From energy trading to energy technology.

CET Energy is an independent, Switzerland-based technology company. We build AI for load forecasting and AI services for municipal utilities in Germany, France and Switzerland.

Who we are

Independent. Technical. Disciplined.

CET Energy combines deep energy-market expertise with proprietary AI and machine learning.

We help municipal utilities forecast consumption more accurately and put AI to work across their operations. Our models and infrastructure are designed, built and operated in-house.

We offer our services through two brands: CetAI for Germany and France, and TekAI for Switzerland.

Our story

How we became a technology company.

Our path from a power trading firm to an AI technology company.

01 · Origins
A power trading firm in Lutry
CET Energy began as a specialist power trading firm, trading day-ahead and intraday power systematically across several European markets.
02 · Building
Technology built in-house
To trade well, we built our own AI and machine-learning infrastructure: forecasting models for load, renewables and prices, data pipelines and real-time systems. Over time, this technology became the core of the company.
03 · Turning point
More potential in AI
We saw that our AI development had more potential than trading itself. We decided to discontinue power trading and to restructure CET Energy from a trading firm into a technology company.
04 · Today
CetAI and TekAI
Today we apply that technology for municipal utilities: load forecasting optimisation and AI services in Germany and France through CetAI, and AI services in Switzerland through TekAI.

Values

What we stand for.

Integrity

We operate transparently and hold ourselves to high standards of conduct and governance. Utilities trust us with their data and with forecasts that feed into real operational decisions, so how we behave matters as much as what we deliver. We are clear about what our models can and cannot do, we honour our commitments, and we treat data protection and confidentiality as a precondition for doing business, not a box to be ticked afterwards.

Rigour

Decisions are evidence-led. Conviction at CET Energy has to be earned with data, not asserted with confidence: every model is validated on data it has never seen before it reaches a customer, and measured honestly against what actually happened. We would rather discard a promising idea that fails out-of-sample than defend it because it feels right. The same discipline applies after go-live — we monitor accuracy continuously and feed what we learn straight back into our models and processes.

Ownership

We build what we rely on and take responsibility for outcomes. Our models, data pipelines and infrastructure are designed, operated and understood in-house, rather than rented from third parties whose behaviour we cannot see into. Data scientists, engineers and energy specialists work as one team and share responsibility for results — good and bad. When something breaks we fix the root cause, when something works we make it repeatable, and nobody hides behind a hand-off.

Careers
