Half-Hourly metered sites  
 
Why do we have HH meters 
 
Many industrial sites as well as hotels and manufacturers will have Half-Hourly Meters (HH) to supply business electricity. There is a legal requirement for all sites that ‘draw’ in excess of 100KVA in any half hour period to have such meters installed. 
 
These meters were introduced in order for the suppliers, and the National Grid, to be able to monitor the level of demand across the countries larger business electricity users in ‘real’ time.  
 
The key differences  
 
• Your business electricity prices are priced from the open market. When your contract is being negotiated these prices will fluctuate each day. 
 
• Each meter has three contracts associated with it  
 
(1) the supply contract for the electricity  
(2) a MOP contract with the company that owns and maintains the meter  
(3) ‘availability’ contract with your local distribution company that states how much KVA you are entitled to. 
 
• Prices are based on the pattern of your usage with the HH data used to individually price each supply 
 
What we can do 
 
Your account manager will be able to provide prices based on your data and steer you through the complexities of the tendering process. As an extra service your account manager will provide you with indicative pricing at a mid point in you contract to allow you to manage your future budgets.
