Energy Capital Partners (ECP) has re-acquired EnergySolutions, marking its return to the nuclear services sector after a prior ownership stint. The private equity firm is purchasing the business from TriArtisan Capital Advisors, reflecting renewed confidence in nuclear infrastructure amid rising energy demand. ECP previously owned EnergySolutions, which provides integrated services across the nuclear lifecycle, including transportation, processing, and disposal of radiological materials for global government and commercial clients.

The transaction underscores the sector's strategic importance, driven by energy security priorities and regulatory support for reliable baseload power. ECP highlighted its long-standing relationship with the company and its management team, positioning the deal as a continuation of a proven partnership. Drew Brown, ECP Partner, emphasized the platform's potential as nuclear energy's role in meeting rising power needs grows.

TriArtisan, which expanded EnergySolutions' capabilities during its ownership, expressed confidence in ECP as the next owner. The deal is expected to close in 2026 pending regulatory approvals.
