Penzance businesses and half-hourly supplies
The main town of west Cornwall, Penzance is the mainland base for ferry, freight and helicopter links to the Isles of Scilly. Tourism and hospitality underpin much of the local economy, supported by the harbour, the fishing industry at neighbouring Newlyn, and shops, cafés and services in the town centre. Small industrial estates such as Long Rock house trades, food producers and distributors serving the far west of Cornwall.
Many visitor attractions, hospitality venues, port businesses and food processors in and around Penzance are half-hourly metered, either because they draw more than 100 kW at peak or because they were moved over under P272. Their bills are built from 48 readings a day, plus network charges that change with the time of day.
Your local electricity network
The local distribution network in Penzance belongs to National Grid Electricity Distribution (South West area). You can confirm it from your bill: the bottom line of your MPAN starts with the distributor ID 22.
The network operator sets Distribution Use of System (DUoS) charges in time bands. In this area the red band – the most expensive – runs 17:00–19:00 on weekdays, according to its published charging statement. Amber covers the rest of the working day and green covers nights and weekends.
The capacity charge is easy to overlook. It is based on the kVA your network operator has reserved for you, not on what you use, so a twelve-month look at your half-hourly maximum demand often shows whether your Agreed Supply Capacity still fits.
What we do for businesses in Penzance
Our work is practical and starts with your bill. Typically we:
- Review your Agreed Supply Capacity and red-band use against twelve months of half-hourly data.
- Make sure your metering and data service contracts are in place and ready for MHHS.
- Compare half-hourly contracts from UK suppliers well before your renewal date, so you never fall onto out-of-contract rates.
- Check your bills line by line: energy rates, DUoS bands, capacity and excess capacity, reactive power, TNUoS, Climate Change Levy and VAT.
Whether your site is around Long Rock Industrial Estate and Newlyn Harbour or elsewhere in Penzance, the process is the same and it starts with a bill.
Every recommendation comes with the numbers behind it, drawn from your own half-hourly data, so you can see why it makes sense before you agree to anything.
Market-wide Half-Hourly Settlement in Penzance
Under MHHS, the industry is settling every meter on half-hourly data by May 2027. That makes accurate meter data and well-chosen contracts more valuable for businesses in Penzance – and makes peak-time use more visible in the prices suppliers quote. Our guide to understanding MHHS explains what to check.
Before your next renewal, it is worth confirming three things: your meter communicates every day, your metering and data agents are appointed and qualified, and your contract terms say how settlement changes affect your price.

Half-hourly electricity in Penzance: common questions
Who is the electricity network operator in Penzance?
National Grid Electricity Distribution runs the local distribution network in Penzance (South West area, distributor ID 22). It sets the DUoS time bands and capacity charges on half-hourly bills, and handles requests to change your Agreed Supply Capacity.
When is the DUoS red band in Penzance?
In the South West area the red band runs 17:00–19:00, Monday to Friday, according to the network operator’s charging statement. Electricity used then carries the highest network charges, so moving flexible loads out of that window can lower costs.
Does my Penzance business need a half-hourly meter?
If your site’s maximum demand goes over 100 kW in any half hour, it must be half-hourly metered and settled. Smaller sites are also moving to half-hourly settlement under MHHS by May 2027. If the top line of your MPAN starts with 00, you are already half-hourly.
Can you help if our Penzance site is out of contract?
Yes. Out-of-contract and deemed rates are usually much higher than contract prices. Send us a recent bill and we can ask UK suppliers for quotes quickly, then handle the switch and your metering and data contracts.
What does a free bill check include?
We compare every line of your bill with your contract and half-hourly data: energy rates, DUoS bands, capacity and excess capacity, reactive power, TNUoS, Climate Change Levy and VAT. You get a plain-English summary of anything wrong or worth changing.
