at the site.
(2) However, subsection (1) does not apply to:
(a) the targeting of treatment to the site; or
(b) activities relating to supplying energy to the site.
Example: Disconnecting an energy service because of non‑payment.
Division 3—Making choices for the project
Subdivision A—Populations and selecting sites
14 Choosing populations
(1) Before the start of the first measurement period for any population in the project, the project proponent for the project must choose one or more populations for the project.
Note: A project may include more than one population.
(2) All of the sites in a particular population must be either:
(a) identified sites; or
(b) sites of a particular type.
Note 1: Identified sites may be identified by reference to their address.
Note 2: An example of a type of site is sites that are household customers of a particular retailer in a particular State. A population may consist of more than one type of site.
(3) If the project proponent chooses a population that does not consist of a set of identified sites, it must be clear, at all relevant times between when the population is chosen and the end of the crediting period for the project, whether a particular site is or is not part of the population.
(4) Subject to section 16, the population must remain the same between when the population is chosen and the end of the crediting period for the project.
Note: If the population consists of a set of sites of a particular type, the sites within the population may change as sites become that type of site or cease to be that type of site.
(5) The project proponent may add a population to the project after the project has started, but the population must be chosen before the first measurement period for that population starts.
(6) Once a population is chosen, other choices may be made under this Division that relate to the population.
15 Selecting sites for a control group or treatment group
(1) Before the start of the first measurement period for a population in the project, the project proponent for the project must select sites in the population for the control group and the treatment group using a random selection method (the initial selection).
Note 1: The control group and treatment group may include a different number of sites.
Note 2: Using a random selection method, sites may be selected for the treatment group, and all remaining sites are selected by default for the control group, or vice versa. Alternatively, sites may be selected for the treatment group, other sites may be selected for the control group, and all remaining sites are not selected for either group.
(2) If the project proponent adds sites (the subsequent selection) to the control or treatment group after the initial selection for the population;
(a) each of those sites in the subsequent selection must be:
(i) added at the start of a measurement period for the population; and
(ii) selected using a random selection method; and
(b) the ratio of the number of sites selected in the subsequent selection for the control group relative to the number of sites selected in the subsequent selection for the treatment group must be the same as the ratio for the initial selection.
(3) An accredited statistician must certify that the selecting of sites was done in accordance with this section.
(4) Subject to section 16, if a site is selected for the control group or treatment group, the site must be retained in that group until the end of the crediting period for of the project.
16 Sites affected by attrition
(1) If a site in a population in the project is affected by attrition during the crediting period for the project, the site must be excluded from the population on and after the day the site becomes affected by attrition, until the end of the crediting period for the project.
Note: For the purposes of Part 4, sites may be excluded from the beginning of a measurement period: see section 35.
(2) A site is affected by attrition if:
(a) the consumption of natural gas, or electricity from an electricity grid, (or both) by a small energy user at the site has been measured as part of the project through one or more metered accounts relating to that user, and one or more of those metered accounts is terminated, resulting in data about energy consumption at the site ceasing to be available for at least one energy source chosen for the site under section 20; or
(b) for a reason beyond the control of the project proponent for the project:
(i) the occupant of the site makes a written request to the project proponent that data about the occupant’s energy consumption not be used for the purpose of calculating the carbon dioxide equivalent net abatement amount for the project; or
(ii) the project proponent otherwise ceases to have a legal right to access and use data about energy consumption from an energy source chosen for the site under section 20; or
(c) for a site in a population that consists of sites of a particular type—the site ceases to be a type of site in the population.
Note 1: Reasons for terminating a metered account include switching to a different energy retailer, disconnecting the service, or relocating to a different site.
Note 2: If a site ceases to be one type of site in the population, but is a site of a different type in the population, the site is not affected by attrition.
Subdivision B—Measurement periods and pre‑treatment periods
17 Choosing the start day for the first measurement period
(1) Before the initial selection for a population in the project, the project proponent for the project must choose a start day for the first measurement period for the population.
(2) The start day for the first measurement period must be a day that occurs on or after the start of the crediting period for the project.
Note: The start day for the second or subsequent measurement period is immediately after the end of the previous measurement period for the population: see the definition of measurement period in section 5.
18 Choosing start day and end day for pre‑treatment periods
(1) This section applies if the project proponent for the project chooses to use sub‑method 2 or 3 for the purposes of working out abatement for a population in the project under Part 4.
For measurement periods of 1 year
(2) Before the initial selection for a population in the project, the project proponent must choose the start day and end day for the pre‑treatment period that will be used in relation to every measurement period for the population that is 1 year.
(3) For sub‑method 2, the pre‑treatment period chosen under subsection (2) must be 12 months.
For measurement periods longer than 1 year
(4) For sub‑method 2, if the last measurement period for the population in the crediting period for the project will be longer than 1 year:
(a) before the initial selection for the population, the project proponent must choose the start day and end day for the pre‑treatment period that will be used in relation to that measurement period; and
(b) the pre‑treatment period must:
(i) cover the same dates of a year as are covered by the measurement period in a later year; and
(ii) include the start day of the pre‑treatment period chosen under subsection (2) for the measurement periods that are 1 year.
Example: For subparagraph (b)(i), if the measurement period starts on 6 January 2016 and ends on 17 February 2017, the pre‑treatment period must start on 6 January in a year and end on 17 February the next year.
(5) For sub‑method 3, if the last measurement period for the population in the crediting period for the project will be longer than 1 year, the project proponent:
(a) must use the pre‑treatment period, chosen under subsection (2) for the population, for the measurement period; or
(b) before the initial selection for the population, must choose the start day and end day for the pre‑treatment period that will be used in relation to that measurement period.
Subdivision C—Sub‑methods and explanatory variables
19 Choosing a sub‑method and explanatory variables
Before the initial selection for a population in the project, the project proponent for the project must choose:
(a) the sub‑method that will be used to work out the abatement for the population for the measurement periods for the project; and
(b) if sub‑method 3 is chosen for the population—the explanatory variables (if any) that will be used for the factor OtherVariabless,k in section 58 for the population for the measurement periods for the project.
Subdivision D—Sources of energy
20 Choosing energy sources
(1) By the time of the initial selection for a population in the project, the project proponent for the project must have chosen, for each site that is in the population at that time, whether to measure the consumption of natural gas, or electricity from an electricity grid, (or both) at the site.
(2) By the time of a subsequent selection for a population in the project, the project proponent for the project must have chosen, for each site in the population at that time for which an energy source has not been chosen, whether to measure the consumption of natural gas, or electricity from an electricity grid, (or both) at the site.
(3) The choice under subsection (1) or (2) must not be based on whether the site will be selected for the control group or treatment group in the population.
Division 4—Treatment and activities of the project proponent
Subdivision A—Dealing with control group and treatment group differently
21 Dealing with control group and treatment group differently
(1) The project proponent for the project must not deal with sites in the control group differently from sites in the treatment group if the differential dealing is likely to have more than a minor or trivial effect on the carbon dioxide equivalent net abatement amount calculated for the project.
(2) However, subsection (1) does not apply to:
(a) the targeting of treatment to sites; and
(b) the requirements set out in Subdivision B.
22 Offering goods or services to cause higher energy consumption at sites in control group
The project proponent for the project must not offer, or cause to be offered, goods or services to sites in the control group in a population in the project if:
(a) offering the goods or services is likely to result in higher consumption of natural gas, or electricity from an electricity grid, at sites in the control group than would otherwise have occurred; and
(b) the goods or services are offered:
(i) to a greater proportion of the control group than the treatment group in the population; or
(ii) in equal proportion to the control group and the treatment group in the population, but the basis for choosing which sites receive the offer is different for the control group than the treatment group.
Example: Promoting to sites in the control group the installation of energy‑consuming equipment that may increase consumption of natural gas, or electricity from an electricity grid, at those sites.
23 Offering goods or services to control group that would usually be offered
The project proponent for the project must not withhold, or cause to be withheld, goods or services from sites in the control group in a population in the project if:
(a) the goods or services relate to supplying energy; and
(b) the goods or services would usually be provided by the project proponent as part of usual business practices of supplying energy; and
(b) the goods or services are withheld:
(i) from a greater proportion of the control group than the treatment group in the population; or
(ii) in equal proportion to the control group and the treatment group in the population, but the basis for choosing from which sites the goods or services are withheld is different for the control group than the treatment group.
Example: Not providing a leaflet on energy efficiency that the project proponent usually provides as part of usual business practices.
24 Promoting government programs disproportionately to treatment group
(1) The project proponent for the project must not:
(a) offer goods or services that are funded or supported under:
(i) a government program or scheme; or
(ii) another eligible offsets project; or
(b) advise or facilitate the uptake of goods or services that are funded or supported under a government program or scheme or another eligible offsets project; or
(c) cause the offer, advice or facilitation to be given;
in the circumstances mentioned in subsection (2).
(2) The circumstances are:
(a) the offer, advice or facilitation is given to:
(i) a greater proportion of the treatment group in a population in the project than the control group in the population; or
(ii) an equal proportion of the treatment group in a population in the project and the control group in the population, but the basis for choosing which sites receive the offer, advice or facilitation is different for the control group than the treatment group; and
(b) the goods or services mentioned in paragraph (1)(a) are likely to result in lower consumption of natural gas, or electricity from an electricity grid, at sites in the treatment group than would otherwise have occurred.
(3) In this section:
government program or scheme means:
(a) a government program or scheme, specified in legislative rules (if any) made under subparagraph 27(4A)(c)(ii) of the Act, under which an offsets project must not receive funding or support for activities undertaken as part of that project; or
(b) a government program or scheme that funds or supports an activity that, under legislative rules (if any) made for subparagraph 27(4A)(c)(ii) of the Act, must not be included in an eligible offsets project.
25 Measuring energy consumption
(1) The project proponent for the project must not change, or cause to be changed:
(a) the method under section 71 or 72 by which energy consumption is monitored at sites in the control group or treatment group; or
(b) the metering arrangements for monitoring energy consumption at a site;
if subsection (2) applies.
(2) This subsection applies if:
(a) the change mentioned in subsection (1) is likely to:
(i) result in higher measured energy consumption at sites in the control group than would otherwise have occurred; or
(ii) result in lower measured energy consumption at sites in the treatment group than would otherwise have occurred; and
(b) the change occurs at:
(i) a greater proportion of sites in the control group than sites in the treatment group, or vice versa; or
(ii) an equal proportion of sites in the control group and treatment group, but the basis for choosing the sites at which the change occurs is different for the control group than the treatment group.
(3) However, the treatment under the project may include replacing an existing meter at a site with a different kind of meter.
Subdivision B—Other requirements
26 Occupants of sites in control group not to be informed of their role

Division 6—Calculation of abatement from regression modelling—sub‑method 3
Subdivision A—Summary
55 Summary
Using sub‑method 3, calculating abatement for a population in a measurement period involves estimating the effect of treatment on mean daily emissions of greenhouse gas at sites in the population, using a linear regression model that relates mean daily emissions at sites during the measurement period to a number of independent variables. Variables used in the regression analysis include the mean daily emissions at sites in the relevant pre‑treatment period, and whether the site is in the treatment group in the population. The regression is weighted by the number of days in the measurement period for which there is data, about measured energy consumption at the site, that is used for the purposes of this Part.
If the estimated treatment effect is statistically significant, abatement for the population is calculated by multiplying the negative of the estimated treatment effect by the number of days for which there is data about measured energy consumption at sites in the treatment group in the population.

(a) requirements to monitor an aggregated small energy users project that is an eligible offsets project (see Subdivision B); and
(b) certain consequences if the project proponent for the project fails to monitor the project as required (see Subdivision C).
Subdivision B—Monitoring requirements
70 Monitoring energy consumption
(1) The energy consumption from the energy source or sources chosen for a site in a population in the project under section 20 must be monitored for the site for all time periods in the crediting period for the project for which the site is part of the control group or treatment group in the population.
(2) However, there is no requirement to monitor energy consumption:
(a) at a site from the time the site is affected by attrition; or
(b) for a measurement period at sites in a population in the project if abatement for the population will not be calculated for that measurement period under Part 4.
71 Monitoring energy consumption using billing data
(1) This section applies if the project proponent for the project monitors energy consumption at a site in a population in the project using billing data.
Note: See section 34 in relation to pro‑rataing data about energy consumption.
(2) The project proponent must monitor the site’s energy consumption using billing data that is derived from data that is collected in accordance with:
(a) the National Energy Retail Rules made under the National Energy Retail Law, as that law applies in the jurisdiction where the site is located; and
(b) the law regulating the supply of the energy to retail customers in that jurisdiction.
72 Monitoring energy consumption other than using billing data
(1) This section applies if the project proponent for the project monitors energy consumption at a site in a population in the project using a method other than using billing data.
Note: See section 34 in relation to pro‑rataing data about energy consumption.
(2) The project proponent must monitor the site’s energy consumption that:
(a) is either:
(i) electricity consumed, from an electricity grid, at the site, measured in kilowatt hours; or
(ii) natural gas consumption at the site, measured in gigajoules; and
(b) meets the requirements of subsection (3) or (4).
Note: The project proponent does not itself need to measure the energy consumption but may access data from another party, such as a metering company, that measures the energy consumption.
(3) Energy consumption meets this requirement if it is measured and estimated in accordance with:
(a) the National Energy Retail Rules made under the National Energy Retail Law, as that law applies in the jurisdiction where the site is located; and
(b) the law regulating the supply of the energy to retail customers in that jurisdiction.
(4) Energy consumption meets this requirement if:
(a) it is measured in accordance with a metering arrangement that complies with the relevant requirements of the National Measurement Institute, including requirements in relation to meters; and
(b) the installing and reading of meters, and the measuring, estimating and checking of the energy consumption, was done:
(i) without bias as to whether the site is in the control group or the treatment group in a population; and
(ii) by a person who had no knowledge of whether the site is in that control group or treatment group.
73 Monitoring explanatory variables for sub‑method 3
(1) This section applies if the project proponent for the project will use sub‑method 3 to calculate the abatement for a population in the project under Part 4.
(2) The project proponent must monitor the explanatory variables (if any) the project proponent has chosen for the population for the purposes of using that sub‑method, using data collected by the project proponent or by a third party.
(3) If the project proponent monitors the explanatory variable using data collected by the project proponent, the explanatory variable must be monitored as follows:
(a) the variable must be measured accurately; and
(b) the variable must be measured in accordance with industry practice (if any); and
(c) the variable must be measured for each site in the population for all time periods in the crediting period for the project for which the site is part of the control group or treatment group in the population; and
(d) if the variable is monitored from a place other than the site for which the variable is being monitored—the measurements for the variable must closely reflect the measurements that would be expected if the variable were monitored at the site.
Example: If the variable relates to weather, the place at which the variable is monitored must experience similar weather conditions to the site for which the variable is being monitored.
(4) If the project proponent monitors the explanatory variable using data collected by a third party, the project proponent must use data about the variable:
(a) that is collected accurately and in accordance with industry practice (if any); and
(b) for each site in the population for all time periods in the crediting period for the project for which the site is part of the control group or treatment group in the population; and
(c) if the data was collected at a place other than the site for which the variable is being monitored—that reflects, as closely as possible, the data that would be expected if the data were collected at the site.
(5) However, there is no requirement to monitor the explanatory variable for a measurement period at sites in a population in the project if abatement for the population will not be calculated for that measurement period under Part 4.
Subdivision C—Consequences of failing to monitor the project as required
74 Consequences of not monitoring explanatory variable as required
(1) This section applies if, during a particular period (the non‑monitored period) in a reporting period, the project proponent for an aggregated small energy users project fails to monitor an explanatory variable for a site in a population as required by the monitoring requirements.
(2) The value of the explanatory variable for the purpose of working out the carbon dioxide equivalent net abatement amount for the reporting period is to be determined for the site for the non‑monitored period in accordance with the following:
(a) industry practice (if any);
(b) any relevant historical values for that variable for the site;
(c) any other data that relates to the explanatory variable;
(d) any other matter the project proponent considers relevant.
(3) To avoid doubt, this section does not prevent the Regulator from taking action under the Act, or regulations or rules made under the Act, in relation to the project proponent’s failure to monitor an explanatory variable as required by the monitoring requirements.
Note: Examples of action that may be taken include the following:
(a) if the failure constitutes a breach of a civil penalty provision in section 194 of the Act (which deals with project monitoring requirements), the Regulator may apply for a civil penalty order in respect of the breach;
(b) if false or misleading information was given to the Regulator in relation to the failure, the Regulator may revoke the project’s section 27 declaration under regulations or rules made for the purposes of section 38 of the Act;
(c) if the giving of false or misleading information in relation to the failure led to the issue of Australian carbon credit units, the Regulator may require all or some of those units to be relinquished under section 88 of the Act.
