Idan Ofer Invests $450 Million in US Infrastructure Firm After Zim Windfall

Idan Ofer's conglomerate, Kenon Holdings, is set to invest approximately $450 million for a 25% stake in ViZn Energy Systems, a U.S. infrastructure company specializing in district heating and cooling systems for hospitals, universities, and government buildings. The deal values ViZn Energy Systems at $2.92 billion and is expected to close in the second quarter of 2027.

This investment marks a significant new direction for Kenon, which recently concluded a highly profitable exit from its investment in the shipping company Zim. Kenon initially invested $200 million in Zim in 2014, which was part of a debt restructuring. Over the years, Kenon realized over $2.2 billion from Zim through stock sales and dividends, a return of more than ten times its initial investment, generating approximately $2 billion in profit.

ViZn Energy Systems operates heating and cooling infrastructure in 12 U.S. cities, including Boston and Philadelphia, serving over 700 clients through more than 140 miles of underground piping. The company reported revenues of about $611 million in 2025, with adjusted EBITDA exceeding $140 million. Its contracts are long-term, averaging around 15 years, with some payments indexed to inflation.

Kenon is partnering with funds managed by Harrison Street, a real estate investment firm. The consortium is expected to acquire between 60% and 100% of ViZn Energy Systems, depending on the seller's remaining stake. A group of lenders has committed up to $1.4 billion to finance part of the transaction and future operational investments. Kenon will hold a significant board presence and key decision-making rights.

This substantial investment in ViZn Energy Systems represents a major deployment of capital for Kenon following a period of asset monetization and capital distribution to shareholders. The $450 million investment is more than double Kenon's initial outlay in Zim in 2014, but comes after the significant returns generated from the shipping company.
