Powerline Upgrade Project

Enhancing reliability to our region

We're upgrading a large transmission line in the city of Sacramento and portions of Sacramento County to provide more reliable service to our customers. We will be replacing three wires on the towers that run between the Hurley large bulk substation on Hurley Way and the Procter & Gamble co-generation plant on 83rd  Street. 

Beginning in late 2019, you may notice SMUD employees or our contractors performing work to replace the existing all-aluminum wire with an advanced aluminum composite wire along the 6.25-mile stretch.

The project has been designed to minimize construction impacts. We don’t anticipate service outages to local businesses or homes during construction.

Project benefits

Replacing the wires will allow SMUD to increase its overall transmission system flexibility to help ensure we can deliver reliable electrical service, particularly in the summer months when the demand for electricity is highest.

Public meetings

We held two public meetings to provide an overview and answer questions about the project.

Construction is scheduled to begin in late 2019, weather permitting.

The project is designed to minimize night work and noise impacts. However, we do expect some construction impacts, including:

  • Some heavy construction equipment such as cranes and trucks
  • Some multi-use trails and greenbelts along the route may be temporarily closed
  • Traffic control on roads where space does not allow for protective netting
  • Sections of parking lots along the route may be temporarily closed 

Impacted area

The project involves four main steps:

  1. To improve safety, we will install guard netting over public streets, roadways and highways or implement traffic controls where space is limited.
  2. Pulleys will be installed at each tower along the line to help remove the old wire and string the new wire behind it.
  3. The new wire will then be locked into final position. This process will be repeated for each section of the line.
  4. When all the sections are complete the line will be put back into service.

What’s the Powerline Upgrade Project?

SMUD is upgrading a large transmission line in the City of Sacramento and portions of Sacramento County to provide more reliable service to our customers. We’ll be replacing three wires on the towers that run from the Hurley substation on Hurley Way to the Procter & Gamble co-generation plant on 83rd Street

 What is the project schedule?
Construction is scheduled to begin in late 2019, weather permitting. The project time frame is designed to minimize the impact of construction efforts on the surrounding areas.

What construction impacts can we anticipate?
When the work starts, you may see heavy construction equipment such as cranes and trucks being used to replace the wires. To ensure the safety of our customers and crews, guard structures will be installed with netting over all public streets roadways and highways where space allows. The guard structures will allow for normal traffic to flow while the work is performed overhead. Where space does not allow for a guard structure, the contractor will perform traffic controls.

No power outages to residential or commercial customers are expected due to construction.

 What are the benefits of the transmission line upgrade?
Replacing the wires will allow SMUD to increase its overall transmission system flexibility to help ensure we can deliver reliable electrical service, particularly in the summer months when the demand for electricity is highest. 

 How will SMUD keep the community informed?
We’re hosting two public meetings to discuss the project and answer questions. We’re sending out announcements with meeting and project details to customers impacted by construction activities. In addition, we’re informing the media and including information on our social media platforms. We’ll keep this project web page up to date with progress and schedule updates.

We’re also happy to meet with any person or group about the project.

 When are the public meetings for the Powerline Upgrade Project?
We held two public meetings, on Monday, September 23, and Tuesday, September 24, to provide an overview and answer questions about the project.

Are there environmental impacts involved with replacing the lines?
We performed a California Environmental Quality Act (CEQA) assessment and have concluded that the project will have no environmental impact.
