Underground gas storages (UGS) represent a unique infrastructure combining reservoir with gas surface facilities. The most important part of variable costs of each storage is fuel consumption for compression work (gas or electricity) for gas injection but also for withdrawal depending on storage characteristics. For increase the efficiency company has to optimize storage dispatching management and install more efficient compressors.
Company storage complex uses 8 entry/exit points, 11 gathering stations, 13 reservoirs, 14 compressors and numerous intersections of pipelines with various pressure levels. In addition, the storage is interconnected with several gas grids. Considering amount of gas injected and withdrawn in storage operation, even savings amounted to a few percent of fuel consumption can lead to significant economic benefits over year. Company needs to optimize processes of gasflow and try to save as much as possible.
To support dispatching in their decision making processes a dedicated Gas Flow Optimization Software was implemented by this company together with software company IPESOFT.
Generally there are two variants of optimization we apply on our storage.
Main functions of the Optimization Software for this company developed together with IPESOFT:
Real results shows that implementation brings both financial and non-financial benefits. Most important benefits are:
For evaluation purposes we decided to use a comparison between results proposed by software and dispatcher's manual control of injection in season 2017. Altogether more than 100 days (scenarios) were evaluated up to date. There are two categories of daily nominations:
Based on this data we can estimate that overall savings achieved by Optimization Software is more than 4%, out of that complex scenarios delivered more than 3%.
Results also show that in almost 20% of scenarios the fuel gas saving was 10% or more, what is quite significant saving potential.
A unique project by energy innovators from Slovakia brings new possibilities for the use of battery storage to our region. In August 2022, it was possible to successfully certify the first battery storage, which, in addition to deviation regulation, can also be used to provide Ancillary services (AS).
Digital transformation in form of MES system implementation brought more efficiency and innovation to a successful industry company
The process of digitization and implementation of information technologies brought increased production efficiency, process optimization and better management decisions based on real-time information.
Advanced optimization of the use of a combination of sources and fuel mix to increase the efficiency of heat and electricity production and reduce the emission load in the Martin heating plant.
