North Sky Announces Close of Sustainable Infrastructure Fund IV

Minneapolis, MN – North Sky Capital (“North Sky”) a pioneer in impact investing for more than two decades, has closed Sustainable Infrastructure Fund IV (“SIF IV”) to new investors. SIF IV is the fourth offering within the firm’s sustainable infrastructure strategy and firm’s 10th impact fund. SIF IV has already made two initial investments across energy storage and community solar, and North Sky continues to see strong interest from co-investors looking to participate alongside the fund in future projects.

Despite a complex fundraising environment marked by evolving local and federal policies on trade, tariffs and taxes, North Sky’s pipeline of compelling investment opportunities in the energy transition remains strong. The firm is steadfast in the strategy’s investment thesis and optimistic about secular trends driving opportunities in energy storage, community solar, smart grid, renewable fuels and related areas today. SIF IV supports North Sky’s long-standing mission of investing in sustainable infrastructure projects that support a cleaner, more resilient energy future.
