Smith Brothers ensures successful energisation of four turbine windfarm

four turbine wind-farm

Another extensive electrical infrastructure project has come to a close for a long-standing renewable energy client. Smith Brothers has just completed a six month assignment for REG Windpower and Western Power Distribution, on the Mynydd Brombil windfarm in South Wales.

The end-to-end design, build, installation and commissioning contract required a turnkey approach from our multi-disciplined high voltage engineers. For example, we:

  • Executed the balance of plant contract on time and to budget
  • Undertook complex on-site proving and trenching works, which wasn’t easy given the need to navigate neighbouring welsh mountains!
  • Installed a brick-built 33kV combined DNO and customer main substation
  • Supplied and installed all switchgear, transformers, cable infrastructure and SCADA cabling
  • Executed all testing and commissioning.

The result is a 33kV connection to the four turbine 8.88MW site.

This is the 12th project Smith Brothers has completed for REG, but our expertise proved particularly helpful on this site. WPD’s main contractor had an incident on the route, but was unable to provide an engineering solution within the client’s timeframe. We therefore worked with our specialist subcontractor to devise a solution and complete this section of works instead! This ensured the connection date remained feasible and the site was energised as originally scheduled.

Delivery of the Mynydd Brombil works comes hot on the heels of another successful six month project for REG Windpower in Peterborough, which the Smith Brothers team completed last autumn. We also achieved renewed status on the certified WPD framework earlier this year, which allows us to carry out non-contestable work on behalf of this DNO, up to 33kV.
