Measurement and Verification of Industrial Energy Conservation Projects

Abstract

Ontario Power Authority (OPA) is one of the key agencies to im-
plement electricity conservation programs in Ontario, Canada. OPA is
putting increasing emphasis on carrying out measurement and verifica-
tion (M&V) for electricity conservation and demand-side management
projects for all its incentive programs. This article discusses the measure-
ment and verification carried out for some of those projects. The cases are
taken from M&V reviews carried out for various industrial plants located
in Ontario. The measurement and verification was part of the Building
Owners and Managers Association (BOMA) Conservation and Demand
Management (CDM) program, which was supported by the OPA.
As per the BOMA Toronto CDM incentive program, there was in-
centive for electricity conservation and demand reduction measures. The
rigor of the M&V process required would vary depending on the electric-
ity savings. Measures with savings less then 50 kW/400,000 kWh would
fall in the basic category while measures more than 50 kW/400,000 kWh
would fall in the enhanced category. Some of the M&Vs discussed in the
article are implementation of a cooling water bypass pump in a cogenera-
tion plant, lighting retrofit and lighting controls in a brewery, and imple-
mentation of compressed air controls from a coffee packaging facility. In
many of these cases, Option A and Option B from the International Per-
formance Measurement and Verification Protocol (IPMVP) guidelines are
followed. Elements of the M&V plans are discussed. Some of the issues,
like metering methods used for determining variation of electricity for
different operating conditions, are highlighted. The benefits of the M&V
process to all the stakeholders are also discussed.
