Frequently asked questions
Common questions
Frequently asked questions about TOE conversion, EİVER thresholds and energy audit obligations.
What is TEP (tonne of oil equivalent)?
TEP is a standard conversion unit that aggregates electricity, gas, fuels and coal into one measure. Efficiency rules express yearly total consumption in TEP.
How is TEP calculated?
Each energy type’s yearly amount is multiplied by the official EİVER coefficient. Source TEP values sum to the yearly total.
What are EİVER obligation thresholds?
Industrial sites 1,000 TEP, commercial/service buildings 500 TEP, public buildings 250 TEP are references for audits and duties. Exact obligations vary by floor area and sector.
What does the 1,000 TEP threshold mean?
When industrial yearly energy reaches 1,000 TEP or more, audits, efficiency projects and related EİVER duties come into play. This tool is informational pre-calculation only.
