kwh.dev is a specialist engineering studio designing the data, automation, and AI foundations that power Vester — and the next generation of energy businesses.
Half-hourly settlement, complex tariffs, distributed generation, flexible demand, regulatory pressure, and AI-driven optimisation have fundamentally changed what “energy software” means.Point solutions and bolt-on tools no longer work.kwh.dev exists to design systems that treat energy as the complex, data-rich, operational domain it actually is.
Energy data platforms
Metering, tariffs, bills, and asset data unified into a coherent domain model.Workflow automation
From bill ingestion to optimisation to customer action — without manual glue.AI-assisted analysis
Turning messy energy data into decisions, not dashboards.
Internal tools
Admin, operations, and decision systems built for real users, not demos.Integration layers
Suppliers, brokers, installers, CRMs, finance, and compliance systems.Simulation and modelling
Tariffs, batteries, solar, EVs, demand response, and future scenarios.
We start with the domain model
We optimise for automation, not headcount
We design for AI leverage from day one
We favour boring, proven infrastructure
We avoid premature complexity
We document decisions so systems can evolve
kwh.dev is the technical backroom for Vester — building the platforms that support energy insight, optimisation, and operations at scale.We occasionally collaborate with closely aligned partners where the problem space overlaps, but we are not a general-purpose development shop.
We choose technology based on longevity, operational simplicity, integration friendliness, and AI compatibility.Tools change. Models endure.Data-first. Automation-first. AI-native where it matters.
