Half Hourly Electricity: A Full Breakdown

by Sarah Wilkinson
 

Every day in the energy market things are changing, it can get a little frustrating from time to time trying to keep up with the new rules and regulations. We don’t want you to feel left in the dark regarding half hourly meters. Therefore we have tried to break it down as best we can to hopefully ease your mind.

Essentially, sites with a pinnacle load above 100kW are required to be introduced to a half hourly (HH). Half hourly meters can also be referred to as 00 meters. HH record data from consumption every 30 minutes – this information is communicated to the Supplier.

Half hourly meters can be found in a stretch of economic sites

 

Ranging from call centres, manufacturing sites, supermarkets all the way to sites which consume as much as places like Manchester Airport, half hourly meters can be found everywhere! Over 160, 000 sites are affected by this so it is definitely worth checking if you are part of this large number, further explanation on finding out how can be found below. If your site requires a HH it is vital you have a Meter Operator (MOP).

MOP is an organisation in the energy industry who hold the responsibility for installing and maintaining electricity and gas meters. They also provide the technical meter details to the Data Collector to enable collection of consumption data.

A HH Data Collector is in charge of collecting HH consumption data from the meter. The data is then certified and passed to the supplier for billing. HH meters allow you to understand your consumption and provides you with a reliable source of information for your businesses energy management. What more could you ask for? HH meters can be a great way to save your business money for other beneficial investments.

Finding out if you have a HH meter is easy. All you have to do is check the number next to your supply number marked ‘S’ – if the number reads 00 then you have a half-hourly meter.

Pricing for HH can vary. The following charges may appear on your bill if you have a HH Meter:

  • Energy Charges: based on your usage, usually split between day and night. Once you are on a HH meter, you should never receive an estimated bill. This is measured in kWh.
  • Capacity Charges: this charge relates to the Available Capacity for your site. The Average Capacity is the demand for your site which is agreed with the Distribution Network Operator (DNO) and they ensure this is available to you.
  • Reactive Power Charge: this is the difference between the working power and the total power consumed. If a site has a high reactive power, more current has to flow to provide the same output. This means more capacity has to be provided, potentially increasing costs for DNO.
