A reflection on a UK industry panel, the ARMSA Academy decision context model, and what becomes harder to see when developers are working under macro pressure.
What this piece argues, in three sentences
UK connections reform is a macro factor squeezing the space in which renewable project developers can make good early-stage decisions.
The senior developers on a recent industry panel were articulate about the financial and capacity consequences, but the conversation didn’t quite reach the construction and operational safety consequences travelling alongside them.
The ARMSA Academy Decision Context Model is a useful lens here, not because it explains that omission, but because it makes visible how macro factors set the constraints within which projects operate, and why developers need to trace the downstream lifecycle implications of decisions made under those constraints.
I sat in on a UK industry panel on connections reform recently. Four senior developers in front of an audience of their peers, an experienced moderator, an hour of remarkably honest discussion. One of the panellists framed the developer mood as the stages of grief: shock, denial, anger. He got laughter that was a little too quick, a little too knowing.
It was the kind of session where the value isn’t in any single contribution. It’s in the cumulative weight of what concerns are surfaced, and which ones aren’t. I’ve been turning it over since.
What is connections reform, briefly
For readers coming in cold: connections reform is the most significant overhaul of how renewable energy projects connect to the UK electricity grid in decades. It is led by the National Energy System Operator (NESO), with regulatory approval from Ofgem and policy backing from the UK Government’s Clean Power 2030 Action Plan.
The old “first come, first served” model produced a connection queue of around 750GW by early 2025, roughly four times what Great Britain actually needs to meet its 2030 clean power target. Speculative or stalled projects held queue positions ahead of viable, ready-to-build ones. Investment was blocked.
The new “first ready and needed, first connected” model (the reform package is technically called TMO4+) prioritises projects on two criteria. Readiness means demonstrable land rights and planning progress. Strategic alignment means the project fits the technology mix the country needs under the CP2030 Action Plan.
Projects pass through Gate 1 (indicative offer) and Gate 2 (firm offer if readiness and alignment are evidenced). Within Gate 2, projects are then split between Phase 1 (those scheduled to connect by 2030, supporting the Clean Power 2030 target) and Phase 2 (those scheduled to connect between 2031 and 2035, supporting longer-term system needs).
In December 2025, NESO published the new delivery pipeline: 283GW of projects prioritised for connection, of which 132GW are aligned with delivering Clean Power 2030. The reform is intended to unlock around £40 billion of clean energy investment a year. The principle is widely supported across the industry, including by every panellist I heard. The transition itself, as the rest of this article reflects, is where the friction lives.

What the panel was wrestling with
The developer pain is real and well-defined. Connection offers are arriving with appendices missing. Gate 2 connection agreements that should anchor procurement are still not in hand for projects with scheduled 2026 and 2027 delivery dates. Bidding into the next CfD round means signing turbine contracts without certainty about when, or whether, the connection will actually arrive, thereby pricing in risk that wouldn’t otherwise be there.
Multi-technology projects (a single development combining, for example, solar with battery storage) are now being assessed stage by stage under the new framework, with each technology evaluated separately against the readiness and strategic alignment criteria. The result has been that solar and battery stages of the same development can end up with different outcomes (one stage Gate 2, the other Gate 1), described from the floor as the unwinding of “the dream ticket” of co-located generation and storage, with no clear path to bringing the stages back together commercially.
The panellists were measured and constructive. They repeatedly acknowledged that the principles of connection reform are correct. They want it to work. They were articulating the cost of the transition from a system that everyone agreed was broken to one that hasn’t yet stabilised.
What struck me, and what I want to reflect on here, is what the conversation didn’t quite reach. Not as a criticism of the panel. As an observation about what becomes harder to see when an entire industry is operating under this kind of pressure.
How early-stage decisions shape lifecycle outcomes
ARMSA Academy’s Decision Context Model is a framework for thinking about how early-stage decisions in renewable energy projects connect to outcomes across the lifecycle. It looks like this:
The leverage points sit toward the wider, earlier end of the model, where decisions can still optimise for effective, efficient and safe outcomes together. As projects move along the model, that capacity diminishes. By the narrow end, the cone has resolved into outcomes: hazard observations, incidents, accidents, and in the worst case, fatalities.
This article draws on two ARMSA Academy research studies: a qualitative interview study of eight participants (seven developers and one specialist visualisation consultant), conducted March 2026; and a quantitative survey of 33 renewable energy professionals on safety and risk management, 2024.
