Platts proposes to launch weekly country-specific power Guarantees of Origin spot differential assessments, July 16

Platts, part of S&P Global Energy, proposes to launch three power Guarantees of Origin (GO) spot differential assessments for Germany, the Netherlands and Austria, respectively, effective July 16, 2026.

The markets will be assessed as a differential to the widely traded AIB Guarantees of Origin, and could be at a premium or discount.

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

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

A summary of the proposed assessment launches is provided below:
