Energy is the largest unmanaged industrial expense
30% US energy consumption, 70% growth by 2035
Over 60% of Fortune 100 companies public announcements
2015 UN Climate Change Initiative, less than 15% use software*
Many not tracking to targets
30-70% unplanned downtime due to PPQ ($$$) **
Energy management can result in substantial savings

Step 3: Customized Reporting and Actions
• Industry Standard Philosophy, Guide, Format
• Design of the customizable HMI – design meets operations• Uses network to communicate RTU/PLC – 4 Vs• Questionnaires, interviews, workshops - KPIs• Diagrams (PFDs and P&ID) used as source documents*• Displays – navigation hierarchy, realms, scope, security
• Think Big Engine – scale, evolve, custom, open standards• Alerts, Alarms and Notifications (Hierarchy, time, link)• Historian, trends, reporting, alarming, backup, security

How Value Is Presented
Add a footer 15
• KPI Reports, Dashboards and Templates• Alarm Reporting (trend, severity, type, custom)• Efficiency Reporting (OEE, OXE)• 1159 Power Quality Reporting (into the plant)• PQ Impact – Health and Diagnostics Reporting• Custom Reporting
• User Support Critical – know the Ws• If user don’t like, recognize, understand – they won’t use
• Evolution Path – from Basic to Advanced Analytics• How can the HMI be used to display other insights?• Correlation of data – root cause analysis• Advanced analytics (predictive and preventive diagnostics)

To the CloudsPQ in the Cloud is a Game Changer
• Amazon – A Data Company
• Chambers 2014 World Economic Forum
• PQ + Data = Today’s Manufacturing Home Run
• Cloud Based Hosted Services• Fast delivery of services, 3 legged stool critical• Rapid ROI (CapEx, OpEx)• Focus on core competencies, outsource experts to allow team focus
• What’s In Store for Tomorrow• Quickly moving to advanced analytics (predictive / preventive)• Beyond Pareto, OXE
Focus on the value drivers – the solutions become clear
