Handling Complex Energy Pricing at Scale with AWS

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:

1. AWS Lambda – Scales automatically to process 200M+ pricing calculations when needed, with no cost when idle.
2. AWS Step Functions – Orchestrates calculations based on inputs, ensuring every step is traceable.
3. 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.
