Southern California Edison Awards San Onofre Nuclear Plant Decommissioning Contract to AECOM, EnergySolutions Joint Venture

ROSEMEAD, Calif., Dec. 20. 2016 — Southern California Edison today announced, after a 10-month competitive bid process, it has selected a joint venture of AECOM and EnergySolutions as the Decommissioning General Contractor for the San Onofre Nuclear Generating Station (SONGS). It is one of the country’s largest commercial nuclear plant decommissioning projects

“We are pleased to announce the selection of the AECOM/EnergySolutions team, a global joint venture with extensive commercial and government decommissioning experience around the world, as the prime contractor to safely and efficiently dismantle the San Onofre nuclear plant,” said Ron Nichols, SCE president. The joint venture will be known as SONGS Decommissioning Solutions.

“SCE will maintain strict oversight of the contractor and will continue to engage with the community and all stakeholders during decommissioning,” Nichols said. He noted that the major dismantlement work will not begin before 2018 when state regulators are expected to complete their environmental reviews, as required by the California Environmental Quality Act.

The project is expected to create about 600 jobs during the 10-year dismantlement phase, including workers from local companies.

AECOM, a fully integrated global infrastructure firm, was named one of Fortune magazine’s “World’s Most Admired Companies” in 2016. AECOM designs, builds, finances and operates assets in more than 150 countries. EnergySolutions specializes in nuclear plant decommissioning and waste management, and is currently in the demolition phase of decommissioning both the Zion and Dairyland nuclear power stations.

The $4.4 billion nuclear plant decommissioning is financed through existing trust funds, including SCE’s share of the project as majority owner. The total cost includes the dismantlement work awarded to SONGS Decommissioning Solutions, continued on-site storage of San Onofre’s used nuclear fuel until the federal government provides a required repository and restoration activities.

SCE shares responsibility for decommissioning with San Onofre co-owners San Diego Gas & Electric and the city of Riverside, and former co-owner, the city of Anaheim. When operational, San Onofre Units 2 and 3 generated 2,200 megawatts of electricity.

SCE announced in June 2013 that it would retire San Onofre Units 2 and 3, and had begun the preparations to decommission the facility. SCE has established core principles of safety, stewardship and engagement to guide decommissioning. For more information, visit
