How Does The Wholesale Electricity Market Work?

Generators of electricity compete by offering electricity to suppliers in the market. This creates price competition. In times of shortages, this drives the wholesale electricity prices up as witnessed in the above graph. Suppliers will then re-price the electricity and sell it to businesses and households.

National Grid Electricity Transmission (NGET) manages the wholesale electricity system.

Unpredictable weather in the UK puts larger demand on the National Grid. Colder spells lead to greater usage.

Can Businesses Buy Directly From The Wholesale Market?

Some large businesses with very high consumption levels purchase their electricity and gas on the wholesale market. All other businesses must choose a supplier to manage their usage.

Should I Renew My Business Electricity Contract Now?

We advise businesses to compare electricity every six months to a year. Suppliers regularly update prices and tariffs as wholesale electricity prices are highly volatile. This means that a better energy deal could always be available.

If you let your energy contract roll over and fail to renegotiate, prices can increase by as much as 120%.

The contract extension will happen automatically if you don’t renew correctly and for most businesses, this will increase rates.

You can access business electricity quotes from a wide range of suppliers in seconds by comparing prices.

We make finding the right electricity tariff for your business simple.
