Scotland carries almost all of that burden. According to the research findings, 98% of the curtailed output came from Scotland.
The cause is geography plus wiring. Scottish wind capacity has grown faster than the transmission lines needed to carry power south to England, where demand is highest.
So grid operators end up running a two-sided bill. They compensate Scottish wind farms for staying idle while compensating gas-fired stations further south for ramping up.
The trend is moving in the wrong direction. The value of wind curtailment in Britain rose 91% year over year, per the research findings.
Why the BPI thinks miners fit the gap
The report casts Bitcoin miners as buyers of last resort. They can soak up power that would otherwise go unused, and they don’t need it delivered anywhere.
The key selling point is flexibility. Mining rigs can ramp consumption up or down quickly based on how much energy is available.
That sets them apart from what the report calls firm loads, such as AI data centers. Those facilities need steady, uninterrupted power, which makes them a poor match for a supply that comes and goes with the weather.
A separate modeling analysis from May 2026 put some figures on the idea. It found that a 20 MW mining operation sitting alongside a 100 MW wind farm could use 83% of the farm’s curtailed energy.
The same analysis estimated this setup could lift overall system revenue by 32%. It also showed the wind farm’s effective capacity factor rising from 29% to 32%.
The catch: banks and tax rules
The report doesn’t stop at the energy argument. It also flags obstacles that could keep Britain from becoming a serious Bitcoin hub.
Banking restrictions top the list. The report also points to inconsistent investment and tax rules as a drag on competitiveness.
That tension is notable because Britain’s legal footing is relatively strong. The research findings note that Bitcoin has legal recognition as property in the UK.
Background: a growing UK conversation
Bitcoin Policy UK has also published several papers and podcasts on the topic. Their focus has been on mining as a source of demand-side flexibility for the grid and as a tool to support renewable energy targets.
The mining-for-curtailment argument isn’t new globally. What makes the Scottish case stand out is how concentrated the waste is, with nearly all of Britain’s curtailment piling up in one region behind one set of transmission bottlenecks.
