16. Transmission Monitoring NB Power oversees the Maritime Control Area Standards for responding to loss of load or generation NB Power is responsible for maintaining 60 Hz frequency on grid We adjust the frequency by raising/lowering load on units PI used to demonstrate compliance, prepare reports NB Power oversees the Maritime Control Area Standards for responding to loss of load or generation NB Power is responsible for maintaining 60 Hz frequency on grid We adjust the frequency by raising/lowering load on units PI used to demonstrate compliance, prepare reports

18. Opacity Monitoring Provincial regulations stipulate that our Dalhousie plant must report an exceedance if we exceed 20% opacity in any 4 minutes of a 20 minute period > Very difficult to calculate using DCS > Many spikes due to rapping Solution - PI-API!

19. Opacity Monitoring NT service written in C Runs on PI server Tracks opacities for each unit Should an exceedance occur, it > generates a report of opacities during the period > alarms the unit operator NT service written in C Runs on PI server Tracks opacities for each unit Should an exceedance occur, it > generates a report of opacities during the period > alarms the unit operator

30. Equipment Running Hours Machinery needs periodic maintenance (lubrication, vibration testing, etc.)

31. Equipment Running Hours Done in past with PIM (Periodic Inspection and Maintenance) work orders > Time-consuming > Manpower-intensive Current maintenance done on a running hours basis Some equipment not attached to DCS Solution - PI with manual entry Done in past with PIM (Periodic Inspection and Maintenance) work orders > Time-consuming > Manpower-intensive Current maintenance done on a running hours basis Some equipment not attached to DCS Solution - PI with manual entry

Electricity Marketing NB Power sells energy to Eastern Canada and into the New England power market Our Marketing group uses PI to track energy prices actual sales unit availability air temperatures billing NB Power sells energy to Eastern Canada and into the New England power market Our Marketing group uses PI to track energy prices actual sales unit availability air temperatures billing

36. Outage Costing Unit outages (trips) result in: increased fuel cost for replacement power lost revenue and/or opportunities Marketing uses PI to tie lost megawatts and lost sales together to put a dollar value on an outage Unit outages (trips) result in: increased fuel cost for replacement power lost revenue and/or opportunities Marketing uses PI to tie lost megawatts and lost sales together to put a dollar value on an outage

37. Outage Costing PI provides critical information: actual costs of an outage cost of restoring unit quickly vs. lost revenue/opportunities PI provides critical information: actual costs of an outage cost of restoring unit quickly vs. lost revenue/opportunities
