While Ofgem classifies biomass as renewable, many consumers prefer zero-emission sources like wind and solar. However, when we looked at Ofgem's REGO database, we've found over 15% of generators classified as "biomass" appear to be misclassified (they appear to be biogas/anaerobic digestion, which have very different emissions). This error in the underlying data creates material distortions when we add a biomass filter. To fix this, we're inviting suppliers to submit evidence of misclassifications. All submissions will be published for transparency, and we'll launch the filter by end of February. ⚠️ Request to UK suppliers: If your biomass generators are misclassified in the REGO database, get in touch via contact@matched.energy with evidence of the misclassification before Feb 13th. For full transparency, all submissions will be made public when we release the new filters.

A month after launching the Matched Clean Power Index, we're adding the two most requested features. First: nuclear tracking. Nuclear generated around 40 TWh in 2024, yet none of it is covered by REGOs. Starting today, the Index optionally includes nuclear power. The impact is significant—British Gas jumps 14 places, EDF climbs 12. Several European countries already issue certificates for nuclear. Britain's exclusion is increasingly anomalous given Clean Power 2030 targets. Second: renewable tariff scores. Where available, we now calculate matching scores for renewable tariffs, not just portfolio-wide. So Energy, for example, scores 50% across their entire portfolio but 74% for renewable tariff customers specifically. That 24 percentage point difference matters: it shows renewable tariff customers are getting meaningfully cleaner power than portfolio averages suggest. Both updates are live now.

Great analysis and visualisations from the team at EnergyTag that uses Matched data to compare how renewable each supplier vs the grid mix at that time. If you're a researcher or analyst working on clean energy interested in using our data, get in touch! 📊

Utility Week article on Matched's launch! 🎉 Particularly interesting to see a quote from the Advertising Standards Authority: "When advertisers promote energy from renewable sources, they must not misleadingly imply that the electricity generated from those sources is delivered direct to their customers." Given the Irish equivalent of the ASA has crunched down on misleading "renewable" claims, we'll be following this closely in the UK... Credit to Adam for pulling together perspectives from Uswitch, the Advertising Standards Authority, and Good Energy on why accurate reporting of supplier renewable energy credentials matters.

We admit that what we do is pretty wonky. Hourly renewable matching, settlement data, grid accounting - these are complex topics! But it's fundamental to grid decarbonisation, so explaining it to a generalist reader is important. The Telegraph's coverage of the Matched Clean Power Index launch does exactly this - explaining why current rules let suppliers claim 100% renewable while delivering far less, without sensationalising or downplaying the real progress that some suppliers are making. Coverage like this moves the conversation beyond outdated annual accounting. Honest reporting shows what grid decarbonisation actually requires: storage, flexibility, and generation aligned with demand, not certificates bought in summer to offset winter gas. https://lnkd.in/eN5JASrA

We're partnering with Granular Energy, the SaaS platform helping suppliers build and deliver hourly matching clean energy products. Matched works with public data to show which suppliers are doing hourly matching right. Granular Energy gives suppliers the infrastructure to actually do it. The shift toward hourly matching needs both transparency and tools, and we're glad to be working closely with our friends at Granular to provide this.

Scope 2 carbon accounting needs to catch up with reality. We've partnered with Icebreaker One's Open Energy project to bring temporal matching data into Scope 2 calculations. Their Perseus framework automates SME sustainability reporting for green finance. Our data shows what renewable power consumers actually received—hour by hour, without annualised offsetting: https://lnkd.in/escsBUUD The data infrastructure exists: Elexon publishes half-hourly settlement; NESO tracks generation; Ofgem manages certificates. We connect these sources to calculate half hourly matching scores for every UK supplier. Why now? The GHG Protocol is revising Scope 2 guidance toward hourly accountability. Corporate buyers want suppliers delivering provably clean power throughout the year. SMEs need accurate emissions data to unlock green finance. If you're building carbon accounting tools or managing corporate energy procurement, let's talk about making this data useful: https://lnkd.in/eJ_NTax5

You're paying for 100% renewable electricity. But how much are you actually getting? Today we're launching the Matched Clean Power Index—showing how much renewable power UK suppliers actually deliver, hour by hour: https://lnkd.in/eFQz2Ka4 The problem is that suppliers can claim that summer solar power is being used to cover winter consumption. Your heating on a January evening? Probably fossil fuels, even on a "100% renewable" tariff. This isn't fraud—it's outdated rules from 2003, when renewables were 3% of the grid. Now they're over 50%. The spread is huge. Good Energy is 88% renewable. Octopus achieves 69%. Check what you're getting - we see electricity branded as 100% renewable that is actually only 55%. We combined public data with 30+ experts including Imperial College London to show how well renewable generation aligns with customers' demand, hour by hour. The methodology is open source on our website. Britain aims for Clean Power by 2030. Getting there affordably means investing in renewables and storage that provide electricity when we need it—not playing with outdated rules. How renewable is your supplier?

The full Matched Clean Power Index drops Monday. 25 UK suppliers ranked by hour-by-hour renewable matching. Until then, a challenge: can you identify these suppliers from their consumption and generation profiles? The charts show when renewable power actually meets demand—hour by hour, all year. Notice the seasonal patterns. The daily cycles. The gaps that annual certificates hide. The first supplier should be obvious. Comment or DM your guesses. First correct answer gets early access to the full index.

You're paying for 100% renewable electricity, but it could be as low as 55%. We've built a methodology that reveals what percentage of your electricity is actually renewable—measured half-hour by half-hour, not just averaged across a year. The challenge wasn't the maths. It was connecting three public datasets that have never been linked before: Elexon settlement data, Ofgem's REGO database, and National Grid generation mix. Our full methodology is 25 pages. This is the 5-minute version—no jargon, just the key data sources and calculations: https://lnkd.in/ecwJ8A2W On Monday, we publish the full Matched Clean Power Index.
