EPEX SPOT and Speedwell Climate expand their range of Renewable Quanto Indices

Harpenden / Paris, 1 1 May 2023. The European Power Exchange EPEX SPOT and Speedwell Climate have expanded their Renewable Quanto Indices by one new technology, solar, with four new countries covered:

  • Wind Power Quanto Indices are now available for Belgium, France, Germany, and the Netherlands, complementing the existing index for Great Britain - launched in 2022.
  • Solar Power Quanto Indices are available for Belgium, Germany, Great Britain and the Netherlands.

The Renewable Quanto Indices provide an innovative way to manage the risk associated with renewable energy production, combining state-of-the-art modelled solar and wind generation volumes with day-ahead reference prices. They build on Speedwell’s national and regional modelled-volume indices that have been used as the basis of OTC wind power volume-risk contracts for over five years.

These indices are benchmarks that combine renewable energy generation – wind and solar – with spot price fluctuations over a period of time (month, quarter, season, etc.), thus allowing users to transfer risk through OTC market tools to hedge against cannibalisation and shape risk, in particular. Such indices are relevant to renewable energy producers, PPA buyers and sellers, asset holders and investors alike, to ensure stability of revenues, secure their financing and support the development of renewables in the market.

Audited, independent, and reliable index values for financial risk-transfer contracts:

  • Achieved Price: Measure of the actual weighted price received by a wind or solar asset in a specific country per MWh.
  • Achieved Revenues: Measure of the actual revenues generated by a wind or solar asset in a specific country (volume multiplied by market price).
  • Quality Factor: Measure of the ratio of the actual volume-weighted price received by a wind or solar asset in a specific country per MWh relative to the average Baseload price.

A free trial period to access the index suite of delayed feeds is offered until 30 June 2023.

The partners have planned to further develop the index suit according to the needs of market participants.



The European Power Exchange EPEX SPOT SE and its affiliates operate physical short-term electricity markets in Central Western Europe, the United Kingdom, Switzerland, the Nordics and in Poland. Furthermore, EPEX SPOT newly offers local flexibility markets solution and Guarantees of Origin auctions, to foster the integration of renewable energy sources and to enhance the engagement of consumers and producers in the power market.


As part of EEX Group, a group of companies serving international commodity markets, EPEX SPOT is committed to the creation of a pan-European power market. Over 300 members trade electricity on EPEX SPOT. 49% of its equity is held by HGRT, a holding of transmission system operators.
