Yiping Shao helped finalize a prediction model for Coca-Cola’s electricity use and recommended a number of energy efficiency upgrades.
Shanghai Shen-Mei Beverage and Food Co., Ltd, one of the biggest Coca-Cola bottling plant in China, enlisted EDF Climate Corps fellow Yiping Shao to finalize a model that can predict the daily total electricity consumption of the entire plan for a one-month period. Coca Cola has already installed and implemented smart metering and online monitoring systems for energy efficiency, but this was an opportunity to see deeper savings from demand-side management incentives due to the current electricity pricing reform in China. If the company could provide an estimate of their predicted electricity use prior to each purchase cycle, utility companies, looking to better plan and balance demand and supply, avoid electricity waste and increase reliability, would offer incentives if the margin of error is 2-5%.
Based in Coca-Cola’s Shanghai production plant Yiping Shao analyzed data collected from 16 of the company’s energy systems, gathered through already-installed smart metering and online monitoring systems. At this plant, monthly electricity use varies anywhere from 1.82 to 6.27 million kilowatt-hours, due to seasonal changes during the year. Shao perfected the model so that it could predict the daily electricity consumption, within the error margin, for 30 days in advance.
Shao then focused on a number of energy efficiency upgrades. He recommended an assortment of ways to improve the transformer in the electric power systems, as well as increase efficiency of the workshop lighting system through LED retrofits and smart sockets installations in electrical machines--such as freezers, drinking fountains and coffee machines--which are programmed to automatically turn off machines during times of no use.
These projects, when fully implemented, have the potential to save Coca-Cola 446,000 kWh of annual electricity savings, over a hundred thousand dollars of cost savings and 125 metric tons of CO2 emissions reductions.
