Matched Energy partners with IB1 to unlock access to connected clean power data

Matched Energy is joining Open Energy, providing its temporal matching expertise and market-wide access to its ‘Clean Power Index’ to put vital information into the hands of energy consumers. Building on this, the index will immediately be explored by Perseus as a potential supporting model for accurate, harmonised calculations for SMEs.

SME decarbonisation depends on better data

Accurate Scope 2 emissions data—the indirect emissions from purchased electricity—sit at the heart of SME decarbonisation and green financing decisions. But most Scope 2 calculations rely on crude annual accounting that masks the reality of how electricity grids actually work.

What’s more, electricity demand and renewable generation don’t align neatly across a calendar year – they shift hour by hour. An SME might be using an energy tariff that’s marketed as “100% renewable” on an annual basis while consuming fossil fuel power during winter evenings when solar isn’t generating. That gap matters for real decarbonisation, and it matters for lenders assessing genuine progress toward Net Zero.

Making clean power visible

Matched Energy is an independent, not-for-profit energy transparency initiative. It analyses publicly available data using a peer-reviewed methodology to calculate how well renewable supply aligns with consumption on a half-hourly basis—the finest granularity supported by UK electricity settlement systems.

Their groundbreaking Clean Power Index published on October 27th, puts vital information in the hands of consumers. The index underscores the need for regulatory reform of the existing opaque rules that allow suppliers to make misleading “100% renewable” marketing claims.

This level of precision transforms Scope 2 accounting from an annual figure into something actionable: SMEs can see when they’re actually getting clean power, and lenders can assess the physical reality behind carbon claims.

Open Energy & Perseus

Open Energy is creating a connected web of energy data while Perseus is automating sustainability reporting for UK SMEs in order to unlock access to green finance. At its core, Perseus makes it easy to share accurate, assurable emissions data that sits behind carbon calculations—enabling better analysis, action and impact.

Through this collaboration half-hourly renewable matching data will be integrated with carbon accounting platforms and other interested parties across the ecosystem. It will enable SMEs and their stakeholders to access more granular, assurable data about electricity consumption and its true carbon intensity.

By connecting Matched Energy’s temporal analysis to Perseus’s data infrastructure, we’re creating pathways for carbon accountants, lenders, and corporate energy buyers to make better-informed decisions based on the physical reality of the grid.
