This information outlines responsibilities for the two streetlight ownership options under Tariff Schedule 91 (PDF):

• Option A — for equipment owned and maintained by PGE.
• Option B — for customer-owned lighting equipment. PGE supplies the electricity and maintains the equipment.

Lighting design responsibilities

• Design layout for Option B streetlights (owned by the municipality):
  • Subdivision projects. For Option B streetlights (owned by the municipality), the developer is responsible to provide the PGE Lighting Design Specialist with the subdivision streetlight design layout stamped approved by the municipality under whose jurisdiction it falls. This approved layout is to be submitted simultaneously with the subdivision plans, to avoid delays with the PGE electrical plans.
  • Street improvements. For Option B streetlights (owned by the municipality) the municipality shall provide the PGE Lighting Design Specialist with a set of plans, which include complete streetlight design details.
  • Park improvements. For Option B streetlights (owned by the municipality) the municipality shall provide the PGE Lighting Design Specialist with a set of plans, which include complete streetlight design details.
• PGE will provide a streetlight design for subdivision, street improvement and park improvement projects:
  • Without charge for all Option A streetlight projects.
  • For a fee and subject to time constraints for Option B streetlight projects.

  The PGE Lighting Services Specialist will design the lighting layout to meet the recommended maintained illuminance values in the current revision of ANSI/IES RP-8 American National Standard Practice for Roadway Lighting, or the appropriate standard adopted by the municipality with jurisdiction over the project.

• Design alterations
  • Subdivision projects. When alterations are made by the developer or his contractor to either the approved streetlight locations, or to the luminaire and pole type, the developer is responsible to obtain approval from the municipality and to notify the PGE Lighting Services Specialist in writing prior to installation. In addition there may be a charge to alter PGE design sketches.
  • Street improvement and park improvement projects. The municipality with project jurisdiction must approve any design alterations. The contractor must notify the PGE Lighting Services Specialist of all changes in writing, including a set of plans clearly showing the alterations. There may be a charge to alter PGE design sketches.

  Note: In order to meet customer needs in a timely manner PGE must have adequate notice of design changes. If PGE is not given adequate notification of design changes PGE reserves the right to bill the developer, the municipality, or the designated contractor, responsible for the installation, for any costs to PGE associated with the changes. This billing may include, but is not limited to, the cost of additional trips, corrective trenching and conduit work etc.

• Approved materials
  To qualify for PGE maintenance under Tariff Schedule 91 Option B, all installations are to use only PGE-approved materials. See our approved list of streetlight luminaires, lamps, photo controls, poles, pole bases, mast arms, wire, and junction boxes. No substitutions are allowed. Materials installed are to also meet the standards of the local municipality in whose jurisdiction the development exists.

If the power source is a pad-mount transformer, the customer is to trench to within, but no closer than, two feet from existing energized transformers and primary conductors. The final two feet will be excavated by PGE, the cost of which will be paid by the customer or the customer should coordinate with PGE to assist customer at time of installation.
