In September 2018, I Squared Capital announced the closing of its ISQ Global Infrastructure Fund II at the US$7 billion legal cap, exceeding an initial target for the fund of US$5 billion. The fund received commitments from over 100 institutional investors with oversubscribed demand and a re-up rate over 80 percent from Fund I. The firm has made investments in the U.S. hydroelectric power industry, in China's waste water treatment industry, and in India, including a majority stake in the 109-kilometer Jaipur Mahua Tollways in the northwestern state of Rajasthan, and a stake in the rooftop solar power company Amplus Energy Solutions Private Limited. I Squared's hydro-electric power investments have been made through its portfolio company Cube Hydro Partners LLC, which was formed in January 2014. Cube Hydro owns and operates 14 hydroelectric power facilities in the U.S. and purchased four more plants in 2016. Kristina M. Johnson, a former undersecretary for energy at the U.S. Department of Energy, is the CEO of Cube Hydro.

The investment will add hydroelectric and natural gas generation plants, transmission infrastructure, and natural gas processing facilities, totaling 2,300 megawatts of energy. The assets are located in Peru, Chile, Ecuador, Guatemala, El Salvador, and Argentina. The transaction for the purchase of these assets from Duke Energy was completed in December 2016.
