Palmer to Ware
Improvement Project
The Palmer to Ware Improvement Project is a proposed transmission line project
that will upgrade an electric transmission line in Central Massachusetts known as the O15N Transmission Line.
National Grid's Palmer to Ware Improvement Project is a proposed transmission line project upgrading the O15N electric transmission line. The upgrade will focus on portions of the 10.35-mile-long segment of overhead power lines southeast of downtown Palmer, crossing Route 20 and the Massachusetts Turnpike (I-90), continuing northeast until it crosses Route 9 and Route 32 located northeast of downtown Ware. Although the line will be rebuilt to a 115 kilovolt (kV) standard, it will continue to operate at 69kV for the foreseeable future. Once upgraded, the newly rebuilt transmission line will provide enhanced electric reliability for the region.

National Grid identified a need to rebuild the O15N transmission line due to asset condition and reliability concerns. The upgrading of the aging infrastructure is more cost effective than continued long term maintenance. The line will be replaced with modern technology and built to the most recent National Electrical Safety Code standards, improving safety, performance, and reliability.
No. If property rights are needed from a landowner to construct, operate, or maintain the Project facilities, National Grid will contact the landowner to explain what rights are required and begin good faith negotiations for such rights
No, the company has no plans to obtain new easement rights from property owners. If a need develops, the company will begin conversations with the individual landowner. If you have a question about an existing easement or if you are unsure if you have one, please contact us.
National Grid prohibits all unauthorized use of its property and will take steps to limit access to the right-of-way (ROW). If specific problems need to be addressed, National Grid will work with property owners and notify local authorities to resolve the issue. Measures to prevent unauthorized access to the ROW can include signage, access gates, traffic cones, and fencing.
The corridor is already cleared to its full extent; however, the company will have to mow and selectively remove trees along access routes to accommodate construction equipment.
National Grid will work with you to discuss any items under the transmission line. If you have a concern, please use the "Contact" form below.
The proposed structures are taller than the existing structures because they are being built to 115kV standards. These new standards need greater clearance due to their configuration and design specifications which will provide greater protection from lightning strikes and tree contacts. The current structures are an average of 60 ft in height, the proposed structures are an average of 90 ft in height.
The company is doing so to avoid the cost and disruption of another project in the future. The Project is unavoidable since the existing line must be replaced now.Even though the rebuilt line will continue to operate at 69kV, the company anticipates that increasing electric demand will require operating the line at 115 kV within the expected design-life of the new structures.Thus, the company is taking advantage of this opportunity to rebuild the line to 115 kV design specifications now to minimize the potential for future upgrade work, improve system reliability, greatly reduce future environmental impacts, and provide long-term cost savings for customers.
The Project is currently in its engineering/permitting stage (see Permitting above). It is anticipated that construction will start in 2026 and the rebuilt line will be completed and in service by 2028. That timeline may shift due to permitting approvals and other requirements that National Grid must meet. Please check back here or contact us for updated information.

Rebuilding an electric transmission line involves a variety of activities set out in phases. Below are sample descriptions and photos; actual construction sequencing, methods, and materials will vary.
1. Site Preparation:
The first phase of site preparation and construction is tree and brush removal. Vegetation maintenance allows construction crews to build access roads and remove trees in danger of falling into transmission lines.
2. Environmental Controls:
Next, environmental controls would be installed to mitigate construction impacts to the area. These can include matting, silt fences, and concrete washout structures and containers, among others.
3. Transmission Line Rebuilding:
The next phase would be transmission line rebuilding, where foundations are poured, structures are spotted and erected, fiber optic cable is installed, and new wire is strung and energized. Old structures will be removed from the right-of-way. This work would be done with a variety of equipment, including cranes and other heavy equipment.
4. Restoration:
The final phase of construction is ground surface restoration, in which the construction area is restored to its pre-construction condition (unless otherwise specified in regulatory requirements or landowner agreements).
