Generation at 50kW and above

Quotation

Once you apply, we will acknowledge receipt, register your application and allocate it to one of our design engineers. Our design engineers will carry out a network study to find a suitable point of connection. These studies will highlight if the network can support your connection, or if reinforcement and diversion works are needed.

Depending on the area and loading of the network, a connection which may be classed as Low Voltage (LV), High Voltage (HV) or Extra High Voltage (EHV) We assign different timescales for LV, HV and EHV studies and quotations.

As our quotation options range from detailed and accurate quotations through to high level indicators of cost, the level of information we need to complete your quotation will vary.

Before you apply by post or email, please view our online checklist to ensure you have all the required information to apply. If you already have generation at your site, check your total capacity (including new and existing generation). Please review our fully completed G99 application form before applying.

If your installation is greater than 150kW and you are unable to complete part four of the G99 standard application form when you apply, please note we will require part four to be completed post acceptance and prior to energisation.

We request all generation applications over 200kW to include a Letter of Authority from the land owner.

Acceptance

If you want to progress with your quotation, you will need to complete and return the acceptance form (sent with the quotation) and pay. We will then contact you to discuss the next steps including: legal consents, road closure lead times and further network checks. For more information read our Business Connections Post Acceptance Pack which summarises the information you may need to provide for your project and what you can expect following acceptance. For all generation acceptances at 50kW or above, you will be required to adhere to project milestones and will be subject to the Queue Management process as described here.

Transmission impact assessment

All generation acceptances at 1MW or greater must be submitted to National Grid. Electricity North West have been working with National Grid to convert all of our Grid Supply Point interfaces from the Statement of Works process to the ‘Appendix G’ process. This will provide both a clearer picture of available transmission headroom and quicker formalisation of allocated transmission capacity, following offer acceptance. A guide to the appendix G process is available here. The current GSP headroom table can be found within the Heatmap Tool, available here.

Land consents

You will need to check if your connection requires legal consents and make sure that you have these in place, before work starts on site. Legal consents generally take a minimum of 12 weeks to complete and can be prolonged depending upon the grantor. We are unable to energise your connection until full consents are granted. For further information please see our legal consents information and process flow charts.

Delivery

We will endeavour to project manage the construction work to deliver the project in line with your preferred connection date. If necessary we will liaise with the Highways Authority and relevant landowners, to ensure that we can carry out the work as quickly as possible for you. To set up your supply, you need to choose an electricity supplier who will then install your meter and apply for a Meter Point Administration Number (MPAN). Following installation, the new assets must be tested and commissioned. The process can differ between LV, HV and EHV metered connections. Your installation shall also need to be G99 compliant.
