Select Private Holdings
A selective view of private positions illustrating how Summer Hill deploys evergreen capital across three long-term themes.
Additional investments held through co-investments and specialist funds remain confidential.
1. Energy-Transition Infrastructure
Theme thesis: Electrification and decarbonisation require new generation as well as distributed infrastructure. SHCP balances contracted yield with pipeline growth to achieve steady cash flow and capital appreciation.
Invenergy LLC
North America's largest privately-held renewable-power developer
Investment Thesis
Ownership gives SHCP direct exposure to utility-scale build-out with long-term offtake contracts. Returns are anchored in operating cash yield while Invenergy's 30 GW pipeline supplies reinvestment optionality.
Generate Capital PBC
Developer/owner of distributed sustainable-resource assets
Investment Thesis
The "infrastructure-as-a-service" model offers contracted, inflation-linked cash flows and diversification across sub-sectors. Generate's scale and balance-sheet funding complement Invenergy's greenfield focus.
Cypress Creek Renewables
U.S. utility-scale and community-solar IPP
Investment Thesis
Participation in the sponsor equity allows SHCP to capture mid-market solar growth, benefit from storage co-location and support decarbonisation of regional grids.
2. Climate-Adaptation Solutions
Theme thesis: Water stress, soil degradation and physical-risk disclosure drive demand for adaptive solutions. The portfolio captures value in nature-based credits, resilience analytics and essential water assets.
Indigo Ag Inc.
Carbon-farming programs and biological inputs provider
Investment Thesis
Carbon-credit revenues create an aligned incentive for regenerative practices; exposure gives SHCP a scalable, nature-based mitigation and adaptation play tied to Scope-3 demand from corporates.
One Concern Inc.
SaaS platform for climate and disaster risk analytics
Investment Thesis
As climate risk pricing migrates from actuarial averages to asset-level analytics, One Concern's data set becomes critical infrastructure; minority stake positions SHCP in the emerging resilience-data stack.
Seven Seas Water Group
Water-as-a-Service® owner/operator
Investment Thesis
Reliable potable-water supply is cornerstone adaptation infrastructure. Long-term municipal & industrial contracts deliver predictable real-return cash flows with low correlation to power markets.
3. Strategic Infrastructure & Essential Services
Theme thesis: Transport, data and freight networks underpin economic security. By holding privately controlled platforms with durable competitive positions and regulated or contracted cash flows, SHCP accesses predictable income and strategic option value.
EdgeConneX Inc.
Global edge-to-hyperscale data-centre platform
Investment Thesis
Rising AI and low-latency workloads require proximate capacity; EdgeConneX offers contracted power-dense assets with inflation pass-through and proven development pipeline, diversifying SHCP's digital exposure.
Genesee & Wyoming Inc.
Short-line freight railroad operator
Investment Thesis
Freight rail is energy-efficient, hard-to-replicate infrastructure. Stable volume-based cash flows plus bolt-on acquisition strategy provide inflation-protected yield and capital growth.
Zayo Group LLC
Mission-critical dark-fiber & bandwidth provider
Investment Thesis
Fibre backhaul is foundational to cloud, 5G and edge computing. Zayo's long-haul and metro networks generate utility-like recurring revenue while offering upside via small-cell and hyperscale demand.
