Žito company

Company Profile: Production of bakery, confectionary and milled products, frozen foods, candy, chewing gum, chocolate, biscuit pastry, pasta, spices, tea, and rice.
Project: Information system for energy management

 

KEY FIGURES:

  • Consumption of resources: electricity
  • Facilities: number of buildings 12
  • Data sourses: 40
  • Primary energy consumers: Primary electricity consumers: cooling and refrigeration technologies, HVAC, lightning

 

CHALLENGES:

The primary purpose of the project was implementing a comprehensive energy management solution in order to:

  • Get a clear picture on electricity consumption that makes possible to undertake well-informed energy efficiency initiatives and adopt systematic energy management.
  • Optimize high energy consumption expenses (due to extensive use of energy for cooling equipment)
  • Reduce operational costs by optimizing the furnace energy consumption
  • Introduce a comprehensive approach to energy management to ensure continual improvement and low energy costs.
  • Get complete overview and control temperatures across different locations (warehouses, refrigeration facilities)

 

SOLUTION:

Solvera Lynx offered tools to reduce energy usage and optimize equipment performance. The data were recorded every 15 minutes and relayed to data-collection and analysis software GemaLogic. GemaLogic Energy Management platform provided consumption insights based on accurate energy data. This enables the Energy Team to have a clear view of energy consumption across the whole site, and thus to establish targets, track progress, and take immediate action when required.

 

RESULTS:

  • Automatical collection of energy data at strategic points on the production line
  • Loging the meter data and transfer this to GemaLogic on a daily basis
  • Analyses of the energy data to determine the cause of anomalies
  • Transparency over energy/water consumption and detailed analytics and insights into real-time energy consumption
  • Alarm system implementation (the detection of deviations and their causes in energy consumption and the possibility of quick action (e.g., water leakage)
  • Energy efficiency improvements through real-time monitoring advanced analyses and benchmarking

 

BENEFITS:

  • Identification of inefficiencies, and finding opportunities for systematic improvements and savings.
  • Optimization of energy use among the most significant energy consumers: HVAC, Process technologies and Cold Supply (refrigerators, freezing)
  • Reduction of energy consumption and costs without any negative impact on the production processes.
