GB Power Demand

Near-real-time Great Britain national electricity demand outturn from the Elexon Insights (BMRS) open API: 5-minute MW readings sorted oldest to newest (default: last 24h = 288 points), plus a 'latest' field with the most recent value. ?last=N (1-500) sets how many recent points to return, e.g. ?last=12 = last hour. Upstream updates every ~5 min; served with a 5-min cache.
