Custom energy software development
When the systems available on the market do not match your topology, tariff logic, or reporting obligations, we build the ones that do — as a full-cycle engagement or as a dedicated team working inside your setup.
Energy assets generate data faster than most software can act on it. Relevant is an energy software development company building EMS, SCADA-connected monitoring, and analytics platforms that hold under production load — and deploying them without taking your operations offline.



When the systems available on the market do not match your topology, tariff logic, or reporting obligations, we build the ones that do — as a full-cycle engagement or as a dedicated team working inside your setup.

Energy data loses meaning between the substation and the dashboard: mismatched timestamps, duplicated tags, values nobody can reconcile. We connect SCADA, RTUs, meters, historians, ERP, and billing into one flow, with mapping and validation rules that keep every value traceable back to its source.

Decades-old control and billing systems hold your operations together and block every new capability at the same time. We modernize them in phases, refactoring what still earns its place and rebuilding the rest, while the systems stay in service throughout.

Forecasts that miss by a few percent turn into imbalance charges every settlement period, and calendar-based maintenance keeps sending crews to the wrong asset. We train models on your own SCADA, sensor, and market history, and deploy them where an operator can trace each output before acting on it.

Critical infrastructure carries obligations that arrive before the first line of code, and a failed vendor assessment ends a project faster than any technical problem. We design segmented OT/IT boundaries, encrypted device-to-cloud channels, and role-based access, and map ISO 27001, GDPR, and sector requirements into the build from day one.

Your modernization initiative can collapse before it starts if the roadmap ignores what the field can absorb. We assess the systems you run today, sequence the work around operational and regulatory windows, and hand back a costed roadmap in 14 days.

13+ years of migrating live production systems. We refactor first and move in phases, so control rooms keep running while the platform underneath them changes.
246 delivered projects, heavy on IoT and industrial systems. Our energy software integration services connect SCADA, RTUs, meters, and historians at the protocol level, on the terms your field equipment sets.
100+ in-house engineers, 9.8 NPS. Firmware, cloud, data, and front-end under one roof — no subcontracting chain to manage when a device-level issue turns out to be a pipeline issue.
ISO 27001:2022 certified, GDPR covered. Segmented OT/IT boundaries, encrypted device-to-cloud channels, and audit trails that hold up in a regulator’s review.
Up to 50% faster delivery and up to 20% fewer bugs. AI-assisted development accelerates the build; a senior engineer signs off on every line that touches a control path.
96% employee retention, 92% senior engineers. Grid and EMS programs can run two to three years — the engineer who learned your topology in month two is still there at the finish.
We map what you actually run: protocols at the field layer, where data originates, which integrations already exist, and what your maintenance and regulatory windows allow.
Before the architecture is fixed, ISO 27001, GDPR, and sector obligations become concrete requirements: OT/IT segmentation, access model, audit trail, retention periods.
We design the full path from field device to control room — protocol adapters, time-series storage, and the reconciliation rules that keep one value consistent across operations, billing, and reporting.
Work runs in two-week increments, each one demoed on your own data. Every change that touches control, dispatch, or settlement logic passes senior review before it merges.
We replay your historical telemetry through the new system and run it in parallel with production until the numbers agree. QA covers the edge cases your field equipment produces on a bad day, and penetration testing clears the release candidate before deployment.
Cutover happens site by site inside agreed windows, with rollback ready at each step. A team then stays on monitoring, tuning, and the next release.



For over a decade, Relevant has helped energy companies harness the power of technology to optimize operations, improve asset management, and enable smarter decision‑making.


Transform your energy operations with custom software solutions designed to enhance efficiency, cut waste, and support smarter decision-making


We treat the cutover as a separate engineering problem with its own plan.
The new platform first runs in shadow mode: it reads the same inputs as your current system and produces its own outputs, which nobody acts on. Your team compares the two sets of numbers on your own data until they agree, including during peak load and fault conditions. Only then does the first site or asset group switch over, inside a window your operations team defines, with a rollback path tested before the window opens.
What we need from you is the acceptance criteria — which values must match, and within what tolerance. Everything else sits with us: the parallel-run infrastructure, the reconciliation tooling, the rollback rehearsal, and a hypercare period after each cutover where our engineers are on call with your operators.
You own all of it, from the first commit, and the contract says so before development starts.
Repositories can live in your organization from day one, so ownership is a fact of the setup rather than a promise about the final delivery. Everything produced under the agreement transfers to you: source code, infrastructure definitions, CI pipelines, trained models and their training configuration, architecture decision records, and documentation. Your data stays yours throughout, processed under a DPA that names the jurisdictions involved.
Integration starts with an inventory: which system is the authoritative source for each value, how often it updates, and what happens when it reports bad quality.
On the field layer we work with the protocols your equipment already speaks — Modbus, DNP3, IEC 60870-5-104, IEC 61850, OPC UA — through adapters that isolate the rest of the platform from protocol-level detail. Above that sit the systems that carry the same data in different shapes: historians, metering and MDM platforms, ERP, billing, and market interfaces. We map them to one canonical model so a value keeps its meaning as it moves.
Compliance enters the project at discovery, when changing a decision still costs a conversation.
Before the architecture is fixed, we translate your obligations — ISO 27001, GDPR, and the sector requirements that apply to you — into concrete, testable items: network segmentation between OT and IT, the access model, what gets logged, and how long records are kept. Those items go into the backlog with acceptance criteria, so they are verified in every increment.
In the build itself that means encrypted device-to-cloud channels with mutual authentication, role-based access with least privilege, signed firmware and update packages, and audit trails that record who changed what and when. Dependencies are scanned continuously, and a penetration test clears the release candidate before deployment.
Our own delivery process is ISO 27001:2022 certified, which is what your vendor assessment will ask for.
Handover is part of the scope.
Documentation, runbooks, and architecture decision records are written as the system is built, so what your team receives reflects what actually runs. The final phase includes a knowledge transfer period: your engineers work in the codebase with ours, run a release themselves, and handle incidents with our people available rather than in charge. Access, infrastructure ownership, and credentials transfer on a checklist you sign off.
If your goal is to run the platform in-house, tell us at kickoff — we staff the project so your engineers are inside it from the first sprint and our involvement tapers toward the finish. If you would rather keep engineering capacity available, the same team continues on a support arrangement.
