Recognised Energy Savings Activities (RESAs) are specific activities implemented by an Energy Saver that increase the efficiency of electricity consumption or reduce electricity consumption, without negative effects on production or service levels, by:
- modifying End-User Equipment or usage of End-User Equipment (including installing additional components);
- replacing End-User Equipment with other End-User Equipment that consume less electricity;
- installing New End-User Equipment that consumes less electricity than other End-User Equipment of the same type, function, output or service; or
- removing End-User Equipment that results in reduced electricity consumption, where there is no negative effect on production or service levels.
The ESS Rule recognises three different methods for claiming the energy savings from RESAs. Applicants should carefully consider the most appropriate methodology to suit the circumstances of their particular project, as below:
- the Project Impact Assessment Method (PIAM) is a calculation method best suited to discrete RESAs where the overall reduction in electricity use is a small proportion of total site use.
- the Metered Baseline Method provides calculation methodologies for use where the RESA(s) materially reduce the electricity consumption of a whole site, or discrete part of a site, and the energy savings can be determined by reference to a site baseline. This method can be used for buildings with a NABERS rating.
- the Deemed Energy Savings Method provides calculation methodologies for use where the RESA(s) involve installing or replacing a range of common End User Equipment types. Under these methodologies, the energy savings are deemed (i.e. the lifetime savings are created upfront).
In some cases, the Scheme Administrator may recommend a different approach to that proposed by the applicant. This would only occur after a period of assessment and consultation with the applicant.
Note: Activities performed to fulfil a statutory obligation and or purchase of electricity under “Green Power” accredited or similar schemes that are eligible to create certificates or RECs at the point of generation, are excluded from being recognised as energy savings under the scheme.
It is important to note that certain things are excluded from being recognised as energy savings under the scheme. This includes any activities performed to fulfil a statutory obligation and purchase of electricity under “Green Power” accredited or similar schemes that are eligible to create certificates or RECs at the point of generation.
