Platts launches weekly country-specific power Guarantees of Origin spot differential assessments, July 16

Platts, part of S&P Global Energy, has launched three power Guarantees of Origin (GOs) spot differential assessments for Germany, the Netherlands and Austria, effective July 16, 2026.

The markets are assessed as a differential to the widely traded AIB GOs and could be at a premium or discount.

Platts initially proposed the above assessments in a subscriber note published June 1, and announced the launch in a decision note published June 18.

The launch responds to market feedback calling for greater price transparency and more granularity in country-specific GOs markets in Europe. The assessments also complement Platts ' existing offerings in the European GOs markets, including AIB Wind, AIB Solar and Nordic Hydro assessments.

The assessments reflect the differential for current-year certificates and reflect all technologies.

Platts has launched the following assessments:

The assessments reflect the following specifications:

• Volume: Minimum volume 5 gigawatt-hours
• Vintage: Current-year, rolling on Jan. 1 in line with AIB EuGOs assessment
• Technology: Wind, Solar, Hydro
• Pricing unit: Euro/megawatt-hour
• Frequency: Weekly, every Thursday
• Timestamp: 1630 pm London close

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