Agriculture Survey

Farming is a time-honored tradition in New York and an important part of the economy. Much of the lands surrounding the existing Inghams-Rotterdam transmission corridor in the Mohawk Valley are used for agricultural purposes. 

As part of National Grid’s ongoing outreach efforts to better understand the agricultural activities taking place on adjacent lands, we are conducting a survey to gather information from farm operators. This information will help inform construction plans for the project. Our team is committed to working with area farmers to minimize disruption to agricultural lands during construction activity to the extent possible. 

We would appreciate you taking the time to complete the survey, located at the link below. If there are active leased farming operations on your land, we ask that you include the lessee’s contact information. If you have any questions or difficulty filling out the survey, please contact our team at 877-551-4743 or [email protected].

Current Activities

The project received approval of its Article VII Permit from the New York Public Service Commission on May 15, 2026. Environmental Management and Construction Plans will be submitted in the coming weeks.

Construction‑related permitting and preparations for a project marshalling yard in St. Johnsville is actively underway. Permitting work will continue as each transmission line segment approaches its scheduled construction window.

Construction of Segment 6: Inghams to St. Johnsville began on June 8, 2026. Early activities include right‑of‑way staking, mowing and tree clearing, and installation of access roads. Construction on this segment will continue through January 2027.

Planning and design efforts continue across the remaining transmission line segments. This includes detailed reviews of transmission corridors and field walkdowns with National Grid staff and contractors to support final design, access planning, and construction preparation.
