German Intraday Cap/Floor Futures


More and more renewable power is being fed into the German electricity system:

  • Volatile electricity generation causes increased demand for flexibility on short-term power markets – most often accompanied by peak prices.
  • Renewables have low marginal costs causing lower market prices.
  • Low day-ahead prices drive conventional power plants out of the market.
  • This requires suitable hedging instruments for both renewables and conventional power plant operators.


The German Intraday Cap/Floor Future are the first of EEX’s Energiewende products. They allow trading participants to trade positive and negative price spikes on the German intraday market up to four weeks in advance. The underlying is a newly developed price index (ID3-Price) for the intraday market that captures the scarcity/surplus price signal emerging in the last few hours before delivery.

EEX's Cap and Floor Futures are cash-settled derivative contracts with which EEX establishes explicit price references for flexibility on the German Power market.

Since autumn 2016, the price level above which the Cap Future covers exposure has been set at 40 €/MWh. This threshold (“Cap”) indicates the price above which the buyer of a Cap Future receives a payment from the seller for an hourly product traded on the German intraday market of EPEX SPOT. The payment is the difference between the market price, measured by the ID3-Price, and the value of the cap. The ID3-Price is calculated on a daily basis for all delivery hours on the German intraday market and published by EPEX SPOT.

In contrast to the German Intraday Cap Future, the new German Intraday Floor Future allows market participants to actively manage intraday market price risk in the low-price segment and, in particular, negative prices. The threshold below which the Floor Future covers price risk is set at 10 €/MWh.

Defining suitable Caps and Floors

In specifying the payment threshold of € 40 per MWh, EEX has analysed the historical day-ahead prices from 2014. The adjusted threshold of € 40 per MWh is based on the 85% quantile of the ID3-Prices index from 2015. Similarly, the Floor of 10 €/MWh corresponds to the 5% quantile of the ID3-Prices in the same period.

With the chosen thresholds, it is ensured that the German Intraday Cap and Floor Futures only capture hours with high  or low prices on the intraday market, respectively, while at the same time guaranteeing a non-zero payout at settlement as often as possible.
