As the UK pushes toward a net-zero electricity grid by 2030, the nation’s power infrastructure faces a pivotal challenge—and real estate is at the center of it. According to new research using Grid IQ by Savills Earth, real estate developments are now caught in a significant grid connection backlog, with 27 GW of demand facing off against 37 GW of capacity—a mismatch that’s not as solvable as it looks.

While national capacity appears sufficient on paper, the grid is fractured: 11% of substations lack the capacity to support new developments, and available energy is often in pockets too small to be useful. This is particularly problematic for housing, with just 500 homes typically requiring 1 MW of power.

The old model—centralized, gas-powered plants delivering electricity one-way to urban hubs—no longer fits a renewable-first future. The UK’s energy landscape is now moving toward a decentralized system powered by solar, wind, and battery storage, but this evolution brings complexities around variability, storage, and behavioral change.

Already, 1.4 million households have adopted rooftop solar, and battery storage is increasingly relied upon to maintain stability during sudden disruptions—such as last October’s Norway-UK link failure, where batteries restored power within seconds.

Still, progress is slow. Grid reform is necessary but risky, with proposals like the CP2030 action plan adding complexity for tech developers. In the meantime, developers must work around long 10–15 year connection timelines, optimizing projects to align with strained grid capacity.

Ultimately, the grid’s future depends on strategic collaboration between government, developers, and tech providers. Real estate isn’t just a power consumer—it’s a critical player in reshaping how the UK generates, stores, and shares energy. The path forward isn’t just about upgrading infrastructure—it’s about redefining how we live, build, and power our communities.
