Main Dashboard - Plant Overview Actual current energy performance v target values Title of the display Trend display for the indicator KPI including target Baseline, Current value and Target for the selected time level D Navigation matrix: Columns represent different type of displays to be activated. Rows represent process areas. The selection is shown by highlighting. Color of the traffic light next to process area indicates deviation from the target. Navigation within the process hierarchy is possible. February 1, 2013 Slide 9
Monitoring & Targeting (Module 1) Sub-process analysis The key is to be able to accurately predict the electricity consumption based on real time data Accurate electricity plans reduce demand charges and lower penalties Improvement of 10% in electricity plan accuracy results in 1% savings in electricity costs February 1, 2013 Slide 10
Monitoring & Targeting (Module 1) Display template hierarchy Main overview Allows drill-down to Process area for specific details, e.g, Energy efficiency Targets, Settings Analysis and Reports Energy efficiency trend Subprocess overview Energy overview Target setting Report Analysis February 1, 2013 Slide 11
Monitoring & Targeting (Module 1) - Energy Overview You can select whether you want to display Energies, Costs, CO2 or SEC Time level selection. You can select the time level and navigate. In this example one WEEK is selected You can select which energy form you want to display, or Total Trend selection: Periodic shows periodical values. Cumulative shows sum from the beginning of the time selection This graph shows the selected year and previous year values for Energy, Costs, CO2 or SEC (depending on what is selected above) The losses are shown here divided into two parts: operational losses and partial load losses.
