Following the opening of the electricity and gas markets and the creation of new markets like e.g. for CO2 certificates, competition in the supply industry has increased and become more diversified. Energy markets show several peculiarities in that.

Energy consumption and prices are subject to strong, oftentimes hard to predict fluctuations. In addition, other than in classical market situations, as electricity cannot be easily stored, demand can only be regulated to some extent through price. Nevertheless, long-term offers have to be created on short notice, and decisions be taken.

In addition, the supply industry is liable to numerous state regulations, which vary significantly between countries, and are subject to constant modifications. Successful business processes in this field need to be flexibly adjustable as well as engineered under consideration of diverse constraints.

For a large German energy supplier, itestra GmbH has developed a business-critical trading system, which has been used successfully for years and is under constant further development. Competencies in following fields were applied:

• Mathematical models
• Efficient algorithms for time-critical calculations with large data volumes
• Flexibly adjustable software architecture
• Lean development processes in order to decrease time to market
