Hornsea services
Gas can be withdrawn at a rate of upto 18 million cubic metres per day, equivalent to the requirements of around four million homes. The services offered by our subsidiary company, SSE Hornsea Ltd, provide customers with a reliable source of flexibility with which to manage their supply/demand balance and exploit market opportunities.
Firm services
The basis of the Hornsea storage service is the Standard Bundled Unit (SBU). Each SBU comprises 1kWh of Deliverability, 0.110769kWh of Injectability and 17.948718kWh of space. SBUs are currently sold for a minimum term of 1 storage year (1 May - 30 April).
Interruptible services
As well as selling firm storage services, SSE Hornsea Ltd also offers customers access to unused firm capacity allowing them to inject, store and withdraw gas on an interruptible basis. Interruptible services are also available to customers who do not have firm capacity provided that they have signed the standard Storage Services Contract and Credit Agreement.
Commodity charges
Customers pay a fixed capacity charge over the duration of their storage booking. Commodity charges are payable for each kWh injected and withdrawn.
Storage services contract and credit agreement
SSE Hornsea Ltd storage services are currently sold under the terms of the standard Storage Services Contract and Credit Agreement for a minimum period of one storage year (1 May – 30 April).
Physical service
Unlike virtual or NBP type storage services Hornsea customers are able to access unused or spare physical capacity via interruptible services. Customers can also further add value via the OCM, trading locational gas with the System Operator.
Within-day flexibility
Customers can react quickly to the volatile within-day gas market and balance changes to their supply/demand position during the gas flow day.
Short lead times
During the winter months (November – March) customers can withdraw their gas at one hour’s notice. Outside of this period the withdrawal lead time varies between one to four hours. The injection lead time is two hours.
Cycling storage space
Storage space can be cycled more than once. Thus after gas has been withdrawn from store, more can be injected and withdrawn, allowing customers to increase the value achieved from their firm capacity bookings. Interruptible services further increase the scope for recycling of storage space.
