Glossary

The language of the work.

A short reference for terms used across Nohm’s product pages.

01

Scenario

A defined set of assumptions and conditions used to explore an energy-system question. A scenario is not a prediction or a guarantee.

02

Substrate

The aligned data foundation used across workflows: carriers, geography, markets, sectors and time-related assumptions.

03

Carrier

An energy form or vector represented in a study, such as electricity, hydrogen, gas or heat. The actual carrier set depends on model scope.

04

Granularity

The level of detail in a model, including geography, assets and time resolution. More detail changes data requirements and computation.

05

Climate year

A set of weather-related conditions used to explore how demand and renewable resources affect a scenario.

06

Run and lineage

A run is an execution or recorded analytical operation. Lineage connects its results to inputs, versions, assumptions and subsequent transformations.

07

Levelised cost

A cost-per-unit measure calculated under a defined methodology and assumption set. LCOE refers to electricity; LCOH commonly refers to hydrogen.

08

Approval gate

A point at which a proposed action needs authorisation before it proceeds. Interpretation of a request is not itself approval.

09

Atlas

Nohm’s map-led view of energy-system evidence. A visual display should be interpreted with its source, date and geographical scope.

10

Studio

A workspace for a class of tasks, such as analysis, visualisation or reporting, subject to product availability and user permissions.
