Sales process

Based on the current planning horizon, contracts can be concluded through Storage Year 2031 (SY31).

Market participants interested in storage services beyond this planning horizon are also welcome to contact our Commercial Advisors for exploratory discussions regarding future storage requirements and potential long-term solutions.

To better meet the needs of our diverse customer base, EnergyStock offers a range of storage services designed to support different flexibility requirements.

For market participants seeking maximum flexibility, our firm Hourly Flex services enable unlimited renominations and profiled nominations within the day. These services provide a fixed capacity ratio and capacity curves combined with a variable working gas volume:

• Storage injection: 0.67 MWh/h
• Injection curve: 24 hours/day
• Storage withdrawal: 1.00 MWh/h
• Withdrawal curve: 16 hours/day
• Working gas volume: 1–480 MWh

Hourly Flex services are designed for multi-cycle use and are available 24/7 on both TTF and Flange. The service includes limited short lead time rights of 35 minutes on TTF and 30 minutes on Flange, providing market parties with significant within-day flexibility.

EnergyStock offers one-year Hourly Flex services for the upcoming storage year as well as for any subsequent storage year. In addition, multi-year Hourly Flex services are available with contract durations of up to five years.

Our firm Trading Services are designed to create value through tradable storage products.

The service supports day-ahead nominations with a flat intra-day profile. Both injection and withdrawal capacity can be utilized throughout the day. Trading services are available on TTF.

Trading services are offered through auctions on the PRISMA platform. EnergyStock may organize auctions during the current storage year as well as for future storage years, providing market parties with opportunities to secure additional flexibility as market conditions evolve.
