GO-LFI is GridOptic's benchmark for annual revenue per MW in GB local flexibility. It converts fragmented published market evidence into a comparable signal, presented as an illustrative band in £/MW/yr. Each cell carries a tier (BENCHMARK, INDICATIVE or INSUFFICIENT); published bands include a 1-to-5 star price-confidence rating. Forward cells also carry a requirement-confidence rating; no band is shown where evidence is insufficient.
Asset teams need a comparable read on local flexibility rates by network, technology, and delivery year. GO-LFI provides this benchmark by assembling and normalising published procurement and dispatch records from all six GB DNOs into a consistent shape, with a GB composite alongside per-DNO cells. It shows what the market is paying, not a specific asset forecast.
GO-LFI is not an offer and does not model asset-specific operating profiles, degradation, efficiency, or market capture, nor does it predict future tender clearing prices. Asset-specific modelling is handled by the Revenue Forecaster, which incorporates operating assumptions and contracted-evidence and downside bands.
Each cell has two components. The availability component annualises contracted fees using paid service-window hours, not a full year. Dispatch revenue is converted to £/MW/yr across fiscal years, ensuring multi-year evidence is not presented as single-year revenue. These are reported separately; their sum is an indicative estimate. Where only a procurement-level utilisation price exists, it is annualised against an empirical activation-hours constant, as a service window indicates availability, not call frequency.
Price and requirement evidence are rated separately due to distinct underwriting risks. Price confidence (1-to-5 stars) derives from the cell tier, diversity evidence (distinct providers or competition breadth), and quality flags. Five stars only at BENCHMARK; one star for INSUFFICIENT or a SUSPECT flag. Requirement confidence (1-to-5 stars), for forward delivery years only, assesses whether a DNO has a stated forward need (natively published or held flat) and whether DFES growth, queue activity and upcoming-need signals corroborate it. A high price rating with a low requirement rating does not mean the revenue is secure.
Read a band with its tier. BENCHMARK cells require at least twenty contracts, one MW, and three distinct providers with no quality flag, the grade at which a number can carry weight in an investment case. INDICATIVE cells meet the evidence floor for screening and comparison but need clear flagging in underwriting. INSUFFICIENT cells, or any with a SUSPECT flag, are withheld; the absence of a number is itself a signal. A one-star price rating indicates insufficient evidence for publication; five stars signify benchmark-grade evidence.
Use GO-LFI for location screening, portfolio comparison, market context, and as an input for the Revenue Forecaster. Use the confidence ratings to weigh evidence before building a case. Do not use a single GO-LFI cell as the sole revenue assumption. Always review its tier, provider count, and quality flag. Do not annualise bands by 8,760 hours, treating INDICATIVE as BENCHMARK, or using historical cells as forward forecasts. Never quote a band without its confidence rating.
The full GO-LFI methodology, including sources, normalisation, annualisation, confidence model, and limitations, is detailed on the methodology page. Review it before relying on a cell. Every figure traces to a published record, with tier and confidence ratings.
