RE100 makes two major changes to its technical criteria

In October 2022, RE100, an international initiative for grid decarbonisation on the global scale, made two major updates to its technical criteria for renewable electricity procured by its members. RE100 has redefined the European market boundary criteria and introduced a 15-year limit on commissioning and repowering dates of power plants from which members source electricity. In addition, RE100 has specified that hydropower should now be sourced “sustainably,” which can be proven through third-party certification.


European market boundary criteria

Claims of renewable electricity use are only valid if the generation and consumption of said electricity occur in the same electricity market. The redefining of European market boundaries is thus highly significant for companies sourcing renewable electricity.

According to the updated technical criteria, a country belongs to the European single market for electricity if it meets the following three conditions:

  • It is in the EU single market
  • It is a member of the Association of Issuing Bodies (AIB)
  • It has a grid connection to at least one other country that meets the above conditions

Exceptions are made for jurisdictions that have very little domestic electricity production and import most of their electricity from countries that meet the updated criteria. This includes the Channel Islands, Andorra, Liechtenstein, Monaco, San Marino, and Vatican City. The list of countries and areas that currently meet these new criteria are:


All European countries that neither fit the new criteria nor are exempt now represent individual markets for renewable electricity.


By this new definition of market boundaries, over 600 GWh of electricity sourced by 46 different RE100 members across 24 countries in 2022 would no longer be eligible to count towards RE100 goals.

This update applies to contracts with operational commencement dates after 1 January 2024.


15-year limit on commissioning and repowering dates


Sustainably sourced hydropower

In addition to these changes, RE100 has clarified existing guidance concerning accepted sources of renewable energy and specified that hydropower should be sourced “sustainably” to be eligible to count towards RE100 goals. RE100 recommends that this be qualified through third-party verification, including (but not limited to) the Green-e® Renewable Energy Standard and the Hydropower Sustainability Council’s Hydropower Sustainability Standard.


Per RE100, the intention behind introducing stricter sourcing criteria for RE100 members is to raise the standard of claims of renewable electricity. In addition, these updates drive grid transformation, which in turn “lower[s] barriers to voluntary procurement of renewable electricity”.
