From Gridlock to Growth: The policy, reform and infrastructure trends redefining energy investment

1. The investment story has moved beyond generation

A decade ago, the energy transition was a generation story. Today, it is increasingly a whole systems story. The industry’s next growth phase depends on assets that can connect, balance and optimise the system as much as those that generate electricity.

This shift is already influencing investor behaviour. Network infrastructure, battery storage, flexibility services and energy management platforms are attracting growing attention because they sit closer to the sector’s most significant constraints.

2. Grid access has become a defining investment theme

One issue reshaping the energy investment landscape is grid access.

Across the UK and Europe, connection queues continue to delay generation, storage and industrial projects. In 2024, the connections queue in Great Britain had grown to more than 700GW [1], necessitating reform.

The UK’s connection reform programme has refocused the queue from a ‘first come, first served’ to a ‘first ready and strategically aligned, first connected’ model. The intention is to reduce the risk of legitimate projects being stuck behind speculative and undeliverable projects. However, the reform timeline has slipped on several occasions, with Gate 2 offers now expected to be issued up to March 2027 [2]. Customers receiving Gate 2 offers have also reported incomplete or missing information. Investor uncertainty therefore remains, both as to when connection dates will be confirmed and the terms of the offers once received.

3. Demand growth is at the centre of the story

For years, many energy market forecasts assumed flat electricity demand. This is no longer the case.

The electrification of transport, heating and industry is increasing demand across the economy. At the same time, the rapid growth of data centres and artificial intelligence is creating new sources of electricity consumption. Network operators, policymakers and investors are all grappling with the implications.

Between November 2024 and June 2025, the demand connections queue in the UK rose from 41 GW to 125 GW [5] – a level of demand which exceeds existing grid infrastructure. In March 2026, DESNZ consulted on several proposals, including the use of new statutory powers to identify strategically important demand projects. Ofgem also issued an update in June 2026 [6] setting out options to progress demand connections which included the introduction of an independent transmission owner licence.

Given capacity challenges, data centre developers are considering behind the meter solutions. This could include co-locating data centres with renewable generation. As data centres require an exceptionally reliable and continuous power supply, intermittent renewable energy therefore needs to be paired with storage or back-up gas generators.

4. Clean Power 2030 has shifted the conversation from policy to delivery

The Government’s Clean Power 2030 agenda provides one of the clearest signals yet of the UK’s long-term direction of travel. Delivering a power system where clean sources produce at least 95% of generation by 2030 [3] will require substantial investment in renewable generation, storage, and supporting infrastructure.

The question is whether the sector can deliver at the pace required. Planning, permitting, supply chains, and workforce capacity have become key areas of project risk. The Government’s own assessment of clean energy skills in the workforce highlights the need for rapid reskilling and recruitment [4], which are already experiencing labour supply challenges.

Investors should remain mindful that energy policy is shaped by political priorities and can evolve over time. This is particularly relevant for assets whose returns are underpinned by government-backed support schemes. It remains to be seen if there will be any changes in priority following the recent appointment of Andy Burnham and Miatta Fahnbulleh.

5. Looking ahead

Private equity has played a significant role in financing renewable generation over the last decade. The next decade may look different.

The energy transition is no longer constrained by a lack of capital. It is constrained by execution. Grid access, storage, flexibility and market design have become the critical enablers of future growth.

The next generation of winners may not be those producing the most power, but those controlling the infrastructure through which power flows.

For investors, that distinction is important. As value continues to migrate towards the assets that enable the wider energy system, some of the most attractive opportunities may lie not in generating clean power, but in making clean power possible.
