Transaction underscores growing importance of nuclear energy as extended plant lives, energy security priorities, and accelerating electricity demand reshape the sector
SUMMIT, NJ and SALT LAKE CITY, UT – April 6, 2026 – Energy Capital Partners ("ECP"), a leading investor across energy transition infrastructure, today announced a definitive agreement to acquire EnergySolutions, a leading nuclear company providing integrated solutions across the full nuclear lifecycle, from TriArtisan Capital Advisors LLC ("TriArtisan").
EnergySolutions is a leading international nuclear company, providing services across the full nuclear fuel lifecycle, including the safe transportation, processing, recycling, and disposal of radiological material. Headquartered in Salt Lake City, Utah and Charlotte, North Carolina, EnergySolutions operates across the United States, Canada, Asia, and Europe. It has a diverse base of customers including the U.S. and Canadian governments, commercial nuclear power generators, research facilities, national laboratories, and medical institutions worldwide.
“Today’s announcement marks an important milestone for EnergySolutions,” said Ken Robuck, President and CEO at EnergySolutions. “Over the past several years, we have broadened our offerings across the nuclear sector and strengthened our ability to deliver integrated solutions for customers. We believe this transaction will accelerate our long-term strategy and growth. We are proud of the work our team delivers every day, and we’re excited to work with ECP again as we build on our momentum and continue investing in our people and capabilities.”
ECP has a long-standing relationship with EnergySolutions and its management team, built through prior ownership. ECP’s decision to acquire the business again comes at a time of transformational change for the nuclear sector. Nuclear energy has emerged as a critical component of U.S. energy security, with bipartisan policy support driving significant regulatory reform and a national ambition to materially expand domestic nuclear capacity over the coming decades. With surging demand for baseload power from manufacturing, LNG, and data centers, utilities are extending reactor operating licenses rather than retiring assets, previously shuttered plants are being brought back online, and a newbuild market is emerging. This is creating sustained, long-term demand for EnergySolutions' waste management and nuclear services capabilities.
"We've stayed connected with EnergySolutions and its leadership since we exited our previous investment, and we've been impressed by what the team has continued to accomplish," said Drew Brown, Partner at ECP. “We see tremendous potential for its platform as the role of nuclear energy in meeting the rising need for reliable, baseload power continues to grow. EnergySolutions has built deep expertise in supporting nuclear facilities safely and responsibly throughout their lifecycle. We're excited to partner with them again as they continue serving their customers and contributing to a more secure energy future."
Under TriArtisan's ownership, EnergySolutions has seen significant growth, consistently executed with operational excellence, and served as a vital partner to its customers.
“We are grateful for the EnergySolutions team and what they accomplished during TriArtisan’s ownership,” said Gerald Cromack, Co-Founding Partner of TriArtisan. “The company has strengthened its platform and expanded its capabilities across the nuclear services market while maintaining an unwavering focus on safety and execution. We believe ECP is an excellent next owner for EnergySolutions, and we are pleased to support this transaction as the company enters its next chapter.”
The transaction is subject to customary regulatory approvals and is expected to close in 2026. Additional terms of the transaction were not disclosed.
