Vineyard Wind Can Not Power 400,000 Homes 24/7

News media report that Vineyard Wind will generate 800 megawatts of energy, enough to power 400,000 homes

.

In a Boston Suffolk Superior Civil Court case 2684CV01041 Vineyard Wind 1 LLC vs. GE Renewables US LLC, a document was filed on May 11, 2026.

.

In item # 6, it states, "With respect to production output, I understand that nameplate capacity and actual production are two distinct concepts."

.

This means a wind turbine's nameplate capacity is its maximum theoretical power output under ideal wind conditions (e.g., 13 MW).
In contrast, actual production is significantly lower, typically averaging only 25%–40% of that capacity over a year due to variable wind speeds, maintenance downtime, and energy losses.

.

Ultimately, the Vineyard Wind project will not produce enough energy in a year to power 400,000 homes.
