Full-stack energy geek — a nominative-determinist energy economist (no deed poll required) with a hybrid tech background, an optimisation obsession, an electrification passion, and a net-zero LinkedIn-dad habit.

People keep asking me how hard it is to predict what the grid will do. The harder questions are what it did yesterday, and whether a megawatt-hour made in Caithness is the same thing as one made in Kent. Part two of what demand means on the GB grid.
'Heat or eat' is back, and No.10's answer is a block tariff. Something bolder: Great British Energy installs the heat pump against the value of the home — and guarantees warmth for life.
Britain publishes several numbers for how much electricity it is using. None of them measures quite what you would think, and a growing share of what they describe is no longer measured at all.
Or cheap rent / grid queue jumping? What does storage really want from Britain's solar farms?
GB wind and solar both set year-to-date records in 2026. Counting them properly means adding back embedded generation, adding back curtailment, and not trusting the series most people reach for.
Britain's contracts for difference paid out £1.37bn in the first half of 2026. The average tells you almost nothing about any of it.
A request for comments, before I write any code: one rule to make a home battery a good grid citizen
Reservoirs are near decade lows in the Nordics and decade highs in Iberia — 2026 is 2022 turned upside down, and prices are following the water
When the frequency broke on 23 June, demand was running above NESO's forecast. Air conditioning and AI cooling were blamed — five summers of settlement data show where/what the cooling load is, and whether climate change is accelerating its impact
Plug-in solar is finally legal — and still the wrong thing to buy. The battery is the story, and it's waiting on the regulator, not the engineers.
The grid was built to flow top-down. In the countryside it's started flowing bottom-up — and that's what the operator now has to forecast.
