Standard suite of storage service offers.

We modified our application forms to make it quicker and easier for customers to make a storage connection application.

We are committed to supporting the uptake of generation and storage and we are working with our stakeholders to understand what more we can do to help them get connected to our network. Battery energy storage systems (BESS) can be used in a number of different ways to provide benefit.

Some of our customers are using batteries to store the electricity they generate for their own use, whilst others are using a BESS to actively support the electricity network through commercial contracts. The two scenarios are very different and so is the cost of the connection. To help our customers obtain the right kind of connection, we have developed three standard storage arrangements covering self-consumption, reserve capacity and response services scenarios.

We developed these new arrangements with input from stakeholders and introduced them at the ENA’s DER Connections Forum in September 2017, where those attending had the opportunity to give feedback on what we were proposing. All of those who responded to the ENA’s survey rated our presentation as ‘excellent’ or ‘good’.

This new suite of standard storage offers is intended to make it easier for customers to identify the kind of connection they require and for our engineers to process their application. The new connections offers were introduced in March 2018 and we are yet to process any new applications.
