This page provides information and links for the connection of all additional generation equipment at the Park Ecovillage, Findhorn.
Connection of all generation equipment (including domestic scale PV) must comply with the version of EREC G99 current at the time of commissioning. Generation equipment includes PV systems, batteries, vehicle to grid capable EV charge points and any other source with the potential to supply electrical power to the grid.
Visit https://www.energynetworks.org/ and search the site for “G99” to access the current standards and the relevant forms to be completed. Connections at the Park fall into the G99 type A generating modules category.
Energy Networks Association Applications
Depending on the installation, an Energy Networks Association (ENA) application may need to be submitted. At the time of writing there is no facility to apply for a connection amendment. Instead, a new connection must be applied for that includes all the existing generation systems on the MPAN.
This is an expensive and lengthy process that requires technical knowledge. FWP will be the formal applicant, but Installers and/or consultants will need to work with FWP to prepare the application. FWP’s costs in preparing an ENA application are chargeable.
There are also costs associated with processing an ENA application by the DNO that will be charged to the project by FWP:
- The ‘cost of offer expenses’ part is charged by the DNO, even if the project does not go ahead.
- A connection offer is valid for 90 days. ‘The project’ must reach agreement with FWP on payment of the connection charges before FWP will accept the binding terms of the DNO offer.
Please get in touch to discuss your plans using the technical contact page at an early stage.
Domestic Scale PV, Batteries and G100
Where these installations can normally be connected under G98, they can go through a ‘fast track’ process provided the inverters are certified for G99. Where batteries are to be installed a G100 mode should be used or a separate G100 system installed covering the entirety of the private installation.
Only one system can be added at a time, so your installation may be delayed if another system is in process. Please get in touch using the technical contact page. We will require a single line diagram of the proposed installation including the following:
- The number of phases and the fuse rating of the proposed connection to the NFD network.
- Any existing battery, PV array or other source of generation.
- Clearly distinguish DC and AC lines.
- Clearly distinguish existing equipment and proposed new equipment.
- The maximum power rating of any PV array (or other generation equipment).
- The specific model number(s) for the inverter(s) and the compliance certification for that model.
- The specific model number for any battery and the compliance certification for that model.
- The maximum export to the NFD network.
- Details of any G100 system employed to limit the export including the compliance certification.
- Screen shots from the ENA type test register for each device to be fitted showing compliance with G99 Type A. These should be included in the same document as the single line diagram. Note that the following example is not compliant at the Park Ecovillage:
