The regulated Energy Derivatives Market in Greece was established in 2020, following the approval of the Hellenic Capital Market Commission. The organization and support of its transactions is realized by the Hellenic Energy Exchange (HEnEx), whereas the clearing, assuming the role of the Central Counterparty, is under the responsibility of ATHEXClear, a company member of the Hellenic Exchanges Group (HELEX).

Derivatives are financial contracts whose value is linked to the value of an underlying asset. They are complex financial instruments, that are used for various purposes, including hedging and offering access to additional assets or markets. The participation in such a market creates new opportunities for the market participants by hedging the risk of fluctuations in electricity power prices or on arbitrage.

HEnEX provides the transparency and the reliability you need to protect against price surges by locking in your future energy costs.

HEnEx’s Derivatives Market offers trading on Futures with financial settlement of the transactions while Members or clients of Members who are also Participants in the Day-Ahead Market can benefit from an optional physical settlement of their monthly contracts. The underlying asset of Futures is based on energy indicators related to the physical spot market. They are calculated based on the baseload profile, which provides a constant energy delivery rate for all hours, Monday to Sunday, and the peakload profile, which provides a constant energy delivery rate from 08:00 to 20:00 CET, Monday to Friday. The duration of the contracts can be monthly, quarterly or yearly.

The tradable contracts are listed below:
