Generation and storage

Generation and storage

Following a review of how battery storage connections are modelled on our network, ENWL have made the decision to revise how P28 limits are calculated and applied for new battery storage connections, with a view to releasing network capacity for batteries. Therefore, for all applications made on or after 3rd May 2022, these revised calculations shall be applied. Any application which is received prior to this date, including those battery application currently in our workbank, will still be modelled under the previous parameters.

We provide a range of generation connections including energy storage, from small domestic-sized installations through to large business and industrial scale generation projects.
