About Enwex

What is Enwex?
Enwex stands for Energy Weather Index. So far there is a set of more than 50 single indices for several countries and weather parameters, enabling the energy sector to mitigate volume risks in gas and power markets.

Enwex indices are created to standardize weather into countrywide means, following a transparent and scalable methodology. This enables markets to trade volume related products for wind, solar and temperature or (as weighted averages with power prices), to trade market values.

Enwex based trading products allow you to hedge against volatile renewable volumes and to trade standardized PPAs (Pay-as-Indexed).

Where to trade Enwex? 
Enwex volume indices actually can be traded at Abaxx exchange and at the OTC platform Enmacc. Enwex can also be chosen as underlying for bilateral contracts or via brokers. Just use the contact button in the upper right of this site and we will inform you on everything needed.

 Methodology

Enwex (Energy Weather Index) provides the methodology to transfer weather data into standardized prices, enabling the energy sector to mitigate volume risks in gas and power markets. Enwex‘ focus is on being transparent, scalable and the best compromise between reduced complexity vs accuracy.
As the volatility of renewable energy production grows, we offer „Weather Derivatives 2.0“ – a globally scalable concept that allows for precise hedging of power, gas, and PPA positions. We calculate hourly indices for temperature, wind, and solar based on spatial weights per country. By converting meteorological data into a price format (e.g., utilizing day-ahead settlement), we enable market participants to handle:
– Volume Risk Management: Offset weather anomalies or curtailments.
– Pay-as-Indexed PPAs: Trade renewable assets like baseload contracts.
– Gas Demand Hedging: Demand representation e.g. for TTF, JKM, Henry Hub.
– Trading & Reach: Our indices cover Europe, USA (ERCOT, PJM), Australia and Asia.
Turn weather into a managed asset – with Enwex.
