The Project

Balance of Plant Contract - engineering, design, construction and installation of civil and electrical infrastructure at Frodsham Wind Farm, Cheshire.

The wind farm comprises nineteen Nordex N90 WTGs, which stand at 125m in height (including blades). Each bespoke WTG will generate up to 2.65MW capacity, which will equal a total of over 50MW installed capacity across the site as a whole.

CHC was appointed as Principal Contractor throughout the Balance of Plant works, these works included;

  • Design and construction of 19 wind turbine foundations, incorporating Nordex anchor cages on complex and difficult ground conditions associated with the former use of the site for canal dredging deposition
  • Design and construction of foundations for the met mast
  • Design and construction of all associated roads and crane hardstandings
  • Design and build of two substations, including all associated drainage, oil interceptors, rainwater harvesting tanks, septic tanks and ancillary structures
  • All electrical works outside of the DNO scope, including all inter-turbine cabling, turbine earthing, providing the customer switchgear and transformers and FO communications for all turbines
  • Creation of a habitat creation zone
  • Working closely with contractors and operators of adjacent COMAH sites
  • Principal Contractor during the turbine erection, commissioning and testing stages 
  • Design and construction of various load spreading slabs to allow access over various services around site
  • Design and installation of a new bridge crossing over the Hool Pool Gutter
  • Installation of approximately 3km of suitable fencing and gates around site

Located close to the Mersey Estuary and the Manchester Ship Canal, the site is an important ecological area and complex in terms of ground conditions, aquatic habitat and the vast array of aquatic and terrestrial species that reside there. Protection measures were implemented for an array of species including badgers, water voles, eels and varieties of nesting birds such as the Eurasian Marsh Harrier. 

An active approach to sustainable procurement and integration of the local supply chain was implemented on this project. Working together with client Peel Energy and Cheshire West and Chester Council, we involved local employees, suppliers and subcontractors in the project wherever possible. This resulted in almost £1,000,000 being spent within the local area.

The project received a CEEQUAL Excellent Whole Team Award and was the first construction site in the UK to achieve a Biodiversity Benchmark: Design for Construction Award from the Wildlife Trust.
