Estimate your hourly CFE score

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.

Question 1 of 6
Which country is this site or group of sites in?
Question 2 of 6
Which load profile best describes this site or portfolio?
This shapes how your consumption is distributed across the 8,760 hours of the year.
Retail or office – mostly weekday daytime use
Retail or office load profile
Manufacturing – more stable load at night
Manufacturing load profile
Data centre – mostly flat
Data centre load profile
Question 3 of 6

What is a CFE score?

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.

*What you see with this tool is an indicative baseline. For a verified CFE score using your actual meter data and contract terms, explore our
Digital Advisory.

Formula for CFE Score percentage showing sum of Contracted CFE (MWh) and Default Delivered CFE (MWh) divided by Load (MWh), multiplied by 100.

Your CFE score shows you:

01

Your actual emissions picture

02

Cash at risk in unmatched hours

03

Your gap before new Scope 2 rules land

How your CFE score is calculated

Demand: three hourly load shapes – retail/commercial, manufacturing, data centre – using 2024 consumption data
Supply: proxy solar and wind generation profiles, across 8,760 hours. Not project-specific output data
Score: the share of hours where contracted generation covered consumption, volume-weighted across the full year

Your unmatched electricity exposure and price risk

Your unmatched exposure figure is also a financial indicator. In hours where contracted renewable generation such as a PPA doesn't cover your consumption, you're drawing from the grid at spot prices.

The lower your hourly CFE score, the more of your consumption remains price-exposed – regardless of how much you've contracted on an annual basis.
