Operations for SSO


innogy Gas Storage NWE GmbH (iGSNWE) is a gas storage provider in the northwest European gas market who aims to offer its customers flexible and customized products and services. With natural gas storage facilities at five locations in Germany, innogy lines up competitively with other European storage providers.


To take better advantage of market opportunities and gain a competitive edge, innogy decided to consolidate the two caverns storage Epe H-Gas and Xanten into a single storage facility in terms of marketing and to set up a storage pool. This unique feature is meant to enhance operational potentials and offer customers even more reliable storage with an absolute minimum of maintenance times.

The Chal­len­ge

The joi­ning of the two phy­si­cal na­tu­ral gas sto­r­a­ge fa­ci­li­ties, Epe H-Gas and Xan­ten, along with the ran­ge of ser­vices and pro­ducts made pos­si­ble by it, re­qui­red ad­di­tio­nal op­ti­miza­t­i­on of ope­ra­tio­nal pro­ces­ses and avail­a­bi­li­ty of the­se sto­ra­ges.

The com­plex chal­len­ges cal­led for ex­ten­si­ve re­struc­tu­ring of our no­mi­na­ti­on ma­nage­ment, contract ma­nage­ment and cust­o­m­er por­tal. In ad­di­ti­on to the busi­ness re­qui­re­ments that are ent­ai­led with joi­ning the­se sto­r­a­ge fa­ci­li­ties, we have also ad­ap­ted our mar­ket com­mu­ni­ca­ti­on to the AS2/​AS4 stan­dards.

Along­s­ide the tech­ni­cal re­qui­re­ments, the new tran­sac­tion sys­tem is meant to si­gni­fi­cant­ly re­du­ce cur­rent IT costs whi­le also en­ab­ling the grea­test pos­si­ble sca­la­bi­li­ty and fu­ture se­cu­ri­ty. For this re­a­son im­ple­men­ta­ti­on at all le­vels is being rea­li­zed in the Ama­zon cloud (AWS).

Due to the al­lot­ted pro­ject ti­me­li­ne of only nine months and the geo­gra­phic se­pa­ra­ti­on of team mem­bers in Dort­mund, Pra­gue and Leip­zig, ef­fi­ci­ent pro­ject ma­nage­ment du­ring all pro­ject pha­ses was key to suc­cess­ful­ly re­pla­c­ing the exis­ting sys­tem.

The Solution

By choo­sing EXXETA GmbH (EXXETA) and EXXETA Ope­ra­ti­ons So­lu­ti­on for SSO du­ring a com­plex ten­der pro­ce­du­re in 2016, in­no­gy de­ci­ded to go with an in­no­va­ti­ve and ex­pe­ri­en­ced part­ner.

To­ge­ther with the tech­ni­cal de­part­ments in Dort­mund and Pra­gue, it was pos­si­ble to meet the dead­line for swit­ching from the exis­ting sys­tems for contract ma­nage­ment, no­mi­na­ti­on ma­nage­ment, the cust­o­m­er por­tal and mar­ket com­mu­ni­ca­ti­on. As a re­sult of EXXETA’s ex­ten­si­ve and mar­ket-spe­ci­fic ex­per­ti­se, spe­cial ca­ses in the iGSNWE port­fo­lio were ac­com­mo­da­ted and a gre­at de­gree of tran­sac­tion au­to­ma­ti­on rea­li­zed.

The main fo­cus was on op­ti­mi­zing the new sto­r­a­ge pool, inn­EX­pool, con­sis­ting of two se­pa­ra­te sto­r­a­ge fa­ci­li­ties. In com­p­li­an­ce with mi­ning re­gu­la­ti­ons, the fol­lo­wing goals have been rea­li­zed:

  • Increasing the degree of utilization of storage assets;
  • Cost optimization of the compressor operation through optimal utilization;
  • Integration of a cavern simulation based on mathematical models to optimize the virtual storage characteristics.

The new tran­sac­tion sys­tem, which has been in ope­ra­ti­on sin­ce April 1, 2017, af­ter go­ing live wi­thout any com­pli­ca­ti­ons, enables the pro­vi­si­on of fle­xi­ble pro­ducts for the cust­o­m­ers of iGSNWE and cont­ri­bu­tes po­si­tive­ly, in co­ope­ra­ti­on with the ent­ry and exits points, to sta­bi­li­ty and fle­xi­bi­li­ty in the Thys­sen­gas net­work.
