Finally some good news from the DNO, SSE are stopping charging for network assessments unless there are more than 6 installations at one site or over 4kWp on one phase. We will still have to pre-apply though if over 3.7kW.

Here's the text of their email:

Introduction:

We are writing to all known Installers of SSEGs operating in the Southern Electric Power Distribution (SEPD) franchise area to inform them of some important changes to the connection application processes. These changes, which are to be introduced for a trial period of six months, will simplify the application and assessment process and reduce the cost of connection for some installations. If successful, the revised arrangements will become normal practice.

During the last three months we have been monitoring the impact of SSEGs connected to SEPD's low voltage network. This exercise focussed on our obligations to comply with the Electricity Safety, Quality and Continuity Regulations. Amongst other things, these Regulations place an obligation on us to fully assess the impact of any source of energy greater than 16 amps per phase (at 230/400 volts) which may be connected in parallel with our electricity network. The monitoring exercise, which was completed at the end of last week, provided enough evidence to suggest that most (but not all) of SSEGs can be connected without the need to carry out our usual detailed analysis.

The combination of the results of our monitoring exercise and the experience of using our modelling tool has given us the confidence to simplify our current arrangements.

The trial:

We have therefore reviewed our internal process for the trial period where we will carry out a limited network study for those SSEG applications where the maximum number of individual installations is six. This has allowed us to suspend our charges for carrying out network studies for these categories of SSEG for the duration of the trial. but we reserve the right to re-introduce these charges at any time should we find that it becomes necessary to revert to carrying out a full and detailed network analysis. Our main objective is to speed up the application process for our customers while, at the same time, continuing to ensure that all connections to our electricity network comply with the Regulations.

The revised arrangements in more detail:
 
Sorry, didn't manage to get the whole thing posted together...here's the full version

This has allowed us to suspend our charges for carrying out network studies for these categories of SSEG for the duration of the trial. but we reserve the right to re-introduce these charges at any time should we find that it becomes necessary to revert to carrying out a full and detailed network analysis. Our main objective is to speed up the application process for our customers while, at the same time, continuing to ensure that all connections to our electricity network comply with the Regulations.

The revised arrangements in more detail:
  • For all single G83 installations (i.e. <3.7kW), Installers should continue the current arrangements of connect and notify us within 30 days of commissioning.
  • For the connection of single and multiple installations between 3.7 kW and 50kW, Customers / Installers should continue to apply in the normal way using our existing application form (attached)
  • .
  • We will carry out a limited network study for single installations up to 4kW and for multiple installations up to a maximum of six where the the output of any single installation is 4kW or less and the multiple installations are balanced across all the available phases, i.e. L1, L2 and L3. Our connection offer for these applications will be free of charge where there is no requirement for work to take place to, for example, reinforce our network to allow the connection.
  • We will continue to carry out full network studies for those applications that are greater than 4kW, or multiple installations of more than six (regardless of output) in a particular postcode. Our connection offer will include our normal charges for network studies or, if applicable, any network reinforcement necessary to allow the connection.
  • These new arrangements will be introduced with immediate effect, i.e. for all applications processed from the beginning of this week - 18th July.
  • We recognise that suspending charges may seem unfair to those customers who have recently accepted our connection offer and paid for a full network study. We regret this may be the case, but we have to draw the line somewhere. Our formal charging arrangements require us to recover our costs for providing various services and we are not allowed to discriminate between customers and classes of customer. In these circumstances the line had to be drawn between customers where we had carried out a full network study on their proposed installation and those, going forward, where we will perform a limited network assessment.
  • It should be noted that our connection offers are valid for up to 30 days from the date of issue. Any existing offers which have lapsed will need to be re-quoted under these revised arrangements.
I hope the information provided above give clarity to our revised arrangements.
