Electricity Auctions
Modernization of legacy energy trading infrastructure
Client: Power Trading Enterprise, Germany
Zero
disruption to existing integrations
~20 years
of integrations and automations preserved
Real-time
market monitoring for faster decisions
Challenge
The legacy auction application could no longer meet the demands of a changed renewable energy market. It had to give way to a third-party tool — without disrupting the integrations and automations built around it over nearly 20 years.
Solution
A cloud-based, service-oriented system in C# that integrates the external solution seamlessly and preserves the existing infrastructure. Clean architecture throughout, with multiple interfaces so everything already talking to the old application keeps working.
Implementation
- 01Functional decoupling into backend services
- 02UI mockups based on the legacy design, for continuity
- 03Isolated development and deployment pipelines
- 04Centralized logging via Azure Application Insights
- 05Real-time communication over WebSockets and Kafka
Business impact
High-frequency algorithmic trading and seamless deal automation
Real-time market monitoring for faster, better-informed decisions
A third-party platform integrated with zero disruption and lower operational risk
A long application lifecycle on a modern stack under continuous maintenance
