ELIX is a registered trademark of European Energy Exchange AG and EPEX SPOT SE. ELIX is calculated on the basis of aggregated bid and offer curves for every single hour of the day-ahead auction and according to the rules of. For aggregation of bid and offer curves, market areas Germany, Austria, France and Switzerland are taken into account under the assumption of uncongested transmission capacities between those market areas. ELIX is based on the calculation method but not on results of the dayahead auctions and is therefore not based on market prices. ELIX Day Base is the simple average price of the uncongested hourly prices for the hours 1 to 24. ELIX Day Base is calculated for all calendar days of the year. ELIX Day Peak is the simple average price of the uncongested hourly prices for the hours 9 to 20. ELIX Day Peak is calculated for all calendar days of the year.

ELIX Month Base is the simple average (arithmetic mean) of all ELIX Day Base of the month. ELIX Month Peak is the simple average (arithmetic mean) of all ELIX Day Peak for all days Monday to Friday of the month. Page 4

3 INTRADAY CONTINUOUS INDICES 3.1 Hourly Indexes (for Germany/Austria, Switzerland and France) HOURLY INTRADAY CONTINUOUS INDEX The Hourly Intraday Continuous Index is a registered trademark of. The Hourly Intraday Continuous Index is calculated for each delivery day and takes into account trades that occurred on that specific day and on the day before. Cross border trades are taken into account in the calculation of the index. Cross-trades (i.e. trades for which the same counterparty is on the buy and the sell side) are excluded. The Hourly Intraday Continuous Index is based on hourly trades only and block trades are therefore excluded from the calculation. Each hourly Index is a volume-weighted average of the price of all transactions for a certain delivery hour on one specific market area (Germany/Austria, France or Switzerland). The Hourly Intraday Continuous Index Base corresponds to the simple average price of the 24 indices between the Hours 1 to 24 of a specific day on one specific market area (Germany/Austria, France or Switzerland). The Hourly Intraday Continuous Index Peak corresponds to the simple average price of the 12 indices between the Hours 9 to 20 of a specific day on one specific market area (Germany/Austria, France or Switzerland). If no trade has occurred on a specific delivery hour, then the hourly index value is replaced by the EPEX SPOT DAY AHEAD AUCTION price for this specific hour and the concerned market area (Germany/Austria, France or Switzerland)..

3.2 15-minute Indexes (Germany/Austria) 15-MIN INTRADAY CONTINUOUS INDEX The 15-minute Continuous Intraday Index is a registered trademark of. The 15-minute Continuous Intraday Index is calculated for each delivery day and takes into account trades that occurred on that specific day and on the day before. Cross border trades are taken into account in the calculation of the index. Cross-trades (i.e. trades for which the same counterparty is on the buy and the sell side) are excluded. The 15-minute Continuous Intraday Index is based on 15-minute trades only. Each 15-minute Index is a volume-weighted average of the price of all transactions for a certain delivery 15-minute period on one specific market area (Germany/Austria). The 15-minute Continuous Intraday Index Base corresponds to the simple average price of the 24 indices between the Hours 1 to 24 of a specific day on one specific market area (Germany/Austria). The 15-minute Continuous Intraday Index Peak corresponds to the simple average price of the 12 indices between the Hours 9 to 20 of a specific day on one specific market area (Germany/Austria). If no trade has occurred on a specific 15-minute period, we apply an arithmetic rule to match with the Hourly Intraday Continuous Index for this specific 15-minute period on the concerned market area (Germany/Austria). Example: Hour 1 index: 20 /MWh 00:00-00:15 index: 25 /MWh 00:15-00:30 index: 20 /MWh 00:30-00:45 index: 15 /MWh 00:45-01:00: no transactions 00:45-01:00 index calculation: X= 20*4 (25 + 20 +15) = 20 /MWh Page 9
3.3 ID 3 -Price (Germany) ID 3 -Price The ID 3 -Price is a registered trademark of. The ID 3 -Price is calculated for each delivery day and takes into account trades that occurred on that specific day and on the day before. Cross border trades with one leg (Buy/Sell) in Germany are taken into account in the calculation of the index. Cross-trades (i.e. trades for which the same counterparty is on the buy and the sell side) are excluded. The ID 3 -Price is calculated for 15-minute and hourly German products. Each ID 3 -Price is a volume-weighted average of the price of all transactions for a certain delivery period (15-minute or hour) on one specific market area (Germany) over the last three hours before start of delivery of the product. Example: For quarter 21qh1 (delivery from 20:00 to 20:15), the index is the volume-weighted average of all transactions with time stamp between 17.00 and 20.00. If no trades occurred during these last three hours before start of delivery of the product, the averaging window is extended to the whole trading period of the product: For 15-minute products: If no trades at all are present the Intraday Auction value is used If no value are available for the Intraday auction The hourly Intraday value is used For Hourly products: If no trades at all are present the day-ahead auction result is used.
