Provenance Record

Well-structured News piece (692 words). Overview / What We Know / What We Don't Know / Analysis. Correctly frames the decision as a 'minded-to' consultation rather than a final award, and is careful to flag that the list and capacity could still change. Technical depth is appropriate and every claim is attributed inline to a named outlet.

All 5 source snapshots read from disk and verified. source-0 (Ofgem, 200): confirms 'has identified 16 projects creating an LDES portfolio', 'Minded-to-Decision' / provisionally selected, consultation 'open until August 7' (article: '7 August' — same date), 'final determinations expected later this year', 'eight hours or more', floor quote 'If the project's revenue falls below this floor, consumers pay the LDES operator the difference up to the floor level' verbatim, cap quote 'above which projects pay money to consumers if they end up making more than is considered a fair rate of return on invested capital' verbatim, 'geographically spread across Scotland and England, with one proposed VRFB project selected in north Wales', and the Akshay Kaul quote 'This takes us a step closer towards the long-duration energy storage we need in a clean power system to maintain secure supply' verbatim — Kaul title 'Director General for Infrastructure' confirmed. 7,645 MW and the 2.7-7.7 GW range are NOT on the Ofgem page; the article correctly attributes them to Energy-Storage.news. source-1 (Energy-Storage.news, 200): confirms 'projects total 7,645MW of capacity', '8- to 22-hour durations', 'chosen from 77 shortlisted projects totalling 27GW', 'very top end of Ofgem's guided 2.7-7.7GW range', 'majority of capacity is in Northern Scotland', and Field CEO Amit Gudka 'The UK's LDES Cap and Floor is a global landmark scheme' verbatim. source-2 (Water Power Magazine, archive.org fallback, original 200): confirms per-project capacities — Earba 1,800 MW (Gilkes Energy), Coire Glas 1,440 MW (SSE Renewables), Loch Kemp Storage 660 MW near Inverness, three projects 'approximately 87GWh', 50MW TeesCAES CAES, 'lithium-ion battery developments across Scotland, England and the Midlands'. Sum 1,800+1,440+660 = 3,900 MW matches article. Per the brief, these per-project capacities are correctly cited to Water Power Magazine, not the Ofgem landing page. source-3 (Proactive Investors, 200): confirms tech split 'three pumped hydro projects, one compressed air storage scheme and 12 long-duration battery projects, including 11 lithium-ion facilities and one vanadium flow battery', economic-life assumptions '40 years ... 25 years for Li-ion batteries and 30 years for the vanadium flow/zinc battery', and heatwave quote 'Low wind speeds and soaring electricity demand forced gas plants to provide more than half of Britain's electricity on peak days' verbatim. source-4 (Coire Glas, 200): confirms 'Loch Lochy in the Scottish Highlands between Fort William and Inverness', 'at least 45GWh of long duration electricity storage', 'Great Britain's largest energy storage project if delivered' verbatim.

All 16 projects / 7,645 MW total, the 3/1/12 technology split, the three flagship pumped-hydro schemes with their exact capacities and developers, the consultation dates, and the 'minded-to' (not final) framing each trace to a cited source. No fabricated project names. renews.biz (which returned 403 in research) is not cited. No orphan URLs — all 5 inline body links are present in article.sources.
