# Is it worth moving my small factory from an LT to an HT electricity connection?

Often, once load is large enough. HT energy rates are usually lower, but you must buy and maintain a transformer, and its losses fall on your side of the meter. Emissions per kWh do not change; your Scope 2 counts the units your meter records.

## What to compare

- Energy and demand charges under both tariffs for your monthly load.
- Transformer, switchgear and civil cost, and annual maintenance.
- Transformer no load and load losses, metered on the HT side.

## Emissions view

An efficient transformer cuts the extra units you pay for. Choose a high efficiency rating; the losses run every hour of the year.

## What Senseible does here

Senseible reads electricity bills, including kVAh, demand and solar export lines, into dated records with the units, factor and year behind every Scope 2 figure.
