Abstract

GOUWS, Rupert. Measurement and verification of load shifting interventions for a fridge plant system in South Africa. J. energy South. Afr. [online]. 2013, vol.24, n.1, pp.00-00. ISSN 2413-3051.

In this paper, the author presents the measurement and verification methodology used to quantify the impacts of load shifting measures that are implemented on large industrial fridge plant systems in South Africa. A summary on the operation of fridge plant systems and the data typically available for baseline development is provided. The author discusses issues surrounding baseline development and service level adjustments for the following two scenarios: 1) the electrical data is available for both the baseline and post-implementation periods; and 2) only the thermal data is available during the baseline period, but both the thermal and electrical data is available during the post-implementation period. Typical results are provided with advantages and disadvantages of both methodologies.

Keywords : fridge plants; chiller units; M&V baseline development; M&V service level adjustment; energy efficiency.
