AWS work for UK energy: data platforms, real-time operations, modernisation that serves the transition.

A sector being asked to do more with the same data

UK energy is in the middle of a structural shift. Renewable supply is growing faster than the systems that account for it. The smart meter rollout is generating data at a tempo most retail platforms were never built to handle. Settlement is reforming. Grid operators are publishing real-time data that downstream players need to consume and act on. ESG and emissions reporting cycles are tightening.

Each of those pressures sits on your data layer. The platforms that ran your business well at lower data volumes and slower tempos now need to do more, faster, with cleaner inputs.

Within Energy, the third-party-intermediary (TPI) sub-vertical (energy procurement, broking, and net-zero advisory) is a named D55 sub-specialism. Our anchor client is Amber Energy, a B Corp TPI in Cardiff, where the work was an event-driven Salesforce-to-payments integration on AWS using EventBridge and Lambda. If you're a TPI, that's the closest comparison we'll bring to your conversation.

Where the complexity shows up

Real-time data requirements that your legacy systems can't meet. Overnight batch reporting cycles that no longer match a business operating on real-time wholesale prices and half-hourly settlement.

Customer-facing platforms expected to be as good as consumer apps. Self-service portals, live consumption views, account changes processed without overnight delay.

Integration with the wider data network. Grid operator feeds, smart meter data, weather APIs, third-party services for tariff optimisation.

Regulatory and ESG reporting that has to be both auditable and fast. The same numbers used in your commercial decisions need to stand up in regulatory and investor reporting.

How we think about this sector

Your data layer is where the gain comes from. Get the data right and the rest of the capability stack becomes possible: real-time operational visibility, customer-facing services that match consumer expectations, ESG reporting that lands clean, AI and analytics that produce decisions your business will trust.

Real-time, event-driven architecture is the default shape for energy work. The half-hourly settlement world doesn't fit overnight batch; event-driven AWS architectures on services like EventBridge, Step Functions, and Lambda are the right shape for the work.

What we bring to the energy sector

Central data platforms for energy operations

Single source of truth on AWS for the customer, consumption, generation, and operational data your business runs on. Built so the platform can carry your next phase (analytics, AI, customer-facing data services) rather than just tidy up today's reporting.

Migration from batch to event-driven processing

Re-architecture of your legacy batch platforms into asynchronous, event-driven services on AWS. The pattern fits retail energy suppliers, heat network operators, generation businesses, and TPIs whose data tempo has outpaced the original architecture.

Customer and consumption data unification

Salesforce, billing platforms, payments stacks, and operational systems brought together into a unified data layer.

Capability transfer to in-house engineering teams

Joint build models where your team finishes the engagement equipped to own and evolve the platform.

In practice

Bryt Energy, a 100 per cent renewable commercial supplier, consolidated a fragmented SaaS estate into a central data platform on AWS, with intelligent data pipelines on AWS Step Functions and Lambda feeding a single data lake. Adrian Hobbins, CTO at Bryt Energy: "D55 has been transformative for our business."

Amber Energy, a B Corp TPI in Cardiff, replaced a manual integration between Salesforce and its payments stack with a real-time, event-driven bridge on AWS EventBridge and Lambda.

Switch2, the UK's most experienced provider of end-to-end heat network solutions, modernised a legacy on-premises estate to AWS as a joint build with the in-house team. Re-architected from overnight batch into asynchronous, event-driven services on Amazon ECS.

ENSEK, utilities billing and customer management technology, worked with D55 on application development. Arran Stevenson, Director of Architecture: "D55 have proved to be an excellent development partner."
