Platts launches additional non-biomass UK REGOs assessments

Platts, part of S&P Global Energy, has launched two additional non-biomass UK Renewable Guarantees of Origin price assessments, effective Aug. 24, 2026.

Platts initially proposed this launch via a subscriber note published July 3, followed by a decision note published July 20 .

This is in response to market feedback calling for greater price transparency on later Compliance Periods (CPs) for UK REGOs. The assessments complement Platts' existing offerings in the UK REGOs market, including non-bio and bio current CP to CP02 assessments.

The assessments reflect non-biomass UK REGOs for CP03 and CP04.

Platts rolls the compliance period reflected in its UK REGO assessments July 2 to reflect the trading of REGOs until they are counted by Ofgem for the Fuel Mix Disclosure -- the main use of these certificates.

From Aug. 24, 2026 to July 1, 2027, Platts will assess the following compliance periods:

• Compliance period+3 REGOs: CP28
• Compliance period+4 REGOs: CP29

Platts has launched the following assessments:

The assessments have the following specifications:

• Volume: Minimum volume 5 GWh
• Vintage: The Compliance Period for REGOs rolls over on July 2 each year. In terms of the production period, Platts takes into account REGOs produced from April 1 of the current year to March 31 of the following year.
• Technology: Non-biomass technologies, typically wind, solar, and hydro REGOs.
• Pricing unit: GBP/MWh, along with a Eur/MWh conversion
• Frequency: Daily
• Timestamp: 4:30 pm London close
• Holiday Calendar: UK holiday calendar.

These daily assessments are published in the REC Daily and European Power Daily.
