Clean Power Index launches UK net-zero tariffs for hydrogen & EVs

Welcome to Net Zero News, where we bring you the latest developments driving the UK’s transition to a net-zero future. In a significant step towards greater transparency in energy markets, a new digital platform called the Clean Power Index has officially launched, allowing UK consumers to see exactly how much of their electricity comes from renewable sources in real time.

The Clean Power Index went live on 27 October 2025, following a collaborative effort led by the independent non-profit Energy Transparency Initiative. Net Zero News can reveal that the platform aggregates generation data from the National Grid, Ofgem and participating electricity suppliers to present a clear breakdown of tariff-specific renewable content. Consumers across England, Scotland, Wales and Northern Ireland can now compare how much wind, solar, hydro and bioenergy feed into their chosen energy deals.

Consumers have long struggled to verify green claims made by suppliers amid a complex wholesale market. The Clean Power Index addresses this challenge by offering intuitive graphics and percentage indicators alongside detailed hourly generation mixes. It also highlights the provenance of renewable energy, indicating whether power is sourced domestically or through imported certificates. This innovation aligns with the UK’s target to reach 70 percent renewable electricity generation by 2030 and to achieve a fully decarbonised power sector by 2035.

Why this matters is clear: better visibility on tariff quality is expected to drive consumer switching towards genuinely low-carbon offers, accelerating investment in renewable infrastructure. Net Zero News understands that if just 20 percent of UK households switch to high-renewable percentage tariffs within the next two years, the move could translate to a reduction of up to two million tonnes of CO₂ annually. Increased demand for truly green power is also likely to bolster the business case for new wind and solar projects, directly supporting the government’s ambitions under the British Energy Security Strategy.

The Clean Power Index has secured initial funding of £1.2 million, including a £700,000 grant from the Department for Energy Security and Net Zero and £500,000 from the Clean Growth Fund, a philanthropic initiative promoting low-carbon innovation. Ofgem has provided regulatory guidance, while technology partner GridOptics supplied the data-aggregation software and secure API integration. Major energy suppliers such as Octopus Energy, EDF and Scottish Power have committed to feed live generation data into the platform, with smaller suppliers encouraged to join ahead of the UK’s next price cap review.

This launch forms part of a broader policy drive to embed transparency and accountability into the UK’s net-zero framework. Net Zero News understands this initiative dovetails with the upcoming Electricity Market Reform 2.0 proposals, which aim to incentivise high-integrity renewable tariffs and clamp down on “greenwashing.” It also complements regional strategies such as Scotland’s aim to generate 50 percent of its energy consumption from renewables by 2030 and Wales’s Low Carbon Delivery Plan, which calls for greater transparency in supplier claims.

Across the energy industry and local communities, the Clean Power Index is expected to generate ripple effects. Community energy groups will be able to showcase their contributions more effectively, attracting new investors and members. Consumer rights organisations have welcomed the platform as a tool to hold suppliers to account, while suppliers view it as an opportunity to differentiate their green offerings. Some critics caution that rural areas with less renewable capacity may face higher tariffs, but the platform’s developers say it will also highlight the need for equitable grid investment in underserved regions.

Looking ahead, the Energy Transparency Initiative plans to expand the Clean Power Index to incorporate gas-intensive tariffs, domestic heat pumps and the carbon intensity of neighbourhood grids. A mobile app is due for release in early 2026, while work is already underway to integrate the platform’s data with smart meters and in-home displays. By the end of next year, the Index aims to cover 90 percent of domestic energy accounts, setting a new benchmark for openness in the transition to clean power.
