In Europe, we can build a data centre in under two years, but the grid reinforcement needed to power it can take five to ten. That (growing) gap is defining the core commercial problem in the sector. It is also, increasingly, a political one.
In Ireland, connections are becoming conditional on developers providing matched generation or storage. In Germany, PUE thresholds and waste heat re-use are mandatory. In Texas, every interconnection request since August 2026 faces a full audit of ownership, financials, water use and community impact; if failed, no grid access is granted. In France, the network operator is offering connections with curtailment into the early 2030s.
This is all to say that communities, regulators and network operators are scrutinising data centre deployment, and asking developers to contribute more to local communities. They are asking developers to be ‘better citizens’ and specifically better ‘grid citizens’.
The answer is not always “more grid”, but instead first ensuring we are using our existing connections properly.
Across the UK colocation sites we analysed, average draw over a year was under 40% of contracted capacity. Connections are sized for peaks that rarely happen and for expansion that has not arrived yet.
What’s worse, the grid itself is getting harder to lean on. Market-provided inertia in the GB grid system has roughly halved since 2017, from a median of 239 GVA-seconds to 126. In 2017, 0.4% of periods fell below the operating threshold. In 2026, 44% did. Data centres add large, fast-moving demand and contribute almost no inertia in return. It is not difficult to see why operators are being asked to bring something to the table.
PoweringAI’s microgrid approach—build better on brownfield powered land.
Imagine an orchestrated microgrid behind the existing grid connection. It combines a grid-reinforcing synchronous condenser with hybrid electrical-thermal energy storage, firm on-site generation with heat recovery, engine heat recovery for cooling, all integrated through a single energy management system.
Individually these setups are well understood, however the real value is in the integration into this “microgrid” concept for data centre build.
The benefits for the local area are a reinforced grid, lower-cost heat for local amenities, minimal water demand, and an anchor investment that can unlock redevelopment in often neglected areas. For the operator, we calculate the benefits as follows:
- Faster time to revenue. Firm generation plus grid-forming assets energise the site on the connection it already has, and expedite new connections as a positive grid citizen, potentially saving two to six years.
- Lower operating costs. Electrical-thermal storage peak-shifts load, a medium-voltage uninterruptible power supply (MV-UPS) lowers losses, and optimised cooling lowers draw, saving approximately 10 million euros/year at 100MW*.
- More sellable megawatts. Hybrid storage smooths power swings, and absorption chillers reduce peak cooling demand, so that the connection can be sized for near-average load. Estimated 1.6 to 2.6x IT load per MVA* increase at a co-location site*. Meaning the same connection can serve significantly more IT capacity.
- A local asset. Grid-forming inertial and fast frequency response comparable to a CCGT plant, closed-loop cooling that displaces most of the heat, and services available to local industry, positioning the data centre as a community asset and easing the path to permitting and grid connection.
So, while grid connection may be the scarcest asset in this industry, operators who optimise it, rather than simply wait for more capacity, will get to revenue faster. Built right, data centres can benefit everyone, including their operators—that is the central thesis of PoweringAI.
