Answer six questions to get an estimated hourly CFE score for your portfolio – including your unmatched electricity exposure and how different solar and wind mixes affect your coverage. No data upload, no login.
A CFE (Carbon-Free Energy) or hourly matching score is the percentage of your electricity consumption matched by carbon-free generation in the same hour – not across the year.
This is the direction of the ongoing GHG Protocol Scope 2 review, with the full standard expected to land in 2027.

Annual matching checks whether total yearly procurement equals total yearly consumption. It does not check whether generation and demand align in each hour.
A solar PPA generates during daylight; your facilities draw through the night. Every overnight and peak demand hour that exceeds your generation is an unmatched gap. Annual volume may balance to 100% – hourly coverage could sit at 30–70%, higher with wind-heavy portfolios.
A solar-heavy portfolio will also generate excess EACs midday – certificates that carry no hourly value once the score is capped at 100%.
The GHG Protocol Technical Working Group has proposed hourly matching as a quality criterion for market-based Scope 2 claims. Phase 1 consultation closed in late 2025; Phase 2 runs through mid-2026. The final standard is expected in late 2027.
Under the current proposal in review, companies would need to demonstrate hourly – not just annual – alignment between procurement and consumption. Whilst no specific targets are set for the hourly match, your current hourly CFE score shows your position and what procurement steps can help you boost the score.
Technology mix is the more important variable – more so than your load profile type. At 100% annual coverage, a solar-only portfolio could score 30–50% across retail, manufacturing, and data centre profiles. A wind-only portfolio on the same volume scores up to 80%. That is a significant percentage point swing from changing the technology, not the contracted amount.
This estimator uses typical proxy load profiles and modelled generation data relevant for energy buyers in Europe. It gives a directional baseline without requiring any data upload.
For a verified CFE score, we'd need your actual hourly consumption data, your specific contract terms, and real generation records. Renewabl's Digital Advisory team can produce verified hourly CFE scores alongside a data readiness assessment and technology mix recommendations – book a call with them at the bottom of the page.
Unmatched exposure is the share of your consumption not covered by contracted renewable generation in a given hour. In those hours, electricity is drawn from the residual grid mix at prevailing prices.
It is both a reporting gap – hours where production-matched supply doesn't back your Scope 2 claims – and a financial one, since that demand is drawn at spot rates rather than from a contracted PPA position.
