Workstream Products

Open Networks Project - Workstream Products

This page is to be used as a dissemination point for the products emerging from the workstreams of the Open Networks Project. This page will be regularly updated with products as they become available. Many of these products have been reviewed by the project's Advisory Group, which includes a range of stakeholders from across the energy industry. As a reminder, you can find an overview of the Open Networks Project here and more about stakeholder engagement here, including consolidated sets of stakeholder feedback and how we have incorporated this into the products.

 

Workstream 1: T-D Process

Product 1: Mapping Current SO, TO and DNO Processes can be found here.

Product 1: Key Learnings from trial projects can be found here.

Product 7: The Data Template can be found here.

The Data Template sets out the information required by the SO/TOs from each DNO in order to undertake the necessary system studies which will determine planning limits at GSPs. A subset of this data will also form the basis of the data exchange between the DNOs, SO and TOs when managing DG contracted to connect under the new proposed process, the impact on the transmission system and the agreed planning limits.

Product 7: Statement of Works Customer Journey Maps can be found here.

The Customer Journey maps set out the current SoW process along with the data exchange and process flows, together with the new proposed process which will establish planning limits at each DNO GSP, new contractual arrangements between the DNOs and SO and the resulting customer benefits. It should be noted however that the customer journey map reflects the process where a planning limit has been established. Where further studies are required in order to determine a new panning limit, this will require the DNO to submit a Modification Application to the GBSO.

 Product 2: Gaps & Issues Analysis - Investment Planning can be found here.

Product 5: Potential Whole System Operational Issues can be found here.

As the electricity system changes, moving to more active operation across all voltage levels, then some existing resilience functions may be affected. This report identifies at a high level some areas of whole system operability that need to be reassessed in light of future electricity system operation.

Product 7: GSP Planning Limit Roll Out Programme can be found here.

The GSP Planning Limits Roll Out Programme sets out the plan which has been developed and agreed by all DNOs, TOs and the GBSO to establish Planning Limits across the Transmission/Distribution boundary, and ultimately deliver the transition away from Statement of Works when assessing the impact of Distributed Energy Resources on the transmission system. The programme will provide visibility to all interested stakeholders as to where current trials are in place and timescales for wider roll out across GB. Any questions on the programme should be directed to the particular DNO for the network area in question. The GBSO is currently developing their proposals for the associated CUSC (Connection & Use of System Code) Modification with a view of initial presentation at the January TCMF (Transmission Charging Methodologies Forum) and CUSC Panel Meetings.
