Why SEP.ask

Energy planning, as fast
as a question.

Natural language

Ask in German, French or English — no SQL. Direct answers from 1.5 billion data points.

Pinpoint accuracy for all of Switzerland

Every municipality, every building, every canton — fully covered by the Building & Dwelling Register, official cadastral survey, the solar cadastre and 40+ further validated sources.

Transparent & source-based

Every answer references the underlying SEP datasets — auditable and traceable.

Seamlessly integrated into SEP

SEP.ask is embedded directly in the existing Swiss Energy Planning platform — your existing SEP customer data is ready to use.

Use cases

Who is SEP.ask for?

From customer potential to target-grid planning

Identify buildings suited to heat pumps, with ageing oil or gas heating, or untapped solar potential — filtered by your supply area, prioritised and export-ready. For target-grid planning, simulate load scenarios directly on your network infrastructure.

Example questions
"Show all oil heating systems older than 15 years in my supply area."
"What would peak load on the distribution grid be if all oil heating were replaced by heat pumps and every roof had solar?"
"Which transformer stations are overloaded at 80% heat-pump penetration?"
"Where do bottlenecks arise in the low-voltage grid under full decarbonisation by 2040?"
"Show buildings with high heat demand along my planned district-heating route."
"Which neighbourhoods are suitable for local energy communities (LEC)?"
"How does annual energy per feeder change with 1,200 additional PV systems?"
"Which house connections must be reinforced for e-mobility?"
How SEP.ask works

From question to analysis – fully automated.
