Investment portfolio

  • Takanock

    Led · Equity · Jun 2025

    Takanock provides integrated digital and power infrastructure solutions aimed at addressing power shortages that limit data center development in Tier I and II markets. Founded in 2023 and led by Kenneth Davies (founder of Google Energy and former head of Microsoft's renewable strategy globally), the company spent its inaugural year engineering a scalable approach to solve critical energy constraints for data centers. In June 2025 Takanock secured $500 million in capital commitments from ArcLight and DigitalBridge to accelerate development in constrained markets. Its offerings include flexible on-site power solutions that can serve as prime power until substations are completed and thereafter operate as wholesale grid resources, while sidestepping pipeline capacity constraints and firm pipeline contracts. Takanock emphasizes sustainability through highly dispatchable resources, best-available emission-control technologies, and closed-loop cooling to minimize environmental and water impacts and support greater integration of renewables. Since early 2024 the company has assembled a strategic U.S. portfolio and is executing digital power deployments under long-term contracts at late-stage projects in Northern Virginia and Phoenix; Houlihan Lokey served as exclusive financial advisor on the transaction.

  • Elevate Renewable Energy

    Led · Equity · Jan 2023

    Elevate develops and operates large-scale battery energy storage and solar projects to provide reliable, dispatchable capacity and support growing electricity demand. Its portfolio includes the recently acquired Prospect Power Storage project (150 MW/600 MWh), currently under construction and scheduled to begin operations in mid‑2026. Elevate was also selected by the New Jersey Board of Public Utilities for the 150 MW/600 MWh Garden State Reliability (Two Rivers Storage) project at the Bergen Generating Station. The company pursues equipment financing and supplier finance solutions to improve working capital, supply chain resilience, and project execution speed. Elevate positions its projects to serve high-demand customers such as data centers and to increase grid resilience and clean energy utilization. The company is a portfolio company of ArcLight Capital Partners.

  • Zeem Solutions

    Led · Equity · Jul 2022

    Zeem Solutions operates zero-emission fleet depots and provides a fleet-as-a-service for medium- and heavy-duty fleets, bundling vehicle leasing, charging, secured parking, maintenance, cleaning, and driver amenities. The company supplies battery-electric trucks, vans, and shuttle buses on a flat monthly fee that the firm says is lower cost than owning and operating gas or diesel fleets. Zeem positions its depots as centers for opportunity charging and specialized EV operations, handling permitting, infrastructure installation, hardware/software integration, and maintenance for customers. The company announced a $50 million capital commitment from a fund managed by ArcLight Capital Partners to expand its business model and accelerate national depot growth. It also entered a strategic partnership with LAZ Parking Realty Investors, which will become an equity partner and co-develop charging and service depots using LAZ’s site selection, acquisition, and construction capabilities. The company launched its first LAX-based depot with nearly 100 available electric vehicles, 77 fast charging ports and 53 Level 2 chargers, and plans to scale depots nationally to accelerate fleet electrification and clean mobility deployment.

  • Inspiration Mobility

    Led · Equity · May 2022

    Inspiration Mobility is a sustainable infrastructure platform dedicated to accelerating the electrification of transportation by investing in, owning and managing the real assets that enable the EV transition. Its first two operating businesses, Inspiration Fleet and Inspiration Energy, provide integrated solutions that reduce the cost and complexity of electrification for fleets. Inspiration Fleet is described as the world’s first EV-only Fleet Management Company (eFMC), financing EVs and providing fleet management services for light-duty fleet businesses, including payment plans that can bundle vehicle and charging costs and aggregate payment across depots, public stations and in-home chargers. The company says the new capital will enable it to accelerate work electrifying commercial fleets and reduce costs and greenhouse gas emissions for customers. The announcement reports an additional $215 million raised, bringing total investable capital to $415 million. The release cites market metrics the company targets: roughly 3.5 million light-duty vehicles are operated by 600–700 fleet owners in the U.S., driving about 158 billion miles and emitting about 64.5 million metric tons of CO2 annually. Inspiration is an EV asset financing company that provides balance-sheet capital to finance vehicles and related charging and energy infrastructure for commercial fleets. The firm offers full‑stack or a la carte solutions—financing vehicles, designing and operating charging systems, and coordinating energy services—for emerging EV fleet operators, corporate fleets, and other fleet use cases. It came out of stealth after operating since the end of Q1 and has Revel as an early customer, helping that operator source 49 EVs. Inspiration plans to build, own and operate charging infrastructure and to finance complementary energy assets such as solar, energy storage and real estate. Founder and CEO Josh Green says the company aims to expand into light and medium-duty segments across North America. The business launched with a $200M capital commitment intended as balance-sheet/platform capital to fund infrastructure assets and general corporate purposes.
