SERVICE INSTALLATIONS

DPP NUMBER DPP 500 P III-417

EFFECTIVE DATE 05/16/2025 SUPERSEDES 05/11/2023

APPROVED BY

1.0 PURPOSE

To establish a policy for charging customers for the costs of installation of new, additional, modified or temporary electric service, service removals, relocations and other distribution system modifications that may be necessitated by development, and customer-requested engineering, design work, and field services.

2.0 POLICY

Installation charges will recover all labor and upfront material costs incurred by the Department while performing work to install, modify, or remove customer connections.

2.1 Estimates. Estimates are provided upon request at no upfront charge. Estimates must be accepted and paid within 120 days of issuance. Estimates are subject to change if scope changes occur, or work does not begin within one year of estimate issuance. Any engineering design time beyond the initial 8 hours for a basic estimate will be billed to the customer, even if the project doesn't proceed.

2.2 Temporary Service Installations. Temporary services supply energy from the Department's distribution system to the point of termination at the customer's equipment; they may be single or three-phase and are typically used during construction of a building. Temporary services in place longer than one year require a written exception. The installation of a temporary service will be billed separately from permanent service installation.

2.3 Permanent Service Installations. Permanent services provide energy delivery from the Department's distribution system to the point of termination at the customer's equipment energized by the Department on a permanent basis. The Department will bill for all labor and material costs to design and install permanent services. In addition, an Amp Fee will also be assessed on all new and modified permanent services.

2.3.1 Amp Fee. In addition to charges for labor and material costs, all permanent services will be charged an Amp Fee (see Table 1) that reflects the amperage of new capacity added to the distribution system. Amp Fees will be listed separately from other installation charges and are not included in time and materials threshold calculations.

2.4 Electrical Usage During Construction. During construction, electrical service may be provided by either a temporary or permanent service connection. If electrical service is provided through an unmetered service connection, the customer will be billed a fixed amount based on estimated usage. Electrical usage during construction is charged at the Small General Service rate and billed on a separate utility account which must be paid separately from other project costs. Electrical usage charges do not apply to cost thresholds.

2.5 Installation Charge. The following policies apply to both temporary and permanent installations. Electrical usage, amp fees and administrative charges are not included in cost thresholds.

2.5.1 Standard Installation Service Looped Radial. Service installations with an estimated cost under $150,000 will be billed according to the standard charges in Tables 2 and 3. Charges must be paid in full before the Department starts any installation work. Standard charges are derived from the Department's typical labor and material costs and are updated annually or when costs change materially.

2.5.2 Non-Standard Installation Service - Looped Radial. Service installations not covered by a standard charge and with an estimated cost under $150,000 will be billed as a fixed amount, and not adjusted after the job is complete. Non-standard charges are derived from the Department's typical labor and material costs and are updated annually or when costs change materially. All fees, including 100% of the estimate, must be paid before the service can be connected and energized.

2.5.3 Non-Standard Installation Service above Time and Material Threshold. Looped Radial service installations with an estimated cost over $150,000, or any Network service installation estimate, will be billed based on actual time and material costs. A 20% advance payment of the estimate is due within 120 days of Service Letter issuance and must be paid before the Departments starts any installation work. All fees, including 100% of the estimate, must be paid before the service can be connected and energized. A final bill or refund will be issued after the job is complete to adjust for actual costs.

2.6 Additional Types of Work/Service. The cost of all work performed by the Department due to customer requests will be billed upfront. Incremental chargeable work includes, but is not limited to, establishing easements, meter enhancements, poles, line extensions, and equipment relocations. Tables 4-10 outline rates and charges for typical billable work. The following policies apply to various types of chargeable work, which may be included with standard charge or time and materials billings.

2.6.1 Make Permanent Work. Rewired services provided with temporary connections by non-Department personnel require permanent connection by the Department. If the customer commissioned the work, the Department may add the connection charge to the customer's utility bill. In this case, the Department may start work before installation charges are paid.

2.6.2 Additional Trip Charge. The Department will charge for each trip needed to complete the installation. An additional trip charge will apply if the crew arrives and finds the installation isn't ready as scheduled, doesn't meet safety or electrical requirements, or if a return trip is needed. If the customer requests an extra trip for service work, an additional trip charge will apply.

2.6.3 Safety Standby. The Department will provide safety standby for the contractor when making a connection to an energized Department facility. Standby service charges will be based on the hourly rates in Table 9.

2.6.4 Inspection/Review. The Department will inspect and review contractor-installed equipment and materials between the customer's service connection point and the Department's distribution system to ensure compliance with Department specifications, standards and requirements. These inspections will be charged at the hourly rates listed in Table 9.

Space Checks. Space checks to verify socket-to-unit panel wiring will be done at the customer's request or as required by the Department. Space checks are required for new multi-unit construction, rewired multi-unit buildings. Address changes for multi-unit buildings may require space checks. The customer is responsible for the cost of space checks, unless they are needed to correct Department errors.

Line Extensions. When overhead lines or underground conductors must be extended to serve new loads or three-phase loads in areas served by single-phase systems, the requestor will be charged for the cost of the line extension. Line extensions must be located within established public right-of-way or private property for which the Department has a permanent easement. Customer-owned three-phase line extensions are prohibited.

For underground extensions, the Department shall furnish and install the necessary conduit system, unless it is installed by a customer's private contractor. Costs include labor and materials, as well as the cost of any construction permits, inspection fees, all backfill, and other restoration costs.

Service Poles and Anchors. Service poles in the right-of-way or on private property that serve more than one customer service connection are installed and maintained at the Department's cost. Other service poles, such as poles to supply service to mobile homes, are the customer's responsibility for both installation and maintenance.

Service poles and anchors will be placed according to the Requirements for Electric Service Connection. Customers are responsible for incremental installation costs if they choose a more expensive pole location than the least costly alternative.

2.6.5 Pole and line relocations. Requesting parties must pay for pole and line relocations required by new or modified services or necessitated by development activities. A requesting party is also responsible for coordinating and meeting the requirements of any other affected parties (e.g., telecom utilities) impacted by the relocation. Any cost above and beyond direct pole replacement will be billed to the requestor.

2.7 Permissible Offsets to Charges. At its sole discretion, the Department may allow a customer to construct utility infrastructure as part of their service installation. Once service installation is complete, the Department will credit the customer up to the Department's cost savings solely attributable to the customer-constructed infrastructure. Any customer work completed under this Section must be approved by the Department in writing and included as an addendum to the service request.

2.8 Final Connections. Final connections to the distribution system to energize the customer's service are made solely by the Department, without exception.

2.9 No Backup Service. Backup or alternate service shall not be installed or provided to customers unless there is a demonstratable public need for such backup service. The Department shall be the sole determinant of whether a request for backup service qualifies as a public benefit. Contracts for backup service that are already in effect will continue to be honored.

Administrative Charge. Fees in the following tables will be subject to an additional administrative charge. The administrative charge recovers taxes the utility incurs performing service connections and will be added to the final bill for the service connection. Like the amp fee in Section 2.3.1, the administrative charge is not included in time and material calculation thresholds.

Standard Charges

120/240 Single-Phase $6.36 200

120/208 Single-Phase $5.51 231

240/480 Single-Phase $12.72 100

277/480 Single-Phase $12.72 100

120/208Y Three-Phase $8.65 133

120/240 Three-Phase (Open Delta) $9.98 115

7,960/13,800Y Three-Phase $573.66 2

15,240/26,400Y Three-Phase $1,080.80 1

Examples to illustrate the Amp Fee computation for various service types:

1) New 200A service at 120/240V Single-Phase:

Amp Fee = $6.36/Amp * (200 Amps - 200 Amp Credit) = $0

2) New building with two 3000A and one 400A service at 120/208V Three-Phase:

Amp Fee = $8.65/Amp * (6400 Amps -133 Amp Credit) = $54,209.55

3) Existing service rewired from 4000A to 5000A at 277/480V Three-Phase:

Requested amps: 5000 - 4000 =1000A

Amp Fee = $19.95/Amp * (1000 Amps - 58 Amp credit) = $18,792.90

4) Existing service rewired with no increase service size (e.g. 600A to 600A)

Amp Fee = $0.

Note: Amp Fee is separate and not included in the time and materials billing threshold.

3.0 DEFINITIONS

3.1 Additional Trip Charge. The trip charge includes the labor duration for average service territory travel time, safety tailboard, material handling/loading, and site setup.

3.2 Enlarged/Expanded Service. An increase in the electrical load-carrying capacity of a customer's service. If a premise has an existing service that exceeds the ampacity limits in the "Requirements for Electric Service Connection" manual, any load additions that require additional service installation work by the Department are considered enlarged/expanded services.

3.3 Looped Radial. The Department's distribution system outside of the network areas that has a single source of supply. Also referred to as "Non-Network."

3.4 Network. Distribution service from multiple sources of supply operating in parallel, which offers a high degree of reliability. Network service in Seattle can be found in Downtown, South Lake Union, University District and First Hill neighborhoods.

3.5 Point of Termination. Where the Department's system ends and connects to the electrical system owned by the customer.

3.6 Service. Energy delivery from the Department's distribution system to the point of termination at the customer's equipment.

3.7 Service Removal. The removal of all Department-owned electric service equipment including electrical conductors and meters. In the case of very large services, removals may include transformers and transformer meters.

3.8 Service Size (or Service Rating). The greater of the maximum nameplate ampere rating of the main service disconnect and the main service panel. In the absence of a single main service disconnect, the service rating is defined as the maximum nameplate rating of the main service bus or the rating of the main busing in the service entrance panel, whichever applies. In buildings where multiple services are connected from one service drop or lateral, the service rating for the building shall be the sum of the individual services.
