The United Kingdom has taken a decisive step toward its energy transition. Starting today, energy generation and demand projects with a valid grid connection agreement can submit evidence to be prioritized under the newly reformed grid connection system. The submission window, open until 29 July, marks the launch of the Connection Reform—a radical overhaul aimed at easing congestion and facilitating grid access for shovel-ready clean energy projects such as solar and wind farms.

With a connection queue exceeding 738 GW—four times the capacity required to meet the UK’s Clean Energy 2030 targets—the reform replaces the previous first-come, first-served system, which allowed speculative and often unviable projects to delay progress. The new process gives priority to ventures that are both technically ready and strategically aligned with national energy goals.

“This is a pivotal moment in the once-in-a-generation transformation of our electricity grid,” said Kayte O'Neill, Chief Operating Officer at NESO. “Developers of critical projects will now have the certainty they need to support investment decisions, while consumers—from homes to hospitals—can rely on a cleaner, more stable energy supply for the future.”

Projects that meet the assessment criteria will move into what’s known as “Gate 2,” receiving a confirmed offer with updated connection dates and site-specific conditions. Projects that don’t meet the readiness or strategic criteria will fall under “Gate 1,” receiving a provisional offer and the opportunity to reapply in future biannual calls.

For energy leaders like Energy Minister Michael Shanks, the reform is essential to achieving 2030 targets: “Today marks a milestone in our work to revamp the connection queue and fast-track clean energy projects that are ready to go. It’s part of our Change Plan to reduce the UK’s dependence on volatile fossil fuel markets and bring down bills for good.”

Jack Presley Abbott, Deputy Director of Strategic Planning and Connections at Ofgem, emphasized the economic and social impact: “By cutting red tape and accelerating ready-to-build clean energy projects, this reform will enable faster connections for key services like housing, hospitals, EV charging stations, and emerging industries like data centers—driving growth across the country.”

The focus on renewable projects is not only a climate imperative—it’s also an economic one. According to UK government estimates, the new system could unlock up to £40 billion annually in private investment for local clean energy.

To help applicants navigate the process, NESO has published a Connection Reform Evidence Handbook and hosted a series of webinars with clear submission guidance. The goal is to ensure a fair and transparent process for all.

Starting in September, project developers will begin receiving updates on their status in the reformed connection queue. Revised connection offers will begin rolling out in the autumn, prioritizing projects with target connection dates in 2026 and 2027. The aim is to finalize all offers necessary to meet the 2030 clean energy target by early 2026.
