CSA TS-5090:26

Description

Preface This is the first edition of CSA TS-5090, Demand impact estimation using load shapes . The purpose of this Technical Specification (referred to as “this Document” from here on) is to provide a methodology for estimating the demand impacts from electrical energy performance measures by using the peak-to-energy factor (PEF) indicator applied to load shapes. This Document is not a consensus product; that is, it is not a standard and it has not been formally approved by a CSA Technical Committee. CSA Group acknowledges that the development of this Document was made possible, in part, by the financial support of BC Hydro, British Columbia’s Ministry of Energy and Climate Solutions, Efficiency Manitoba, Fortis BC Electric, Hydro-Québec, Natural Resources Canada, and Québec’s Ministère de l’Environnement, de la Lutte contre les changements climatiques, de la Faune et des Parcs. This Document was prepared by the Development Committee on Demand Impact Estimation. Scope 1.1 General This Document defines the method, requirements, and considerations for estimating coincidence peak demand impacts from energy impact using load shape analysis and peak-to-energy factors (PEFs). It applies to residential, commercial, and industrial sectors where the load shapes can represent a) the relationship between energy and peak demand impact; or b) the time-differentiated energy savings within Canadian electrical systems. 1.2 Inclusions This Document applies to a) technology-based measures, including i) lighting; ii) heating, ventilation, and air conditioning (HVAC); iii) water heating; iv) refrigeration; v) building envelope; vi) major electric appliances; and vii) industrial end uses; b) behavioural-based measures according to CSA/ANSI C555; and c) a mix of technology and behavioural-based measures, including i) energy management improvements; and ii) building automation systems (BASs). Note: See Annex B. 1.3 Exclusions This Document does not apply to a) non-electrical energy saving measures; b) interventions intended primarily to temporarily reduce/shift loads; c) demand response programs (such as behavioural change) including i) dynamic control programs (such as connected equipment); ii) load curtailment or interruptible end uses; and iii) project-based demand estimation through measurement and verification based on IPMVP methodology; and d) customer billing demand impact estimation. Note: See Annex B. 1.4 Terminology In this Document, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the Document; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express that which is permissible within the limits of the Document. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate explanatory or informative material from the text. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
