IN Brief:
- Partners Group has completed its majority investment in AVK, originally announced in August 2026 with an initial investment exceeding $1bn.
- AVK has appointed former UK energy minister Claire Perry O’Neill as chair while expanding its AVK Capital financing platform.
- The business reports more than 2GW of Energy-as-a-Service pipeline projects, which are prospective capacity rather than all commissioned plant.
AVK has confirmed completion of Partners Group’s majority investment and the appointment of Claire Perry O’Neill, a former UK minister for Energy and Clean Growth, as chair of its board. Partners Group announced the transaction in August 2026, describing an initial investment of more than $1bn. Completion and the board change are the developments confirmed on 4 November, as the company expands financing and delivery of on-site power systems for data centres.
AVK Capital is intended to finance, own and operate generation infrastructure for data centre developers. Under the company’s Energy-as-a-Service model, the customer buys electricity under a power purchase agreement without owning the generating plant or paying its capital cost upfront. This transfers specified financing and asset responsibilities to the provider, but individual contracts will still determine performance obligations, availability provisions and long-term commercial risk.
Power-system design does not become simpler because the generating equipment is financed by another organisation. The electrical capacity must match the intended facility load, while protection, controls, fuel supply where relevant, maintenance access and backup arrangements all affect operational resilience. Any plan to supply part or all of a data centre’s demand on site must address how power is maintained through equipment trips, maintenance and a change in operating conditions.
AVK describes an Energy-as-a-Service project pipeline of more than 2GW. The figure is a prospective development measure, not a statement that 2GW of generation has already been installed, contracted or commissioned. The company has not provided an asset-by-asset breakdown of those projects or quantified how much of the pipeline has reached planning consent, equipment procurement, construction or operation.
The business says its UK and European operations include more than 400 people across ten hubs and a modular manufacturing facility in Haydock. The facility supports production and assembly of power equipment, while the wider organisation works on design, delivery and maintenance for critical power applications. No new manufacturing output target, factory expansion cost or delivery schedule was announced alongside the investment completion.
Some data centre sites face long waits for public-grid connections, particularly where new substations or wider network reinforcements are required. On-site generation may allow a project to supply demand earlier or operate with a different import profile. It does not automatically remove planning, air-quality or fuel constraints and should not be treated as a universal substitute for network access; the feasible arrangement depends on the site’s load, energy source and connection configuration.
A multi-unit on-site generation system may have switchgear, protection relays, synchronising controls and, in some designs, batteries to bridge transitions or provide short-duration support. The controls need to manage load sharing, voltage and frequency, as well as safe isolation when faults occur. Operation in parallel with the grid has different technical conditions from intentional islanding, and AVK’s investment announcement does not identify one standard power architecture or technology mix for all prospective customers.
AVK cites a microgrid energised for PureDC in Dublin earlier in 2026 as evidence of delivered work. That is a separate project, not an installation arising from the newly completed ownership transaction. The company has not supplied a measured reliability figure or a list of new operational plants enabled by the Partners Group investment in its November statement.
Former minister Claire Perry O’Neill will work with chief executive Ben Pritchard, the board and Partners Group on the next stage of the business. Her background includes UK energy policy and previous senior roles across finance and climate-related organisations. The appointment is a governance change, and the company has not said it alters the technical specification of any operating power system.
Nicholas Pepper, a managing director at Partners Group, is also joining AVK’s board as an investor representative. The company says the investment will support further growth of AVK Capital, but it has not disclosed amounts already committed to specific sites under the new platform. Prospective pipeline capacity therefore cannot be used to calculate the number of operating generators, the capital deployed per megawatt or the electricity already supplied to customers.
The economics of an energy service contract depend on the cost and availability of electricity or fuel, the equipment’s load profile, maintenance obligations and how performance risks are assigned. An on-site generating facility used continuously has different requirements from standby power used only during outages. AVK’s disclosure identifies the financing model but does not give a standard tariff, generator fuel mix or emissions estimate across its entire proposed portfolio.
The completed ownership change and chair appointment establish the new governance and funding position. Subsequent project awards, orders, consents and commissioning will show how the financing model translates into delivered electrical supply. AVK has not published a timetable for converting its full reported pipeline into commissioned capacity.
