Forecast accuracy you can check: what site calibration does to GB wind farm error
On the 6 September scorecard, fitting each wind farm's power curve to its own metered output cut forecast error for 64 of 65 GB farms, by a median 42%. Find your farm's numbers in the searchable table.

What cannibalisation does to a battery's debt: the covenant year, not a haircut
A 2027 two-hour battery followed through a fifteen-year tenor at equilibrium: the revenue wedge against today's price shape arrives in the first three years and stays; debt sized on today's prices breaches a 1.10× covenant in year three; debt sized at equilibrium is 25% smaller — 60% on a fast build-out.

Which battery duration to build, given what everyone else has built
One-, two- and four-hour batteries solved jointly at equilibrium across 63 fleet mixes: every cross-effect is negative, own-effects are steepest for four-hour, and the asymmetry has two faces — long duration loses the most pounds to a build, short duration the larger share.

Data centres: the renewables fleet's best customer, the battery fleet's newest competitor
Gigawatts of data-centre load priced at equilibrium: load planned for un-cannibalises wind and solar (solar capture 0.36 → 0.58 at 10 GW, +£1.7bn a year) and fills the troughs batteries charge in (−26% fleet revenue, −38% with half the load flexible) — opposite signs at every penetration we ran.

What is a megawatt of data-centre flexibility worth when ten gigawatts of it exist?
Data-centre flexibility priced at the equilibrium its own scale creates, not at today's prices: the marginal flexible MW loses 62% of its value between 2 and 10 GW, price-taking valuations overstate by 1.15–1.73×, and 10 GW of flexible load takes 21% off GB battery fleet revenue.

One year of measured GB battery revenue: what 6.4 GW actually earned
At least £33.7k/MW·yr, measured from settlement — not modelled. The fleet grew 15%, frequency response saturated, the Balancing Mechanism absorbed the megawatts, and the top quartile out-earned the median by as much as the median itself.

Why I'm Building Compounding Energy: Getting the right answers in time to act
A revenue forecast that treats a battery as a price-taker overstates returns by 100–300% at the fleet Great Britain plans for 2030. Why I founded Compounding Energy — and the standard every product ships to.
