Roles Within Transmission Connections

SP Transmission (SPT)

SP Transmission is a Transmission Owner (TO). Whilst we retain ownership of our transmission assets, such as substations and transmission towers, we have a licence obligation to maintain, design, develop and deliver new or modified connections to our network.

National Grid Electricity System Operator (NGESO)

National Grid Electricity System Operator (NGESO) are the designated system operator (SO) in England, Scotland and Wales. As the SO, NGESO is responsible for ensuring the stable and secure operation of the whole transmission system. The SO is also responsible for balancing the electricity demand across the whole of Great Britain with electricity supplied by generating stations on a minute-by-minute basis. As the SO, NGESO provides transmission services to generators, electricity suppliers and large customers and will deal with all aspects of the contracts for the connection to and use of the electricity transmission system.

Heat Maps

Before we can connect you we have to make sure that our existing network is capable of providing the power you need to operate your equipment.

For smaller projects (smaller than or equal to 50kW) there is normally no need to worry about the capacity of our network but for larger projects we may need to carry out some work to connect your generator. We recommend that you engage with us at an early stage as it’s important that you are aware of the timescales and costs involved before you begin your project.

In advance of this we have a series of heat maps that will give you an indication of the networks capability and a better understanding of potential opportunities to connect your generator to the electricity network.

Pre-Application Customer Engagement (PACE)

We have streamlined our Pre-Application Customer Engagement process (PACE). Please complete our new PACE request form below to tell us about your project so as we can prepare some information on the type of connection we could offer prior to meeting with you. This can be for a connection directly into our Transmission Network or for embedded projects that require access to our Transmission Network. Once you have completed the PACE request form, please submit to transmissionconnections@spenergynetworks.com. We will then contact you with a time slot for our pre-arranged PACE surgery sessions held on a Tuesday afternoon.

Your meeting with us will take place a minimum of 2 weeks after you submit your PACE request form. You can expect colleagues from our System Design, Project Management and Commercial team to be in attendance along with colleagues from NGET ESO. At this session we aim to give you an overview of the type of connection offer you would likely receive in response to a connection application.

Charging Statement

SPT is obliged, under Special Condition (SC) 8C of its electricity Transmission Licence, to prepare a statement approved by the Authority setting out the basis upon which charges will be made for the provision of transmission services in such form and detail as shall be necessary to enable NGET to make a reasonable estimate of charges to which it would become liable for the provision of SPT’s services. These services include the planning, development, construction, maintenance and operation of new and modified connections to the licensee’s transmission system.
