CoreWeave's current Kenilworth project page, checked October 28, 2026, describes approximately $150 million of electrical infrastructure investment, including a new substation serving NEST 11 and the surrounding community. This is not the site's total construction cost or evidence that the adjacent potential 100 MW expansion has started or opened. CoreWeave-controlled portion of NEST: NEST 11 conversion plus adjacent expansion land; not the entire former Merck/NEST campus. CoreWeave Kenilworth AI Data Center Campus is in Kenilworth, NJ, US and is a data center campus with under construction status.
