Electricity North West (ENWL) are shown to have secured restoration support - which involves supporting the network to reduce stress in the event of equipment failure - in the first half of 2019. Despite initial success, ENWL have been unable to procure flexibility for the remainder of 2019. This is likely due to tender responses from flexibility providers not meeting predetermined criteria, such as the minimum amount of flexibility. A review of the need for this flexibility, will be conducted for Alston, Coniston and Easton, this is set for completion in Autumn 2019. NPG and WPD are yet to publish their results, these being anticipated between September and October 2019. ...
