What is a business electricity half-hourly meter?

A half-hourly (HH) meter automatically records your electricity usage every 30 minutes, creating 48 data points a day. For high-demand businesses (Profile Class 00), it is mandatory, so that billing is based on actual consumption rather than supplier estimates. Fidelity Energy collects that data and reports on it for you through the Etainabl platform.

What happens if a half-hourly meter loses its connection?

If a half-hourly meter loses its connection, the Data Collector cannot retrieve its 48 daily intervals, which leads to estimated settlement by the supplier. Proactive management means monitoring for these dial-up failures so communication modules are repaired quickly, maintaining the 99% data completeness required by the Balancing and Settlement Code. Fidelity Energy resolves communication faults proactively as part of its half-hourly data service.

Why do I need a dedicated Data Collector (DC) and Data Aggregator (DA)?

A dedicated, independent Data Collector (DC) and Data Aggregator (DA) gives you control over your half-hourly data. Appointing Fidelity Energy as your independent DC/DA agent means we collect and validate your 48 daily intervals, so the information sent to your supplier is accurate. That helps prevent overcharging, and communication faults are resolved proactively.

What is Market-wide Half-Hourly Settlement (MHHS)?

Market-wide Half-Hourly Settlement (MHHS) is a major UK reform moving the entire electricity market to half-hourly settlement. Fidelity Energy helps you through the transition, handling the P272 and MHHS changes so your business stays compliant and ready for the new regulatory standards. Being settled half-hourly also lets you access flexible time-of-use tariffs.

How does half-hourly reporting benefit ESG disclosures?

Half-hourly reporting makes ESG disclosures more accurate, because it tracks electricity use in near real time and gives a more precise calculation of Scope 2 emissions. That detail helps businesses meet SECR (Streamlined Energy and Carbon Reporting) requirements and gives a clear baseline for measuring the impact of efficiency projects. Fidelity Energy provides automated monthly half-hourly reports and live reporting through Etainabl.

Cut the energy your building uses when it's empty

A whole year on one page

Every half hour of the year, darker where demand is higher. The working day is the band across the middle; weekends are the pale stripes.

See what runs out of hours

In this example office, 38% of the electricity is used outside weekday working hours.

Find the baseload

The overnight floor runs all year. Every kilowatt taken off it saves around 8,760 kWh a year.

Compare a typical day

Weekday against weekend, half hour by half hour, shows which plant and lighting run while the building is largely empty.
