Your electricity bill explained

Your Go Power account reference. This is the one to have handy whenever you phone or email us.

The invoice number, unique to this bill. Quote it if you have a query about this specific invoice.

The date we issued the bill — always the last day of the month of supply. Your payment is taken 21 days later.

The days this bill covers. We bill monthly in arrears, so this bill is for electricity you used during the month shown.

Meter Point Registration Number. The unique number for the electricity connection at your premises. It belongs to the property, not to you — quote it whenever you contact us, NIE Networks, or a new supplier.

Use of System. The heading for the network charges that NIE Networks and SONI levy for carrying electricity across the distribution and transmission networks to your meter.

The code that tells you which of the five Go Power bill layouts you are looking at. This meter is T022, a day & night meter. The full list of codes is in the selector at the top of this page.

Where the electricity was delivered. It can differ from the address the bill is posted to — useful if a head office pays for several sites.

Where your meter stood at the start and end of the period, one column per register (Day and Night). The code in brackets tells you the source: (AR) an actual read, (ER) an estimate. Units used on each register are the closing read minus the opening read.

Our Supplier Management Fee — the one and only charge Go Power takes for supplying you. It is fixed for your whole contract term and charged per kWh you use. It is charged on your total usage across both registers: 1,822 kWh × 1.0000p = £18.22.

The electricity itself, for the hours that fall in the Day band. Under our Cost Plus model this rate is the wholesale market cost of power for those hours — we add no margin to it. All of it is 100% green. 1,252 kWh × 17.0300p = £213.22.

The electricity itself, for the hours that fall in the Night band. Under our Cost Plus model this rate is the wholesale market cost of power for those hours — we add no margin to it. All of it is 100% green. 570 kWh × 18.0000p = £102.60. Night energy is not always cheaper than day energy — it depends on what the wholesale market did in those hours.

A fixed daily charge from NIE Networks for keeping your connection live, your meter registered and the network available to you. You pay it whether or not you use any electricity.

The cost of getting the electricity you used in the Day band to your meter, and of running the market that supplied it. It is a single bundled rate: distribution charges from NIE Networks, transmission charges from SONI, and the Single Electricity Market charges collected through SEMO. All are published in advance, approved by the Utility Regulator, and identical for every supplier — Go Power adds nothing to them. 1,252 kWh × 14.1500p = £177.16.

The cost of getting the electricity you used in the Night band to your meter, and of running the market that supplied it. It is a single bundled rate: distribution charges from NIE Networks, transmission charges from SONI, and the Single Electricity Market charges collected through SEMO. All are published in advance, approved by the Utility Regulator, and identical for every supplier — Go Power adds nothing to them. 570 kWh × 9.2600p = £52.78. Network charges are markedly lower at night, when the system is less busy.

Climate Change Levy — a UK Government levy on business energy use, set by HM Revenue & Customs and charged per kWh. Relief applies to some qualifying and low-usage supplies, in which case the line does not appear. 1,822 kWh × 0.8010p = £14.59.

Every charge line above, added together, before VAT. £582.24.

VAT on the sub total. Business electricity in Northern Ireland is charged at the standard rate of 20%. A reduced 5% rate applies instead to low-usage and qualifying supplies — HMRC sets which applies, not Go Power.

Sub total plus VAT. This is what this month’s electricity cost you. £698.69.

Anything still outstanding — or in credit — from earlier bills. A figure in brackets is a credit in your favour and is deducted from what you owe.

This month’s total, carried down from the charges block above.

Previous balance plus this period’s charges. This is the figure that will be collected.

Your rolling 12-month consumption, or since you joined us if that is less. Useful for budgeting and for getting comparable quotes at renewal.

A fixed daily charge from NIE Networks for keeping your connection live, your meter registered and the network available to you. You pay it whether or not you use any electricity.

Maximum Import Capacity. You reserve a level of capacity at your site — 120 kVA here — and NIE Networks charges for it whether or not you draw on it. If your actual demand is well below the reserved figure, ask your account manager about reviewing it: the maximum demand printed on page 2 tells you what you actually used.

All the Use of System lines added together — the standing charge, the capacity charge and the four band charges. This is what the network operators receive for delivering your electricity.

A Government levy set annually by the Utility Regulator to fund energy policy commitments. It can be a charge or, as on this sample, a credit — the rate is negative, so £52.62 comes off your bill.

The cost of the services that keep the grid stable second by second — reserve, frequency response and voltage control. These are procured and charged by SONI, the transmission system operator for Northern Ireland, and passed through to you unchanged.

Funds the Northern Ireland Renewables Obligation, the scheme that supports renewable generation. Every supplier collects it at the same rate.

An adjustment applied by SONI that reconciles amounts over- or under-collected in earlier periods. It can be a charge or a credit — here it is a credit of £16.07.

The four levy lines netted off against each other. None of this money is Go Power’s — we collect it and pass it on.

Covers the cost of running the grid within its physical limits — constraining generators on or off when the network cannot carry what the market scheduled. Set by the Single Electricity Market Operator.

The cost of running the electricity market itself — trading, settlement and metering data systems operated by SEMO.

The Single Electricity Market settles in euro, so amounts have to be converted to sterling. This line passes through the cost of that conversion.

Spreads across all suppliers the difference payments that arise under the market’s capacity arrangements. The rate is zero on this bill, so nothing is charged — but the line still prints.

Funds the capacity market — payments that keep enough generation available to meet peak demand. It is charged on your usage during the peak-risk periods, which is why the units here are lower than your total consumption.

The five market lines added together. SEMO is the Single Electricity Market Operator, which runs the all-island wholesale electricity market.

Climate Change Levy — a UK Government levy on business energy use, set by HM Revenue & Customs and charged per kWh. Relief applies to some qualifying and low-usage supplies, in which case the line does not appear. 15,660 kWh × 0.7750p = £121.36.

A one-off charge passed through when detailed metering data is requested from the network operator. It only appears when such a request has been made in the period.

Every charge line above, added together, before VAT. £3,710.26.

VAT on the sub total. Business electricity in Northern Ireland is charged at the standard rate of 20%. A reduced 5% rate applies instead to low-usage and qualifying supplies — HMRC sets which applies, not Go Power.

Your payment date — 21 days after the end of the month of supply. Taken by Direct Debit, so you need do nothing.

Page 2 of a half-hourly bill. Every day of the month is broken down across the same time bands used in the charges, so you can see exactly when your site draws power. The bottom row totals each band — and those totals are the figures used on page 1. (Abbreviated here; your own bill lists every day.)

How efficiently your site uses the power it draws. 1.00 is perfect. A materially lower figure means your equipment is drawing reactive power, which can be worth correcting — your account manager can advise.

The highest half-hourly demand recorded in the month, in kVA. Compare it with your MIC on page 1: if maximum demand sits well below the capacity you are paying to reserve, there may be a saving available.
