Major customers

Of the 190,000 customer connections to our network, approximately 470 of these are major customer connections. While major customers make up only 0.2% of our customers by number, they use around 25% of the total electricity that we deliver on our network.

What is a major customer?

  • To qualify as a major customer, a business needs to have a maximum demand for electricity of at least 250kVA. This compares to the maximum demand of a typical house of about 10kVA.
  • A major customer typically has a dedicated transformer, rather than using our low voltage network.

Pricing for major customers

Our pricing for major customer connections aims to reflect their more limited use of our network and the economies of bulk delivery. We are also able to make use of highly accurate time-of-use metering for major customers, which not only measures how much energy is used, but also records when it is used.
