What should Cowlitz PUD customers plan before a service change?
For a panel upgrade or added load, Cowlitz PUD tells the customer to contact Engineering, submit a service application and meet an Engineering Planner onsite. Its service-modification category includes meter or transformer upgrades and reconnecting an idle meter; L&I approval is required before energization, and the PUD performs its own pre-backfill inspection.
What should a panel replacement estimate in Longview include?
A complete Longview panel replacement estimate identifies the equipment, circuit work, service capacity, permit holder and final inspection records. Meter and utility connection work should be priced separately from a panel-only replacement.
- Confirm the serving utility for this Cowlitz County address.
- Include the load-review basis and the equipment you want to add.
- Identify restoration, utility charges and inspection closeout in the written scope.

Calculation and uncertainty
Calculation: (B25034_007E+B25034_008E+B25034_009E+B25034_010E+B25034_011E)/B25034_001E. Variable: B25034 (year structure built). The derived share margin of error was not propagated. Source component and total margins of error are retained in the research data; this share is an estimate.
Building age does not establish electrical-panel condition or a need for replacement. Equipment condition and the planned work need their own assessment.
