The Challenge: Speed, Scale, and Accuracy
Traditional pricing engines often rely on SQL databases and fixed infrastructure. This approach:
- Struggles to handle millions of complex calculations quickly.
- Is costly to maintain when workloads spike.
- Lacks the traceability and auditability needed for regulatory compliance.
For one UK-based cloud-native energy platform, these challenges were preventing them from delivering instant, competitive prices to customers — especially in B2B scenarios.
Our AWS-Powered Solution
D55 designed a highly scalable, serverless pricing engine that uses AWS services to deliver speed, efficiency, and transparency:
- AWS Lambda – Scales automatically to process 200M+ pricing calculations when needed, with no cost when idle.
- AWS Step Functions – Orchestrates calculations based on inputs, ensuring every step is traceable.
- Full Auditability – Every calculation is logged, enabling compliance and customer confidence.
he result? Real-time pricing for both residential and complex B2B energy customers, without the bottlenecks or high running costs of traditional systems.
Why AWS for Energy Pricing?
- Elastic Scalability – Handle seasonal or market-driven spikes without over-provisioning.
- Cost Efficiency – Pay only for the compute you use.
- Traceability & Compliance – Maintain full visibility into how each price is calculated.
- Innovation Ready – AWS enables quick deployment of new pricing models and features.
Case Study: Delivering 200M+ Calculations On-Demand
A UK-based energy SaaS provider wanted to outperform slow, expensive commercial pricing engines. With D55’s AWS expertise, they now:
- Deliver tariffs in seconds instead of hours.
- Process hundreds of millions of calculations during peak periods.
- Maintain a fully auditable pricing process.
This transformation allowed them to offer more competitive, flexible pricing models — a major advantage in a crowded energy market.
Future-Proofing Energy Platforms
Energy markets will only grow more complex, with new tariffs, renewable integration, and regulatory changes. A modern AWS-based architecture ensures:
- Rapid adaptation to market changes.
- Easy scaling for new customer types or geographies.
- Integration with AI/ML for forecasting and optimisation.
