At MECS we understand the necessity of a detailed and complete testing and commissioning regime to ensure that the commissioning phase is not only completed on program but also thoroughly proven and correctly documented.

Our Commissioning resource is highly experienced with a comprehensive understanding of the generation, transmission and distribution schemes and equipment required for 6.6kV, 11kV, 33kV, 132kV, 275kV, and 400kV power systems.

We have successfully completed test and commissioning works on significant projects within the Regional Electricity Companies (REC), DNO, National Grid, and private industry sectors.

With our commitment to maintaining up to date training, authorisations, accreditations, calibrated test equipment and familiarity with health & safety requirements we continue to meet and often exceed our clients testing and commissioning expectations.

The commissioning team encompasses authorisations with National Grid (including TP141 Advanced), United Utilities and EDF Energy. Combined with ECTIB Safety Passports, first aid, IOSH and CDM training this provides the ability to service client’s requirements in all of these areas as well as the private sector. An additional and rather unique enhancement is that our commissioning resource also hold Senior Authorised Person (SAP) accreditation with UU and EDF.

We offer a comprehensive service thorough expertise and skill base in a wide range of areas covering various manufacturers’ products, some examples of which are listed below:

  • Gas Insulated Switchgear (GIS) and Air Insulated Switchgear (AIS).
  • Electro-mechanical and micro-processor based relays utilised on Transmission, Distribution and Generator protection schemes (including 61850 applications)
  • Feeder protection (Unit, O/C & EF, Distance)
  • Transformers and Reactors
  • Plant Interlocking Schemes
  • AVC and DAR Schemes
  • Busbar Protection on Mesh corner and double Busbar substations
  • Gas Insulated Switchgear (GIS) and Air Insulated Switchgear (AIS)
  • MSCDN Capacity voltage control systems
  • Operation of secondary injection Testing equipment, including Programma, Omicron and RES Apts.

Our commissioning services are available on various flexible terms, from competitive time and materials basis to fixed price contracts. Our goal is to provide a full and economic solution without compromising quality.
