Grid Connection Support Projects

G99 Grid Connection Application for 50MW+ Wind and BESS, Client: Confidential (2022)

We prepared the full G99 grid connection application for a 50MW Wind and BESS submitted to a Scottish DNO. This included preparation of the full application, the detailed Single Line Diagram (SLD), and the necessary fault level contribution and reactive power calculations.

We also supported in the formal engagement with the DNO prior to the submission of the application to understand the timescales, cost and constraints associated with the connection application. The application was successfully submitted to the DNO and accepted without issue.

Transmission Grid Connection Application for 110MW+ Wind and BESS, Client: Confidential (2022)

The preparation of all necessary Transmission grid connection documentation for a large onshore wind farm with co-located BESS. This included a detailed Single Line Diagram (SLD) and the development of a simple power systems model of the wind farm to calculate the various technical parameters required within the DRC.

We also supported the pre-application engagement with the ESO and Transmission Operator to discuss the cost, timescales and constraints associated with the connection application and the various connection options.

“Blake Clough has a professional approach in interactions with contractors and NGESO & efficiently chaired / facilitated multi-contractor meetings to ensure that all participants remained focused on the purpose of the meeting & developed a clear action plan to deliver the necessary results.”

G99 Grid Connection Application for 100MW+ Solar and BESS, Client: Confidential (2021)

We prepared a full G99 grid connection application for UK developer of 50MW of BESS and Solar. This included preparation of the full application, the detailed Single Line Diagram (SLD), and the necessary fault level contribution and reactive power calculations.

The application was successfully submitted to the DNO and accepted without issue.

G99 Grid Connection Application Guidance, Client: Confidential (2022)

We supported this client to better understand the technical and commercial data required to successfully prepare a compliant G99 grid connection application.

We prepared an example application for a 50MW solar farm and explained the various sections of the application form and the level of detailed required to complete a compliant application that will be accepted by a DNO.

Solar, Wind, BESS Grid Capacity Scouting and DNO Engagement Support: Client: Various (2021-2022)

We have been supporting various Developers in Great Britain looking for high potential points of connection to the Transmission and Distribution network for new BESS, Solar and Wind development of various sizes.

This work included the analysis of various data sources including generation Heat Maps, Long Term Development Statements, Network Development Plans, Google Maps, prior to engagement with the relevant DNOs on the shortlisted points of connection.

During the engagement with the DNO we gathered valuable information relevant to any future grid connection applications to fully understand the timescales and costs associated with any new connections.
