Half-hourly energy monitoring

One day, read half hour by half hour.

The shape shows when demand runs. Missing and estimated periods stay marked rather than being smoothed over.

The cheapest energy is the energy you don't use

Make the data your meters already collect worth having.

Every half hour read and checked, not filed away behind a single total.

  • Every half hour read

    Usage read through the day, not reduced to one figure at the bottom of the invoice.

  • Baseload made visible

    Overnight baseload and out-of-hours plant are shown, not hidden in a monthly total.

  • Checked for gaps and estimates

    The data is verified before it is used, so a finding is never built on a period that was not actually measured.

  • Read against operation

    The pattern is set against how the site actually operates, not an assumed schedule.

Where it goes wrong, and what we do about it

  • How Omnium solves it

    We read how each supply is used in every half hour of the day, rather than letting the data sit unread behind the single total on the invoice.

  • How Omnium solves it

    The data makes overnight baseload and out-of-hours plant visible, checked against how the site actually operates.

  • How Omnium solves it

    The data is checked for gaps and estimates before it is used, so a finding is not built on a period that was never actually measured.

  • How Omnium solves it

    Monitoring does not reduce a bill by itself; it shows where the waste sits, and that finding feeds directly into the reduction work.

In short

Half-hourly monitoring reads how each supply is used in each half hour of the day, rather than relying on the single total at the bottom of an invoice. It makes the overnight baseload and out-of-hours plant visible, checked for gaps and estimates, and read against how the site actually operates.

What this does not do. Monitoring does not reduce a bill on its own. It shows where the waste sits, and the reduction comes from acting on the finding.

The first review across your invoices costs nothing. Later work is quoted and agreed in writing before it begins. Cost recovery

A high overnight load is not always waste. Some plant has to run.

Where a site's pattern is genuine, that is the finding. Monitoring does not save anything on its own: it makes waste visible, and the saving comes from acting on what it shows.

  • 01

    The half-hourly or AMR record for each supply, collected and checked for gaps and estimated readings.

  • 02

    The overnight baseload: what the site draws when it should be drawing almost nothing.

  • 03

    Out-of-hours plant: what is running outside the operating pattern, and when it starts and stops.

  • 04

    The demand shape against the opening hours, shift times and the plant that should be running.

  • 05

    Sites of similar use and size within your own estate, compared fairly, with what makes them comparable stated.

  1. The half-hourly or AMR record is gathered per supply, so the picture rests on readings rather than invoice totals.

  2. Gaps and estimated readings are identified and labelled. Where a meter reports nothing, that is stated rather than smoothed over.

  3. The data is read against the operating pattern: the hours, the shifts, the plant that should be running and the plant that should not.

  4. Findings are reported in writing, dated and attributed, and nothing proceeds beyond the report until you say it should.

Questions

What clients ask before starting

A record of how much electricity a supply used in each half hour of the day, rather than a single monthly total. It shows when the load runs, not just how much it adds up to.

Half-hourly and AMR meters already do. Smaller supplies are moving the same way under market-wide half-hourly settlement: migration began in October 2025, with around 80 per cent of meters expected migrated by October 2026 and full implementation in May 2027.

Most often an overnight baseload that is higher than the building needs, plant running out of hours, and demand patterns that do not match how the site is used. Where a site is genuinely peaky by nature, we say so.

The invoice gives one total at the end of the month. Monitoring reads the shape of use within it, which is where the waste sits. The two numbers reconcile, but only one of them tells you when to act.

We say so. Estimated readings are labelled as estimates, and where a meter reports nothing we record the gap rather than filling it with a modelled figure.

The first review of your invoices and data costs nothing. Ongoing monitoring is quoted and agreed in writing before it starts, as part of the management arrangement for the account.

How to check this

Each claim on this page is answered by something you can read for yourself. Nothing below states a figure; it names the document or register the claim is held against.

  • Point 01

    We hold a Level 1 Letter of Authority only

    The authority wording sets out what we may do with your data and states that we cannot sign a contract on your behalf. Read it before you sign it.

  • Point 02

    How we are paid is agreed in writing before you sign

    Our margin or management fee is stated in the terms that accompany a recommendation, and nothing is added afterwards.

    Client terms and conditions

  • Point 03

    Every figure we quote carries a dated source document

    Records state the figure, what it is measured against, the document it is taken from and the date on that document. Records still held anonymous are labelled as such.

    Evidence records

  • Point 04

    Consumption figures come from meter and supplier data, not estimates

    Where a reading is estimated or missing, the record says so rather than filling the gap.
