Tendering Engineer

The Green Frog group of companies are the UK’s leading owner and operator of fast response power generation, providing services directly to National Grid through the STOR and Capacity Mechanisms. The group has in-house capabilities to build and connect the new generation to the grid and is investing heavily in new forms of clean, fast responding power generation technology.

The group is experiencing a high level of growth which is expected to continue for the foreseeable future as large scale, carbon intensive power plants continue to be de-commissioned and high volumes of intermittent renewable energy are brought on line. Our power plants plug the gaps between the old and the new, helping to provide a clean and stable electricity supply.

Green Frog Connect is the construction arm of the group and an accredited Independent Connection Provider (ICP), which allows us to design and build HV electricity networks at voltages up 132,000 volts. We take each project from concept, through detailed civil, electrical and mechanical design, construction, commissioning and finally handover to one of our sister companies for operation and maintenance.

Green Frog Connect also works for external clients either acting as ICP or EPC for new build renewable and conventional power generation. We have become one of the leading companies specialising in this sector and are the go-to people for clients looking for complex schemes to be connected to the grid within challenging timescales. In the last year alone we have connected over 200MW of power generation to the grid, and have a further 200MW in design and construction.

We are looking for highly motivated people to join our team at this exciting time, to grow and prosper within the company.
