Why renewables
The environmental case is obvious, and the commercial case is just as strong but less often made.
Once a renewable asset is built, its fuel is free. Water, wind and sunlight don’t have a commodity price, which means the cost of generation is dominated by capital already spent. Buy that power directly before network charges and supplier margin are layered on, and a consumer could be paying something close to the UK’s floor price of electricity.
For compute-intensive workloads, AI training, HPC, rendering, and simulation, electricity is the highest operating cost there is. And by anchoring it to renewable generation, it is the single biggest lever on the economics of the facility.
Hydro: the foundation
Scotland’s hydro abundance is the starting point for everything we do. These are proven assets, many of them generating for decades, in locations with land, cooling water and grid-independent potential.
Hydro’s defining quality is steadiness and flexibility. Storage schemes generate around the clock, day and night, summer and winter. That baseload character maps directly onto compute workloads that never switch off, which is why hydro sits at the core of every site we develop.
Onshore wind: scale and strength
Scotland has some of the best onshore wind resources in Europe, and much of it sits in exactly the kinds of locations we develop: rural, spacious, and far from the constrained parts of the transmission network.
Wind brings scale. A single modern turbine can produce several megawatts, and the Highlands’ wind profile is strongest through the winter months – precisely when solar contributes least. Paired with hydro and storage behind a private wire, wind extends a site’s capacity well beyond what water alone can support.
It also brings an uncomfortable fact about the current system, which works in our clients’ favour. Scottish wind farms are regularly paid to switch off because the grid can’t carry their output south. Co-locating demand next to that generation puts curtailed energy to work instead of wasting it
Solar: the quiet complement
Solar in Scotland raises questions but it can raise output. Panel costs have fallen so far that even at northern latitudes, ground-mounted solar earns its place, particularly through the long daylight hours of a Highland summer, when hydro flows are at their lowest.
That seasonal mirror is the point. Solar peaks when hydro dips. It will not be the key technology on one of our sites, but as part of a blended supply, it smooths the year-round generation profile and lowers the average cost of every kilowatt-hour delivered.
Battery storage: turning variable into dependable
BESS – battery energy storage – is the technology that ties the others together. Batteries move energy through time: charging when the wind is up, or the sun is out, discharging when generation dips below what the data hall is drawing.
On a private wire site that does two jobs at once. It firms the supply, so compute runs uninterrupted on renewable power rather than falling back on diesel or grid import. And it captures energy that would otherwise be lost, raising the usable yield of every generator on site.
The result is a reliable renewable supply.
