Demand turn up
The demand turn up service encourages large energy users and generators to either increase demand or reduce generation at times of high renewable output and low national demand. This typically occurs overnight and during weekend afternoons in the summer. Find out about routes to market as a provider.
2017 - The demand turn up (DTU) market is currently in its second year
The fixed DTU tender round closed on 17 February 2017. This was the first opportunity to participate in the 2017 service. Tenders were invited from demand side participants (both generation and load response) for contracts to provide the Demand Turn Up service for the duration of British Summer Time (BST - 27 April to 28 October) in 2017.
Tenders were received from nine companies, totaling 262.2 MW. In this tender round, 138.6 MW of fixed volume was accepted from six parties, based on prices submitted, speed of response, duration of response, and location.
As explained in the DTU tender rules, a second route to market is also available for participants who did not compete in (or were unsuccessful in) the fixed DTU tender round. Bi-weekly flexible assessments will be run to acquire additional volume in instances where the DTU requirement changes.
Alongside a cost comparison against the contracted fixed providers, flexible providers will be assessed against all alternative footroom actions to determine the most economical way to fill any outstanding requirement.
For the 2016 service period (May to September), we procured 309 MW of DTU.
The service was utilised 323 times between May and September, for a total of 10,800 MWh and an average utilisation price of £61.41/MWh.
National Grid and WPD joint report
As an additional aspect to the 2016 service, we participated in an innovative trial with Western Power Distribution (WPD), through which we procured and despatched DTU providers on behalf of both the system operator (SO) and distribution network owner (DNO) in order to meet transmission and distribution network requirements efficiently.
We have published a joint report to share learnings and participant feedback from the 2016 trial and to explain how the service and sharing trial is evolving for 2017.
