1. Proficy Workflow for Small/Medium Utilities Wholesale Power Cost Calculations Use Case

2. Electronic Standard Operating Procedures (eSOP) Electronically guide operators through step-by-step instructions Ensure operations comply with defined processes - with validated entry Capture both automated and manual data entry Digitize and enforce compliance with policy manuals and SOPs Decrease: Costs by reducing errors and waste Training time through electronic instruction Risk by enforcing SOP compliance Increase: Quality of operations by reducing errors Ability to manage assets properly Compliance by enforcing SOPs

3. Alarm Management and Corrective Action Don’t just acknowledge alarms - take action! Automatically respond to problems and events Correct for alarms in real time Minimize nuisance alarms Ensure proper action on critical alarms Monitor alarms from multiple systems Send tasks to people or other systems Store operations data for analysis

4. Use Case Wholesale Power Costs Calculations Utility Need: Utility purchases wholesale energy from a variety of bi-lateral sources. Loads above scheduled levels cost substantially more. Utility is not profitable during those time periods. Identify when this is occurring and how much money is at risk

5. GE Solution Work Process Management With GE’s Proficy Workflow, utilities can digitize work instructions and configure logic trees to identify when specific events have started to occur - and take appropriate actions. In this use case, Proficy Workflow: Looks at the sum of the retail loads (either retail meters or wholesale delivery meters) Provides a running value for wholesale power costs

6. Utility Load

7. Wholesale Portfolio At 3pm, the load exceeds a 12MW block contract. As load increases, the next higher priced block is used which increases the average price/MWh purchased.

8. Average wholesale supply costs
