Why is Backup Power Important?
Power outages are everyday occurrences in the US Can take hours to weeks to months to restore power Short of an earthquake, power loss is the WTP’s biggest vulnerability Expectation that drinking water will come online faster than power AWWA Best Management Practices recommend a backup power
source for minimum 40% - 50% WTP capacity
CRITICAL FACILITY: One of our missions as a water provider is
- reliability. This project is paramount in ensuring reliability.
SLIDE 4
Local power provider is Portland General Electric (PGE) Dispatchable Standby Generation (DSG) With 5MW of JWC power, the DSG program achieved 100MW of
dispatchable standby power
PGE provided funding incentives at completion of project for
additional equipment ($222,000) and aid in construction ($1,117,850 for 5MW)
PGE contract is for 10 years, with automatic 1-year renewals
thereafter unless terminated
Partnership Opportunity
SLIDE 5
While under contract, PGE provides:
- Monthly testing of the generators under load
- Diesel fuel – testing and fill-ups
- Preventative maintenance on generators and switchgear
- Engine tune-ups and general wear repairs
- Emissions DEQ permit modifications and renewals
- 24/7 monitoring and assistance
PGE may use the generators to offset peak loading (<50 hours/year)
Emergency operations by JWC always take priority

Fuel Considerations
How much fuel is the right amount?
SLIDE 25
After a large seismic event, fuel will be hard to get
Roads will be out Everyone will need fuel for utility repairs
Maintaining fuel quality
Diesel fuel degrades over time Biological growth and moisture create issues
Our solution?
48 hours of fuel Monthly fuel testing Fuel polishing system
