about Cambridge

Cambridge draws its electricity from the UK Power Networks distribution network — DNO region A. The answer above is the live carbon-intensity forecast for that region, published every half-hour by the National Energy System Operator. Households across Cambridge share the same regional grid, so the answer is the same whether you're in CB1 or a few outcodes over.

If you're on Octopus Agile, your half-hourly price tracks the same wholesale market that drives carbon intensity in Cambridge's grid. For everyone else on a fixed-rate tariff, the answer is the honest "is now a good time to use power" signal — your bill won't change, but the grid is greener when wind and solar are doing the work.
