Measurement and Verification of Industrial Energy Conservation Projects
Ontario Power Authority (OPA) is one of the key agencies to implement electricity conservation programs in Ontario, Canada. OPA is putting increasing emphasis on carrying out measurement and verification (M&V) for electricity conservation and demand-side management projects for all its incentive programs. This article discusses the measurement 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 incentive for electricity conservation and demand reduction measures. The rigor of the M&V process required would vary depending on the electricity 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 cogeneration plant, lighting retrofit and lighting controls in a brewery, and implementation of compressed air controls from a coffee packaging facility. In many of these cases, Option A and Option B from the International Performance 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.
